How do I set a sprite's home? SPHOME just makes it disappear.

You have to use SPHOME correctly. What I did was SPHOME 0,8,8. Too big a number=sprite centered around wrong area=sprite exiting field of view.

Remember that SPHOME works relative to a sprite's top left corner. Example: If your sprite's size is 16x16, you could use SPHOME <sprite number>,8,8 to set the sprite's home in its center.

So that's the problem, Zee. SPHOME refers to different coordinates!
