[1.7.10] [Not Solved] Change Item Metadata on Keypress

[Whyneb360]

My problem is as the title says. I am trying to change an items metadata on a key-press. My current code is as follows (apologies in advance, but I can't seem to get the insert code function to work):

 

public class GliderKeybinding {

public static final int TOGGLEGLIDER = 0;

private static final String[] desc = {"Open/Close Glider"};

private static final int[] keyValues = {Keyboard.KEY_R};

private final KeyBinding[] keys;

public boolean GliderActive;

public GliderKeybinding() {

keys = new KeyBinding[desc.length];

for (int i = 0; i < desc.length; ++i) {

keys = new KeyBinding(desc, keyValues, "Elemental Imperium");

ClientRegistry.registerKeyBinding(keys);

 

 

}

}

 

 

 

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

if (keys[TOGGLEGLIDER].isPressed() && Minecraft.getMinecraft().thePlayer.inventory.getItemStack() == par1itemstack) {

if (GliderActive) {

GliderActive = false;

setDamage(par1itemstack, 1);

}else{

GliderActive = true;

setDamage(par1itemstack, 0);

}

}

}

 

 

private void setDamage(ItemStack par1itemstack, int i) {

 

}

}

 

===== And I have registered it as:======

 

FMLCommonHandler.instance().bus().register(new GliderKeybinding());

 

 

What have I done wrong?

 

Many thanks in advance,

Well, first of all in the method where you are trying to change the meta data of the item you forgot to add the part that tells which item is supposed to be in the player inv. thus the same goes for the item that you are trying to change the meta data from.

[Whyneb360]

Thanks, but how would I go about doing this?

[nexusrightsi]

by changing the par1itemstack's with your glider item.

[Whyneb360]

When I try to do that, it gives an error in eclipse:

 

x Incompatible operand types ItemStack and Glider

 

Any suggestions?

[nexusrightsi]

well yeah, don't reference to the actual class but reference to the registered item in probably your main class.

 

you know, the "public static Item Glider = new Glider() bla bla bla"

[Whyneb360]

Now I have done this:

 

@SubscribeEvent

public void onKeyInput(KeyInputEvent event) {

if (keys[TOGGLEGLIDER].isPressed()) {

if (GliderActive) {

GliderActive = false;

setDamage(ElementalImperium.Test, 0);

System.out.println("Glider Deployed");

}else{

GliderActive = true;

setDamage(ElementalImperium.Test, 1);

System.out.println("Glider Restracted");

}

}

}

 

 

public void setDamage(Item test, int i) {

 

}

}

 

 

and that works for the println, but not the setDamage. Did I reference the item wrong?

 

Thanks for bearing with me

So, my code is as follows:

 

public class Glider extends Item
{
private String[] name = {"staff", "glider"};

@SideOnly(Side.CLIENT)
private IIcon[] icons;

public static final int TOGGLEGLIDER = 0;
private static final String[] desc = {"Open/Close Glider"};
private static final int[] keyValues = {Keyboard.KEY_R};
private final KeyBinding[] keys;
public static boolean GliderActive;
private ItemStack Glider;

public Glider() {

	keys = new KeyBinding[desc.length];
	for (int i = 0; i < desc.length; ++i) {
		keys[i] = new KeyBinding(desc[i], keyValues[i], "Elemental Imperium");
		ClientRegistry.registerKeyBinding(keys[i]);

		setUnlocalizedName(Constants.MODID + "_" + "test");
		setHasSubtypes(true);
		setCreativeTab(ElementalCreativeTab.elementalimperium);
		setMaxStackSize(1);
		setFull3D();

	}
}


@Override
public String getUnlocalizedName(ItemStack par1ItemStack) {
	int metadata = MathHelper.clamp_int(par1ItemStack.getItemDamage(), 0, 15);

	return super.getUnlocalizedName() + "." + name[metadata];
}

@SideOnly(Side.CLIENT)
@Override
public void registerIcons(IIconRegister par1IconRegister) {
	icons = new IIcon[name.length];

	for (int i = 0; i < icons.length; i++) {
		icons [i] = par1IconRegister.registerIcon(Constants.MODID + ":" + "test" + " " + name[i]);
	}
}

@Override
public IIcon getIconFromDamage(int par1) {
	return icons[par1];
}


@SuppressWarnings ({"unchecked", "rawtypes" })
@SideOnly(Side.CLIENT)
@Override
public void getSubItems(Item par1, CreativeTabs par2CreativeTabs, List par3List) {
	for (int x = 0; x < name.length; x++)
	{
		par3List.add(new ItemStack(this, 1, x));
	}
}

@SubscribeEvent
public void onKeyInput(KeyInputEvent event) {
	if (keys[TOGGLEGLIDER].isPressed()) {
		if (GliderActive) {
			GliderActive = false;
			System.out.println("Glider Deployed");
		}else{
			GliderActive = true;
			System.out.println("Glider Restracted");
		}	
	}
}
}

 

Okay, so what I am trying to do in the last bit is change the metadata on the key-press of 'R'. I've been told I need to use a packet, and was wondering if anyone could link me to, or supply something that would help me.

 

Any help would be useful

Thanks in advance
