How to use OnTriggerEnter? (JS)

Ahoy,

This is a problem I have been dealing with for a while but never knew how to fix.

How do I get OnTriggerEnter to work?

In this script the player object has a rigidbody attached, so it should work, but absolutely no dice. I know it’s kind of a noob question, but it’s really bothering me since I need to finish this game for the GGJ 2015. The game is 2D, if that helps.

var facingRight : boolean = true;
var facingLeft : boolean = false;
var jumped : boolean = false;
var debug : boolean = false;
var ground : Collider2D;

function Update () {

	if (Input.GetKey(KeyCode.D)) {
		if (facingRight) {
			transform.Translate (0.1, 0, 0);
			facingRight = true;
			facingLeft = false;
		}
		if (facingLeft) {
			transform.Rotate (0, 180, 0);
			facingRight = true;
		}
	}
	
	if (Input.GetKey(KeyCode.A)) {
		if (facingLeft) {
			transform.Translate (0.1, 0, 0);
			facingLeft = true;
			facingRight = false;
		}
		if (facingRight) {
			transform.Rotate (0, 180, 0);
			facingLeft = true;
		}
	}
	
	if (Input.GetKeyDown(KeyCode.Space)) {
		if (jumped == false) {
			rigidbody2D.velocity = Vector2(0,6);
			jumped = true;
		}
	}
}

function OnTriggerStay (ground) {

	jumped = false;
	debug = true;
}

Thanks.

Question seem a bit large. Unity - Scripting API: MonoBehaviour.OnTriggerEnter(Collider)

It’s triggered when you hit something with an other ridged body. Don’t forget to added the type of variable to the triggered argument. Like ‘ground : Collider’ Dont declare a collider beforehand i’ts sendt with the event. So remove your declaration of ground. It’s not needed.
