Question

I have 2 monsters and 1 player. when players shoot, i get this mistake and they stop shooting. I have the same code for players, but players can keep shooting. I think the problem is with "destroy" but I can not find a solution enter image description here

    public class SpawnBulletController : MonoBehaviour
{
    public GameObject bullet;
    public float interval = 1F;

    // Use this for initialization
    void Start () {
        
            InvokeRepeating("ShootBullet", interval, interval);
        
        
    }

    void ShootBullet()
    {
        GameObject g = Instantiate(bullet, transform.position, Quaternion.identity);
        
    }
    

}

    public class BorderCollision : MonoBehaviour
{

    private void OnCollisionEnter2D(Collision2D other)
    {
        
        if (other.gameObject.tag != "Player")
            Destroy(other.gameObject);
    }
}

Answer 1

When your collider hits any GameObject that has no "Player" tag the GameObject will be destroyed this is wrong.

you should try

private void OnCollisionEnter2D(Collision2D collider)
{
    
    if (collider.gameObject.tag == "Monster")
        Destroy(collider.gameObject);
}

And if you want to destroy more with the same code but not with the same tag you should try.

private void OnCollisionEnter2D(Collision2D collider)
{
    
    if (collider.gameObject.tag == "Monster" || collider.gameObject.tag == "Monster2")
        Destroy(collider.gameObject);
}
