Add PlaceDefenseTowardsEnemyChance trait to basebuilderbotmodule. This defeaults to 100 which is the current behavior. This change now allows you to set the chance that bots will place defenses evenly around the base like the AI in stock red alert and Tiberian sun did.
- FrozenActorsInRegion now filters for valid and (optionally) visible FAs
- Add new FrozenActorsInCircle to mirror World.FindActorsInCircle.
The first change means that SupportPowerDecision now correctly ignores
FrozenActors that the AI has not discovered.
