FAST SRITES
by
Mark Robin
COMMODORE POWER/PLAY MAGAZINE
June/July, 1986
p.62
This small utility adds commands to
BASIC that allow you to move sprites
16 times faster than normal-- without
PEEKS or POKES. The syntax of the
new commands is:
* 1 A
^ ^ ^
asterisk sprite# direction
For example, the command to move
sprite number #1 up one position
would be: *1A. (There are 16
possible directions for the sprite to
move, labeled from A to P. The
Commodore Magazine article has a
table of directions.)
You may use more than one command
in a row. For example:
*1A*2E*3F84A
And if you use an IF-THEN statement,
a colon must come after THEN. For
example, if you wanted to move sprite
#1 up if variable A is equal to five,
the command would read:
IF A=5 THEN:*1A
To use fast sprites in your own
programs, write your own program
between lines 97 and 1000 of FAST
SPRITES. If you want to see what fast
sprites look like, you can run FAST
SPRITES and look at the demo.
