I am making a TD map with a similar concept to Mafarazzo TD. Now i made creeps and pretty much good moving triggers. I made unit Ghost (Invisible) and also seted up colision size to zero. And the creeps move like 2-3 sec and then stop and move again and stop again. I can upload screenshots if neccesary. Please help me becouse I have no clue about why is this happening when my colision size is 0. :banghead:
