Ah, okay. That would make my inserted line "A*8-I->G" then.

Here's the fastest code I could come up with. It uses optimized loop structures and even more pre-calculation.

Also, did you mean to use B as the y value in your code squidgetx? Because looping from 0-11 wouldn't make much sense for y, so I changed it. :P

Code: (Code) [Select]
Y and ᴇF8*2+(X/2/2/2)+L₁→D
⁻(X^8)→I
⁻(Y^8)→J
12→B
Lbl LB
  64
  Lbl LA
    →A
    If {*2+B+D}
      →C
      Pt-On(B*8+I,A+J,C*8+Pic0)
    End
  If A
    -8
    Goto LA
  End
If {°B-1}ʳ
  -256→{°B-1}ʳ
  Goto LB
End

   
Code: (Comments) [Select]
Tilemap offset; optimized version of Y/8*16+(X/8)+L₁→D
X offset;
Y offset
For(B,12,0,⁻1)

For(A,64,0,⁻8)


If tile != 0
Store tile value
Display tile

Second part of For(A) loop



Second part of For(B) loop
Utilizes the fact that the second byte of A is 0 and -256 is faster than -1

:crazy: That's amazing, Runer. Do you always come up with code like this? :P

I am so familiar with using optimized loops that I pretty much automatically come up with maximally optimized loops. ;) The rest of the stuff, though, just takes a bit of thinking and comparing potential command sizes/speeds. This file I assembled a while ago actually helps a good deal when assessing options.

Pretty much the Axe opt trick. Everything else builds on it :D

That's going be a thing of the past.  That optimization is built into Axe now. ;)

woah, that's mad nice, Runer. Is it always better to avoid For() loops and use Lbl/Goto structures instead (or the While -1 structure)?
 
Quigibo, do you mean that something like
Code: [Select]
A-1->A
!If A
...would be auto-opted to
Code: [Select]
A-1->A
!If
...

If so that'd be awesome. And maybe if a loop starts with While A or Repeat A, move the A to the end of the loop too?

Wow thats going to be auto optimized now?  Thats gotta shave lots of bytes off of every program O.O

To take advantage of it, you'd still have to code in the same way, I think. But actually typing the variable name makes much more readable code :)

Quigibo, how is this being optomised?  Is it actually looking into the assembly and seeing when there is a Ld ($) HL followed by a LD HL ($) ? or something along those lines?
