Rigidbody AddForce Forcemode.Impulse not working 2D game...

Question

Every time i try to use addforce with impulse as the forcemode, the object will not jump, but if i remove the impulse forcemode it will jump, what i am doing wrong :S?

this is my script...

 void Update()
     {
         if (Input.GetKeyDown(KeyCode.W)) {
             Vector3 _jump = new Vector3(0,10,0);
                 this.gameObject.rigidbody.AddForce(_jump, ForceMode.Impulse);
         }            
     }

Impossible to know exactly without more info, since many things could be effecting this (gravity, drag, mass, other forces, etc.) However, if you're using a Rigidbody2D then your code should probably be:

        gameObject.rigidbody2D.AddForce (Vector2, ForceMode.Impulse)

You should also be caching the Rigidbody reference in OnStart for best performance.

Use ForceMode2D instead of ForceMode:

 gameObject.rigidbody2D.AddForce (Vector2, ForceMode2D.Impulse);
