- Use `NOTIFICATION_ENTER`/`EXIT_WORLD` for `Area` (intead of `*_TREE`).
- Now both bodies' and areas' constraints are cleaned up.
- And now also that happens as soon as the space is set to null (i.e., when exiting the tree) instead of only at freeing time.
- When clearing constraints, the loop goes on to the next if the current is already released, instead of breaking.
- When one has been already released, no error is shown from now on, as it's something expected, since a pair (our kind of constraint of interest) can be freed by any of its involved collision objects and the other will try again.
- Implement index shifting (or marking as -1) for shapes indices in collision pairs shapes are removed.
- Standarize behavior of bodies and areas so that anything that invalidates a given pair gives the same result (collision mask, actual collision, etc); for instance, triggering area enter/exit signals.
- Add missing member initializations.
- Extend the new-space-equals-area/body-current-space test to every case.
- Fix 3D ray-casts early accepting Areas (skipping the mask check).
- Fix unpairing of large elements (2D's `BroadPhase2DHashGrid`).
Some of these prevent random crashes caused by constraints with dangling pointers to involved objects.
Fixes#8856.
Fixes#7589.
Fixes#6676.
And maybe others.
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!
(cherry picked from commit c7bc44d5ad)
-IMA-ADPCM support for samples, this means that sound effects can be compressed and use 4 timess less RAM.
-New 3D import workflow based on Wavefront OBJ. Import single objects as mesh resources instead of full scenes. Many people prefers to work this way. Just like the rest of the imported resources, these are updated in realtime if modified externally.
-Mesh resources now support naming surfaces. This helps reimporting to identify which user-created materials must be kept.
-Several fixes and improvements to SurfaceTool.
-Anti Aliasing added to WorldEnvironment effects (using FXAA)
-2D Physics bodies (RigidBody, KinematicBody, etc), Raycasts, Tilemap, etc support collision layers. This makes easy to group which objects collide against which.
-2D Trigger shapes can now also trigger collision reporting in other 2D bodies (it used to be in Area2D before)
-Viewport render target textures can now be filtered.
-Few fixes in GDscript make it easier to work with static functions and class members.
-Several and many bugfixes.
