- negative values have no meaning
- left in optional tile x/y for backwards compatibility

## `$00`−`$EF`: `anim_wait` *length*
## `$D0`: `anim_obj` *object*, *x1*, *x2*, *y1*, *y2*, *param*
The *x1*/*x2* and *y1*/*y2* pairs specify the position on screen of the animation object.
*x1*/*y1* specify a tile position, and *x2*/*y2* specify a pixel offset from that tile.
## `$D0`: `anim_obj` *object*, *x*, *y*, *param*
*Alternate*: `anim_obj` *object*, *x_tile*, *x*, *y_tile*, *y*, *param*
Values for *x2*/*y2* are in the 0-7 range, since 8 pixels make a tile.
Spawns an *object* at coordinate (*x*, *y*).
Values for *x1* are between -16 to 31. In practice *x1* starts between 0 to 15, then between -16 to -10. Negative values are relative to the opponent, while positive values are relative to the player. Useful values are between 14 to -10 (for the opponent) and between 0 to 13 (for the player).
*object*: `ANIM_OBJ` constants (see [constants/battle_anim_constants.asm](/constants/battle_anim_constants.asm))
*x*: the x position in pixels
*y*: the x 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.
Some sample values are:
*TODO: what happens for x/y values greater than 160/144 respectively?*
*TODO: useful positions*
*TODO: document each object*
- 0: player left border
- 6: player center
- -15: enemy center
- -10: enemy right border
Values for *y1* are also between -16 to 31; the useful range is between 2 to 14.
Values between 2 to 8 will be in the opponent's area (2 being the top border and 8 being the
bottom border), and values between 8 to 14 will be in the player's area (again, 8 being the top border and 14 being the bottom border).
The center of the body is often 2 to 4 tiles away from the border (i.e., 5-6 for the opponent or 10-11 for the player).
## `$D1`: `anim_1gfx` *gfx*
