Questions & Answers
1

I want to move the cube using WASD and added rigidbody. But when I increase the moving speed bigger than 0.2f the cube does not collide with wall.

Please review my upload video to understand easily.

Try to use

 GetComponent<RigidBody>().MovePosition();

instead and change the rigidbody collision detection setting from discrete to continuous.
