Raycast2D & edgeCollider

does the raycast2D detect hit of edgecollider?
im asking because i have been trying to detect hit with raycast2d with a layermask filter but something is going wrong. the layermask that is 8th layermask, i have been trying with 1 << 8 bitmask check and with public layermask inspector check but nothing helps... plus the hit detects the ignored layermask collider ... how is that even possible?

I've run into this before so I know what's up. =p

Your code from Unity Answers:

Code (csharp):

1. RaycastHit2D hit = Physics2D.Raycast (transform.position, Vector2.up, 1 << LayerMask.NameToLayer ("field"));

Look closely at the third parameter on the documentation.
http://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html

The third argument should be DISTANCE, but you are putting in a LAYERMASK.

If you want to raycast for an infinite distance, put float.PositiveInfinity as your third argument and move the Layermask to the forth argument.

 

you are the man!
