Summary

0003200: Shafts/hatches predictably place you on the same co-ordinates on the destination floor

Description

I'm not sure what the intended behaviour is (I think 0.6/0.7/trunk all behave differently, and 0.7 is buggy), but in trunk going through a shaft or escape hatch will always place you on the same co-ordinates on the destination floor - that is, if you go through a shaft with co-ordinates 27,27 on D:26, you will always land at 27,27 on D:27 (if there is a wall in the way you will be placed as near as possible to that spot).

This can be abused with Flight and Minefield cards (and possibly also weapons of chaos?), which create shafts. By creating a shaft at a known co-ordinate, you can drop onto a lower level and be certain that you will arrive in a specific spot. By mapping the destination level first, you can drop yourself directly into the Zot:5 orb chamber, for example.

The destinations of escape hatches and shafts should probably be random, or else players shouldn't be able to create them (although this would still let the destination of existing shafts/hatches be predicted).

Notes
(0010427) jpeg (manager) 2011-01-13 09:39	Sounds good. Picking a random destination place when used (for shafts) or on first use (for escape hatches) should work. Should the target position get blocked by monsters, walls, deep water, drop the player somewhere nearby as already happens currently.
