Reading array causes crash ,stupid error?

[perli55]

When I read from the array called "world" , my wii crashes and
dolphin emulator gives the error "tring to compile at 0,LR=00000000", this is my code:

Code: Select all

#include <stdlib.h>
#include <grrlib.h>
#include <math.h>
#include <ML.h>

#define BLACK  0xFFFFFFFF
#define RED    0xFF0000FF
#define GREEN  0x00FF00FF
#define BLUE   0x0000FFFF
#define YELLOW 0xFFFF00FF

#define random(min,max) ((min)+rand()%((max)+1))
#include <verdana_ttf.h>

f32 x=0;
f32 y=0;
f32 z=3;
f32 a1=0;
f32 a2=0;

int main()
{

	ML_Init();
	
	GRRLIB_ttfFont* font = GRRLIB_LoadTTF(verdana_ttf,verdana_ttf_size);

	u8 ty=0;
	u8 tz=0;
	for (tx=0;tx<64;tx++) {
		for (ty=0;ty<64;ty++) {
			world[tx][ty][0]=1;
		}
	}
	
	while (!ML_Pressed(cHome))
	{
		ML_Update(0);
		camera();
		
		GRRLIB_3dMode(0.1,1000,90,0,1);
		GRRLIB_Camera3dSettings(x,y,z,0,0,1,x+cos(a1),y+sin(a1),z+sin(a2));
		GRRLIB_SetLightDiff(0,(guVector){x,y,z},3,1,0xFFFFFFFF);

				}
			}
		}
		
		GRRLIB_2dMode();
		sprintf(str,"%.2f %.2f %.2f %d",x,y,z,5); // <---------------- replacing 5 with world[0][0][0] results in crash
		GRRLIB_PrintfTTF(10,40,font,str,16,YELLOW);
		
		GRRLIB_Render();
	}
	
	return 0;
}

Your world array is larger than the stack allocated to the main thread, either declare it globally (outside your main function) or allocate it dynamically using new or malloc. I have no idea what <grrlib.h> or <ML.h> are either but you should probably be aware that we provide no support for libraries not supplied by devkitPro.

Thank you!
