I don't need to test my programs. I have an error-correcting modem.

UT2004 :: Actor >> Triggers >> QuickVehicleFactory

By VitalOverdose


I made this actor mainly for testing vehicles on DeathMatch levels but I've now added some code to be able to use it in Onslaught Levels.Its subclassed from Triggers because it was far less complicated than trying to modify a normal VehicleFactory just to do a simple spawning task.


  • You can make a list of vehicles to spawn.
  • If used in an ONS level the QuickVehicleFactory will work independent of what ONSPowerNodes are controlled.
  • It take its team from the nearest power core;
  • Spawns vehicles as they are destroyed.
