Sonic trampoline style with character controller(old one)

Character Controllers move when the Move() function is called and a Vector3 is provided. This Vector3 can be calculated in a number of ways.

 //How fast we move
 var moveSpeed = 6.0;
 
 //Gravity strength
 var theGravity = 20.0
 
 //How fast up or down we are going.
 private var verticalSpeed = 0.0;
 
 var controller : CharacterController;
 
 //This is the vector the Move() function uses.
 var finalMovement : Vector3;
 
 function MovementUpdate () {
 
     //Define the input we can get from a player
     var vertical : String = "Vertical";
     var horizontal : String = "Horizontal";
 
     //Next we calculate the horizontal moment from the input values
     var zxMovement = Vector3(horizontal, 0, vertical) * moveSpeed * Time.deltaTime;
 
     //After this, we calculate gravity.
     verticalSpeed -= theGravity * Time.deltaTime;
 
     //But if the controller is on the ground, we set the vertical speed to zero to prevent dropping off the edge.
     if(controller.isGrounded) {
         verticalSpeed == 0;
     }
 
     //Now we calculate the final vector
     finalMovement = zxMovement + Vector3(0, verticalSpeed, 0);
 }
 
 function Update () {
     MovementUpdate();
     controller.Move(finalMovement);
 }

After this, a spring simply sets the vertical speed to something high.

Add this after the Update in the last script.

 function SuperJump (strength : float) {
     verticalSpeed = strength;
 }

Then add a script to the object you want to do the launching that calls the SuperJump() and provides a strength.

 var strength = 25.0;
 
 function OnTriggerEnter(col : Collider) {
     //Make sure to name the controller script "PlayerController" or else this won't work!
     if(col.GetComponent(PlayerController)) {
         col.SendMessage("SuperJump", strength);
     }
 }

This is just the basics. Hopefully I didn't typo something. xD. Anyway. Hope this helps!
