Can't get triggers to work.

I'm starting to make a game and I can't seem to get any triggers to work. What I've tried doing is once my player passes through a wall an object in the room becomes visible. I have set up the wall with a 2D Box Collider and have applied a rigid body on my player. My script is as follows:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Trigger : MonoBehaviour {
5.  
6.     public GameObject obj;
7.    
8.     // Update is called once per frame
9.     void OnTriggerEnter2D() {
10.         obj.SetActive (true);
11.     }
12. }

Any help would be greatly appreciated!

 

Make sure your player also has a collider2D object and make sure either the player's collider or the wall collider have the isTrigger box checked.

Thank you for the reply, but neither of these seem to be the problem

 

What is your Trigger script attached to?

Also, throw a Debug.Log("Triggered!"); into the OnTriggerEnter2D() function -- that way you'll know whether the problem is with the triggering or with the obj being set to active. (If the message shows, the trigger works.)

PS - I would imagine Unity would throw an error if it cares, but you might want to include the parameter that's passed into the OnTriggerEnter2D function:
void OnTriggerEnter2D(Collider2D other)

 

I tried this, and the Debug.Log doesn't even show in the console. :/
