Resolved OnTriggerEnter2D was working fine yesterday, but today nothing is happening.

Hello,

Yesterday I was working on making chests spawn random items when the player collided with them. It was working fine. This morning I realized the trigger is no longer firing. The player walks right through the chest and nothing happens. The chests work if I implement a GetKeyDown on Update but no longer with OnTriggerEnter2D. I am very confused on why it decided to stop working today. Has anyone ever run into an issue similar to this?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.InputSystem;
5. using TinyScript;
6.  
7. public class Spawner : MonoBehaviour
8. {
9.     public LootDrop Loot;
10.     public int RandomDropCount = 1; // should be adjusted to drop equal to player count
11.     public float DropRange = .5f;
12.     private Animator animator;
13.  
14.     // Use this for initialization
15.     void Start()
16.     {
17.         animator = GetComponent<Animator>();
18.     }
19.    
20.     private void OnTriggerEnter2D(Collider2D collision)
21.     {
22.         if (collision.gameObject.GetComponent<Chest>())
23.         {
24.             Debug.Log("Chest Contact");
25.             animator.SetBool("opened", true);
26.             //animator.SetBool(Settings.use, true);
27.             Loot.SpawnDrop(this.transform, RandomDropCount, DropRange);
28.  
29.             gameObject.GetComponent<BoxCollider2D>().isTrigger = false;
30.  
31.             // if "opened" is set to true
32.             // do not spawn anymore items
33.             Destroy(this);
34.         }
35.     }
36.  
37.     /*

40.         Loot.SpawnDrop(this.transform, RandomDropCount, DropRange);

From your screenshot your Chest object doesn't seem to have the Chest component attached to it.

 

Its on there. Here is a screen shot will all the components.

 

Wait Spawner is on the Chest? Based on the code it should be on the player. It's expecting the OTHER object to have a Chest component on it.

 

Ok, I edited the code. This fixed the issue with the chests. I also want the enemy's to drop items from a different loot table so an issue come up when the Player collides with enemies but for now the chest issue is fixed. Thanks!
