root42Neato: my Snake game now also runs on 8K PETs. You can trim down printf so that it doesn't support float or long types, which we don't need. This frees up a lot of code, so the .prg is now 3.1K in size!<a href="https://codeberg.org/root42/letscode-cbm-pet-snake/commit/dbaa169b7dc6b8ddf0e4a66efaaa81ed0919f665" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://codeberg.org/root42/letscode-cbm-pet-snake/commit/dbaa169b7dc6b8ddf0e4a66efaaa81ed0919f665</a><a href="https://chaos.social/tags/letscode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#letscode</a> <a href="https://chaos.social/tags/commodore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commodore</a> <a href="https://chaos.social/tags/commodorePET" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commodorePET</a>

root42New video: Let's Code Commodore PET 0x02: Snakes on a PETIn this episode we code a simple game for the PET. It is the classic snake game, where you control a snake that picks up food and grows longer. We learn how to read from the keyboard, and how to limit the speed of the game, as the PET is slow, but not THAT slow.<a href="https://youtu.be/UxZhvHx9nsY" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://youtu.be/UxZhvHx9nsY</a><a href="https://chaos.social/tags/commodore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commodore</a> <a href="https://chaos.social/tags/commodorePET" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commodorePET</a> <a href="https://chaos.social/tags/letscode" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#letscode</a> <a href="https://chaos.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a>
