Getting Started

Hi. I'm working on my first plugin and I was wondering, how would you add a new furnace recipe? It's a simple plugin that turns coal into diamond. Here is my code.

Code:

package me.Zachster.CoalToDiamond;

import java.util.logging.Logger;
import org.bukkit.Material;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class CoalToDiamond extends JavaPlugin {
    Logger log = Logger.getLogger("Minecraft");
    public void onEnable() {
        log.info("Coal To Diamond v1.0 is now enabled!");
    }
    public void onDisable() {
        log.info("Coal To Diamond v1.0 is now disabled!");
    }
    public void FurnaceRecipe(ItemStack result, Material source) {
    result = new ItemStack(Material.DIAMOND, 1);
    source = Material.COAL;
    }
}

 

This should help

Code:

public void addRecipesToServer(CoalToDiamond plugin)
    {

            int sourceId = 263; //coal
            int resultId = 264; //diamond
            int resultQuantity = 1;

            ItemStack item = new ItemStack(resultId, resultQuantity);
            FurnaceRecipe recipe = new FurnaceRecipe(item, new MaterialData(sourceId));

            plugin.getServer().addRecipe(recipe);
    }

 

Code:

package me.Zachster.CoalToDiamond;

import java.util.logging.Logger;
import org.bukkit.inventory.FurnaceRecipe;
import org.bukkit.inventory.ItemStack;
import org.bukkit.material.MaterialData;
import org.bukkit.plugin.java.JavaPlugin;

public class CoalToDiamond extends JavaPlugin {
    Logger log = Logger.getLogger("Minecraft");
    public void onEnable() {
        log.info("Coal To Diamond v1.0 is now enabled!");
    }
    public void onDisable() {
        log.info("Coal To Diamond v1.0 is now disabled!");
    }
    public void addRecipesToServer(CoalToDiamond plugin)
    {

            int sourceId = 263; //coal
            int resultId = 264; //diamond
            int resultQuantity = 1;

            ItemStack item = new ItemStack(resultId, resultQuantity);
            FurnaceRecipe recipe = new FurnaceRecipe(item, new MaterialData(sourceId));

            plugin.getServer().addRecipe(recipe);
    }
}

It didn't work. Did I put the code in the right place?

 

It's a method so you have to call it. Ideally, it should be called when your plugin is loaded.

 

Ok. I know it says null but that's what Eclipse suggested. Sorry for all the questions. I'm half asleep right now.

Code:

package me.Zachster.CoalToDiamond;

import java.util.logging.Logger;
import org.bukkit.inventory.FurnaceRecipe;
import org.bukkit.inventory.ItemStack;
import org.bukkit.material.MaterialData;
import org.bukkit.plugin.java.JavaPlugin;

public class CoalToDiamond extends JavaPlugin {
    public void addRecipesToServer(CoalToDiamond plugin)
    {

            int sourceId = 263; //coal
            int resultId = 264; //diamond
            int resultQuantity = 1;

            ItemStack item = new ItemStack(resultId, resultQuantity);
            FurnaceRecipe recipe = new FurnaceRecipe(item, new MaterialData(sourceId));

            plugin.getServer().addRecipe(recipe);
    }
    Logger log = Logger.getLogger("Minecraft");
    public void onEnable() {
        addRecipesToServer(null);
        log.info("Coal To Diamond v1.0 is now enabled!");
    }
    public void onDisable() {
        log.info("Coal To Diamond v1.0 is now disabled!");
    }
}

 

Yeah, that was my mistake. When I gave you the example, I was in the mindset of putting it in its own or another class, but in your case the argument to the addRecipesToServer method is unnecessary . Anyways you have two options: move the method to another class, or edit the method so that it takes no arguments and so that its last line is just getServer().addRecipe(recipe);

 

It worked. Thank you so very much.
