Hello again. It seems like I have a bit of a theme with my questions - metadata. I have managed to change metadata on a right click, but I wasn't sure about how to do it on a key press. Current code is as follows (apologies, but the code formatting isn't working for me):

 

public ItemStack onKeyInput(ItemStack par1itemstack, World par2world, EntityPlayer par3player) {

if (par1itemstack != null && par1itemstack.getItemDamage() == 0 && KeyBindings.pressR.isPressed()) {

setDamage(par1itemstack, 1);

}else{

if (par1itemstack != null && par1itemstack.getItemDamage() == 1 && KeyBindings.pressR.isPressed()) {

setDamage(par1itemstack, 0);

}

}

return par1itemstack;

 

}

 

----=-and-=----

 

public class KeyBindings {

 

    public static KeyBinding pressR;

    public static KeyBinding pressX;

 

    public static void init() {

 

    pressR = new KeyBinding("key.pressR", Keyboard.KEY_R, "key.categories.elemental");

    pressX = new KeyBinding("key.pressX", Keyboard.KEY_X, "key.categories.elemental");

 

        ClientRegistry.registerKeyBinding(pressR);

        ClientRegistry.registerKeyBinding(pressX);

    }

 

}

 

I am sure I have missed something simple, but I am still learning and can't see what it is. The problem, in case asked, is that nothing happens - at all. Any help is much appreciated.

 

Thanks,

Keybindings are client-side, so you are modifying the ItemStack on the client side, but you need to change is server side. You need to send a packet to the server, telling the server that the button has been pressed, and let the server change the ItemStack.

How would I go about doing this?

 

Thanks,
