Ambush Example

v0.9.0 by: standardcombo

This example of an enemy camp spawns three enemies when the player enters the camp.

The NPCs will chase and attack players as long as there are players within the camp. When all players exit the camp, the NPCs return to their spawn points, go to sleep and eventually despawn.

See the NPC_KIT_README file for general info about the NPC Kit.

Camp Behavior

The camp's behavior is driven by the scripts 'NPCSpawner' and 'NPCCampBehavior_PlayerProximity'. These scripts define "When" and "How" to spawn NPCs. Each of the scripts has custom properties that can be tuned to adjust their behavior.

The Ambush camp is characterized by two triggers, one small and one large--also called the "Inside Trigger" and the "Outside Trigger". Adjusting the position, type and size of these two triggers is essential to correctly setting up an ambush-style camp.

The inside trigger is what detects players entering the camp and spawns the NPCs, while the outside trigger's job is to keep track of players who are present, so that when there are no more players in the camp the NPCs can be despawned.

Spawn Points

NPC camps are characterized by a number of spawn points that tell the spawner scripts "What" and "Where" to spawn. Each spawn point has references to the NPC templates which they will spawn. These are setup as custom properties. A spawn point can have any number of NPC templates assigned as custom properties. No specific names need to be given to those custom properties. The position and rotation of a spawn point determine the orientation of the NPCs that spawn from it. Spawn points are usually placed touching the ground and should be adjusted on uneven terrain.

This assemblage of parts is what allows NPC camps to come in all forms, to spawn all kinds of NPCs, in various compositions, and to behave in different ways as players approach or leave the area.
