Hello, I created a custom chestplate and i'd like to make the chestplate provide a special effect when a certain button is pressed, I'm not sure how could i do this..

 

KeyBindings Class:

package phonixe.phoenixcraft.network;

import org.lwjgl.input.Keyboard;

import net.minecraft.client.settings.KeyBinding;
import net.minecraftforge.fml.client.registry.ClientRegistry;

public class PhoenixCraftKeyBindings {
    public static KeyBinding flyWings;
    public static void init() {
    flyWings = new KeyBinding("key.flyWings", Keyboard.KEY_R, "key.categories.phoenixcraft");
    ClientRegistry.registerKeyBinding(flyWings);
    }
}

 

InputHandler:

package phonixe.phoenixcraft.network;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemArmor;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.InputEvent;
import phonixe.phoenixcraft.items.RedFirePhoenix_Chestplate;

public class PhoenixCraftKeyInputHandler {
@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event) {
	if(PhoenixCraftKeyBindings.flyWings.isPressed()) {
	}
}
}

There are two things that much be true for your keybind to do anything.

 

1) The key needs to be pressed

2) The player needs to be wearing the armor

3) the server needs to know about it

 

You've got #1 at the moment, now do #2 and #3.

You could also try a method more like this. It works with items, but I don't know about armor.

 

 

@Override

public void onUpdate (ItemStack stack, World world, Entity entity, int par4, boolean par5){

super.onUpdate(stack, world, entity, par4, par5);

{

 

EntityPlayer player = (EntityPlayer) entity;

ItemStack equipped = player.getCurrentEquippedItem();

 

 

 

if (Keyboard.isKeyDown(Keyboard.KEY_F)) {

 

player.supercoolthingyouwantyourarmortodo;

   

 

}

}

 

 

This will not work on the dedicated server.  The server doesn't necessarily know what a "keyboard" is, much less which player is pressing it.

Well here's my current InputHandler, I'm pretty sure i'm messing this up royally as i'm not sure how to do this. Also how could i let the server know of this?

 

package phonixe.phoenixcraft.network;

import javax.annotation.Nullable;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Items;
import net.minecraft.inventory.EntityEquipmentSlot;
import net.minecraft.item.ItemArmor;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.InputEvent;
import phonixe.phoenixcraft.init.PhoenixCraftItems;
import phonixe.phoenixcraft.items.RedFirePhoenix_Chestplate;

public class PhoenixCraftKeyInputHandler {
private ItemStack ItemStack;
@SubscribeEvent
public void onKeyInput(InputEvent.KeyInputEvent event) {
	ItemStack itemstack = this.getItemStackFromSlot(EntityEquipmentSlot.CHEST);
	if(PhoenixCraftKeyBindings.flyWings.isPressed()) {
		if (itemstack.getItem() == PhoenixCraftItems.redfirephoenix_chestplate){

		}
	}
}

public ItemStack getItemStackFromSlot(EntityEquipmentSlot slotIn) {
	return ItemStack;
}

public void setItemStackToSlot(EntityEquipmentSlot slotIn, @Nullable ItemStack stack) {
}
}

private ItemStack ItemStack;

The fuck?

	public ItemStack getItemStackFromSlot(EntityEquipmentSlot slotIn) {
	return ItemStack;
}

Double da-fuck?

 

Also how could i let the server know of this?

 

The magic of packets.

Alright i got the effect to activate when the button is pressed, but i'm still unsure how i could make sure that the player is wearing the chestplate ._.

When the key is pressed: tell the server

The server then checks if the player is wearing the armor.

And if so, activates the effect.

It works perfectly, thank you!
