Return the playback position (in seconds) in an animation channel (or channel 0 if none is provided). Find an animation name by resource. The animation player creates caches for faster access to the nodes it will animate. However, if a specific node is removed, it may not notice it, so clear_caches will force the player to search for the nodes again. Set the mode in which the animation player processes. By default, it processes on idle time (framerate dependent), but using fixed time works well for animating static collision bodies in 2D and 3D. See enum ANIMATION_PROCESS_*. Return the mode in which the animation player processes. See [method set_animation_process_mode]. Get the position (in seconds) of the currently being played animation.

Return the index of the pressed button (by tree order). Return the focused button. Return the list of all the buttons in the group. Set the button to be pressed. Camera node, displays from a point of view. Camera is a special node that displays what is visible from its current location. Cameras register themselves in the nearest [Viewport] node (when ascending the tree). Only one camera can be active per viewport. If no viewport is available ascending the tree, the Camera will register in the global viewport. In other words, a Camera just provides [i]3D[/i] display capabilities to a [Viewport], and, without one, a [Scene] registered in that [Viewport] (or higher viewports) can't be displayed. Return a normal vector in worldspace, that is the result of projecting a point on the [Viewport] rectangle by the camera projection. This is useful for casting rays in the form of (origin,normal) for object intersection or picking. Return a 3D position in worldspace, that is the result of projecting a point on the [Viewport] rectangle by the camera projection. This is useful for casting rays in the form of (origin,normal) for object intersection or picking. Return how a 3D point in worldpsace maps to a 2D coordinate in the [Viewport] rectangle. Set the camera projection to perspective mode, by specifying a [i]FOV[/i] Y angle in degrees (FOV means Field of View), and the [i]near[/i] and [i]far[/i] clip planes in worldspace units. Set the camera projection to orthogonal mode, by specifying a width and the [i]near[/i] and [i]far[/i] clip planes in worldspace units. (As a hint, 2D games often use this projection, with values specified in pixels) Make this camera the current Camera for the [Viewport] (see class description). If the Camera Node is outside the scene tree, it will attempt to become current once it's added. Return wether the Camera is the current one in the [Viewport], or plans to become current (if outside the scene tree). Get the camera transform. Subclassed cameras (such as CharacterCamera) may provide different transforms than the [Node] transform. Perspective Projection (object's size on the screen becomes smaller when far away). Orthogonal Projection (objects remain the same size on the screen no matter how far away they are). Camera node for 2D scenes. Camera node for 2D scenes. It forces the screen (current layer) to scroll following this node. This makes it easier (and faster) to program scrollable scenes than manually changing the position of [CanvasItem] based nodes. This node is intended to be a simple helper get get things going quickly and it may happen often that more functionality is desired to change how the camera works. To make your own custom camera node, simply inherit from [Node2D] and change the transform of the canvas by calling get_viewport().set_canvas_transform(m) in [Viewport]. Set the scroll offset. Useful for looking around or camera shake animations. Return the scroll offset. Set to true if the camera is at the center of the screen (default: true). Return true if the camera is at the center of the screen (default: true). Make this the current 2D camera for the scene (viewport and layer), in case there's many cameras in the scene. Return true of this is the current camera (see [method Camera2D.make_current]). Set the scrolling limit in pixels. Return the scrolling limit in pixels. Set the margins needed to drag the camera (relative to the screen size). Margin uses the MARGIN_* enum. Drag margins of 0,0,0,0 will keep the camera at the center of the screen, while drag margins of 1,1,1,1 will only move when the camera is at the edges. Return the margins needed to drag the camera (see [method set_drag_margin]). Return the camera position. Force the camera to update scroll immediately. Base class of anything 2D. Base class of anything 2D. Canvas items are laid out in a tree and children inherit and extend the transform of their parent. CanvasItem is extended by [Control], for anything GUI related, and by [Node2D] for anything 2D engine related. Any CanvasItem can draw. For this, the "update" function must be called, then NOTIFICATION_DRAW will be received on idle time to request redraw. Because of this, canvas items don't need to be redraw on every frame, improving the performance significan'tly. Several functions for drawing on the CanvasItem are provided (see draw_* functions). They can only be used inside the notification, signal or _draw() overrided function, though. Canvas items are draw in tree order. By default, children are on top of their parents so a root CanvasItem will be drawn behind everything (this can be changed per item though). Canvas items can