# AI and NPCs

## Theory

* NPCs in the game world are spawned via two different ways:
  * Crowd NPCs
  * Community NPCs

### Crowd NPCs

* Crowd NPCs are as the name suggests spawned as part of the regular crowd that walks the street, they are not fully understood yet

## Community NPCs

* Community NPCs are all the other NPCs, that includes everyone from the shopkeepers, quest NPCs, enemy NPCs to NPCs hanging out in specific spots
* Communities allow to define a wide combination of things, allowing for very dynamic setups (E.g. NPC type, amount and spot depending on the time of day):
  * What NPCs
  * When should they spawn
  * How many
  * Where should they spawn
  * Setups such as making them patrol along a spline

Communities can not only be used for spawning an placing NPCs, but anything that has a TweakDB record, e.g. Vehicles
