My list of things to do? -Bump this months post amount to over 10 000 -Figure out a bunch of algorithms in assembly for math and drawing -add more drawing functions to BatLib -Add a menu system to BatLib (so that you can use PopUp in BASIC... inspired by my 89t) -Boost UTI up -Answer program requests -Finish my french and math homework -Maintain a 3.5 GPA at least -remember to eat on time -Do my laundry -Clean my room -Go to club meetings -Learn Axe -Work on BASIC ReCode -Go to classe And probably other random things I am missing
Hey all you BASIC programmers out there (and occasional Axer)! I have something that YOU might like. You know those amazing little creatures? Those hex opcodes? Well guess what?! I've got em
Here is a small PDF that I have been working on that has a mild sample of about 40 hex opcodes. If anybody has cool suggestions, lemme know and I'll see what I can conjure up!
Yeah... Originally it was called FontEdit, then I got to command 13 which was for tilemaps and I decided to rename it SpriteLib. Then it got to about command 42 before I changed it to BatLib. It is still centered around graphics and math, but the math part is only starting to make its presence known.
I haven't gotten to say hello! ... Hi! And sorry if it was over on UTI or TIBD... I try to answer questions there :'( But, um, hi! It is quite active here, so you will get stuff answered pretty easily.
"peanuts" is a weird word, so I will refrain from showing off my peanuts.

Hmm, It uses temp RAM, too, which might be a problem (fixable) in Knight OS, but yes, I could add a snippet of code to let HL be a pointer to the buffer. HL would immediately be copied to temp RAM, but it would be much easier to work with, you're right.
Ah, let me check which version of that routine I uploaded. One used a pointer stored in a temporary RAM address and the other just used plotSScreen. I forgot Scout's tool converted to decimal, not hex. Oh, and I'm working on more ideas
