darkwulfv	How do I check to see if a unit is on water or not? (Yes I know the theme of the spell session requires me to know this. That's why I'm asking Any help?)

Alevice	Trigger: Conditions (Terrain pathing at (Position of (Triggering unit)) of type Floatability is off) Equal to False JASS: function UnitIsInWater takes unit whichUnit returns boolean return not (IsTerrainPathable(GetUnitX(whichUnit),GetUnitY(whichUnit),PATHING_TYPE_FLOATABILITY)) endfunction

Anitarf	How did Blizz implement this pathability anyway? I thought that the RGB channels of pathing maps were used for air, ground and buildability.

Naakaloh	I'm not sure, but when I was designing a water-based spell I checked the pathing types and floatability worked for all the places with water. I think that there may be a separate method of pathing water, since it's clear the the RGB textures weren't designed for it... unless they made the alpha value have some effect.

Captain Griffen	Notice naval and ground pathings are different options in the WE for viewing them.

Naakaloh	Yes, that's partially why I was thinking that there is a different method.
