Unity，BoxCollider2D，碰撞但不触发

Question

I have 3 gameObjects: "Player" (with BoxCollider2D) Weapon with (script attached, BoxCollider2D(isTrigger = true)) and "Enemy" with (BoxCollider2D, and tag "Enemy") I put a script to Destroy the enemy upon weapon to Enemy collison but it just goes past enemy until the player collider pusher the enemy.

{   
    private void onTriggerEnter2D(Collider2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy"))
        {
            Destroy(collision.gameObject);
        }
    }
}```
    

Answer 1

That might be becuase you are using a collider, not a trigger. Try use OnCollisionEnter2D instead of OnTriggerEnter .

private void OnCollisionEnter2D(Collision2D collision)
{
    if (collision.gameObject.CompareTag("Enemy"))
    {
        Destroy(collision.gameObject);
    }
}

Answer 2

If you don't get any errors it looks like your handler method has invalid name in this context.

Change onTriggerEnter2D to OnTriggerEnter2D
