Bukkit Custom Recipies

Hello there, I'm back with another Bukkit question! I am making a custom crafting recipe, but I want the user to have to have a certain permission to be able to craft it. How would I go about doing that?

 

AngryCupcake274 You would use the CraftItemEvent and cancel it if they don't have permission for the recipe.

 

Skionz How would I test what type of item they are crafting if it is a custom item? I want them to have to have a permission to craft a spawner, but they need a different permission to create a different spawner.

 

AngryCupcake274 CraftItemEvent#getRecipe();

 

Skionz After getting the recipe, how do I test it with the correct recipe? Would there be a

Code:java

if ([event].getRecipe = creeperegg.shape("***", "*$*", "***") {
// Do stuff
}

Or a

Code:java

if ([event].getRecipe = (Material.[item], Material.[item]...) {
// do stuff
}

 

AngryCupcake274 Recipe#getResult() returns an ItemStack that you can check.

 

Skionz So I could do....

Code:java

ItemStack temp = [event].getRecipe().getResult();

So if there were two different items used, how would I get both of them. Also, how would I get where they are in the crafting table?

 

AngryCupcake274 The ItemStack it returns is the result of the recipe.

 

Skionz Can an ItemStack hold all 9 values? If so, how would I test all 9 of them?

 

AngryCupcake274 As I have said before. The returned ItemStack is the result of the crafting recipe not the ingredients.

Skionz So how can I compare the ItemStack with multiple items to the crafting recipe?

 

AngryCupcake274 Why would you need to do that?

 

Skionz to make sure they are crafting my item; if they were, I could test to make sure they have permission.

 

AngryCupcake274 Or you could just check if the result ItemStack is the same as the result of your recipe.

 

Skionz I feel so stupid. I didn't have time to see your post when you wrote it, but a few minutes ago, it all just clicked in my mind. I'll test it tomorrow and report back.

 

@Skionz I'm back! So, can I use

Code:

ItemStack temp = event.getRecipe().getResult();

if (temp.equals(rh.creeper)) {
    // check for permissions
}

in my CraftItemEvent event?

 

@AngryCupcake274 No. Setup a new recipe when your plugin is enabled. There is no reason to do that.

 

@Skionz I forgot to mention (sorry!), that in another class, there is a list of all the ItemStacks and ShapedRecipes to craft. The "rh.creeper" is the ItemStack for a creeper egg. Is my code above the correct way to test the two ItemStacks?

 

@AngryCupcake274 The ItemStacks must be completely similar though. What is even the point of this? I don't get why you need to compare them at all.

 

@Skionz I'm testing to see if the result of what the player is crafting is the same as the creeper egg ItemStack. If it's true, then I test to see if they have permissions to do it.

 

@AngryCupcake274 I get it now; however, I would compare materials instead.

 

@Skionz the reason I do this is because that Material would be....

Code:

Material.MONSTER_EGG, 1, (short) 50

Also, I'm now getting a new error:

@AngryCupcake274 You never use '#' in your recipe so it is redundant.

 

@Skionz Wow. I feel so stupid....again.

Now my program isn't letting me craft my items. There is no output, when I put the items in it doesn't give me the output. Is there a special listener I need? The code for my ListenerManager class is below:

Code:

package me.AngryCupcake274.SpawnerManager;

import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.CraftItemEvent;
import org.bukkit.inventory.ItemStack;

public class ListenerHandler implements Listener {

    private final RecipeHandler rh;

    int test = 1;

    public ListenerHandler(RecipeHandler rh) {
        this.rh = rh;
    }

    @EventHandler
    public void onInteract(CraftItemEvent event) {
        Player p = ((Player) event).getPlayer();

        ItemStack temp = event.getRecipe().getResult();

        if (temp.equals(rh.creeper)) {
            // player tried to craft creeper egg

            if (p.hasPermission("spawnermanager.egg.creeper")
                    || p.hasPermission("spawnermanager.egg.*")
                    || p.hasPermission("spawnermanager.*")
                    || p.hasPermission("*.*")) {
                // player has permission
               
                event.setCancelled(false);
            } else {
                // player does not have permission
               
                event.setCancelled(true);
                p.sendMessage(ChatColor.RED + "You don't have permission!");
            }
        }
    }
}

 

@AngryCupcake274 Your casting a CraftItemEvent instance to a Player then using getPlayer()? An exception is most likely being thrown. I suggest you fix that.

 

@Skionz the problem is that my item isn't being crafted, when I put the items in the crafting table, there is no output item. Also, I changed my getPlayer() to getWhoClicked(). I hope that fixes the player issue.
