Knockback is not compatible with the argument list '()'.

how would i go about fixing it

Code (JavaScript):

1.      public var speed : float = 15.0;
2.      public var duration : float = 0.25;
3.    
4.      private var controller : CharacterController;
5.      function Start(){
6.          controller = GetComponent(CharacterController);
7.      }
8.      function Knockback(direction : Vector3){
9.          var startTime = Time.time;
10.          while(Time.time < (startTime + duration)){
11.              controller.SimpleMove(direction*speed);
12.              yield;
13.          }
14.      }
15.      function OnControllerColliderHit (hit : ControllerColliderHit) {
16.     Knockback();
17.     }
18.  

 

Knockback is a function with the argument "direction", which is a Vector3. So to call Knockback you have to plug in a Vector3 as an argument, like:

Code (JavaScript):

1. Knockback (thisIsMyVector3Variable);

 

what do i use for the vector 3 variable?