also be hidden (hiding also their subtree). They provide many means for changing standard parameters such as opacity (for it and the subtree) and self opacity, blend mode. Ultimately, a transform notification can be requested, which will notify the node that its global position changed in case the parent tree changed. Called (if exists) to draw the canvas item. Used for editing, returns an opaque value represeting the transform state. Used for editing, handle rotation. Return a rect containing the editable contents of the item. Return the canvas item RID used by [VisualServer] for this item. Return true if this CanvasItem is visible. It may be invisible because itself or a parent canvas item is hidden. Return true if this CanvasItem is hidden. Note that the CanvasItem may not be visible, but as long as it's not hidden ([method hide] called) the function will return false. Show the CanvasItem currently hidden. Hide the CanvasItem currently visible. Queue the CanvasItem for update. NOTIFICATION_DRAW will be called on idle time to request redraw. Set as toplevel. This means that it will not inherit transform from parent canvas items. Return if set as toplevel. See [method set_as_toplevel]/ Set the blending mode from enum BLEND_MODE_*.

Set the array of segments. Return the array of segments. Dialog for confirmation of actions. Dialog for confirmation of actions. This dialog inherits from [AcceptDialog], but has by default an OK and Cancel buton (in host OS order). Return the cancel button. Base node for containers. Base node for conainers. A [Container] contains other controls and automatically arranges them in a certain way. A Control can inherit this to reate custom container classes. Queue resort of the contained children. This is called automatically anyway, but can be called upon request. Fit a child control in a given rect. This is mainly a helper for creating custom container classes. Enmitted when sorting the children is needed. Notification for when sorting the children, it must be obeyed immediately. Control is the base node for all the GUI components. Control is the base class Node for all the GUI components. Every GUI component inherits from it, directly or indirectly. In this way, sections of the scene tree made of contiguous control nodes, become user interfaces. Controls are relative to the parent position and size by using anchors and margins. This ensures that they can adapt easily in most situation to changing dialog and screen sizes. When more flexibility is desired, [Container] derived nodes can be used. Anchors work by defining which margin do they follow, and a value relative to it. Allowed anchoring modes are ANCHOR_BEGIN, where the margin is relative to the top or left margins of the parent (in pixels), ANCHOR_END for the right and bottom margins of the parent and ANCHOR_RATIO, which is a ratio from 0 to 1 in the parent range. Input device events ([InputEvent]) are first sent to the root controls via the [method Node._input], which distribute it through the tree, then delivers them to the adequate one (under cursor or keyboard focus based) by calling [Node._input_event]. There is no need to enable input processing on controls to receive such events. To ensure that no one else will receive the event (not even [method Node._unhandled_input]), the control can accept it by calling [method accept_event]. Only one control can hold the keyboard focus (receiving keyboard events), for that the control must define the focus mode with [method set_focus_mode]. Focus is lost when another control gains it, or the current focus owner is hidden. It is sometimes desired for a control to ignore mouse/pointer events. This is often the case when placing other controls on top of a button, in such cases. Calling [method set_ignore_mouse] enables this function. Finally, controls are skinned according to a [Theme]. Setting a [Theme] on a control will propagate all the skinning down the tree. Optionally, skinning can be overrided per each control by calling the add_*_override functions, or from the editor. Called when an input event reaches the control. Return the minimum size this Control can shrink to. A control will never be displayed or resized smaller than its minimum size. Handles the event, no other control will receive it and it will not be sent to nodes waiting on [method Node._unhandled_input] or [method Node._unhandled_key_input]. Return the minimum size this Control can shrink to. A control will never be displayed or resized smaller than its minimum size. Return wether this control is a [i]window[/i]. Controls are considered windows when their parent [Node] is not a Control. Return the [i]window[/i] for this control, ascending the scene tree (see [method is_window]). Change the anchor (ANCHOR_BEGIN, ANCHOR_END, ANCHOR_RATIO) type for a margin (MARGIN_LEFT, MARGIN_TOP, MARGIN_RIGHT, MARGIN_BOTTOM). Changing the anchor mode converts the current margin offset from the previos anchor mode to the new one, so margin offsets ([method set_margin]) must be done after setting anchors, or at the same time ([method set_anchor_and_margin]). Return the anchor type (ANCHOR_BEGIN, ANCHOR_END, ANCHOR_RATIO) for a given margin (MARGIN_LEFT, MARGIN_TOP, MARGIN_RIGHT, MARGIN_BOTTOM). Set a margin offset. Margin can be one of (MARGIN_LEFT, MARGIN_TOP, MARGIN_RIGHT, MARGIN_BOTTOM). Offset value being set depends on the anchor mode.

