I made a sidescroller and chose 3D since I don’t like the tilemap system and 2D art but in 3D i have a strange glitch which appears very rarely but it still happens sometimes. By jumping on a platform (Static Body) may player (Kinematic Body) falls through every single platform. As said, it happens rarely but still.

And here a proof that I’m not crazy, at the end of the video:

Just me being an idiot. The collision made my player move on the z axis, slightly but enough. velocity.z = 0 is enough to prevent this.
