Question by meanmax · Nov 26, 2013 at 10:15 PM · rigidbodyaddforcecube

How do I make a cube fly along a single axis.

In my game I am trying to make it so that when a cube hits a player the player gets knocked off the platform. I have looked at a few ways to do this but I would like to try and use the rigidbody.AddForce function. this is the code I have so far:

 #pragma strict
 
 //var rocket : Rigidbody;
 // speed = 10.0;
 
 var numEnemies : int = 3;
 
 function Update () {
 
     for(var i : int = 0; i < numEnemies; i++)
     {
         rigidbody.AddForce(Vector3.forward*500,ForceMode.Acceleration);
     }
 
     //var rocketClone : Rigidbody = Instantiate(rocket, transform.position, transform.rotation);
 
     //rocketClone.velocity = transform.forward * speed*1;
 
 }

The code works but only once and then stops. so I tried to add a for loop but it does not work :( can anyone help please?

Thanks

Rather than "AddForce", I suggest that you merely add to the rigidbody.velocity. If you do use AddForce, you should probably use ForceMode.Impulse.

 for(var i : int = 0; i < numEnemies; i++)
 {
    
    rigidbody.velocity = Vector3.forward * 500;
 
    // OR
 
    rigidbody.AddForce(Vector3.forward*500,ForceMode.Impulse);
 }
