2D colliders are not working as expected.

I’m having an issue with my 2D game’s code…

Collider2D[] colliders = Physics2D.OverlapCircleAll(wallspawn.transform.position, 1f, 0);
                    if (colliders.Length == 0)
                    {
                        CmdWallSpawner();
                    }
                    else
                    {
                        Debug.Log(colliders);
                    }

This should see if there are any objects on the default layer, where I put my building blocks, and other collidable objects… but It still allows me to place an run the CmdWallSpawner() function even if there is something in that area…

Hello.

Try this:

Collider2D[] colliders = Physics2D.OverlapCircleAll(wallspawn.transform.position, 1f,  LayerMask.GetMask("Default"));

instead of

Collider2D[] colliders = Physics2D.OverlapCircleAll(wallspawn.transform.position, 1f,0);

Zero is index of Default layer only in inspector (Dunno why). The real index of Default is 1 but GetMask("Default") is the best solution for this.
