Child Nodes
Zombie spawns spawn wandering zombies when they are activated. These are the bread and butter of every coop map. Placing hundreds of these around the map will populate it with wandering zombies. Do not worry about placing hundreds of these around the map, this is normal and will not cause and fps issues. They are only activated once and are used by the AI director to figure out where to spawn wandering zombies.
Horde spawns are used a bit differently than zombie spawns. Horde spawns are where hordes and special infected are spawned from. These do not need to be placed as frequently as zombie spawns but should still be placed frequently enough for every location in the map to have a horde spawn nearby. This is so that if a horde event is activated the director can spawn a horde that can reach the player. A common place to put horde spawns is behind corners or on rooftops.
Boss spawns spawn boss infected when the director thinks a boss should be spawned. Boss spawns should always be placed along the path the player must see. This is because boss spawns are deactivated when the player looks at them, if the player manages to get past a boss spawn without seeing it, a boss may be spawned behind the player and the players will not face it. Good areas to place boss spawns are in corridors the players must go down or right before a saferoom.
Item spawns spawn items based on a preset or on a custom item you place in them. Item spawns activate when the parent node they are linked to activates. Item spawns can be placed in places the player can reach but does not necessarily have to go to. This can encourage exploration.
- Right clicking an item spawn with bare hands will change the item spawners preset and allow you to toggle through the different presets and change which item is spawned. (Default "Minor Healing").
- Shift right clicking an item spawn with bare hands will change the amount of items spawned when the item spawn is activated. If an item is not set to spawn 100% of the time, the amount of items spawned will vary and instead the spawner will try to spawn it this many times. (Default spawn once for each player).
- Right clicking with an item in hand will cause the item spawn when it is activated. Right clicking with the same item will change the chance the item has to spawn. (Default 100% chance to spawn).
