Turret targeting
Configured targeting also changes the tame-target policy; actual AI eligibility still applies.

Practical guidance
EditorialBurning fireplaces consume elapsedSeconds/secondsPerFuel when enabled and not infinite. Terrain, overhead blockage, smoke and optional submersion can prevent burning. Wet conditions select low/high objects and can turn off fireplaces configured to allow toggling. Cinder emission requires ownership, rejects positions inside a shield, and passes a decremented spread budget to its children. Its periodic branch additionally needs a positive spread budget, chance success and a burning fireplace when attached. Fire spread is enabled in Ashlands or by the Fire world key; burnable objects, liquid height, wetness, cleared terrain and biome gates apply. Fire damage visits characters but randomly selects one eligible non-character collider per tick. Rain and accumulated smoke can extinguish spreading fire. Effect areas refresh heat/status exposure; base value counts matching colliders rather than unique buildings.
Turret attack needs target, aim threshold, ammo and elapsed cooldown. A shot emits at most one projectile even if ammo specifies more; maxAmmo zero means unlimited. Projectile damage comes from selected ammo. Configured trophy shared names expand to character targets and select the configured tamed-target policy. Optional destruction returns remaining ammo.
