Libwiisprite Sprite error

Just started to use libwiisprite, and I can't seem to get passed the sprite error. I am using the libwiisprite tutorial on wiibrew.

#include 
#include 
 
// libwiisprite uses wsp as it's namespace
using namespace wsp;
 
int main(int argc, char **argv)
{
	// Create the game window and initalise the VIDEO subsystem
	GameWindow gwd;
	gwd.InitVideo();
 
	gwd.SetBackground((GXColor){ 255, 255, 255, 255 });
 
	// Initialise Wiimote
	WPAD_Init();
 
	for(;;)
	{
		WPAD_ScanPads();
		if(WPAD_ButtonsDown(WPAD_CHAN_0)&WPAD_BUTTON_HOME)
			break;
		gwd.Flush();
	}
	return 0;
}

That code compiles perfectly, but as soon as I add:

Sprite sprite;

Adding that both above and below the int main part causes this error:

Any ideas?

Those missing functions are no longer found in libogc.a, but in gx.h. You need to either recompile your libwiisprite.a, or find one built with the current libogc.

okay, thanks a ton

There is a a library that works with the current libogc here: Arikado's Page

Ahh thank you. Now the question is, how do I make animation sequences from a sprite sheet? I didn't understand the tutorial that much.
I understand the sprite sheet and how to divide it up into different tiles, but how do I use each tile in a sequence?

To make a sprite sheet, first figure out what you would like the size of each frame to be. Remember that you must choose a width and height value that is a multiple of 4.

After that, make a .png image with images (frames/tiles) of that specified width and height value. Save the entire thing as one .png image.

Then in your code:

//Initialize for rendering
Image MySpriteSheet;
Sprite MySprite;
MySpriteSheet.LoadImage(path);
MySprite.SetImage(MySpriteSheet, width, height);

//Render
MySprite.SetPosition(X, Y);
MySprite.Draw();

//Advance to the next frame
MySprite.Next();

//Advance to the previous frame
MySprite.Prev();

Thank you very much!
