Revision: 1.62
Committed: Fri Dec 22 16:34:00 2006 UTC (17 years, 5 months ago) by root
Content type: text/plain
Branch: MAIN
Changes since 1.61: +12 -4 lines
Log Message:
- preliminary check in, stuff is rudimentarily working
- moved most of the player creation process into a perl coroutine
- changed internal design of player management to not reuse
  and morph the object in funny ways. should be safer and much
  nicer to handle.
- got rid of some annoying hacks, such as clear()
  (TODO: get rid of player_pod and other stuff now unnecessary?)

438     * for both functions.
439     * Most are fairly explanatory:
440     * INS_NO_MERGE: don't try to merge inserted object with ones alrady
441     * on space.
442     * INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor.
443     * INS_NO_WALK_ON: Don't call check_walk_on against the
444     * originator - saves cpu time if you know the inserted object
445     * is not meaningful in terms of having an effect.
446     * INS_ON_TOP: Always put object on top. Generally only needed when loading
447     * files from disk and ordering needs to be preserved.
448     * INS_BELOW_ORIGINATOR: Insert new object immediately below originator -
449     * Use for treasure chests so the new object is the highest thing
450     * beneath the player, but not actually above it. Note - the
451     * map and x,y coordinates for the object to be inserted must
452     * match the originator.
453     * INS_MAP_LOAD: disable lots of checkings done at insertion to
454     * speed up map loading process, as we assume the ordering in
455     * loaded map is correct.
456     *
457     * Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY
458     * are mutually exclusive. The behaviour for passing more than one
459     * should be considered undefined - while you may notice what happens
460     * right now if you pass more than one, that could very well change
461     * in future revisions of the code.
