<description>
The ARVR Anchor point is a spatial node that maps a real world location identified by the AR platform to a position within the game world. For example, as long as plane detection in ARKit is on, ARKit will identify and update the position of planes (tables, floors, etc) and create anchors for them.
This node is mapped to one of the anchors through its unique id. When you receive a signal that a new anchor is available, you should add this node to your scene for that anchor. You can predefine nodes and set the id and the nodes will simply remain on 0,0,0 until a plane is recognised.

Keep in mind that, as long as plane detection is enabled, the size, placing and orientation of an anchor will be updated as the detection logic learns more about the real world out there especially if only part of the surface is in view.

<brief_description>
Main loop is the abstract main loop base class.
Abstract base class for the game's main loop.
</brief_description>
<description>
Main loop is the abstract main loop base class. All other main loop classes are derived from it. Upon application start, a [MainLoop] has to be provided to OS, else the application will exit. This happens automatically (and a [SceneTree] is created), unless a main [Script] is supplied, which may or not create and return a [MainLoop].
[MainLoop] is the abstract base class for a Godot project's game loop. It in inherited by [SceneTree], which is the default game loop implementation used in Godot projects, though it is also possible to write and use one's own [MainLoop] subclass instead of the scene tree.
Upon application start, a [MainLoop] implementation has to be provided to the OS, or the application will exit. This happens automatically (and a [SceneTree] is created) unless a main [Script] is provided from the command line (with e.g. [code]godot -s my_loop.gd[/code], which should then be a [MainLoop] implementation.
Here is an example script implementing a simple [MainLoop]:
[codeblock]
extends MainLoop
var time_elapsed = 0
var keys_typed = []
var quit = false
func _initialize():
print("Initialized:")
print(" Starting time: %s" % str(time_elapsed))
func _idle(delta):
time_elapsed += delta
# Return true to end the main loop
return quit
func _input_event(event):
# Record keys
if event is InputEventKey and event.pressed and !event.echo:
keys_typed.append(OS.get_scancode_string(event.scancode))
# Quit on Escape press
if event.scancode == KEY_ESCAPE:
quit = true
# Quit on any mouse click
if event is InputEventMouseButton:
quit = true
func _finalize():
print("Finalized:")
print(" End time: %s" % str(time_elapsed))
print(" Keys typed: %s" % var2str(keys_typed))
[/codeblock]

<description>
Nodes are Godot's building blocks. They can be assigned as the child of another node, resulting in a tree arrangement. A given node can contain any number of nodes as children with the requirement that all siblings (direct children of a node) should have unique names.
A tree of nodes is called a [i]scene[/i]. Scenes can be saved to the disk and then instanced into other scenes. This allows for very high flexibility in the architecture and data model of Godot projects.
[b]Scene tree:[/b] The [SceneTree] contains the active tree of nodes. When a node is added to the scene tree, it receives the NOTIFICATION_ENTER_TREE notification and its [method _enter_tree] callback is triggered. Child nodes are always added [i]after[/i] their parent node, i.e. the [method _enter_tree] callback of a parent node will be triggered before its child's.
Once all nodes have been added in the scene tree, they receive the NOTIFICATION_READY notification and their respective [method _ready] callbacks are triggered. For groups of nodes, the [method _ready] callback is called in reverse order, starting with the children and moving up to the parent nodes.
[b]Scene tree:[/b] The [SceneTree] contains the active tree of nodes. When a node is added to the scene tree, it receives the [constant NOTIFICATION_ENTER_TREE] notification and its [method _enter_tree] callback is triggered. Child nodes are always added [i]after[/i] their parent node, i.e. the [method _enter_tree] callback of a parent node will be triggered before its child's.
Once all nodes have been added in the scene tree, they receive the [constant NOTIFICATION_READY] notification and their respective [method _ready] callbacks are triggered. For groups of nodes, the [method _ready] callback is called in reverse order, starting with the children and moving up to the parent nodes.
This means that when adding a node to the scene tree, the following order will be used for the callbacks: [method _enter_tree] of the parent, [method _enter_tree] of the children, [method _ready] of the children and finally [method _ready] of the parent (recursively for the entire scene tree).
[b]Processing:[/b] Nodes can override the "process" state, so that they receive a callback on each frame requesting them to process (do something). Normal processing (callback [method _process], toggled with [method set_process]) happens as fast as possible and is dependent on the frame rate, so the processing time [i]delta[/i] is passed as an argument. Physics processing (callback [method _physics_process], toggled with [method set_physics_process]) happens a fixed number of times per second (60 by default) and is useful for code related to the physics engine.
Nodes can also process input events. When present, the [method _input] function will be called for each input that the program receives. In many cases, this can be overkill (unless used for simple projects), and the [method _unhandled_input] function might be preferred; it is called when the input event was not handled by anyone else (typically, GUI [Control] nodes), ensuring that the node only receives the events that were meant for it.

This method has slightly different behavior based on whether the [code]blocking[/code] mode is enabled.
When [code]blocking[/code] is enabled, the Godot thread will pause its execution while waiting for the process to terminate. The shell output of the process will be written to the [code]output[/code] array as a single string. When the process terminates, the Godot thread will resume execution.
When [code]blocking[/code] is disabled, the Godot thread will continue while the new process runs. It is not possible to retrieve the shell output in non-blocking mode, so [code]output[/code] will be empty.
The return value also depends on the blocking mode. When blocking, the method will return -2 (no process ID information is available in blocking mode). When non-blocking, the method returns a process ID, which you can use to monitor the process (and potentially terminate it with [method kill]). If the process forking (non-blocking) or opening (blocking) fails, the method will return -1.

Objects do not manage memory. If a class inherits from Object, you will have to delete instances of it manually. To do so, call the [method free] method from your script or delete the instance from C++.
Some classes that extend Object add memory management. This is the case of [Reference], which counts references and deletes itself automatically when no longer referenced. [Node], another fundamental type, deletes all its children when freed from memory.
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 [method _set]. However, scripting languages and C++ have simpler means to export them.
Objects also receive notifications. Notifications are a simple way to notify the object about simple events, so they can all be handled together. See [method _notification].

SceneTree manages a hierarchy of nodes.
Manages the game loop via a hierarchy of nodes.
</brief_description>
<description>
As one of the most important classes, the [SceneTree] manages the hierarchy of nodes in a scene as well as scenes themselves. Nodes can be added, retrieved and removed. The whole scene tree (and thus the current scene) can be paused. Scenes can be loaded, switched and reloaded. You can also use the SceneTree to organize your nodes into groups: every node can be assigned as many groups as you want to create, e.g. a "enemy" group. You can then iterate these groups or even call methods and set properties on all the group's members at once.

This nodes implements all the physics logic needed to simulate a car. It is based on the raycast vehicle system commonly found in physics engines. You will need to add a [CollisionShape] for the main body of your vehicle and add [VehicleWheel] nodes for the wheels. You should also add a [MeshInstance] to this node for the 3D model of your car but this model should not include meshes for the wheels. You should control the vehicle by using the [member brake], [member engine_force], and [member steering] properties and not change the position or orientation of this node directly.
