Menu in non-graphical homebrew?

Is it possible to make a menu in a non-graphical homebrew using printf()? Also, is it possible to create an option menu using the same method? e.g. If I wanted the user to pick a number between 1 and 10, rather than seeing all the options at one time, they could just use left and right on d-pad to switch between numbers. Thanks in advance! :P

Yes. Google ANSI escape sequences.

Thanks! :) But, if possible, could I have an example or a link to one?

This is really far too basic and generally applicable to be discussed in the Coding section of our forum.

Whoops, I'm pretty new to this so I didn't know. Sorry.

Plz help!!!! :/

Here's a simple example, that should work I think for what you want.

int nSelected = 0;
int tracker = 1;
int nTotal = 3; //number of options

for(;;){
WPAD_ScanPads();

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_A)
break;

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_RIGHT)
tracker++;

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_LEFT)
tracker--;

if(tracker < 1)
tracker = 1;

if(tracker > nTotal)
tracker = nTotal;

if(tracker == 1)
nSelected = 1;

if(tracker == 2)
nSelected = 2;

if(tracker == 3)
nSelected = 3;

printf("Choice: %d", nSelected);
}

(This code is modified from some Arikado gave me a while ago for one of the early versions of dop-IOS MOD)

Obviously you'd have to add more to this to make it 1-10, as it is, it's 1-3.

EDIT: Actually, this may work, with a fair bit less code:

int nSelected = 0;
int tracker = 1;
int nTotal = 10; //number of options

for(;;){
WPAD_ScanPads();

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_A)
break;

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_RIGHT)
tracker++;

if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_LEFT)
tracker--;

if(tracker < 1)
tracker = 1;

if(tracker > nTotal)
tracker = nTotal;

nSelected = tracker

printf("Choice: %d", nSelected);
}

Pressing A will select the number displayed, and it will be stored in "nSelected".
This version will only work if you want consecutive numbers (or at least numbers in a pattern, like increasing by three). With the original code above, you can have it jump from 1 to 3 and then to 7, then to 4 if you really want.

Thanks! But, if possible do you know an example using ansi escape codes?

Dunno what that is, so I'm gonna say no.

If you just want a menu where the user can select between 1 and 10, that'll do the job, no need for "ANSI escape sequences". If I have a moment in a couple of minutes, I'll lookup ANSI escape sequences and see if I can work it out, but I probably won't be able to, because I really can't program.

There are ANSI escape codes in that code SifJar posted.

printf("Choice: %d", nSelected);

Since you appear to know what they do, use them as you please. They will all work.