Returns the size of the Control, computed from all margins, however the size returned will [b]never be smaller than the minimum size reported by [method get_minimum_size][/b]. This means that even if end position of the Control rectangle is smaller than the begin position, the Control will still display and interact correctly. (see description, [method get_minimum_size], [method set_margin], [method set_anchor]). Returns the Control position, relative to the top-left corner of the parent Control and independent of the anchor mode. Return position and size of the Control, relative to the top-left corner of the parent Control. This is a helper (see [method get_pos],[method get_size]). Return position and size of the Control, relative to the top-left corner of the [i]window[/i] Control. This is a helper (see [method get_global_pos],[method get_size]). Change all margins and anchors, so this Control always takes up the same area as the parent Control. This is a helper (see [method set_anchor],[method set_margin]). Display a Control as modal. Control must be a subwindow (see [method set_as_subwindow]). Modal controls capture the input signals until closed or the area outside them is accessed. When a modal control loses focus, or the ESC key is pressed, they automatically hide. Modal controls are used extensively for popup dialogs and menus. Set the focus access mode for the control (FOCUS_NONE, FOCUS_CLICK, FOCUS_ALL). Only one Control can be focused at the same time, and it will receive keyboard signals. Return wether the Control is the current focused control (see [method set_focus_mode]). Steal the focus from another control and become the focused control (see [method set_focus_mode]).

Special button that brings up a [PopupMenu] when clicked. Special button that brings up a [PopupMenu] when clicked. That's pretty much all it does, as it's just a helper class when bulding GUIs. Return the [PopupMenu] contained in this button. A [Resource] that contains vertex-array based geometry. Mesh is a type of [Resource] that contains vertex-array based geometry, divided in [i]surfaces[/i]. Each surface contains a completely separate array and a material used to draw it. Design wise, a mesh with multiple surfaces is prefered to a single surface, because objects created in 3D editing software commonly contain multiple materials. Create a new surface ([method get_surface_count] that will become surf_idx for this. Surfaces are created to be rendered using a "primitive", which may be PRIMITIVE_POINTS, PRIMITIVE_LINES, PRIMITIVE_LINE_STRIP, PRIMITIVE_LINE_LOOP, PRIMITIVE_TRIANGLES, PRIMITIVE_TRIANGLE_STRIP, PRIMITIVE_TRIANGLE_FAN. (As a note, when using indices, it is recommended to only use just points, lines or triangles). The format of a surface determines which arrays it will allocate and hold, so "format" is a combination of ARRAY_FORMAT_* mask constants ORed together. ARRAY_FORMAT_VERTEX must be always present. "array_len" determines the amount of vertices in the array (not primitives!). if ARRAY_FORMAT_INDEX is in the format mask, then it means that an index array will be allocated and "index_array_len" must be passed. Return the amount of surfaces that the [Mesh] holds. Remove a surface at position surf_idx, shifting greater surfaces one surf_idx slot down. Return the length in vertices of the vertex array in the requested surface (see [method add_surface]). Return the length in indices of the index array in the requested surface (see [method add_surface]). Return the format mask of the requested surface (see [method add_surface]). Return the primitive type of the requested surface (see [method add_surface]). Set a [Material] for a given surface. Surface will be rendered using this material. Return a [Material] in a given surface. Surface is rendered using this material. Default value used for index_array_len when no indices are present. Amount of weights/bone indices per vertex (always 4). Vertex array (array of [Vector3]() vertices). Normal array (array of [Vector3]() normals).

