CircleShape2D weird behavior with Moving Platforms

[henriiquecampos]

Godot version:

3.2.2.stable.official

OS/device including version:

Solus 4.1 Gnome 3.36.3

Issue description:

Using a CollisonShape2D with a CircleShape2D causes KinematicBody2D to behave weirdly when dealing with moving platforms. Check the minimal reproduction project for implementation details.

Bugs noticed:

• When the platform moves up the Player can't jump
  

• If CollisionShape2D.one_way_collision = true the above bug is fixed but the KinematicBody2D some times passes through the platform
  

Both problems are fixed when using a RectangleShape2D

Steps to reproduce:

1. Implement basic movement using KinematicBody2D.move_and_slide_with_snap()
2. Implement moving platforms with KinematicBody2D.sync_to_physics = true and an AnimationPlayer, optionally set the AnimationPlayer.playback_process_mode = ANIMATION_PROCESS_PHYSICS
3. Use CircleShape2D on the Player's KinematiBody2D/CollisionShape2D.shape
4. Animate the Platform moving up and down
5. Jump on the platform and try to jump on it when it goes up
6. Set the Platform's KinematicBody2D/CollisionShape2D.one_way_collision = true
7. Repeat step 5 with quick hops

Perhaps could be fixed by #36280?

Maybe the second issue, but I can't see how it would fix the first one, the one that prevents jumping when the platform moves up.

Both issues are fixed by #42574, closing.

Just tested Godot 3.3.stable.official, and they are not fixed.

Indeed, I can confirm this is still not fixed.

If CollisionShape2D.one_way_collision = true the above bug is fixed but the KinematicBody2D some times passes through the platform

This one seems to be fixed though. Are you still able to reproduce it?
