Terrain modification aura (was: Help with world edit)

[huge_leb_man]

how do i make a trigger spell/aura so that when the spell is active the terrain below the caster will change to ice but will go away as they walk, Like the terrain will only be below the caster and will change back once the caster moves.

I don't know if there is a way to change the actual terrain tiles through triggers/abilities (except for blight), but you could find a doodad/unit/other effect, edit it (either lower it so just the top part of it is visible above ground or scale its z axis so it is essentially flat) and attach it to the unit when the spell/aura is active.

It can be done in Jass using [ljass]GetTerrainType(...)[/ljass] and [ljass]SetTerrainType(...)[/ljass].
