##### Need some help speed optimizing a routine
« on: June 13, 2011, 09:02:01 pm »
I've been working on a text routine for the ObjectStack for the Axe GUI Library, but it's incredibly slow.
I'm only so-so at optimizing, and that's mainly size optimizing, so I'm having some trouble speeding it up. Even at 15mHz speed, it's still slow for large chunks of text. If anyone could help me speed this up, it would be greatly appreciated.

Here is the routine in question:
Code: [Select]
:Lbl TEX:0→{L5}r:0→{L5+2}:r1→r4:For(r5,0,length(r3)):If {r3+r5}=1:{L5+2} xor 1→{L5+2}:End:If {r3+r5}=3:{L5} xor 1→{L5}:End:If {r3+r5}=2:{L5+1} xor 1→{L5+1}:End:If {r3+r5}>3:Pt-On(r1,r2,{r3+r5}*8+Pic1TX):If {L5+2}:ref(r1,r2,{{r3+r5}+Pic2TX},4):rref(r1,r2,{{r3+r5}+Pic2TX},4):For(θ,4,7):0→{L1+θ}:End:conj({r3+r5}*8+Pic1TX,L1,4):Pt-On(r1+1→r1,r2,L1):End:If {L5}:rref(r1-{L5+2},r2,{{r3+r5}+Pic2TX}+{L5+2},6):End:If {L5+1}:ref(r1-{L5+2},r2+6,{{r3+r5}+Pic2TX}+{L5+2},1):End:r1+{{r3+r5}+Pic2TX}→r1:End:If r1≥84:r4→r1:r2+6→r2:End:End:Normal:Return
Pic2TX is a list of the width of every small font character, Pic1TX is a compilation of sprites creating the full small font set.

Attached in the zip is: GUILIB3, the library with the routine in question; GUICML, the source for my library testing; ZGUITEXT, the library containing Pic1TX; ZGUITWID, the library containing Pic2TX; ZDROPMEN, Nemo's dropdown menu routine, slightly modified for my own devious purposes.

Again, any help is greatly appreciated, and would benefit anyone who would use the GUI Library once it's finished. Thank you in advance.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

Untested, but this should work I think:
Code: [Select]
:Lbl TEX:0→r5:r1→r4:While {r3}→r6:!If -1:r5 xor 1→r5:Else!If -1:r5 xor 2→r5:Else!If -1:r5 xor 4→r5:Else:Pt-On(r1,r2,r6*8+Pic1TX):If r5 and 1:ref(r1,r2,{r6+Pic2TX},4):rref(r1,r2,{r6+Pic2TX},4):conj(r6*8+Pic1TX,L1,4):0->{L1+4}r->{L1+6}r:Pt-On(r1+1→r1,r2,L1):End:If r5 and 2:rref(r1-(r5 and 1),r2,{r6+Pic2TX}+(r5 and 1),6):End:If r5 and 4:ref(r1-(r5 and 1),r2+6,{r6+Pic2TX}+(r5 and 1),1):End:r1+{r6+Pic2TX}→r1:End:If r1≥84:r4→r1:r2+6→r2:End:r3+1->r3:End:Normal:Return
