We just added space for maps to define 17 total `object_event`s. (Plu Let's look at how it works. `wMapObjects` is an array of `map_object` structs, one for each possible object (including the player). You can see what data is stored for each `map_object` in the macro definition in [macros/wram.asm](../blob/master/macros/wram.asm): ```asm -map_object: MACRO -\1ObjectStructID:: db -\1ObjectSprite:: db -\1ObjectYCoord:: db -\1ObjectXCoord:: db -\1ObjectMovement:: db -\1ObjectRadius:: db -\1ObjectHour:: db -\1ObjectTimeOfDay:: db -\1ObjectColor:: db -\1ObjectRange:: db -\1ObjectScript:: dw -\1ObjectEventFlag:: dw + map_object: MACRO + \1ObjectStructID:: db + \1ObjectSprite:: db + \1ObjectYCoord:: db + \1ObjectXCoord:: db + \1ObjectMovement:: db + \1ObjectRadius:: db + \1ObjectHour:: db + \1ObjectTimeOfDay:: db + \1ObjectColor:: db + \1ObjectRange:: db + \1ObjectScript:: dw + \1ObjectEventFlag:: dw ds 2 -ENDM + ENDM ``` This is all the same data that gets declared by the `object_event` macro, defined in [macros/scripts/maps.asm](../blob/master/macros/scripts/maps.asm): ```asm -object_event: MACRO -;\1: x: left to right, starts at 0 -;\2: y: top to bottom, starts at 0 -;\3: sprite: a SPRITE_* constant -;\4: movement function: a SPRITEMOVEDATA_* constant -;\5, \6: movement radius: x, y -;\7, \8: hour limits: h1, h2 (0-23) -; * if h1 < h2, the object_event will only appear from h1 to h2 -; * if h1 > h2, the object_event will not appear from h2 to h1 -; * if h1 == h2, the object_event will always appear -; * if h1 == -1, h2 is treated as a time-of-day value: -; a combo of MORN, DAY, and/or NITE, or -1 to always appear -;\9: color: a PAL_NPC_* constant, or 0 for sprite default -;\10: function: a OBJECTTYPE_* constant -;\11: sight range: applies to OBJECTTYPE_TRAINER -;\12: script pointer -;\13: event flag: an EVENT_* constant, or -1 to always appear + object_event: MACRO + ;\1: x: left to right, starts at 0 + ;\2: y: top to bottom, starts at 0 + ;\3: sprite: a SPRITE_* constant + ;\4: movement function: a SPRITEMOVEDATA_* constant + ;\5, \6: movement radius: x, y + ;\7, \8: hour limits: h1, h2 (0-23) + ; * if h1 < h2, the object_event will only appear from h1 to h2 + ; * if h1 > h2, the object_event will not appear from h2 to h1 + ; * if h1 == h2, the object_event will always appear + ; * if h1 == -1, h2 is treated as a time-of-day value: + ; a combo of MORN, DAY, and/or NITE, or -1 to always appear + ;\9: color: a PAL_NPC_* constant, or 0 for sprite default + ;\<10>: function: a OBJECTTYPE_* constant + ;\<11>: sight range: applies to OBJECTTYPE_TRAINER + ;\<12>: script pointer + ;\<13>: event flag: an EVENT_* constant, or -1 to always appear db \3, \2 + 4, \1 + 4, \4 dn \6, \5 db \7, \8 - shift - dn \8, \9 - shift - db \9 - shift - dw \9 - shift - dw \9 -ENDM + dn \9, \<10> + db \<11> + dw \<12>, \<13> + ; the dummy PlayerObjectTemplate object_event has no def_object_events + if DEF(_NUM_OBJECT_EVENTS) + {_NUM_OBJECT_EVENTS} = {_NUM_OBJECT_EVENTS} + 1 + endc + ENDM ``` `wObjectMasks` is likewise an array of mask bytes, one for each possible object.
