Learning to use OS_SpriteOp

Hello,

I’d like to learn how to use OS_SpriteOp. How would you suggest I go about doing this?
I’ve got the RISC OS 3 programmer’s reference manual PDFs.

The sorts of things I’d like to do with it would be to create sprites and modify them with a BASIC program, and save them to disk.

I may also want to ‘blit’ sprites into another sprite and then scale that sprite to fit the screen, as well as scale sprites and rotate them around a certain point.

PM

I first learned to use that mainly by reading other people’s code on Acorn User cover discs and some APDL discs, referring to the PRMs from then on once I was familiar with the basic syntax. There are a few old tutorials kicking around online.

http://www.tofla.iconbar.com/tofla/pubs/arc/index.htm Scroll down the index and there’s a 4 part tutorial on “Sprite Plotting”.

http://www.apdl.org.uk/riscworld/volumes/volume9/issue3/firstbasic/chap11.htm This one teaches bad habits because it’s using the system sprite area along with its specific star commands but…
http://www.apdl.org.uk/riscworld/volumes/volume9/issue4/firstbasic/chap14.htm …in this section they modify the above programme to use OS_SpriteOp.

Thanks for the info, I’m going to read these links and refer to the PRMs and get working on it and see what I can do.
