I don't know if you can make all of the buildings on the map invincible but I know you can do it for one building at a time, Put this in the init line of an object or Game Logic "(nearestBuilding this) allowDamage false;" maybe you can try "(nearestBuildings this) allowDamage false;"?
So the animations for the wheels of the truck are screwed up and they don't actually turn, I've been looking around like crazy in the config and I can't find out what it is I need to fix. If anyone could help me, it would mean the world to me.
