OK, I can shed a bit more light on these observations.
Turrets, traps, and landmines are all fixed now in the development build I'm working on. They'll work against any hostile creature - that's the correct logic here and you're absolutely right to question it.
The building destruction is intentional: only raiders during nighttime raids can damage structures, not regular wildlife. If you haven't seen a raid yet, keep exploring at night near your homestead and they'll come. But the conditions for raids might be too restrictive and/or poorly explained. Here's what triggers raids specifically:
1. Must be night (nightPhase >= 0.55)
2. Must be on the overworld (not in dungeon/ship)
3. Raid cooldown must be 0 (cooldown is set after each raid, varies by intensity)
4. Player must have explored at least 80 tiles from spawn (furthestDistance >= 80)
5. Player must be within 25 Manhattan tiles of their base
6. Then a probability roll each turn: base 1% + up to 4% from distance traveled + up to 2% from how deep into the night it is - so roughly 1-7% per turn
Have you seen a raid before in Adventure Mode? Reasons a player may not see a raid could include things like:
- Haven't explored 80+ tiles out yet (I doubt that based on how many hours you've played!)
- Aren't hanging around their homestead at night (they're in dungeons or far away exploring)
- Just got unlucky with the probability rolls - at early game (barely past 80 tiles), it's only ~1-2% per night turn
That 80-tile minimum + must-be-near-base combo is pretty restrictive for early game, now that I think about it more. A player who builds a homestead and immediately explores away from it will never see raids... that's not a bug but it's not really a feature either...
