look in KFMod -> Classes -> HUDKillingFloor.uc
You can change the HUD type by creating a custom game type that extends KFGameType and delete everything except default props. Simply modifiy anything you want in there. Now to make it load that gametype create a mutator similar to this(you might have to adjust it):
class Something extends Mutator;
function postBeginPlay()
{
local string currentmap;
if(TestGameType(level.game)==none)
{
currentmap=GetURLMap(false);
level.servertravel("?game=KFTestMut.TestGameType",true);
}
}
defaultproperties
{
GroupName="KF-Deeskjack"
FriendlyName="Test Gametype"
Description="Upcoming project for Killing Floor. EARLY ALPHA TEST! Made by YoYoBatty July 19 2010."
bAlwaysRelevant=True
RemoteRole=ROLE_SimulatedProxy
bAddToServerPackages=True
}
Of course that is an example and you need to change the names around so the classes match up with your modded gametype.
Good luck and if you have any questions just PM me!
