I have looked through about 6 pages trying to find a topic on this but failed. I am wondering how to make a vehicle like a 'Hog a hill for king of the hill style games, or use vehicles in this same manner for other game types.
Thats pretty much it. You spawn a vehicle then set it as whatever objective item you like. Its under Advanced, you change the gametype label while editing the map with the Forge mode as the right game type. If you want a warthog as a hill you would load Forge with King of the Hill, then spawn a Warthog and set its label to KotH Hill (or whatever the label is). You can't use objects or vehicles as bombs or flags though.
Wow, didn't even know this was possible. A "hill" game where the hill is a warthog would be incredibly fun, especially if you set the thing to respawn at a fixed point whenever it gets destroyed.
