how do u get units to walk on a pier

whenever i order units to walk on piers in my map, the walk through them. can u help? thx

dont u have do it in trig or sumthing

maybe try putting invisible platforms where the piers are..

now they go through the pier and into deep water

try changing the size of the platforms until they fit with the size of the pier.

no no no
just make a new ramp, based off of a bridge, then change the model file to the pier and your done. the units will walk on it

Why not just put invisible platforms all over the pier as said. Then change their height to match the pier.
