I know you said no essay necessary on IM, but I think this situation is deserving of at last more than a simple "I'm sorry guys."

I am Radical Pi. I was once active in the community, quite a few years ago. I don't see many old faces around, but a few of you I do vaguely recognize. You probably don't want to hear my life story, so I'll just give the important parts. Once upon a time I was an Omnimaga staff member, with a featured project or two. But like so many people back then, I was plagued by ambition and overhype. Ultimately, I left the community in pursuit of other ambitions (which also ended up failing, but nevermind that).

Last Saturday, DJ Omni contacted me over AIM and told me about how the community (both Omnimaga and the TI programming community at large) were thriving. New projects that were actually finishing, the Nspire being hacked, even a new language for the 83+ series. I was intrigued, but still ashamed of my old non-committed self. So, I hatched a plan to come back, but under a new name: Nyrax.

When making this account I did see the board rule about there being only one account per person. But, since the rule mentioned that it was to prevent ban/ignore-list dodging, I figured I could take the risk in coming back this way. Obviously I was wrong to so blatantly disrespect this rule, but I was too thrilled by the fact that I was actually coming back to the first forum I ever really called my home forum. I tried to be as productive a new member as I could be, not only to inspire others, but myself as well.

And then I was found out. You can guess what happened between then and now.

By explaining myself above, I'm not looking for justification. I'm not looking for redemption. Not even sympathy. Just understanding, so you can judge my actions for yourselves.

I sincerely apologize for my misconduct. In retrospect, this really was a terrible idea from the beginning. At the very least, now I'm back and I've learned a valuable lesson from all this. Hopefully people will learn from my example, that disregarding the rules, even if you think it won't cause any harm, should never be done.

I had no idea that Omnimaga had recently been through a wave of incidents like this. Of course that one-account rule must have been there for a reason, but I never thought about what that reason might be.

I know that I was wrong to do this, and I'm glad I'm being offered this second chance. I swear, I won't mess it up.

The moral of the story? Obey the rules, never assume that you'll be the exception, deception is bad, all of the above; take your pick.

Welcome to omnimaga! *gives you some peanuts*

How much TI-BASIC do you already know?

You don't even need C. Take the substring at AW-W+B like so:

PROGRAM:CNVRTSP
ClrDraw
AxesOff
FnOff
Input "WIDTH: ",W
Input "HEIGHT: ",H
Input "SPACE CHARACTER:",Str2
For(A,1,H
For(B,1,W
If sub(Str1,AW-W+B,1)≠Str2
Pxl-On(A-1,B-1
End
End
StorePic Pic1

Pt is (X,Y), like how normal points are written.
Pxl is (Y,X) like Output( is for the homescreen.

It would help to know what the variables represent (although I have a good idea already ) and what the strings are.

I wouldn't mind taking a look at your code. I could always use the practice

No guarantees that I'll be that significant of a help though.

meishe91: I guess something like this... Imagine you're storing your 8x16 map in a matrix. That's 1163 bytes, but it can hold a huge amount of different possible tiles in any space (How many digits of accuracy can you get on a number? Yeah, a lot), but you probably won't be using that many different kinds of tiles. So consider a string, length 8x16=128 = 139 bytes. That string can have up to (however many different characters you can access) different tiles.
None of that really matters for 8x16 maps, because all the possible ways to store it are still simple and small. But what about, say, a 50x50 map? What's the most efficient way of storing that? And what's the fastest way of accessing it during the program, if it's different than how it's stored?
See what I'm saying?

I think it's good; it portrays its message in a way that will definitely get your attention.
