Hi everyone ,

it's finally the release day!

this is my first homebrew so please be indulgent .

it's still need some minor adjustement but work complety fine .

i use a tricky way to generate a random number.(i will explain later).

i will give my code for the next update with lots of comment , that way beginner can easely understand it and i hope make there own to grow the community.

i post the 550 and 532 in the zip , but i don't have a 532 system to verify if this work.

Comments and Critics are welcome.

Ryuutseku85



The game will be simple :
find the mysterious number , the wiiu will search for a mysterious number , it will ask you what is it , and it will answer , "more" , "less" or "congratulations !!! you win ".
all of you now this game , right ?
so lets begin ,

i have this code
loader.c
Code: 
#include <stdio.h>
#include <stdlib.h>

#define BUTTON_ZR       0x0040
#define BUTTON_L        0x0020

#define BUTTON_STICK_L  0x00040000
#define BUTTON_TV       0x00010000

and loader.h
Code: 
#include "../../../../../../../devkitPro/libwiiu/src/coreinit.h"
#include "../../../../../../../devkitPro/libwiiu/src/vpad.h"
#include "../../../../../../../devkitPro/libwiiu/src/draw.h"
#include "../../../../../../../devkitPro/libwiiu/src/string.h"

void _getIN();

the problem is that actually nothing work , i don't know how to wrote something on the screen , and do how to make the player answer . i find i will do an void exit for the end too .

thanks for your help.

For writing you can use __os_snprintf(). Check osscreenexamples/ios for an example. For the answering you can do the following:
0. you need one variable for the number and one for the current position.
1. check for input (up, down, left, right, a)
2a. if left, current position + 1, if right, current position -1.
2b. if up, number = (number-(number/10^position)*(10^position)) + (((number/10^position)%10+1)%10)*10^position, assuming you start at position 0. This basicly just increases the number on a specific position to 1 and in case you leave the current position, it will be resettet to 0.
2c. analog to above, just subtract for down.
2d. for a apply it
3. draw the current number with some arrows. You can do this with simple math for positions

use this just as an idea on how to do it, there is still lots of stuff to do for it to work completly.

hi ,
can someone explain me how this fu*****g __os_printf work , please?

i made my structure for the button and title
Code: 
struct rendertext
{
  int a;
  int b;
  int x;
  int y;
  char output[1000];
};

struct title
{
  int mysteriu;
  int press_a;
  char title[1000];
};

then made my initialisation
Code: 
struct rendertext text;
    text.a=0;
    text.b=0;
    text.x=0;
    text.y=0;

    struct title titre;
    titre.mysteriu=0;
    titre.press_a=0;
    while(1)

the i start the game
Code: 
just before that we have ou initialisation of both struct

while(1)
    {
        VPADRead(0, &vpad_data, 1, &error);




//game start//

int choice = 0;


do
{choice = 0;

        int Number = 0 ;

        int compteur = 0;

        int nombreentre = 0;

        int nombremystere = 8;

        const int min = 1 ;

        const int max = 10;

        int ask = 0;
     
    do
    {

        __os_snprintf(titre.title,1000,"MysteriU\n");
        __os_snprintf(titre.title,1000,"Press A to play.\n");
        if (vpad_data.btn_trigger && BUTTON_A);
        {
            text.a=1;
        }
    }
    while (text.a!=1);
and i got a blank screen i also try with the drawstring and _printstr
(the only one who actually print something on the screen is _printstr , but i can do anything after that , i think the wiiu just freeze.)

thanks for those who gonna help me.

Let me help you out.
First you should have a look at this:
www.learn-c.org

It should help you to understand the basics of C.

__os_snprintf doesnt print anything on the screen. It just format the char buffer like this:
Code: 
char buffer[255];
__os_snprintf(buffer,  255, "Simple String.");

The string "Simple String" was put into the buffer variable.
Now you can take the buffer and put it as a parameter in your _printstr function:

Code: 
char buffer[255];
__os_snprintf(buffer,  255, "Simple String.");

_printstr(buffer);

If you want to put an integer in a string you can use a placeholder and add an agrument:

Code: 
int integer = 53421;
char buffer[255];
__os_snprintf(buffer,  255, "The integer has the value: %i", integer);

_printstr(buffer);
__os_snprintf is documented here: http://wiiubrew.org/wiki/Coreinit.rpl#Internal

__os_snprintf is a wiiu equivalent to the function snprintf at other operating systems and its handling is the same.
Look at this page http://www.cplusplus.com/reference/cstdio/snprintf/ for more formating options.



I hope it would help you a littlebit.

hi ,

so here we go again ...

first off :
in the browser we have a rpl call randgen.rpl and it get NSSGetRandom function that need two arg (obviously min and max in my case).

so this being said , let's go to the problem (again an other ?)
so i have my code , nothing seem wrong to me , but i don't know why but my wiiu freeze at my screen start .

here is my c code :
Code: 
#include "loader.h"
#include "control.h"

void _start ()
{


    asm(
        "lis %r1, 0x1ab5 ;"
        "ori %r1, %r1, 0xd138 ;"
        );

    uint32_t coreinit_handle;
    OSDynLoad_Acquire("coreinit.rpl", &coreinit_handle);

    OSDynLoad_FindExport(randgen_handle, 0, "NSSGetRandom", &NSSGetRandom);// get nssgetrandom from wiiu browser//

    return NSSGetRandom(min,max);
}

so ? , what i don't do correctly ? maybe @brienj can help me with it cause i take exemple on his liteNESU menu.

The randgen.rpl isnt a real lib provided by the os. I think this cause the freeze.

And the default implemented rand function, provided by cstdlib, will freeze the wiiu if you executing it from the userspace. I dunno if it works correctly with kexploit and a clean startup environment.

@Kakkoii has post a nice libary to get random numbers.
https://gbatemp.net/threads/wiiu-homebrew-development.391050/page-11#post-6160401

Alternative you can write a pseudo random function.

You can just call _Exit() as-is, because it's address is hardcoded into the coreinit.h file in libwiiu/src, so you don't have to void it to declare it.

Same with OSFatal(). Also, why print()? You could try some of the OSScreen functions, or just use OSFatal()

not bad for a first program though :}

A bit of self promotion, but I have a lot of examples you might want to see in Space Game.

For pseudo-random numbers, I use this function, which you can invoke by passing the pointer to an integer (a seed) like this. To initialize the seed, you can base it off the time.

Another great resource is Eliboa's Snake. Cool stuff so far :)

Thanks Mr rean , but come tell me it again when I will release it lol .
Vgmoose , each time I ask me something I take a look at two homebrew that ( I think ) are the most teachfull , they are lite NESU and ... Space game lol .

For snake , I find it hard to understand with the use a structure and the name that don't evoke something like for example the s* for snack .

Yours explain me how the vpad_data function work and how to use it .

For the random generator I think I may have find a different way that I will explore .

Thanks a lot for your support , until brienj or anyone else explain me the menu I will do it the old way lol .

When I will finish this , I think I gonna make a big tuto for the noob's one , so I can help them the wway some of you help me :)

The menu I used, uses arrows for the selection part. By changing the menuLine value, it makes the arrows get drawn on a different line. You need to make sure that you are including a header that defines the DrawString function you are using. Without seeing all of your source code, it is hard to determine exactly where any problem may lie.

Like I told you on the other forums, you could use the TinyMT library, it is what I started using in AstUroids not long after starting that project. It works perfectly on the Wii U, or if you want one simple function, use the random number generator that vgmoose uses in his Space Game.
