Hey everyone,

 

I've been playing around with fluids and I want to add a custom recipe to enable a player to get it in survival. I noticed that that when you do craft the item (dust + water bucket), the player gets an extra empty bucket. I assume that this is because Minecraft recognizes that in vanilla recipes (Cake for Example) you don't want to take the bucket from the player.

 

This lead me to believe that I should get a handler that subscribes to ItemCraftedEvent, looks at the event to see if my custom bucket is created and if there is an empty bucket in the players inventory, and removes one bucket using "consumeInventoryItem"

 

However, after further inspection, it appears that empty bucket that is given to the user shows up after the event has been triggered and thus doesn't removed.

 

Is there a good method to handle this situation?

I have discovered a potential answer to this solution. I simply added ".setContainItem(null)" to the "Items.water_bucket" in my crafting recipe. The final code would looks like this (Note, this is just an example:

 

GameRegistry.addShapelessRecipe(
    new ItemStack( myItem ),
    new Object[] {
         Items.ender_pearl,
         Items.water_bucket.setContainerItem(null)}
);

To provide some further information, here's the event handler class that I have.

 

package net.roymond.testingMod.EventHandler;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Items;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.roymond.testingMod.mainClass;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent.ItemCraftedEvent;

public class CraftingHandler {

public static CraftingHandler INSTANCE = new CraftingHandler();

private CraftingHandler(){
}

@SubscribeEvent
public void PlayerEvent(ItemCraftedEvent event){
	ItemStack craftedItem = event.crafting;

	if (event.crafting.getItem() == mainClass.roymondBucket){
		System.out.println("Desired item has been crafted.");
		for (int i=0; i< event.player.inventory.mainInventory.length; i++){
			System.out.println(event.player.inventory.mainInventory[i]);
			//Prints each slot out on a line.
		}

		if (event.player.inventory.hasItem(Items.bucket)){
			System.out.println("Player has Item. Cleared to remove it");
		}
	}
}


}

 

So this will report to me that the desire item has been crafted and will report back the player's inventory but if you go through the player's inventory you will not see a bucket (Items.bucket).

 

Any ideas on how I can capture this bucket so I can get rid of it?

         Items.water_bucket.setContainerItem(null)}
);

 

Hopefully this helps someone in the future.

Yes, it helped.

 

Thanks man! Good Job

Yeah, you are right.

Is there nothing like "if you craft the with a water bucket and you have crafted a malt bucket, then return this.setContainerItem(null) else return this.setContainerItem(items.bucket)"?

I appreciate your help, I will try to figure out a way. Hopefully there is!

guys found a pretty easy way

Item lavaNoContainer = Items.lava_bucket;
lavaNoContainer.setContainerItem(null);

Item waterNoContainer = Items.water_bucket;
waterNoContainer.setContainerItem(null);

 

Then use these to items to craft your stuff. This worked for me and shouldn't break other mods. The weird thing is that it worked without registering which is really great

[me=Draco18s]skips the local variable assignment.[/me]

 

Items.lava_bucket.setContainerItem(null);

Yeah ur right tried it. is there any other way to do this in 1.7.10?

Suggestion: Change ur whole approach to brew a potion instead (3 bottles of water plus dust ingredient yields 3 bottles of new mystery fluid). Then you just need a way to convert your potion into a fluid source block when you use it in the world.
