    Hi! I am new to unity and to this forum, but I have been having trouble with my code. I have a gameObject called spawnedObject and each layer is properly labelled "Foreground." I have my code here:
    Code (CSharp):
    1.  
    2. if (spawnedObject.GetComponent<EdgeCollider2D().IsTouchingLayers(LayerMask.GetMask("Foreground")) == true){
    3.             Debug.Log("is touching another foreground");
    4.             }
    5.  
    The debug.log never pops up, even if the gameObject is clearly touching a gameObject from that layer. Any help would be appreciated in figuring out why my code won't work.

    How did you get it there? If you drag it there or move it by .Translate() or setting .position, you are bypassing the physics engine.

    Always use the .MovePosition() / MoveRotation() method(s) on the Rigidbody / Rigidbody2D.

    Thank you for replying! I basically spawn my gameObject into my world and I want to ensure that it does not collide with another gameObject when spawning in.

    IsTouchingLayer checks for existing contacts, it doesn't perform a query of the world so if there's not been a simulation step then there won't be any contacts for a new collider so it'll not show as touching anything.

    If you want to do this before a simulation step then perform one of the many queries such as OverlapCollider.

    Please note that there's a dedicated Physics forum for this kind of stuff.
