Hello everyone.

Please do not laugh your socks off, but I have a ridiculous problem.

Tell me why the screen turns blue when loading the sprite?
I would like the background to stay red.

Sprites automatically start up a system that clears the screen every frame. You can either tell it the new colour to use with the COLOR BACKDROP command, or use the SET SPRITE command to disable this screen clearing.

The command is:
SET SPRITE 1, x, 1

Where x can be one of the following values:
0 - No backsave
1 - Backsave & restore
2 - No backsave, clear to backdrop (this is the default)

Backsave is when the background is saved before drawing the sprite, you are then shown the fully updated display, then finally, the saved copy is drawn back - this basically makes the sprite a temporary part of the display, but it is slower.