Render array as triangles (every three vertices a triangle is created). Render array as triangle strips. Render array as triangle fans. Node that instances meshes into a [Scenario]. MeshInstance is a [Node] that takes a [Mesh] resource and adds it to the current [Scenario] by creating an instance of it. This is the class most often used to get 3D geometry rendered and can be used to instance a sigle [Mesh] in many places. This allows to reuse geometry and save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance] instead. Set the [Mesh] resource for the instance. Return the current [Mesh] resource for the instance. Return the AABB of the mesh, in local coordinates. This helper creates a [StaticBody] child [Node] using the mesh geometry as collision. It's mainly used for testing. Library of meshes. Library of meshes. Contains a list of [Mesh] resources, each with name and ID. Useful for GridMap or painting Terrain. Create a new item in the library, supplied an id. Set the name of the item. Set the mesh of the item. Return the name of the item. Return the mesh of the item. Remove the item. Clear the library. Return the list of items. Get an unused id for a new item. Provides high perfomance mesh instancing. MultiMesh provides low level mesh instancing. If the amount of [Mesh] instances needed goes from hundreds to thousands (and most need to be visible at close proximity) creating such a large amount of [MeshInstance] nodes may affect performance by using too much CPU or video memory. For this case a MultiMesh becomes very useful, as it can draw thousands of instances with little API overhead.[br] As a drawback, if the instances are too far away of each other, performance may be reduced as every sigle instance will always rendered (they are spatially indexed as one, for the whole object). Since instances may have any behavior, the AABB used for visibility must be provided by the user, or generated with [method generate_aabb]. Set the [Mesh] resource to be drawn in multiple instances. Return the [Mesh] resource drawn as multiple instances. Set the amount of instnces that is going to be drawn. Changing this number will erase all the existing instance transform and color data. Return the amount of instnces that is going to be drawn. Set the transform for a specific instance. Return the transform of a specific instance. Set the color of a specific instance. Get the color of a specific instance. Set the visibility AABB. If not provided, MultiMesh will not be visible. Return the visibility AABB. Generate a new visibility AABB, using mesh AABB and instance transforms. Since instance information is stored in the [VisualServer], this function is VERY SLOW and must NOT be used often. Node that instances a [MultiMesh]. MultiMeshInstance is a [Node] that takes a [MultiMesh] resource and adds it to the current [Scenario] by creating an instance of it (yes, this is an instance of instances). Set the [MultiMesh] to be instance. Return the [MultiMesh] that is used for instancing. Base class for all the "Scene" elements. Nodes can be set as children of other nodes, resulting in a tree arrangement. Any tree of nodes is called a "Scene". Scenes can be saved to disk, and then instanced into other scenes. This allows for very high flexibility in the architecture and data model of the projects. [SceneMainLoop] contains the "active" tree of nodes, and a node becomes active (receinving NOTIFICATION_ENTER_SCENE) when added to that tree. A node can contain any number of nodes as a children (but there is only one tree root) with the requirement that no two childrens with the same name can exist. Nodes can, optionally, be added to groups. This makes it easy to reach a number of nodes from the code (for example an "enemies" group). Nodes can be set to "process" state, so they constantly receive a callback requesting them to process (do anything). Normal processing ([method _process]) happens as fast as possible and is dependent on the frame rate, so the processing time delta is variable. Fixed processing ([method _fixed_process]) happens a fixed amount of times per second (by default 60) and is useful to link itself to the physics. Nodes can also process input events. When set, the [method _input] function will be called with every input that the program receives. Since this is usually too overkill (unless used for simple projects), an [method _unhandled_input] function is called when the input was not handled by