The kinematic body (bot) is sinking into the ground

Tudor

Hello! In my game, I have started to develop a bot. Before it starts to move, it sinks into the ground to a quarter, even if it is a kinematic body with a collision shape, and walks on the ground that also has a collision shape. How could I fix this?

What is the collision shape of your kinematic body? What size is it (this is very important, smaller ones are bad)? And what about your ground, what shape is it? Post a picture or video of it, it will be easier to help.

You can turn on visible collision shapes in the debug menu on the top, that might help you see where the problem is.

In fact, I solved this problem by chance. Initially, I set the dimensions of the kinematic body, by scaling it. But, in order to have a more appropriate shape, I used another way to set the dimensions of the kinematic body: I set the height and radius of the mesh instance and collision shape. Surprisingly, this maneuver solved the problem. Now, the kinematic body no longer sinks in the ground. Thank you anyway!

Right, you can't scale collision shapes. You have to use the circles and do it manually.

Regarding the collision shape of the kinematic body, it is a capsule of 2 m height and 0.6 m radius. The ground is a spatial body with a shape of a rectangular parallelepiped.

Below are two images with the same kinematic body, but with the dimensions set in those two different ways: In the first one is represented the kinematic body scaled. In the second one, the radius and the height of the mesh instance and collision shape are set manually.

The idea with Visible Collision Shapes is great for future troubleshooting. Thanks!
