399 |

|
* INS_NO_MERGE: don't try to merge inserted object with ones alrady |
400 |
|
|
* on space. |
401 |
|
|
* INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor. |
402 |
|
|
* INS_NO_WALK_ON: Don't call check_walk_on against the |
403 |
|
|
* originator - saves cpu time if you know the inserted object |
404 |
|
|
* is not meaningful in terms of having an effect. |
405 |
|
|
* INS_ON_TOP: Always put object on top. Generally only needed when loading |
406 |
|
|
* files from disk and ordering needs to be preserved. |
407 |
|
|
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
408 |
|
|
* Use for treasure chests so the new object is the highest thing |
409 |
|
|
* beneath the player, but not actually above it. Note - the |
410 |
|
|
* map and x,y coordinates for the object to be inserted must |
411 |
|
|
* match the originator. |
412 |
|
|
* INS_MAP_LOAD: disable lots of checkings done at insertion to |
413 |
|
|
* speed up map loading process, as we assume the ordering in |
414 |
|
|
* loaded map is correct. |
415 |
|
|
* |
416 |
|
|
* Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY |
417 |
|
|
* are mutually exclusive. The behaviour for passing more than one |
418 |
|
|
* should be considered undefined - while you may notice what happens |
419 |
|
|
* right now if you pass more than one, that could very well change |
420 |
|
|
* in future revisions of the code. |