anyone else (usually, GUI [Control] nodes). To keep track of the scene hieararchy (specially when instancing scenes into scenes) an "owner" can be set to a node. This keeps track of who instanced what. This is mostly useful when writing editors and tools, though. Finally, when a node is freed, it will free all its children nodes too. Called for fixed processing (synced to the physics). Called when any input happens (also must enable with [method set_process_input] or the property). Called for processing. This is called every frame, with the delta time from the previous frame. Called when ready (entered scene and children entered too). Called when any input happens that was not handled by something else (also must enable with [method set_process_unhandled_input] or the property). Called when any key input happens that was not handled by something else. Set the name of the [Node]. Name must be unique within parent, and setting an already existing name will cause for the node to be automatically renamed. Return the name of the [Node]. Name is be unique within parent. Add a child [Node]. Nodes can have as many children as they want, but every child must have a unique name. Children nodes are automatically deleted when the parent node is deleted, so deleting a whole scene is performed by deleting its topmost node. Remove a child [Node]. Node is NOT deleted and will have to be deleted manually. Return the amount of children nodes. Return a children node by it's index (see [method get_child_count]). This method is often used for iterating all children of a node. Fetch a node. NodePath must be valid (or else error will occur) and can be either the path to child node, a relative path (from the current node to another node), or an absolute path to a node. Note: fetching absolute paths only works when the node is inside the scene tree (see [method is_inside_scene]). Examples. Assume your current node is Character and following tree:[br] root/ root/Character root/Character/Sword root/Character/Backpack/Dagger root/MyGame root/Swamp/Alligator root/Swamp/Mosquito root/Swamp/Goblin Possible paths are: - get_node("Sword") - get_node("Backpack/Dagger") - get_node("../Swamp/Alligator") - get_node("/root/MyGame") Return the parent [Node] of the current [Node], or an empty Object if the node lacks a parent. Return [i]true[/i] if the "node" argument is a direct or indirect child of the current node, otherwise return [i]false[/i]. Return [i]true[/i] if "node" occurs later in the scene hierarchy than the current node, otherwise return [i]false[/i]. Return the absolute path of the current node. This only works if the curent node is inside the scene tree (see [method is_inside_scene]). Return the relative path from the current node to the specified node in "node" argument. Both nodes must be in the same scene, or else the function will fail. Add a node to a group. Groups are helpers to name and organize group of nodes, like for example: "Enemies", "Collectables", etc. A [Node] can be in any number of groups. Nodes can be assigned a group at any time, but will not be added to it until they are inside the scene tree (see [method is_inside_scene]). Remove a node from a group. Move a child node to a different position (order) amongst the other children. Since calls, signals, etc are performed by tree order, changing the order of chilren nodes may be useful. Move this node to the top of the array of nodes of the parent node. This is often useful on GUIs ([Control]), because their order of drawing fully depends on their order in the tree. Set the node owner. A node can have any other node as owner (as long as a valid parent, grandparent, etc ascending in the tree). When saving a node (using SceneSaver) all the nodes it owns will be saved with it. This allows to create complex SceneTrees, with instancing and subinstancing. Get the node owner (see [method set_node_owner]). Remove a node and set all its children as childrens of the parent node (if exists). All even subscriptions that pass by the removed node will be unsubscribed. Get the node index in the parent (assuming it has a parent). Print the screne to stdout. Used mainly for debugging purposes. A node can contain a filename. This filename should not be changed by the user, unless writing editors and tools. When a scene is instanced from a file, it topmost node contains the filename from where it was loaded. Return a filename that may be containedA node can contained