- It depends on how much each picture differs from the previous. When your
- camera approaches the table, large parts of the pictures change each frame,
- and large amounts of memory have to be transferred which slows down animation
- speed. There are some ways to avoid this problem:
-
- - Don't use much (or any) dithering with the objects that change their
- position every frame. (When you move your camera, every object "changes"
- its position)
- - Try to use a smaller color resolution (e.g. 16 instead of 32 colors)
- - Don't move the camera (not very helpful in your case :-), only objects.
-
- In general: keep the screen areas with changes from frame to frame as small
- as possible, try to have big areas where nothing happens.
