Raycast go through NGUI buttons

[wijesijp]

I am building a Unity game for mobile. I have implemented touch tracking system for it to move game object around.

1. foreach (Touch touch in Input.touches)
2.                 { ...}

When the user finishes moving I do a raycast and find out the object it hit.

When I add NGUI interface to the game the raycast is going through the NGUI buttons. 

Is there a NGUI touch system that I can use to manage game objects?

You're the one doing a raycast. Specify a mask that doesn't involve the GUI and it won't hit it.
