For making graphical TI-BASIC games, I've always kept a 5x5 [tibd]textsprites[/tibd] finder that takes a sprite in the form of a matrix and finds characters whose leftmost columns help build the sprite. I made it back in 2009 or so, and it was nearly four hundred bytes, which for me back then was an achievement. Last year I figured I'd try fixing it up again and got it down to 308 bytes, but today I decided to try again and cut out half of that. So here's my 148-byte text sprite finder. It takes a matrix (in Ans) as input and outputs a string (in Ans), and destroys L1-L5 and I in the process. Here it is in TokenIDE format:Matr>list(Ans,L1,L2,L3,L4,L5
"?
For(I,1,5
Ans+sub(" .?X+çQB^SplotcrossJ|v[s][e]plotsquareTI:?^^x[xhat]CAY?^^2ZV5è[i]",32fPart(sum(expr(sub("L1L2L3L4L5",I,1))10^5-cumSum(binomcdf(4,0))))/32)+1,1
End
sub(Ans,2,5I know it could be modified to parse faster and not destroy the lists, but that made it larger and involved destroying [A], which I feel is more valuable than L1-L5.

Wow! That's crazy fast and crazy small. Thanks for the code! If I ever get around to finishing my DM utility I'll definitely use this. One question: how does it handle impossible text sprites?

Nice. I think there is only one impossible column though, unless you're counting sixth row ones too. I should probably go back and look over my text sprite maker and see if I can change anything. It's over a year old now and in the depth of the projects forum

Ah okay Well cool. I need to look at my sprite maker too. I never did add the things I wanted

I thought there was only 1 combination that didn't have a character equivalent?

I think they all have character equivalents, but not every available character equivalent is three pixels wide. That might break display in a program that assumes that width.

You're partly right. Every combination has one but there are two others that are more than three pixels wide. I think that's what he means.

I thought that was what I said. Which is, in retrospect, wrong, as I believe there's one combination without an equivalent. *headdesk*

true i suppose, although I would have included them, and then allowed people to remove them if they wanted to impose restrictions, as removing or excluding tokens is much easier than adding them in

Wow! That is really good. This will make textsprites much easier.
