i have created a scene , on it i displayed gui elements, they r displayed but not working.
That is slider not moving , button is not clicking , edit box is not accepting input etc . Whats that ? How to solve

u might have drawn any GUI element over it. Check the code or give so that i can check it out.

With out looking at your code I'll have to say that you have not setup your event receiver.
