This issue can only be reproduced with flat objects, if object is not flat, the character will not be able to step on the object immediately after knocking it over.

As the titled describes, if you knock over a flat object and immediately step over it, it sinks into the ground. Potential search direction is how Unity handles collision with the ground (of the type Mesh Collider, Pro Builder Mesh).

CharacterController does not offer any method to detect collision when staying still. The only collision detection function used by CC is OnControllerColliderHit, which is only called when a collision happens while CC is moving.

I spent a lot of time searching online for solving this problem, but it seems there is no clean way to do it. Potential solutions include:
a) keep the CC moving by small amount in each Update;
b) write code for collision detection in Update;
c) write your own character controller system using RigidBody [does not apply to this project]

I will add a couple links to the issue later that discusses solution for this issue.

Tried to use Physics(i.e. RigidBody) to simulate an knocked-away effect, but Rigidbody is hard to tune so the effect does not look very satisfying.