by the node. When a scene is instanced from a file, it topmost node contains the filename from where it was loaded (see [method set_filename]). Notify the current node and all its chldren recursively by calling notification() in all of them. Enables or disables node fixed framerate processing. When a node is being processed, it will receive a NOTIFICATION_PROCESS at a fixed (usually 60fps, check [OS] to change that) interval (and the [method _fixed_process] callback will be called if exists). It is common to check how much time was elapsed since the previous frame by calling [method get_fixed_process_time]. Return the time elapsed since the last fixed frame. This is always the same in fixed proecssing unless the frames per second is changed in [OS]. Return true if fixed processing is enabled (see [method set_fixed_process]). Enables or disables node processing. When a node is being processed, it will receive a NOTIFICATION_PROCESS on every drawn frame (and the [method _process] callback will be called if exists). It is common to check how much time was elapsed since the previous frame by calling [method get_process_time]. Return the time elapsed (in seconds) since the last process callback. This is almost always different each time. Return whether processing is enabled in the current node (see [method set_process]). Enable input processing for node. This is not requiered for GUI controls! It hooks up the node to receive all input (see [method _input]). Return true if the node is processing input (see [method set_process_input]). Enable unhandled input processing for node. This is not requiered for GUI controls! It hooks up the node to receive all input that was not previously handled before (usually by a [Control]). (see [method _unhandled_input]). Return true if the node is processing unhandled input (see [method set_process_unhandled_input]). Return true if the node can process. Return a duplicate of the scene, with all nodes and parameters copied. Subscriptions will not be duplicated. Replace a node in a scene by a given one. Subscriptions that pass through this node will be lost. Emitted when the node is renamed. Notification received every frame when the process flag is set (see [method set_process]). Notification received when a node is set as a child of another node. Note that this doesn't mean that a node entered the Scene Tree. Notification received when a node is unparented (parent removed it from the list of children). Base node for 2D system. Base node for 2D system. Node2D contains a position, rotation and scale, which is used to position and animate. It can alternatively be used with a custom 2D transform ([Matrix32]). A tree of Node2Ds allows complex hierachies for animation and positioning. Set the position of the 2d node. Set the rotation of the 2d node. Set the scale of the 2d node. Return the position of the 2D node. Return the rotation of the 2D node. Return the scale of the 2D node. Return the global position of the 2D node. Built-in type optimized for path traversing.

Return true if the engine was executed with -v (verbose stdout). Return the max amount of static memory used (only works in debug). Return the total amount of dynamic memory used (only works in debug). Base class for all non built-in types. Base class for all non built-in types. Everything not a built-in type starts the inheritance chain from this class. Objects do not manage memory, if inheriting from one the object will most likely have to be deleted manually (call the [method free] function from the script or delete from C++). Some derivates add memory management, such as [Reference] (which keps a reference count and deletes itself automatically when no longer referenced) and [Node], which deletes the children tree when deleted. Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in [method _get_property_list] and handled in [method _get] and [_set]. However, scripting languages and C++ have simper means to export them. Objects also receive notifications ([method _notification]). Notifications are a simple way to notify the object about simple events, so they can all be handled together. Return a property, return null if the property does not exist. Return the property list, array of dictionaries, dictionaries must countain: name:String, type:int (see TYPE_* enum in globals) and optionally: hint:int (see PROPERTY_HINT_* in globals), hint_string:String, usage:int (see PROPERTY_USAGE_* in globals).

