# Battle Animation Commands
|
||
|
||
Defined in [macros/scripts/battle_anims.asm](/macros/scripts/battle_anims.asm) and [engine/battle_anims/anim_commands.asm:BattleAnimCommands](/engine/battle_anims/anim_commands.asm).
|
||
|
||
|
||
## `$00`−`$CF`: `anim_wait` *length*
|
||
|
||
- *length*: duration in frames
|
||
|
||
|
||
## `$D0`: `anim_obj` *object*, *x*, *y*, *param*
|
||
|
||
***Alternate*: `anim_obj` *object*, *x_tile*, *x*, *y_tile*, *y*, *param***
|
||
|
||
Spawns an *object* at coordinate (*x*, *y*).
|
||
|
||
- *object*: `ANIM_OBJ` constants (see [constants/battle_anim_constants.asm](/constants/battle_anim_constants.asm))
|
||
- *x*: the x position in pixels
|
||
- *y*: the y position in pixels
|
||
- *x_tile*: an added x position in tiles (8 pixels)
|
||
- *y_tile*: an added y position in tiles (8 pixels)
|
||
- *param*: modifies the behavior of *object*. The meaning differs for each object.
|
||
|
||
The y position also depends on the y offset defined by the object.
|
||
|
||
- *TODO: what happens for x/y values greater than 160/144 respectively? Is it 1:1 with screen coordinates?*
|
||
- *TODO: how are the x/y values mirrored when the opponent is attacking?*
|
||
- *TODO: useful positions*
|
||
- *TODO: document each object*
|
||
|
||
|
||
## `$D1`: `anim_1gfx` *gfx*
|
||
|
||
## `$D2`: `anim_2gfx` *gfx1*, *gfx2*
|
||
|
||
## `$D3`: `anim_3gfx` *gfx1*, *gfx2*, *gfx3*
|
||
|
||
## `$D4`: `anim_4gfx` *gfx1*, *gfx2*, *gfx3*, *gfx4*
|
||
|
||
## `$D5`: `anim_5gfx` *gfx1*, *gfx2*, *gfx3*, *gfx4*, *gfx5*
|
||
|
||
Loads 1-5 sets of graphics. Will overwrite any previously loaded sets.
|
||
|
||
- *gfx*: `ANIM_GFX` constants (see [constants/battle_anim_constants.asm](/constants/battle_anim_constants.asm))
|
||
|
||
|
||
## `$D6`: `anim_incobj` *object_id*
|
||
|
||
Increments an object's state.
|
||
|
||
- *object_id*: the nth object in order of creation
|
||
|
||
Objects are state machines. `anim_incobj` progresses the state of an object.
|
||
|
||
## `$D7`: `anim_setobj` *object_id*, *state*
|
||
|
||
Sets an object's state to a specific value.
|
||
|
||
- *object_id*: the nth object in order of creation
|
||
- *state*: the state index
|
||
|
||
Objects are state machines. `anim_setobj` changes the state of an object.
|
||
|
||
## `$D8`: `anim_incbgeffect` *bg_effect*
|
||
|
||
Increments a bg effect's state.
|
||
|
||
- *bg_effect*: `ANIM_BG` constants (see [constants/battle_anim_constants.asm](/constants/battle_anim_constants.asm))
|
||
|
||
Since there can't be two of the same bg effect, the effect type is used. This is distinct from `anim_incobj`.
|
||
|
||
|
||
## `$D9`: `anim_enemyfeetobj`
