[1.10.2] Potion effect on complete set of armor is worn

caliban · April 14, 2017

Hello guys,

After watching differents tutorials, i decide to put an effect on an armor set but i don't understood where put the method onArmorTick().
I read several old post on the forum but i didn't learn more ....
So i hope you will be able what is missing in my code.

Thanks

Here is my method:

	public void onArmorTick(World world, EntityPlayer player, ItemStack item)
	{
		
		//Testing if player is wearing an armor
		
		if(player.inventory.armorItemInSlot(0) != null &&
			player.inventory.armorItemInSlot(1) != null && 
			player.inventory.armorItemInSlot(2) != null &&
			player.inventory.armorItemInSlot(3) != null)
		{
			
			//Testing if player is wearing the right armor
			
			if(player.inventory.armorItemInSlot(0).getItem() == volcanite_chestplate &&
				player.inventory.armorItemInSlot(1).getItem() == volcanite_leggings && 
				player.inventory.armorItemInSlot(2).getItem() == volcanite_boots &&
				player.inventory.armorItemInSlot(3).getItem() == volcanite_helmet)
			{
				//Application of effect
				
				player.addPotionEffect(new PotionEffect(Potion.getPotionById(12), 40));
			}
		}
	}

The rest if that interest you is here: https://github.com/TheCaliban/CaliArmor/tree/master/src/main/java/com/mod/CaliArmor

In an event handler class.

I'm a little new in the world of modder, can you be a little more specific or give me an example according to my case.

(i tried different solution before asking you again and none worked)

Draco18s · April 14, 2017

public class MyForgeEventHandler {
    @SubscribeEvent
    public void pickupItem(EntityItemPickupEvent event) {
        System.out.println("Item picked up!");
    }
}


...


MinecraftForge.EVENT_BUS.register(new MyForgeEventHandler());

I saw this example on the guide page but i did not understand how it works. That's why i said be more specific

Thanks you for your help

onArmorTick is a method of Item, so you need to override it from a class that extends Item (or a subclass of it). It's only called on the Items that the player has equipped, so override it in your armour's Item class.

It's not an event, I think Draco is confused.

Sorry, I haven't been all here.

You can do this with an event, too.

The tag @Override cannot be applicate to my method, eclipse tell me to remove it.

I don't want to abuse your help but if you can check my code, you could be able to help me better

Your ModArmors class doesn't extend Item, so there's no onArmorTick method to override. You need to override it from the Item class used for your armour, not the class that registers the Items.

caliban · April 14, 2017

I did like you said, i extended my class ModArmors from Item, i have no error now but in game nothing happend when i'm wearing the armour.

Maybe i did some mistakes in my method to give the effect, can you check it and tell me if something seems strange to you

(i changed the id of slot by the new references and this the same)

Thank you

Draco18s · April 14, 2017

You need to create a new class for your armors, rather than using new Chestplate

caliban · April 14, 2017

I already created a class for my Chestplate.

For each part of the armour, there is a class named by the specific part.
So i have 4 class (Boots, Chestplate, Helmet and Leggings) that i have created

caliban · April 14, 2017

That's what i done,

I'm a little bit confused because when i'm testing my mod, this method is never called ..... so i supposed the @Override is not sufficient and i have to put my method in a specific place.

I suppose he was right so i did like he said, i extended my class ModArmors from Item

The solution is to override the method in the class that already extends Item (i.e. Chestplate, Helmet, etc.), not to make your registration class extend Item.
