Mine

MIENCR4F7 IN TI-BASIC W0000T!!!11

J/k, I wish :P It's actually Minesweeper, but with flood-fill and everything! :D

http://img.removedfromgame.com/imgs/mine.gif

That's full speed on a TI-84 Plus, so you can tell that the flood-filling is a bit slow. I'm still trying to improve it, but the code's about as optimized as I can get it right now O.O

Multiple levels coming soon. It's actually fully implemented; all I need to do is add a menu.

Looks pretty good for a ti-basic. A lot better than my version, which is very dumb. I like the white on black.

What sort of fields should I use for medium/hard mode? The mode in the screenshot is Windows-classic Beginner (9x9 board with 10 mines), but their Intermediate and Expert modes (16x16 and 30x16) don't exactly fit on a calculator screen :P

Each square is 5x5 with a border of one between any two rows/columns.

So with that, 16*10 is the max size?

Your description implies you aren't randomly generating new boards. Why not?

Just some ideas but you should make the mines/ bombs into creepers XD

I am; I'm just trying to decide what board sizes to use for the other difficulty levels.

Cool!  What kind of flood fill algorithm are you using?  Often times the difference in speed is not due to optimization, but algorithm :D

Yeah, I know why it's slow, and it's because my algorithm is pretty bad :/ Here's my flood-fill code:
Quote from: TI-BASIC
{~1.01,~.01,.99,~1,1,~.99,.01,1.01->L3
DelVar I{A+sub(B->L2
Repeat I=dim(L2
I+1->I
L2(Ans
F+pxl-Test(600fPart(Ans)+2,6iPart(Ans)+2->F
sum(seq(max(L1=L2(I)+L3(J)),J,1,8
If Ans
Then
" "+sub("12345678",Ans,1)+" 
Else
For(J,1,8)
L2(I)+L3(J
If Ans>=0 and iPart(Ans)<C and |E2fPart(Ans)<D and prod(L2-Ans
Ans->L2(1+dim(L2
End
"     
End
Text(600fPart(L2(I))+1,6iPart(L2(I))+2,Ans
End
The stuff between lines 11 and 15 are what's really slowing the thing down. It goes through the eight surrounding pixels and individually tests them to see if they're valid or not, and if so they get appended to the queue (L2). Because it has to do this for every element on the queue that doesn't have any mines surrounding it, blank squares take a while to show up.

I tried to implement the third algorithm on the Wikipedia article, but since there are eight directions in Minesweeper and three classes of elements (blank, numbered, mine), it turned out to be even slower than the one I have.
