699 |
|
|
* INS_NO_MERGE: don't try to merge inserted object with ones alrady |
700 |

|
* on space. |
701 |
|
|
* INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor. |
702 |
|
|
* INS_NO_WALK_ON: Don't call check_walk_on against the |
703 |
|
|
* originator - saves cpu time if you know the inserted object |
704 |
|
|
* is not meaningful in terms of having an effect. |
705 |
|
|
* INS_ON_TOP: Always put object on top. Generally only needed when loading |
706 |
|
|
* files from disk and ordering needs to be preserved. |
707 |
|
|
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
708 |
|
|
* Use for treasure chests so the new object is the highest thing |
709 |
|
|
* beneath the player, but not actually above it. Note - the |
710 |
|
|
* map and x,y coordinates for the object to be inserted must |
711 |
|
|
* match the originator. |
712 |
|
|
* |
713 |
|
|
* Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY |
714 |
|
|
* are mutually exclusive. The behaviour for passing more than one |
715 |
|
|
* should be considered undefined - while you may notice what happens |
716 |
|
|
* right now if you pass more than one, that could very well change |
717 |
|
|
* in future revisions of the code. |