Return the object script (or null if it doesn't have one). Set a metadata into the object. Medatada is serialized. Metadata can be [i]anything[/i]. Return a metadata from the object. Return true if a metadata is found with the requested name. Return the list of metadatas in the object. Add a user signal (can be added anytime). Arguments are optional, but can be added as an array of dictionaries, each containing "name" and "type" (from [@GlobalScope] TYPE_*). Emit a signal. Arguments are passed in an array. Call a function in the object, result is returned. Create and store a function in the object. The call will take place on idle time. Return the list of signals as an array of dictionaries. Connect a signal to a method at a target (member function). Binds are optional and are passed as extra arguments to the call. Flags specify optional deferred or one shot connections, see enum CONNECT_*. A signal can only be connected once to a method, and it will throw an error if already connected. If you want to avoid this, use [method is_connected] to check. Disconnect a signal from a method. Return true if a connection exists for a given signal and target/method. If set to true, signal emission is blocked. Return true if signal emission blocking is enabled. Set true if this object can translate strings (in calls to tr() ). Default is true. Return true if this object can translate strings. Deprecated, will go away. Translate a message. Only works in message translation is enabled (which is by default). See [method set_message_translation]. Called right when the object is initialized. Not available in script. Called before the object is about to be deleted. Connect a signal in deferred mode. This way, signal emissions are stored in a queue, then set on idle time. Persisting connections are saved when the object is serialized to file. One short connections disconnect themselves after emission. OmniDirectional Light, such as a lightbulb or a candle. An OmniDirectional light is a type of [Light] node that emits lights in all directions. The light is attenuated through the distance and this attenuation can be configured by changing the energy, radius and attenuation parameters of [Light]. TODO: Image of an omnilight. Button control that provides selectable options when pressed. OptionButton is a type button that provides a selectable list of items when pressed. The item selected becomes the "current" item and is displayed as the button text. Add an item, with text "label" and (optionally) id. If no "id" is passed, "id" becomes the item index. New items are appended at the end. Add an item, with a "texture" icon, text "label" and (optionally) id. If no "id" is passed, "id" becomes the item index. New items are appended at the end. Set the text of an item at index "idx". Set the icon of an item at index "idx". Set the ID of an item at index "idx". Return the text of the item at index "idx". Return the icon of the item at index "idx". Return the ID of the item at index "idx". Return the amount of items in the OptionButton. Add a separator to the list of items. Separators help to group items. Separator also takes up an index and is appended at the end. Clear all the items in the [OptionButton]. Select an item by index and make it the current item. Return the current item index This signal is emitted when the current item was changed by the user. ID of the item selected is passed as argument (if no IDs were added, ID will be just the item index). Optimized translation. Optimized translation. Uses real-time compressed translations, which results in very small dictionaries. TODO: explain ownership, and that node does not need to own itself Pack will ignore any sub-nodes not owned by given node. See [Node.set_owner]. Abstraction and base class for packet-based protocols. PacketPeer is an abstration and base class for packet-based protocols (such as UDP). It provides an API for sending and receiving packets both as raw data or variables. This makes it easy to transfer data over a protocol, without having to encode data as low level bytes or having to worry about network ordering. Wrapper to use a PacketPeer over a StreamPeer. PacketStreamPeer provides a wrapper for working using packets over a stream. This allows for using packet based code with StreamPeers. PacketPeerStream implements a custom protocol over the StreamPeer, so the user should not read or write to the wrapped StreamPeer directly. Set the StreamPeer object to be wrapped Provides an opaque background for [Control] children. Panel is a [Control] that displays an opaque background. It's commoly used as a parent and container for other types of [Control] nodes. [center][img]images/panel_example.png[/img][/center] Panel container type. Panel container type.

Portals provide virtual openings to [RoomInstance] nodes, so cameras can look at them from the outside. Note that portals are a visibility optimization technique, and are in no way related to the game of the same name (as in, they are not used for teleportation). For more information on how rooms and portals work, see [RoomInstance]. Portals are represented as 2D convex polygon shapes (in the X,Y local plane), and are placed on the surface of the areas occupied by a [RoomInstance], to indicate that the room can be accessed or looked-at through them. If two rooms are next to each other, and two similar portals in each of them share the same world position (and are parallel and opposed to each other), they will automatically "connect" and form "doors" (for example, the portals that connect a kitchen to a living room are placed in the door they share). Portals must always have a [RoomInstance] node as a parent, grandparent or far parent, or else they will not be active. Set the portal shape. The shape is an array of [Point2] points, representing a convex polygon in the X,Y plane. Return the portal shape. The shape is an array of [Point2] points, representing a convex polygon in the X,Y plane. Enable the portal (it is enabled by defaul though), disabling it will cause the parent [RoomInstance] to not be visible any longer when looking through the portal. Return wether the portal is active. When disabled it causes the parent [RoomInstance] to not be visible any longer when looking through the portal. Set the distance threshold for disabling the portal. Every time that the portal goes beyond "distance", it disables itself, becoming the opaque color (see [method set_disabled_color]). Return the distance threshold for disabling the portal. Every time that the portal goes beyond "distance", it disables itself, becoming the opaque color (see [method set_disabled_color]). When the portal goes beyond the disable distance (see [method set_disable_distance]), it becomes opaque and displayed with color "color". Return the color for when the portal goes beyond the disable distance (see [method set_disable_distance]) and becomes disabled. Set the range for auto-connecting two portals from different rooms sharing the same space. Return the range for auto-connecting two portals from different rooms sharing the same space.

