prop_vehicle_apc

prop_vehicle_apc is a point entity available in Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Half-Life 2: Deathmatch.

A prop_vehicle_apc using its typical models/combine_apc.mdl model.

Entity description

A Combine APC vehicle with mounted guns, that can be blown up and driven by a vehicle driver or a npc_apcdriver.

It can not be driven by the player, even with a different vehicle script file. (It is "enterable", but that's it. You will just get stuck under the vehicle, facing to the right, and most importantly won't be able to exit the APC again. To prevent the vehicle from being entered, you should set its VehicleLocked (Start locked) keyvalue to Yes.)

The APC should generally be given the models/combine_apc.mdl world model and the scripts/vehicles/apc_npc.txt vehicle script file. To have the APC drive and/or shoot, create an npc_apcdriver and assign the APC to its vehicle (Vehicle to drive) keyvalue.

The wheels of the prop are not solid, but you can prevent the player going through them by immersing them within one or more Player Clip brushes.
