Hi forum. What I want to ask in this thread is as follows:

I have a fish spell, which of course needs to be cast only in water. So It's a "Target Ground" Spell. I need a condition which will allow me to check if the point of ability being cast is in water or not. How is that doable ? :?

Ty in advance.
 
Explain please. How can a unit be spawned only in water?

And what I need is, an immediate reponse. Like if cast not on water - u get a message "Can't fish here" and if it is in water, the unit is paused and the triggers begin, u see what I mean ?
 
A boat, and i don't think a message saying they can't fish on land is necessary, it just won't go off.

Though if you want, after unit is created, set tempunit = lastunitcreated
then if
tempunit = no unit

You can't fish here you nub
