Weird problem, some GRRLIB_DrawImg (same code) does not render

I have the same code in the int main, and some void, like "void splash()".
All inside a "while" loop. But only the screens inside the main() are drawn correctly.

Is almost the same code in both parts of source, but PNG textures (GRRLIB_Printf, GRRLIB_DrawImg) just don't render in void arrays, only "GRRLIB_Rectangle". Why?
I need some help.

BTW, I'm using devkitPro (devkitPPC) and coding for Wii, with GRRLIB 4.3.0.

Tks.

Could you give us some details for your image: width and height
What software did you use to convert your PNG to .c/.h files?

Re: Weird problem, some GRRLIB_DrawImg (same code) does not render

Background: 640x480, JPEG.
Cursor: 48x48, PNG.
Font: generated by WiiBuilder, image 960x60, tiles 20x30, PNG.

All conversions made by raw2c.


I must be doing something stupid, but I'm still confused why some screens work and other don't, with basically the same code.




Here a part of the source:

Code:

#define BUILD_DATE "WORKPRINT 23-10-2010"
#define BUILD_VER "V0.01a"

#include <stdio.h>

#include <malloc.h>
#include <math.h>
#include <ogcsys.h>
#include <gccore.h>
#include <wiiuse/wpad.h>
#include <GRRLIB.h>
#include <pngu.h>

#include "img/title.h"
#include "img/bg.h"
#include "img/button.h"
#include "img/buttoff.h"
#include "img/cursor.h"
#include "img/font2.h"

#define GRRLIB_BLACK   0x000000FF
#define GRRLIB_GRAY    0xE6E6E6FF
#define GRRLIB_WHITE   0xFFFFFFFF

void splash1()                                                                                   // Splash screen not rendering fonts or cursor.

Re: Weird problem, some GRRLIB_DrawImg (same code) does not render

I don't understand, does your code compiles? Because it looks like you declared all your textures in main() and you use them in splash1()??? The scope for all your GRRLIB_texImg * is limited to main!

Yes, it compiles.
What do you mean by "The scope is all your GRRLIB_texImg * is limited to main"?


I am newbie in this, using this as a learning task.



EDITED: I said: I'm a newbie and the problem was stupid... GRRLIB_texImg inside void splash() and others... and the problem SOLVED.
Thanks!
