/* These are flags passed to insert_ob_in_map and |
933 |
* insert_ob_in_ob. Note that all flags may not be meaningful |
934 |
* for both functions. |
935 |
* Most are fairly explanatory: |
936 |
* INS_NO_MERGE: don't try to merge inserted object with ones alrady |
937 |
* on space. |
938 |
* INS_ABOVE_FLOOR_ONLY: Put object immediatly above the floor. |
939 |
* INS_NO_WALK_ON: Don't call check_walk_on against the |
940 |
* originator - saves cpu time if you know the inserted object |
941 |
* is not meaningful in terms of having an effect. |
942 |
* INS_ON_TOP: Always put object on top. Generally only needed when loading |
943 |
* files from disk and ordering needs to be preserved. |
944 |
* INS_BELOW_ORIGINATOR: Insert new object immediately below originator - |
945 |
* Use for treasure chests so the new object is the highest thing |
946 |
* beneath the player, but not actually above it. Note - the |
947 |
* map and x,y coordinates for the object to be inserted must |
948 |
* match the originator. |
949 |
* |
950 |
* Note that INS_BELOW_ORIGINATOR, INS_ON_TOP, INS_ABOVE_FLOOR_ONLY |
951 |
* are mutually exclusive. The behaviour for passing more than one |
952 |
* should be considered undefined - while you may notice what happens |
953 |
* right now if you pass more than one, that could very well change |
954 |
* in future revisions of the code. |
