Huge optimization thanks to Runner.

Using his LCDKIT Axiom, I can remove "+32".

That is 21 cycles removed per pixel shown. :D

(@ TIOS) Nope, the code is slightly larger.  But it isn't very noticeable.

The program is currently 1927 bytes.  which is only about 300 more than the source ;)

It runs smoother and quite a bit faster from last update.

Nice. Can you now also add new features or don't you want to do that?

Lol, my problem is getting a strong amount of time for only programming :P
I only get a few min here and there between homework, Karate, Pole-vault, and boyscouts.  (and trying to teach myself about rotating 3d ;) )

I think the first features i will add are new tile types, including an anti-gravity block.

Edit: here is the latest build  (and if someone can make a screeny, it would be appreciated.  I can't get wabbit to make the screeny smooth grey)

i did http://www.omnimaga.org/index.php?action=dlattach;topic=10657.0;attach=9799

I do it separately out of habit.   There used to be a bug where it would fail sometimes, and i didn't like rewriting things :P

and here is source if u want to look for optimizations.

Ok, I might actually be able to implement rotation in the game this game.  Haven't tried it out yet as i have to move some buffers around :/  but i will be working on it.

Anyone know a way i can do...
Data(768 0's)->GDB2
other than typing them in manually...

Woo!  Do you mean ground rotation?  If so, that would be great!

Ya I do,  Not sure if this will be the same game from start to finish ;)  Goals in it may change along the way.

I didn't realize that i wouldn't have to rotate the whole screen, just what the user could see.


Time to make some calculations for depth seen, then use that to determine how much of the screen should be rotated.



Also, about time for bed.  (to dream about Mariokart on calc)... (oh and dream about the Nspire's RSA keys to be factored)

I'm just curious.  How would you rotate the image?

here is the unoptimized version...
Code: [Select]
:For(X,0,95)
:For(Y,0,63)
:cos(A)->D
:sin(A)->E
:If pxl-Test(X,Y)^r
:Pxl-on((X*D-(Y*E)//128,Y8D+(X-16*E)//128)
:END:END:END



What I am planning to do about speed is only checking aprox, a 32*32 area.
If that is too little, i will change it to a 48*48 area, or change depth perception.
