Dear visitors and members, with the staff having moved on to other life interests and as a result of changes in people's internet usage habits, the CodeWalrus community have migrated almost entirely to Discord, IRC and WalrusIRC and is now essentially a place where to hang out, chat about gaming, programming, music, anime, and chill. As a result, even though the CW forums will remain open for posting, for faster TI, Casio or HP calculator help and news we recommend using the bilingual TI-Planet forums instead.

We encourage everyone to join our Discord server now.

* WalrusIRC

You need to have 5 posts and not be part of restricted usergroups in order to use the WalrusIRC embedded shoutbox. However, you can also access our IRC channel called #CodeWalrus via EFnet.

For Lionel...

I implemented your suggestions. The -Os switch did cause me some problems... specifically it made the DrawSelectScreen function very fragile. I had to add some defensive coding to get it working again; but still it seems like even minor change to the function would break it again. It is working now. The -Os switch also resulted in my Sleep function no longer delaying for the specified amount of milliseconds (it was getting optimized out)... this gave the appearance that Jumpman was 100% to 200% faster. I ended adding some asm("NOP") to ensure my delay loop would not get optimized.

I did not implement the inlines that you suggested. I did not realize the BSS section resulted in such unoptimized calls. Thanks for pointing that out.

Thank you for your suggestions to make Jumpman even better.

I also corrected a few minor bugs:
- enemy collision detection was intentionally disabled for testing purposes but was unintentionally included in the release.... whoops :-[
- tightened up the collision detection with bullets and collectables
- corrected the version string to v1.01

Update coming soon  ;D
