Some rare seeds will cause an NPC, in this case Wandmaker, to get stuck in an infinite loop trying to spawn.
I could have perhaps made a fix and do a PR on Github, but as there are several ways to address it, as well as the possibility similar issues might happen with Ghost or Imp, I'm posting here.
Issue:
Game freeze. Wandmaker is stuck in an infinite loop attempting to spawn.
File:
.../core/src/main/java/com/shatteredpixel/shatteredpixeldungeon/actors/mobs/npcs/Wandmaker.java
Method:
Lines:
305-321
Reproducibility:
Game seed RAT-KCA-BLR will attempt to spawn Wandmaker on floor 8 in a 7x7 room (see screenshot), within the middle 3x3 area. All tiles here are considered not valid due to traps, entrance, or non-solid ground, including the bridge.
Suggestions:
- Limit number of spawn attempts (ie. 100). If failed, consider trapped locations to be valid, optionally erasing any trap under the Wandmaker.
- Alternative is to spawn a new room with same width/height after x attempts, overwriting the old room and try again.
This man HATES community contributions.
That's a pretty big mischaracterization. I don't accept code contributions both because I prefer to keep Shattered solo, and due to copyright implications. Community contributions in other forms, such as bug reports, are of course welcome.
