Godot: [TRACKER] Collision Shape issues for 3.0

[nunodonato]

This issue tracks improvements, bugs and compatibility breaks related with Collision Shapes and Godot 3.x

• [x] Rigidbodies in linked scenes use linked collision shapes, even if the collision shape is changed in the parent scene #9105
• [x] CollisionShapes cannot be rotated #8153
• [x] Collision shapes overridden in inherited scenes are not used by physics, but display fine. #8103
• [x] Godot 3.0 Collisions Shapes (CollisionShape2D / CollisionPolygon2D) dont get drawn on the editor or debug, except RectangleShape2D, RayShape2D or LineShape2D #8033
• [x] Shape2D added to CollisionObject2D do not appear with Visual Collision enabled. #7281
• [x] Collision shapes are drawn in wrong color and collision contact points are not drawn at all #8607
• [x] Add one-way collision to tile-set/tile-map (2.1) #8558
• [x] Collision shape gizmo isn't updated upon changing the shape #8910
• [x] User imported 3D Collision Shapes only interact with primitives and not each other #4591
• [x] Physic Body Instanced scene doesn't use CollisionShapes #2314
• [x] CollisionShape2D does not exist at run-time after reparent/duplication #1183
• [x] Trimesh Static bodies generated incorrectly #3947
• [x] Poor optimizations in the physics engine #7690
• [x] Instanced CollisionPolygon2D's cannot perform collision detection #8896
• [ ] Error 3D physics, violation collision mesh RigidBody and other body #4831
• [ ] Collision with edges between convex/planar face pair #7701
• [x] Collision shapes persist after they've been deleted #7693
• [x] Buggy collision detection when ConvexPolygonShape2D is given a concave polygon with set_points() #8611
• [x] Convex collision shapes + kinematic body + look_at + move = cpu catches fire #8750 (unconfirmed)
• [ ] Bad collision against StaticBody2D with LineShape2D #7920
• [ ] CollisionShape2D trigger doesn't behave as expected #4393
• [ ] "Create convex static body/collision sibling" freezes the editor if used on sphere mesh #21141

Improvements / Suggestions

• [x] Scaled RigidBody should show a node warning in the scene tree as it's something that should not be done #7615
• [ ] "Collision Groups" handling Collision Layers & Masks #7793
• [ ] Expose collision resolution bias in editor for rigid bodies/collision shapes #7700
• [x] Attaching CollisionShapes to bones #8318
• [ ] Shape Colision Editor Suggestions #8227

This affects 3 too #7920

@eon-s added in, thanks!

[Einlander]

Does godot 3 still ignore scaled collision shapes?

@DimitriyPS added, thanks!

[eon-s]

Tested #7644 , affects 3 too.

@eon-s, @akien-mga asked to keep this tracker focused specifically on CollisionShapes and not collisions in general, so I guess that one doesn't qualify :)

9105, #8153, #8103, #7281, #8607, #8558, #8910, #4591, #2314, and #1183 are all fixed/closed. (This list is in the same order as they're listed in the tracker.)

[Einlander]

There is also this one. https://github.com/godotengine/godot/issues/3947

Another collision shape bug #13835

[LinuxUserGD]

12521 (after resizing the collision shape)

[LinuxUserGD]

4831 is Godot 2.1.3

[Chaosus]

Added #21141

[williamd1k0]

I just found this one #14599

[eon-s]

This may need to be closed and make a new one for 3.1 and 3.2/4.0

[Chaosus]

I recreated this list here (for better visibility) - #24816 - all fixed issues are removed + re-targeted to 3.2
