How do I spawn multiple bullets with rigidbodies in the same spot without them colliding-CodePudding

I am making a 2D game and have a basic weapon which I decided to call a pistol. I want to make a shotgun next and I have all of the work done except for the fact that they are all spawned in the same place and they all collide with each other.

I've had a few ideas like trying to turn off collisions for the rigidbodies (Didn't work), applying force without a rigidbody (Didn't work). I've done one game before this which was through a tutorial so this is my first real game and I just need help. If you need more details I can always send more. Thank you.

The script you need is the following line. In this line, Unity physics renders one collider ineffective against another.

Physics2D.IgnoreCollision(collider, ignoreCollider);

Also, with the algorithm below, you can neutralize all colliders at the moment of the bullet shot.

[SerializeField] private GameObject bulletType;

private List<Collider2D> _tempCollides;

void ShotBullets()
{
    _tempCollides.Clear();
    for (int i = 0; i < 4; i  )
    {
        // Instantiate and catch all colliders in a List
        var collider = Instantiate(bulletType, AnyPlace, AnyRotation).GetComponent<Collider2D>();
        
        _tempCollides.Add(collider);
    }
    foreach (var _collider in _tempCollides) // For Every Bullet Collider...
    {
        foreach (var _subCollider in _tempCollides) // .. Define to Ignore other Colliders..
        {
            if (_collider != _subCollider) Physics2D.IgnoreCollision(_collider, _subCollider);
        }
    }
}
