Revision: 1.112
Committed: Tue Apr 24 00:42:02 2007 UTC (17 years, 1 month ago) by root
Content type: text/plain
Branch: MAIN
Changes since 1.111: +74 -83 lines
Log Message:
- implement a rudimentary framework for a "msg" command that
  replaces drawinfo and drawextinfo and allows for simpler usage
  in simple cases and extensibility for the less complex uses.
- moved the character race choosing logic into perl, making use
  of the new msg command if the client supports it.

500 * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding

502 * 2) I think the old code was broken if the first direction the monster

504 * verifying that the player can actually move in that direction. The new
505 * code does not store anything in firstdir until we have verified that the
506 * monster can in fact move one space in that direction.
507 * 3) I'm not sure how good this code will be for moving multipart monsters,
508 * since only simple checks to blocked are being called, which could mean the monster
509 * is blocking itself.
