did this ever get added as an official library? its seems very good
Fourspriter saves the background before it draws a sprite on it, and then replaces this background to erase the sprite. This means you can use it with a background without worrying about the background being destroyed.
Like this: <!-- m --><a class="postlink" href="http://britlion.googlepages.com/Sprity.z80">http://britlion.googlepages.com/Sprity.z80</a><!-- m -->
(break in to the basic, if you dare! [The standard routines here aren't interrupt driven])
Yes, this is in the library just #include <fourspriter.bas> to get it - but the functions have been renamed and redescribed when Boriel did some rewrites in it. You should have a look at fourspriter.bas in the library directory where you installed zxb to get the usage; it's not well documented, and I think it's based on the oldest version of fourspriter.
