Since this avoids accidentally placing 2D nodes at subpixel positions,
this results in more crisp visuals by default, even when pixel snapping
is disabled in the project settings.
* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions.
* Everything else converted to GDVIRTUAL
* BIND_VMETHOD is gone, always use the new syntax from now on.
Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
Adds support for dragging in all files of type Texture2D for 2D.
Adds support for dragging in all files of type Mesh for 3D.
Replaces adding texture as Light2D with PointLight2D.
Add more node types that textures can be added as
- TextureButton
- CPUParticles2D
Having a property which has the same name as its class leads to confusing
situations (e.g. `BaseButton` has a `shortcut` property of type `Shortcut`
which has a `shortcut` property of type `InputEvent`).
Also renames `is_event` to `matches_event`, and `is_valid` to `has_valid_event`
to better reflect what the methods check.
When dragging and dropping a texture, mesh, or scene from the FileSystem into the
2D or 3D viewport, it will be added as a child of the current scene's root node.
- Use the ° symbol instead of "deg" to reduce clutter.
- Round the displayed lengths to only one decimal instead of two
to further reduce clutter.
- Don't make the `px` suffix localizable, as it isn't localizable
anywhere else in the editor.
This makes it easier to notice that some menu items only appear when
specific nodes are selected.
This change applies to both 2D and 3D editors, including both plugin-based
menus and the hardcoded 2D layout/animation contextual menus.
- Makes tips clearer and more consistent.
- Removes outdated "shift+v" that doesn't work
- Adds Ctrl+RMB for adding nodes at position
- Removes tip for non-existent Alt+Drag in 3D select tool
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
- Use a smaller drag threshold (8 pixels instead of 10 pixels).
- Scale the 2D editor drag threshold with the zoom to make it
work the same regardless of the current zoom level.
- Add 1-5 shortcuts to zoom between 100% and 1600% quickly
(similar to GIMP).
- When holding down Alt, go through integer zoom values if above 100%
or fractional zoom values with integer denominators if below 100%
(50%, ~33.3%, 25%, …).
- Locking nodes can now be done by pressing Ctrl + L, and unlocking with
Ctrl + Shift + L.
- Grouping nodes is now done by pressing Ctrl + G, and ungrouping with
Ctrl + Shift + G (similar to Inkscape).
- Toggling the grid is now done by pressing the `#` key
(also similar to Inkscape). This change was needed as Ctrl + G
now groups selected nodes.
Different shortcuts are used for the lock/unlock and group/ungroup
actions, so that the shortcuts are idempotent.
* Functions to convert to/from degrees are all gone. Conversion is done by the editor.
* Use PROPERTY_HINT_ANGLE instead of PROPERTY_HINT_RANGE to edit radian angles in degrees.
* Added possibility to add suffixes to range properties, use "min,max[,step][,suffix:<something>]" example "0,100,1,suffix:m"
* In general, can add suffixes for EditorSpinSlider
Not covered by this PR, will have to be addressed by future ones:
* Ability to switch radians/degrees in the inspector for angle properties (if actually wanted).
* Animations previously made will most likely break, need to add a way to make old ones compatible.
* Only added a "px" suffix to 2D position and a "m" one to 3D position, someone needs to go through the rest of the engine and add all remaining suffixes.
* Likely also need to track down usage of EditorSpinSlider outside properties to add suffixes to it too.
This PR and commit adds a new IK system for 2D with the Skeleton2D node
that adds several new IK solvers, a way to control bones in a Skeleton2D
node similar to that in Skeleton3D. It also adds additional changes
and functionality.
This work was sponsored by GSoC 2020 and TwistedTwigleg.
Full list of changes:
* Adds a SkeletonModifier2D resource
* This resource is the base where all IK code is written and executed
* Has a function for clamping angles, since it is so commonly used
* Modifiers are unique when duplicated so it works with instancing
* Adds a SkeletonModifierStack2D resource
* This resource manages a series of SkeletonModification2Ds
* This is what the Skeleton2D directly interfaces with to make IK possible
* Adds SkeletonModifier2D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in its own file
* There is also a SkeletonModifier2D resource that acts as a stack for using multiple stacks together
* Adds a PhysicalBone2D node
* Works similar to the PhysicalBone3D node, but uses a RigidBody2D node
* Changes to Skeleton2D listed below:
* Skeleton2D now holds a single SkeletonModificationStack2D for IK
* Skeleton2D now has a local_pose_override, which overrides the Bone2D position similar to how the overrides work in Skeleton3D
* Changes to Bone2D listed below:
* The default_length property has been changed to length. Length is the length of the bone to its child bone node
* New bone_angle property, which is the angle the bone has to its first child bone node
* Bone2D caches its transform when not modified by IK for IK interpolation purposes
* Bone2D draws its own editor gizmo, though this is stated to change in the future
* Changes to CanvasItemEditor listed below:
* Bone2D gizmo drawing code removed
* The 2D IK code is removed. Now Bone2D is the only bone system for 2D
* Transform2D now has a looking_at function for rotating to face a position
* Two new node notifications: NOTIFICATION_EDITOR_PRE_SAVE and NOTIFICATION_EDITOR_POST_SAVE
* These notifications only are called in the editor right before and after saving a scene
* Needed for not saving the IK position when executing IK in the editor
* Documentation for all the changes listed above.
