如何统一检查两个瓷砖地图之间的碰撞？

Question

I have two tilemaps. One can be moved with WASD (tiles are instantly moved to their new location) and I want to detect when the tiles of this tilemap collide with the tiles of another tilemap.

Both have tilemapcollider2d and both are set to be triggers.

They both have scripts attached with:

private void OnTriggerEnter2D(Collider2D other) {
    Debug.Log("touching");
}

However it's never triggered and I have no idea why. Making one or both rigidbody2d's doesn't change anything either.

Answer 1

You should use the tags on the colliding objects and compare for collision through the tags, like this:

private void OnTriggerEnter2D(Collider2D other) {
    if (other.gameObject.Tag == "tile"){
        Debug.Log("touching");
    }
}
