Some of those are bugs and need further work, they are identified with
`// FIXME` comments.
Better heuristic for the shortest path algorithm for navigation2D and navigation.
It now will use the shortest distance to the polygon as cost instead of the distance to the center.
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
It's shared by both 2D and 3D particles (+ CPU ones), so it makes sense
to have as a common resource. It also allowed to disable compilation of
Particles (3D) when using 'disable_3d'.
Also cleaned up includes in SpatialEditorGizmos and some other places,
as well as dropped dead code in material_editor_plugin.cpp.
Without this change any new PhysicsBody would show deprecation warnings
due to default values for friction and bounce being defined.
It also enforced a physics material override even when using default
values.
New APIs in 2D physics allow intersection queries filtered by CanvasLayer object instance id. Viewport keep an inventory of its descendant CanvasLayers and takes advantage of all that to test picking with the mouse/touch position correctly transformed for each CanvasLayer.
This average is not a proper approximation of a grayscale value,
get_v() is better suited for that.
If we want a real to_grayscale() conversion, it's somewhat more
involved: https://en.wikipedia.org/wiki/Grayscale
Remove the deprecated Gray() from C# bindings as it conflicts
with new named color constants.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
This fixes the situation where a `CanvasItem` descendant of a `Viewport` which in turn is a descendant of a `CanvasLayer` prefers the more outer `CanvasLayer` rather than the `Vierport`'s.
Because of that, `CanvasItem`s inside a `Viewport` inside a `CanvasLayer` were being rendered to the main `Viewport` instead of the render target of the innermost one.
This reverts commit 4d277b96ad.
Woops, this wasn't meant to be committed. I just reverted it locally
to test something, nothing wrong with the original commit :)
It appears that some time ago users were supposed to be able to include the playback of sound effects in their animations by placing keys on the "playing" property. Back then the key frame editor took the value of the checkbox in the property_editor.
Somewhere / Sometime this behaviour changed and the key frame editor is now reading the actual value from the object instead of relying on the property editor.
This commit introduces a fake active field that is returned when reading the playing property in the editor. While the actual active flag is changed when playback is finished the fake one will stay the same thus allowing the user to take their time with setting the key in the animation editor.
Make TileMap monitor its TileSet for changes and emit a signal when the TileSet changes. This makes the editor update and show the updated version of the TileSet.
