Im creating ladders in my 2D game. Help!

Unity Engine
1

Hi. Im trying to make a 2D game, which will have ladders- but its not working. There are no errors. But its not working Heres my script, which I put on character.

var speed = 3.0;
function OnCollisionEnter(Bam : Collision)
    {
    if(Bam.tag == "Ladder")
        {
       var controller : CharacterController = GetComponent(CharacterController); 
 
       var forward = transform.TransformDirection(Vector3.up);
       var curSpeed = speed * Input.GetAxis ("Vertical");
       controller.SimpleMove(forward * curSpeed);
        }
    }

That didnt work at all, even when i added Debug.Log s
Then i tried

var speed = 3.0;
function OnTriggerEnter(Bam:Collider){
	Debug.Log("Checking for ladder");
    if(Bam.Tag == "Ladder"){
		Debug.Log("Touching Ladder..");
		var controller : CharacterController = GetComponent(CharacterController); 

		var forward = transform.TransformDirection(Vector3.up);
		var curSpeed = speed * Input.GetAxis ("Jump");
		Debug.Log("Variables for movement made!");
		controller.SimpleMove(forward * curSpeed);
		Debug.Log("Moving Ready!");
        }
    }

Now im being spammed with Checking for Ladder- Yay! but It still doesnt detect a ladder and execute in the log here:

  if(Bam.Tag == "Ladder"){
       Debug.Log("Touching Ladder..");

I also set the Ladders tags to Ladder and their collidors to Trigger.

Are you using box colliders on your ladders? Or just the plane mesh collider?

Im using box collidors on the ladders. The box collidors also have “Is Trigger” to true

Help?!

Sure ladder is not with a small l?

OnCollisionEnter is not a update… You might want to use OnCollisionStay or when hitting the ladder setting a bool to true that does the same thing as when you hit the ladder (but then in the update function) and setting the bool on false at OnCollisionExit