It's just like an empty control, except a red box is displayed while editing around it's size at all times. Base class for all resources. Resource is the base class for all resource types. Resources are primarily data containers. They are reference counted and freed when no longer in use. They are also loaded only once from disk, and further attempts to load the resource will return the same reference (all this in contrast to a [Node], which is not reference counted and can be instanced from disk as many times as desred). Resources can be saved externally on disk or bundled into another object, such as a [Node] or another resource. Set the path of the resource. This is useful mainly for editors when saving/loading, and shouldn't be changed by anything else. Return the path of the resource.

This node is used for placing rigid bodies in the scene. It can contain a number of shapes, and also shift state between regular Rigid Body to Character or even Static. Character mode forbids the node from being rotated. This node can have a custom force integrator function, for writing complex physics motion behavior per node. As a warning, don't change this node position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop will yield strange behavior. Override this function to use a custom force integrator. This allows to hook up to the physics processing and alter the simulation state for the object on every frame.

Button that can be themed with textures. Button that can be themed with textures. This is like a regular [Button] but can be themed by assigning textures to it. This button is intended to be easy to theme, however a regular button can expand (that uses styleboxes) and still be better if the interface is expect to have internationalization of texts. Only the normal texture is required, the others are optional. Control Frame that draws a texture. Control frame that simply draws an assigned texture. It can stretch or not. It's a simple way to just show an image in a UI. Textured progress bar implementation. [ProgressBar] implementation that is easier to theme (by just passing a few textures). Theme for controls. Theme for skinning controls. Controls can be skinned individually, but for complex applications it's more efficient to just create a global theme that defines everything. This theme can be applied to any [Control], and it and its children will automatically use it. Theme resources can be alternatively loaded by writing them in a .theme file, see wiki for more info. Node for 2D Tile-Based games. Node for 2D Tile-Based games. Tilemaps use a TileSet which contain a list of tiles (textures, their rect and a collision) and are used to create complex grid-based maps.

A Viewport creates a different view into the screen, or a sub-view inside another viewport. Children 2D Nodes will display on it, and children Camera 3D nodes will render on it too. Optionally, a viewport can have its own 2D or 3D world, so they don't share what they draw with other viewports. If a viewport is a child of a [Control], it will automatically take up its same rect and position, otherwise they must be set manually. Viewports can also choose to be audio listeners, so they generate positional audio depending on a 2D or 3D camera child of it. Also, viewports can be assigned to different screens in case the devices have multiple screens. Finally, viewports can also behave as render targets, in which case they will not be visible unless the associated texture is used to draw. Set the viewport rect. If the viewport is child of a control, it will use the same rect as the parent. Return the viewport rect. If the viewport is child of a control, it will use the same rect as the parent. Otherwise, if the rect is empty, the viewport will use all the allowed space. Return the final, visuble rect in global screen coordinates. If this viewport is a child of another viewport, keep the previously drawn background visible. Reurn whether the viewport lets whatever is behind it to show. Get the viewport RID from the visual server. Server for anything visible. Server for anything visible. The visual server is the API backend for everything visible.
