that too, altough on home screen it take 3 chars slots

o.o

where did my reply go.....you can use the % to actually perform % operations in TI-Basic (assuming Symbolic ISNT installed)

Or you can dl and use http://www.ticalc.org/archives/files/fileinfo/384/38404.html

this may be late but...

when/if you use the homescreen for a graphical game without "smooth" scrolling. you can convert what you would output into a string and then use that as an almost screen buffer. if you do this it actually will shorten your code. all you do it redraw the string before you update the position. Well im not sure if it will shorten everyone's code but it defenitely shortened my perhaps unoptimized code a few bytes. plus you can use sub(str,(a-1)*16+B) as hit detection, i think its faster than matrix hit detection.

Edit by Netham45: part of your code was showing up as a smiley.

there is no post time limit on this topic, as it's a trick topic and its pinned

I use that in my Harrierfalcon Contest entry (sort of).

That was used in tifreak's RPGSK and I'm using it in WoM.
I didn't think it was a 'trick' more than common knowledge...

Here's a trick I'd like to see done efficiently:
Using IS>() or DS<() to exit some kind of loop

Yeah, but that causes memory leaks.

I did not know this until today

If you make something like the other basic game, you can now draw circles faster!

Circle(X,Y,R,{i

R=radius, X=x coord. Y= y coord..

Thanks kalan for posting this. This draws circles 3 times faster

I want to find the writer of the TI-OS and personally tell him how random of a feature that Fast Circle routine is.
It's been there all this time and no one ever knew... We knew there was a routine deep in the OS to do it, but no way to call it outside ASM...
That find really inspires me. There's so much to calcs that we still don't know...

dinhotheone · « **Reply #57 on:** July 19, 2007, 04:26:00 pm »

there doesnt happen to be a way to draw white circles is there? also, fast circle seems...not dumb but why wouldnt you want to draw circles 3x as fast everytime? is it crappyer resolution or something?

DJ Omnimaga · « **Reply #58 on:** July 19, 2007, 04:59:00 pm »

i barely see any difference in them. I think its slightly lower quality and they wanted the people in math to view the circle build slowly so they made them slower

I saw it on UTI, and it is amazing! But that faster way would be to calculate the circle points and draw...
