NPC walks through wall

Hello!

I’ve set up a character as an NPC.
This NCP has a rigidbody and a box collider.
The NPC chases the player.

The NPC’s position is simply driven by the root motion of the animation.
The rotation is done automatically by a script so that the NPC rotates towards the player.

I’ve placed a wall (a simple box) in front of the NPC.
The box has a box collider, and it’s set to “Static”.

I expected that the box collider of the wall would stop my NPC from walking through it, but it doesn’t.

But the wall does stop my FPS, so I think the problem must be within my NPC.

Does anybody know what I’m doing wrong?

Thank you for any hint.

I found the solution myself, it seems that I did forget to add the RigidBody to the NPC although I thought it had one on it already.
