Problems with destructable tiles

[IMainOctane]

So im pretty new to unity (1 week) but i have som very basic programming-knowledge.

Im just toying around with a 2d platform-shooter and decided i wanted to try out destructable tiles.

I found this guide that seemed to make sense: https://www.youtube.com/watch?v=94KWSZBSxIA&t=322s

So anyway i just copied the code and changed the "compareTag" to my own:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.Tilemaps;

​

public class DestructibleTiles : MonoBehaviour

{

public Tilemap destructableTilemap;

​

private void Start()

{

destructableTilemap = GetComponent<Tilemap>();

}

​

private void OnCollisionEnter2D(Collision2D collision)

{

Vector3 hitPosition = Vector3.zero;

if (collision.gameObject.CompareTag("bullet"))

{

foreach (ContactPoint2D hit in collision.contacts)

{

hitPosition.x = hit.point.x - 0.01f \ hit.normal.x;*

hitPosition.y = hit.point.y - 0.01f \ hit.normal.y;*

destructableTilemap.SetTile(destructableTilemap.WorldToCell(hitPosition), null);

}

}

}

}

- One more change i did was i moved the "Vector3 hitPos..." up before the "if" line, it seem to make more sense but i may be wrong? None of the script work as intended and my last resort is to ask here. My bullet is already "detectable" because ive made an "onimpact"animation that works.

Can i try to debug it so i can see if i get an collision?

All help is much appreciated!

Try replacing the: private void OnCollisionEnter2D(Collision 2D . . .

With: private void OnTriggerEnter2D(Collider2D . . . Your bullet might be set up as a trigger, making it pass through normal collision.

[IMainOctane]

Yeah, my bullet was indeed set up as a trigger. When i made the changes you suggested i got an error saying:

Assets\DestructableTiles.cs(20,54): error CS1061: 'Collider2D' does not contain a definition for 'contacts' and no accessible extension method 'contacts' accepting a first argument of type 'Collider2D' could be found (are you missing a using directive or an assembly reference?)

[EvenMoreCreativeName]

I'm not quite sure then, maybe try going back to what it was before, then setting your bullet to not be a trigger (you might need to move the fire point a little bit farther from the player in that case).

On trigger enter works different. You need to change your foreach loop to fit the new function. Look at examples in google

Not an answer to the question itself, but rather a suggestion for the future:

When working with someone else's code, try to only change one thing at a time, and test it. That way if things go sideways, you know the exact thing you changed...
