Construction

Making an Emplacement

  1. Create an emplacement for your mounted gun. All Survivor NPC's will not take damage and do not interact with survivors or infected. Having this emplacement accessible to zombies will interfere with suspension of disbelief.
    Consider placing your mounted gun in a location that appears inaccessible to common infected to hide the NPC's invulnerability.
  2. Add a prop_mounted_machine_gun to the emplacement. Ensure you have the right gun. Neither prop_minigun nor prop_minigun_l4d1 will work in this situation.
  3. Add an area for the NPC to spawn in. If you want the survivors to see the NPC walk to the gun, ensure they cannot see the NPC when it spawns, as it will appear out of nowhere.

Adding the NPC

  1. Create four info_l4d1_survivor_spawn where you want the NPC to be created. Set their "Character" field to your desired bot. Name all four info_l4d1_survivor_spawn "L4D1_Bots".
  2. Create four prop_dynamic nearby, using the L4D1 player models. This is done to precache the models. Name all four prop_dynamic "L4D1_Models".
  3. Create a logic_auto. (Any entity capable of firing outputs will work)

Set its outputs as follows:

  My Output Target Entity Target Input Parameter Delay Only Once
Io11.png OnMapSpawn L4D1_Bots SpawnSurvivor 0.00 No
Io11.png OnMapSpawn L4D1_Models Kill 0.01 No
