Some notes about this test program:
  • It uses a 32x32 tilemap, with each tile being 1 byte. For testing purposes, the value of each tile is the sum of its x and y positions in the tilemap.
  • For testing purposes, each tile is an 8x8 tile displaying its base-10 tile number with the left half (tens digit) inverted.
  • Arrow keys to scroll, CLEAR to quit.

EDIT: By the way, sorry if the lowercase comments don't look right. I wrote this program with TI's Program Editor, which turns any lowercase letters that are also statistics variables into those special tokens instead of just treating them as lowercase letter tokens.

I didn't comment it much, but hopefully it's still understandable. If not, just ask me about it.

:!Ifθ+1→θ-10
:→θ

so... if, after being incremented, θ=10 then 1→θ?

runer, your optimisation is incredible.

EDIT: i just realised that i've been storing data to GDB1 or whatever, using another variable as the offset, and then calling GDB1 plus the variable (habit carried over from BASIC) when this whole time i could have just stored GDB1 to the variable initially. see, i'm learning already ;D

DOUBLE EDIT:0→θ, eh? so answer isn't carried from if statements. i should really learn the syntax BEFORE messing around with a code.

Increment θ, and then if it equals θ=10, then 0→θ :P

Darn, I think you should maybe put this (and the sprite editor that came out a while ago) in the downloads section, that really could be useful in the future, and it might get lost in the Axe sub-forum. Nice job! :)

This isn't a project or anything, I just whipped this up as an example in all of 30 minutes or something. :P

Wow, you're source is wonderful.  I like the optimizations... wow... ;D
I must learn to code like you in Axe! >:D

I wonder if this can be modified to scroll in arbitrary distances... (up to 8 pixels of course)

The answer is carried from if statements, but that was an !If statement which activates when the expression following it equals zero, so zero carries to the next line.

I've been debating making a super-optimization guide for Axe. Should I?

Please do. :)  I'd love to learn to coding like this. :)

I've deduced that scrolling more that 1 pixel per frame means that you would have to display more than 1 column of sprites per scroll, so it would be slower for sure, but i don't think the speed difference would be that large hopefully.
