Unity Raycasting a tag rather than layer
I have made a game where I use raycasting to determine whether or not the player is on an object. I know how to do this using layers, but I'd rather make it so it checks if it hits an object with a tag. Heres the code:
isObject = Physics2D.Linecast (this.transform.position, groundedEnd.position, 1 << LayerMask.NameToLayer ("Object"));
So rather than comparing to a layermask with the name "Object", I would rather it checked if it hits an object with a tag, but I do not know what to replace LayerMask with.
You can't use tags to change the way a raycast works. A raycast stops at the first thing it hits, skipping things not in the layerMask. You can't make it skip things based on tag. In other words, if a raycast would hit A with tag "friendly", then B with tag "enemy", it will always hit A and stop. If you used layers, you could make it skip layer "friendly" and hit B; but now way to ignore A based on tags.
The best you can do is RaycastAll, which gives you a list of everything on the path. Then search through the list, skipping certain tags on your own (you should be able to find an example using raycastAll, which shows this.)
