I was already using it. Despite that, it says that input is undeclared.

st4rk Here's my code: https://github.com/AlbertoSONIC/3DSBinaryConverter

you have input defined inside a while loop so it'll be limited to that scope.
define it once at the top of you main function then set the value throughout your program

I completely forgot that! Thank you! So inside while, i just leave input=hidKeysDown(), without u32, right?

Github repository updated. Thank you!

Now it's time to fix that drawstring issue!

Now it's time to fix that drawstring issue!

The issue was that it is mirrored on y axis. That was my fault. I wrote the function.

Please update the drawPixel function:

Code:

void drawPixel(int x, int y, char r, char g, char b, u8* screen)
{
    int height=TOP_HEIGHT;
 
    if(*screen & TOP_SCREEN)
    {
        height=TOP_HEIGHT;
    }
    else
    {
        height=BOTTOM_HEIGHT;
    }
    u32 v=(-y+x*height)*3;
    screen[v]=b;
    screen[v+1]=g;
    screen[v+2]=r;
}

I'll give it a try tomorrow! Goodnight guys!

actually it should be change to
u32 v = (height-1-y+x*height)*3;
otherwise v will hold the wrong index which could occasionally be negative

Thanks I changed it.

I also noticed I wasn't determining height and width correctly for top and bottom screens. Please update to these new libs.

EDIT: Whoops. Just realized height was same on both screens:

Still get undefined draw_string error.... Please check my code: what do i need to use? Buffer or simply draw_string?

It's DrawString, not draw_string.

Also, you will need this: hidScanInput(); before you do u32input=hidKeysDown(); else you won't get any input.

Do i still need to use buffer in order to print a string? Or do i need to use it only for int variables printing?

EDIT: I tried to replace draw_string with drawString, but it says that i used too few arguments. Plus, it seems that there's something wrong with other functions too. Log here:

You seem to lack basic programming skills...

The error message is clear enough: You passed 7 arguments, but the drawString function takes 8. This is the function signature:

void drawString(char* word, int x,int y, char r, char g, char b, u8* screen,gfxScreen_t screenPos)

You didn't pass u8* screen.

Man, i've taken these draw strings codes from another launcher.dat based homebrew, which is using a completely different way to print strings. That's why i wrote that code. Also, you're probably right. I probably lack basic programming skills. Here's why: i'm 16 years old only and at my school i'm learning some useless C#. My teachers haven't teached me anything about C programming, yet. Everything i know about C is self learned. So please give me time to improve my skills, i'm working very hard on that.

So, back to topic, do i need to use buffer to write EVERY STRING or for INT variables writing only?

Here's a port of ARM9 3DSPong by Snailface.

There's a few framebuffer issues I haven't ironed out yet, but it should give you a pretty good idea of how to do a simple example with the latest ctrulib.

Sorry if this offended you. The issue though is not about C or C# (I'm myself a C#/.NET developer and have barely any knowledge about C). You should read the error messages carefully and try to understand the error instead of asking in this forum whenever you encounter the slightest problem.

On this page alone you had three problems that were language-agnostic (and are therefor part of basic programming knowledge):

You tried to use a variable outside it's scope. That'll be an error in C# aswell as in C and any other programming language.
You tried to call a method with a spelling that was wrong. The error message was very clear (undefined function). You have to call a function with the name it was defined; in C as in many other languages you even have use the correct casing. drawString and DrawString in C would be different identifier.
You passed a wrong argument list to a function. And again you got a helpful error message: too few arguments; that again would've been a problem in any other programming language.

I don't try to offend you but to help you. If you'd try to solve a problem by yourself before you ask in this thread you would learn a lot quicker and better. So, instead of calling C# useless (which it definetly isn't) you can try to apply common programming knowledge of your teachers lessons from C# to C. (if your teacher himself understands programming)

First of all, thank you for your help.
1) It was a mistake that i casually did. I've never done that error another time in the past...

2)I know that it's different. I've done this error due to what Relys said. He said me that i needed to use "DrawString" instead of draw_string. I simply replaced draw_string to DrawString in my code, then i tried to compile it and i saw that it wasn't right. I took a look at draw.c file and saw that i had to insert drawString instead of DrawString. And so i did.

3) I've seen that i needed to add another argument, but i didn't know which one, at least since your post. Again, since at school i've only used Console.WriteLine to print something, these printing methods are just over my knowledge! But i'm trying to learn them, like i did for NDS.

Also, i said that C# is useless because i can use it on windows only (at least that's what i was told), which isn't my main target. I would prefer to learn C, C++, Python and Assembly, but it seems that i have to learn them on my own.

To Relys, i'll take a look to your homebrew. I think it will be very usefull.

P.S. All i've done with C# yet is just a Console Application. Nothing complex.

This is where it usually starts. Keep up experimenting and learning.

Btw: C# isn't limited to Windows; with Mono you can use it on Mac OS X and Linux.

Thank you!

I'd like to do some arm kernel development and homebrew development and i can't use C# for that...

Python eh?

Free version of the e-book if you prefer:

http://learnpythonthehardway.org/book/

Enjoy, it's also a recommended book by the r/programming subreddit, so I'm assuming it's pretty good.
I haven't read it myself, but I plan to read it to use as material to help teach my younger cousin programming in the future.

Anyway, enjoy, and also, that same guy has a book on C as well, might want to check it out.
