View unit's height

[the Immortal]

I'm making an ability that can be casted only in water. To do so I need to check the 'height' of the unit and if it's below 0 to allow it to cast the spell. The question is how to check it?
I tried Crow Form - stuff, but the flying height isn't affected from the terrain deformations.

PS. Yes, I know I can do it via terrain check, but this won't work for my map
So, how to check it?

Add and remove the crow form and use real comparison unit flying height. If this doesn't work then I can only think using regions if you don't want to use a certain tile for water parts.

Condition - Real Comparison

Something like that.... maybe a string.. not too sure about height.

You could place a Terrain-Type everywhere there is water instead. Then check to see if the Unit is on the Terrain-Type and Add / Remove the Ability when necessary. Of course this is not exactly a perfect plan but it may suffice.

I use all terrains that look good for the water somewhere else in the map, so I will use this only if there is no other way.

The flying height stays 0 but I can lift up and down the unit.

So any other ideas pls?

I think I remember something ... what was it? The caster system?

Yeah, maybe it was the Caster System (by vexorian I think) that had tools for detecting if you were in water or not. (You can get it at wc3campaigns.com)

I could be completely wrong, but its worth checking out anyway.

10x, I will check it when I go home

how about... some high lvl trigger stuffs. first create a dummy that can build building and create a building that can only be buildable in water. then in the trigger when u use this ability, create a dummy, order it to build near to your hero. Be sure to amke your building using scout tower as it will be easier because of its size when you build. Then if you the dummy is building, means your hero is in water! weee~ if it is not, then too bad... so you will need 1 dummy unit 1 dummy building 1 dummy skill 1 dummy trigger 1 dummy program.

is Z Height what your looking for? It detects the height of the unit from flat 0. And also can go negative.

Custom script:   set udg_LocZ=GetLocationZ(udg_Casting_Position)

LocZ being a real variable and Casting Position being a point variable where caster is.

Then use if then else for LocZ less than 0 or whatever. Thats all there is to it.

The answer is extremly hard, you should use Caster System if you are tired of rects and regions.


Here the steps to do with rects/regions.

1 - Create rects that is only in waters.
2 - For each rect you created, and them in a region we will call Region (Region variable).
3 - Create your trigger that is only castable on water. I will show you how to do that.
