Title: ridiculously fast sprite routine by me
Post by: elfprince13 on May 25, 2006, 11:55:00 am

I just wrote a routine which can display 96 8*8 sprites in 20 seconds in pure Basic.  :P

Anybody interested in seeing it?

PLEASE O_O show at least a screenie? Is editing them easy though?

That's the whole screen... o.o
but how filled in are the sprites?

:D lemme copy it over to my computer.
And editing does require a little more though than your average sprite work--and the size can range from 5 bytes to 120 bytes--, but for 8*8, especially if you are converting them from another game anyway, it isn't too bad. And it should work nicely for 16*16's too, although I haven't tried it.

exactly. Ive toned it down to 77 (11 columns by 7 rows) to make it look prettier, and for a normal map (e.g. without every tile filled) it only takes about 7 seconds.

can you have 9x9 sprites and 10x10 sprites for example? thats the good thing I like with pure basic sprites

Ohh, I want to see it in action!

@xlibman: of course, its just the screen dimensions aren't nearly as nice for such things.

wow look nice I should try to mess with it asap

I dont mind the screen dimensions problems, some asm games werent even full screen :D in 10x10 you would only lose 3 pixel height and 5 pixel width with a 6x9 map

Wow, its fast!
So how do you make sprites for it? :)

First you try to see the lines (and individual pixels if you can find groups of 2) in the sprite, but without overlapping if possible.
Second you use a for loop to transform half the lines to the other half.

if you have one extra line or one extra pixel, stick that outside the loop.

if you have both, just put the line inside the loop, and make it so the start and endpoint are the same second time around.

 Did you achieve this on a TI-83+? Or, are we talking about the faster Z80 calcs (TI-83+SE, TI-84+, TI-84+SE)?

I'm just curious.  :)

84+SE. feel free to fiddle and come up with your own times, but 84+s have clocks which makes it easier.

does it means it doesnt work on 83+/SE? (assuming you talk abou t clocks)

 No, he is just saying when he was testing it he timed it useing the t states.

exactly. all the timing code has been removed.

oh I didnt though abou that, nice idea tho testing speed with clock :P

I do that with all my publicly released routines.
