If a point is in water

Is there a way to detect if a unit or a point is on water? I need to have something like this as a condition so that a unit will be created at a target location but only if there is water there.

I still recommend this. It distinguishes between shallow water and deep water. If you just want to know 'water,' then chobibo's will work fine. (First two arguments are X,Y)

It looks like dusk's system works better than just using the native implementation, which is bugged.

Ok, thanks guys. I will try one or both of these methods tonight.

EDIT: I got Dusk's function to work first try so that's good :P
