is it possible to make it so a unit can go throught other units? i have been looking at other threads i have seen answer about windwalk, the problem is i dont know if hero will always manage to use windwalk, he can be stunned sometimes. more over the windwalk changes the way hero looks. it gives him the art transparency effect and i dont really want it the invisiblity from soccer doesnt allow you to go throught other units, it just makes unit invisible adding ghost ability to units, i dont know really i have a lot of units, i would have to create temp groups near the target to add ghost ability to all units then remove ability, and if units walk too far then ghost ability might not be removed from them. i cannot turn off colission for unit because then he can walk throught tress and cliffs and i dont want that i just need a way to make unit able to walk throught other unit. if you need to know what i need it for then its for knockback, if unit X is knockbacked while unit Y is behind him then unit x will be stuck and wont be moved because unit Y is blocking him. that could be solved by adding walkability checker and turning colission for unit off, but the problem is that i dont really trust walkability checkers, the one is use is bit buggy and it sometimes throws units into tress but hardly ever, maybe some 1 could share a proper walkability checker?
