====== Special Macro 3D Objects ======

Special Macro objects are objects that are loaded into the level from the [[super_mario_64:level_commands#eload_collision|level script command 0x2E]]. Their main purpose is to save space in the ROM, since they only take up 8, 10, or 12 bytes each whereas regular objects take up 24 bytes. However, they are more limited than the regular objects loaded from the [[super_mario_64:level_commands#place_object|level script command 0x24]].

ROM Hacks of SM64 usually won't use special macro objects, since ROM space is not an issue.

----

===== Limitations =====

  * You can only directly modify the position, Y rotation, and the first two behavior parameters of the object.
  * They will always appear in every act in the level, as they don't have an act mask.
  * Each special macro object contains a preset ID, that references a list that tells the object what model ID and behavior are.

----

===== List Format =====

The level script command 0x2E loads a list of special macro objects during it's [[sm64:collision_data#collision_loading_routine|collision loading routine]]. The length of the object is determined by the Preset ID (see preset table entries below).

==== 8 byte object ====

''[<color goldenrod>ID ID</color>] [<color red>XX XX</color>] [<color green>YY YY</color>] [<color blue>ZZ ZZ</color>]''

| <color goldenrod>IDID</color> | Preset ID |
| <color red>XXXX</color> | X position of object (signed 16 bits) |
| <color green>YYYY</color> | Y position of object (signed 16 bits) |
| <color blue>ZZZZ</color> | Z position of object (signed 16 bits) |

==== 10 byte object ====

''[<color goldenrod>ID ID</color>] [<color red>XX XX</color>] [<color green>YY YY</color>] [<color blue>ZZ ZZ</color>] [<color magenta>RY RY</color>]''

| <color goldenrod>IDID</color> | Preset ID |
| <color red>XXXX</color> | X position of object (signed 16 bits) |
| <color green>YYYY</color> | Y position of object (signed 16 bits) |
| <color blue>ZZZZ</color> | Z position of object (signed 16 bits) |
| <color magenta>RYRY</color> | Y Rotation |

==== 12 byte object ====

''[<color goldenrod>ID ID</color>] [<color red>XX XX</color>] [<color green>YY YY</color>] [<color blue>ZZ ZZ</color>] [<color magenta>RY RY</color>] [<color cyan>B1</color>] [<color orange>B2</color>]''

| <color goldenrod>IDID</color> | Preset ID |
| <color red>XXXX</color> | X position of object (signed 16 bits) |
| <color green>YYYY</color> | Y position of object (signed 16 bits) |
| <color blue>ZZZZ</color> | Z position of object (signed 16 bits) |
| <color magenta>RYRY</color> | Y Rotation |
| <color cyan>B1</color> | Replaces B.Param 1 value if not zero |
| <color orange>B2</color> | Replaces B.Param 2 value if not zero |

===== Special Macro Preset Table =====

The Preset ID is used to get the Model ID, Behavior address, and the default Behavior parameters for the object. The location of this table differs based on the version of the game you are using.

^Version^ROM Address^
|North America (US)| 0xED350 |
|Europe| 0xBE100 |
|Japanese| 0xEC240 |
|Japanese (Shindou Edition)| 0xC98D0 |
|Chinese IQue| 0xCBD90 |


==== Entry Format ====

Each entry in the table takes up 8 bytes. The list ends when a preset ID of 255 (0xFF) is found.

''[<color lightgray>ID</color>] [<color cyan>B1</color>] [<color orange>B2</color>] [<color green>MM</color>] [<color red>BS BS BS BS</color>]''

| <color lightgray>ID</color> | Preset ID |
| <color cyan>B1</color> | Default B.Param 1 value |
| <color orange>B2</color> | Default B.Param 2 value |
| <color green>MM</color> | Model ID |
| <color red>BSBSBSBS</color> | Segment address of behavior |

==== Entries ====

Anything with a question mark (?) means that it is a guess, and needs to be verified.
