Animation

Animations are accomplished using two additional separate data areas.

The Animation Data area contains 256 actual frame-by-frame color levels. To set these levels, the SET_ANIM_DATA_1, 2, 3, and 4 commands are used:

Command Name	Byte Format	Description
SET_ANIM_DATA_1	72 18 00 aa v1 00 00 00	aa is the address where v1 will be stored.
SET_ANIM_DATA_2	72 19 00 aa v1 v2 00 00	aa is the address where v1 will be stored; v2 will be stored at the following address.
SET_ANIM_DATA_3	72 1A 00 aa v1 v2 v3 00	aa is the address where v1 will be stored; v2 will be stored at the following address, and v3 after that.
SET_ANIM_DATA_4	72 1B 00 aa v1 v2 v3 v4	aa is the address where v1 will be stored; v2 will be stored at the following address, then v3, then v4.

The Animation Info area contains 64 animation slots, each of which determines the address of the animation loop within the Animation Data area, the number of frames in the loop, the offset to the first frame (relative to the address), and the duration of each frame. An animation slot is set using the SET_ANIM_INFO command:

Command Name	Byte Format	Description
SET_ANIM_INFO	72 17 00 ss aa ll oo dd	ss is the slot number. aa is the address. ll is the number of frames. oo is the offset of frame 1. dd is the duration of a frame.

The duration of a frame is expressed in hundredths of a second; the longest possible duration is 2.55 seconds.
