Question by erickrmz · Feb 22, 2012 at 10:00 PM · collisioncollidercubepushcrate

Newbie: How to "push" a cube using mode FPS

Hello, first of all im really really new...

I download the 2DGamePlayTutorial and im notice that the "boxes" or crates can be pushed if the characters collision with them.

Now i make my own "game" or just im using a FPScontroller, i create a cube with collider and rigidbody, but when i collision with the cube does not move is like solid and attached to the ground (my ground or floor is another cube). I want to walk and when i collision the cube, this can be pushed and fall...

I try to import the crate from the 2DGamePlayTutorial and it does not work

Any suggest?? thanks in advance

Erick

I did it myself:

  1. Create a Javascript file on Project window i called "Push.js"

  2. COpy the code from script documentation, this is the script:

    // this script pushes all rigidbodies that the character touches var pushPower = 2.0;

    function OnControllerColliderHit (hit : ControllerColliderHit) { var body : Rigidbody = hit.collider.attachedRigidbody;

      // no rigidbody
         if (body == null || body.isKinematic) { return; }
     
         // We dont want to push objects below us
         if (hit.moveDirection.y < -0.3) { return; }
     
         // Calculate push direction from move direction,
         // we only push objects to the sides never up and down
         var pushDir = Vector3 (hit.moveDirection.x, 0, hit.moveDirection.z);
     
         // If you know how fast your character is trying to move,
         // then you can also multiply the push velocity by that.
     
         // Apply the push
         body.velocity = pushDir * pushPower;
     }
    
    
  3. I drag the file into "First Person Controller" on "Hierarchy window"

And thats it, i can push all objects with Rigidbody :)
