I think i have tried everything but i simply can't make a unit have no collision (which can also pass through units and trees/cliffs) and move in a straight line. So if there are trees and the unit has no collision if you want the unit to move to the other side of the trees the unit will go round it even though it can move through them. Same goes for cliffs. Any ideas how to make the unit go straight? Its a spell and when i cast it i want to get this effect. The unit should not be always a flying unit or so.
