Aaaah ok. Well if these commands are ignored on the 83 I guess it's fine, since then the game would still run on them, just slower ^^

Btw Quigibo told me there would be another method for my pixelation animations, but apparently it's much more complicated to perform, for my current Axe skills. He is still trying to figure out how to do it, but it would involve manipulating the screen RAM directly.

For now I think I'll stick to my current methods tho XD

Quigibo, I have a question. Currently, when you store to an address, the value of the expression becomes the address. Is this behavior ever planned to change, or can I safely use it for optimization?

umm... do you mean the value of the address becomes the expression?  I think the other way around is the expected behavior, no?

I'm pretty confident this won't change.  I know that I might in the future add something to store 16 bit numbers into 2 consecutive bytes, but I think that will use a different syntax anyway.

I meant that if you do 1->{L6}, the result (to be used by further operations) will be L6.

That's what I thought.  So yes, you can use that optimization.  So you can do things like 2->{1->{L6}+1} but the code can get pretty crazy looking really fast.

Also, I made an implementation of the Collatz Conjecture, inspired by a recent XKCD comic:
Code: [Select]
:9001->A
:Disp A>Dec,i
:Repeat A=1 or getKey
:If A^2
:A*3+1->A
:Else
:A/2->A
:End
:Disp A>Dec,i
:End

Another XKCD fan!  :)   I read it regularly as well.

Another thing, Quigibo, I think you should note somewhere in your documentation that operations are evaluated left-to-right. Also, some of the example expressions in your optimization guide assume full order of operations.

I don't follow XKCD much because I tried in the past and english as a second language prevented to get most of the jokes :(

The only ones I get are some of the 4chan memes references :(

I can get most jokes. I need to see again some to understand later (like the Rickroll one)

I don't follow xkcd closely but sometimes I see at random.

btw this is what calcmaniac referred http://xkcd.com/710/

Ok i have just finished my all new and super special awesome smoothscrolling tilemapper.  It supports scrolling anywhere from 1 to 8 pixels at a time, and could be expanded for vertical scrolling with not too much difficulty.  It uses the scrolling commands and then fills in the empty spaces made with new sprites.

Lol nice and fast, and if you scroll way too far, then you no longer need a pixel artist to draw 8x8 monsters, or even some tiles in particular for a RPG/adventure game, as they'll be generated for you :P

Also I didn,t knew you could do

[FFFFFFFFFFFFFFFF
F0F0F0F0F0F0F0F0]->Str1

instead of
[FFFFFFFFFFFFFFFF->Str1
[F0F0F0F0F0F0F0F0

Is it the exact same thing?
