Have you looked at Calc84 raycaster library? Included in his Spooky Maze program.

That has got to be a record. World record, possibly. ;)

Syntax errors are easy, aren't they? Semantic errors, OTOH, is hard. I'll look at it later. Thanks for posting the source code in easily readable colors!

Don't you need comma for INC/DEC?

This was a fun week. Now to get back into heavy action next week.

Pretty colored boxes. Instant artwork demo. Or maybe dungeon room generator (hint :p )

What line number? It's a screen cap, so I don't think the error would be on my end. I need to keep working on this to make Rogue-like game. I'll post the code when that's done.

You need to change the sprite per direction, manually. Try using SPCHR.

This is actually an Artwork Demo of Colored Boxes. Hey, with a little mod, it'll work as dungeon room generator! :D HTH

You're doing a lookahead, right? 1.Set room origin and dimension randomly. 2. Use chkchr to see if it's free. 3. If not, reduce dimension, repeat from 2 until too small. 4. If too small, try again from step 1 until MaxN tries. Goto 7. 5. Draw room. 6. Repeat from 1 until MaxN tries. 7. Done. Something like that?

Flashlight program. You know, those 3DS screens are really bright! Fun with RGB command.

You can check out the real Flashlight app in e-store! I took heavy shortcut, obviously, but the disco light is still there!

You don't need to be super smart to do QSP. If it doesn't fit, lower the standard! Here is the Flashlight App in QSP! This little known gem has four modes (use touchscreen): Off, Flashlight, Emergency Strobe, and DISCO!

Looks complicated, especially with that kind of formatting. Can you show a screen grab of the game in action?

String Copy bug. Trying to copy string with = operator results in both strings being referenced the same way, instead of copied. There's a workaround, but I hate to have to do that everytime.

I think it's Reference vs Copy technique. It should be Copy all the time.

Something like this. And I seem to run into a bug!

If I really want to save space, I'd use simple string. T$="0123456789ABCDE ", and index it T$[Y×4+X]. It's great that you check for winning condition. I can't do that because shuffling is optional, and the puzzle begins in solved state. BTW, that 600 bytes limit is an early Apple Macintosh reference. :)

Excellent! A few observations: RANDOMIZE 0 is not needed. IF S will work fine. FALSE is 0. TRUE is non-zero. <>= operators are optional. Try using BUTTON(N) where N is 0-3. Default is zero, but that leads to overflow. I regularly use BUTTON(3) to prevent overflow. Excellent work! I appreciate it!

And that's how it looks. Must resist playing... Resist... Resist... Oh, what the heck. Just 5 more minutes. ^_^;
