Question by pfg · Apr 14, 2018 at 11:25 PM · physicsrigidbodyrigidbody.addforce

Link two rigidbodies

I have two rigidbodies, one cube and one is the player. If the cube is pushed towards the ground, I want the character to go up. How can I do this?

I've tried using OnCollisionStay on the cube to push the player up characterBody.AddForce(collision.relativeVelocity * -1);

but this doesn't work very well and barely moves the player

Adding the following code snippet into the component on the player could work:

     Rigidbody rb;
     public Rigidbody linkedRB;
     void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
     void FixedUpdate()
     {
         rb.velocity = new Vector3(rb.velocity.x, -linkedRB.velocity.y, rb.velocity.z);
     }

This didn't work because the cube moves with the player

Can you try elaborating on exactly what you are trying to do?

e.g. Do you want the player to have full control and the box going down to boost the player's movement up? Or does the player only go up when the box goes down? Which direction is "up" in your scenario (x, y, or z)?

Is this trampoline situation? or an elevator where the cube is the counterweight? It's unclear what the purpose or circumstance of the collision is.
