Commodore Amiga - Figure 4-8 Sprite Priority; Reusing Sprite DMA Channels

When you have more than one sprite on the screen, you may need to take into con-
sideration their relative video priority,
that is, which sprite appears in front of or behind
another. Each sprite has a
fixed video priority with respect to all the others. The
lowest numbered sprite has the highest priority and appears
in front of all other sprites;
the highest numbered sprite has the lowest priority. This is illustrated in figure 4-8.

Figure 4-8: Sprite Priority
Reusing Sprite DMA Channels
Each of the eight sprite DMA channels can produce more than one independently con-
trollable image. There may
be times when you want more than eight objects, or you
may be left with fewer than eight objects because you have attached some of the sprites
to produce more colors or larger objects or overlapped some to produce more complex
images. You can reuse each sprite·
DMA channel several times within the same display
field, as shown
in figure 4-9.
