Question by khryus · Jun 07, 2018 at 08:11 PM · movementphysicsconstant

How can I make a rigidbody stop with the user input and ignore its kinetic energy?

My goal is to move the character (currently a capsule) at constant/fixed speed in the direction the player wants to. When the player stops giving inputs, the character should instantly stop moving, however it currently keeps "sliding away" when I drop inputs because it has gained kinetic energy. How can I make it ignore that energy and stop it right away?


Controller script:

     // the player willingly moves and rotates according to camera rotation 
     // I have also set constraints on the X and Z rotation values on the rigidbody component
     // t$$anonymous$$s is a t$$anonymous$$rd person view game
     private void FixedUpdate()
     {
         rotate();
         Vector3 vert = getAxis("Vertical") * cameraTransform.forward;
         Vector3 horz = getAxis("Horizontal") * cameraTransform.right;
         rb.AddForce((vert + horz).normalized * speed, ForceMode.Impulse);
     }
 
     // todo: look towards the movement vector, reset to camera fwd when there is no movement
     void rotate()
     {
         Vector3 lookpos = transform.position + cameraTransform.forward;
         lookpos.y = transform.position.y;
         transform.LookAt(lookpos);
     }

     int getAxis(string name)
     {
         return Input.GetAxisRaw(name) > 0 ? 1 : Input.GetAxisRaw(name) < 0 ? -1 : 0;
     }

Properties of the character's rigidbody:

I have also attached a Physics Material to the character's Capsule Collider:
