* originator - saves cpu time if you know the inserted object |
| 399 |
* is not meaningful in terms of having an effect. |
| 400 |
* INS_ON_TOP: Always put object on top. Generally only needed when loading |
| 401 |
* files from disk and ordering needs to be preserved. |
| 402 |
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
| 403 |
* Use for treasure chests so the new object is the highest thing |
| 404 |
* beneath the player, but not actually above it. Note - the |
| 405 |
* map and x,y coordinates for the object to be inserted must |
| 406 |
* match the originator. |
| 407 |
* INS_MAP_LOAD: disable lots of checkings done at insertion to |
| 408 |
* speed up map loading process, as we assume the ordering in |
| 409 |
* loaded map is correct. |
| 410 |
* |
| 411 |
* Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY |
| 412 |
* are mutually exclusive. The behaviour for passing more than one |
| 413 |
* should be considered undefined - while you may notice what happens |
| 414 |
* right now if you pass more than one, that could very well change |
| 415 |
* in future revisions of the code. |
