[1.6.4] Keybinding opening gui PLEASE HELP

[chiyin00]

I would like to use keybinding to open my gui. I could see my KeyBinding in the setting but when I press P it does not pop the GUI out. This is what I've done:

 

Main Class:

@EventHandler
        public void postInit(FMLPostInitializationEvent event) { 
        	KeyBindingRegistry.registerKeyBinding(new KeyBindingHandler());
        	

 

KeyBindingHandler class:

public class KeyBindingHandler extends KeyHandler {

public KeyBindingHandler() {
	super(arrayOfKeys, areRepeating);
}

public static KeyBinding test = new KeyBinding("SAO", Keyboard.KEY_P);
public static KeyBinding[] arrayOfKeys = new KeyBinding[] {test};
public static boolean[] areRepeating = new boolean[] {false};
public Minecraft mc;

@Override
public String getLabel() {
	return "Test KeyBinding";
}

@Override
public void keyDown(EnumSet<TickType> types, KeyBinding kb,
		boolean tickEnd, boolean isRepeat) {
	mc.displayGuiScreen(new YourGui());

}

@Override
public void keyUp(EnumSet<TickType> types, KeyBinding kb, boolean tickEnd) {

}

@Override
public EnumSet<TickType> ticks() {
	return null;
}

}

 

My Test GUI class:

public class YourGui extends GuiScreen{

    private GuiScreen parentScreen;

    public void initGui()
    {
            
    }

    public void drawScreen(int par1, int par2, float par3)
    {
            drawDefaultBackground();
            
            super.drawScreen(par1,par2,par3);
            
    }
}

 

Please help guys
