/me thinks you will like my new sprite routine which is blazing fast. it requires more work to make the sprites, but is much faster than hex sprites. :-p

Gonna make a tutorial on it?? lol

I will post it here if you want.

Its incredibly fast, Im going to be using it for an Turn Based Strategy game that rerenders the map every time you scroll

I just timed it, and it rendered 96 8*8 sprites in 20 seconds with no optimizations on the drawing loop.

WTF! That's pwny.

and it averages around 110 bytes per sprite.

My guess is it would be even faster to render with 16*16, since thats a quarter the number of tiles on a map, while still using a fairly small bit of code.

35ish lines of code gets you a ship, a plane, a city, a tank, and a truck.

actually making the sprites is as follows:

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.

Have you tried that out on an actual calculator?

thats what I wrote it on. and no, I didn't enhance the screenshot.

Yes, you showed me this before. And I have used the same technique before, but never got the resaults. The only question is. are these very reliable sprites? Can one move them around with out having to reset the screen all the time?

yup. the speed is the secret of this routine. and it lies in the fact that every monchrome sprite can be divided up into lines. and the total number of lines will always be a multiple of 2, or a multiple of 2 +1.

This means a For() loop can be used to dramatically reduce code, and thus the amount of time the parser has to spend skipping lines looking for :End

so how exactly does this work. because it would be awsome if i could program sprites that fast.

see my tile mapping routine (its in this subforum). It should convert easily to 83 basic.

Ah yes, I used this method for sprites in a few of my programs. Nice work.

you realise how old this right? see the newer topic...

Oh, I thought you had resurrected this topic to announce that new project of yours. My mistake.

nope, thats an entirely new project
