grad-civs: population zones & transit traffic

step by step

enable grad-civs

just for debugging purposes, choose to show civilians on map

place modules and a player unit like so

• put population zone module anywhere
• place a trigger and size it to the area you want civilians to spawn into.
• sync (connect) the trigger to the population zone module
• set a player unit somewhere close, but not too close to the population zone - at default settings,
  • people living in homes will spawn in 500m to 1km distance from players
  • foot patrols will spawn between 1km and 1.5km away from the next player
  • people driving cars will spawn between 1.5km and 4.5km away from the next player
• put transit traffic source and sink modules and sync them. these will always spawn traffic, regardless of player distance and population zones.

start into singleplayer and wait ten seconds

---

note

• there's different types of civilians. some need houses to spawn. you wont get a bunch of civs sitting around in no mans land.
• different types of civilians will only spawn when they're within a certain distance of players (minimum & maximum). look at the settings and see what suits you best.
• the algorithm that looks for suitable spawn positions is fairly stupid. make sure population zones are not too small (couple hundred meters diameter at least)
• if you place no population zones, the whole island will be considered to be a population zone
