[1.7.10] Adding trade to "new" villager type mob

[DonKresenko]

First of all, I'M NOT MAKING A NEW VILLAGER TYPE (that one is easy), I'm making a new MOB that can trade with the player and has only 1 trade. The mob has a custom model and custom render (that part is done), but I can't get the trade to work. The GUI shows up when i right-click on a mob, but there's a blank trade (see photo). Anyone know how to fix it? Would help

Entity code

package com.blabla.test;

import net.minecraft.entity.passive.EntityVillager;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Items;
import net.minecraft.item.ItemStack;
import net.minecraft.util.Tuple;
import net.minecraft.village.MerchantRecipe;
import net.minecraft.village.MerchantRecipeList;
import net.minecraft.world.World;

public class EntityWizard extends EntityVillager {

private MerchantRecipeList buyingList;

public EntityWizard(World w) {
	super(w);
}

@Override
public MerchantRecipeList getRecipes(EntityPlayer player) {
	if (this.buyingList == null)
        {
            this.addDefaultEquipmentAndRecipies(1);
        }

        return this.buyingList;
    }

@Override
public void setRecipes(MerchantRecipeList recipeList) {
	recipeList.add(new MerchantRecipe(new ItemStack(Items.ghast_tear, 8, 0), null, new ItemStack(Items.arrow, 16)));
}

public void addDefaultEquipmentAndRecipies(int i) {
	MerchantRecipeList merchantrecipelist;
        merchantrecipelist = new MerchantRecipeList();
        
        merchantrecipelist.add(new MerchantRecipe(new ItemStack(Items.ghast_tear, 8, 0), null, new ItemStack(Items.arrow, 16)));
        
}

}

[coolAlias]

You made a 'new MerchantRecipeList' but only assign it to a local variable within the method - you never assign anything to your 'buyingList', thus it is always empty (null).

[DonKresenko]

I have a check where if it's null then will return a recipe. But isn't working. Know how to fix it?

[DonKresenko]

Got the recipe working, but it crashes when i use the trade

Not sure why the crash, but I am noticing that

addDefaultEquipmentAndRecipies

does nothing.

[coolAlias]

Your problem is that you are extending EntityVillager, but buyingList and addDefaultEquipment are both PRIVATE members of EntityVillager - you cannot use or override them without Reflection or ASM.

 

What you can do, however, is override getRecipes to return your own list, but because you override EntityVillager, your mob is still using the villager's buyingList (which is NULL) when useRecipe or any other villager method is called.

 

You either have to override every method from EntityVillager which interacts with buyingList and make it use your own list, or you need to not extend EntityVillager and just implement IMerchant instead.

Ok, thank you guys
