Can potions be used in recipes?

So I've been playing around with using potions in recipes, and I can't seem to make it work.

Is there something that prohibits using a specific potion in a recipe?

Here's the itemstack I was trying to specify:

Code:

new ItemStack(Material.POTION,1,(short) 8196)

The recipe works fine without it, but when I add it I can't seem to get it to show up.

I just want to rule out an API limitation or something similar.

 

apparently potions given by commands and creative potions have a different damage value (this is what Ive learned from another thread)

 

They Do? I didnt know

 

I just cant' seem to sort this out... Does anyone have a working recipe I could use to understand how potions can be used in recipes?

 

Still haven't figured this out... I'm starting to think it's simply not supported by the API.

 

I guess I would just add Material.POTION to the recipe and check any other properties of the potion in PrepareItemCraftEvent. There you can set the Result to AIR (invalid recipe) or set the result to anything you want.

 

Ne0nx3r0 Where do you get your potions from? Creative or /give | brewing them yourself?

 

I would make the item stack, get the itemmeta and then check what it's name or lore is in comparison to the item you want.

 

He wants to use Potions as ingredients

 

Exactly. In craftitemprepareevent check it's name or lore. Sorry i wasn't quite clear

 

It might be better to directly look at the potion effect of the Potion.

 

Well, I'd like to allow any potions to work, and any combination of creative/generated/brewed potions to work.

That said, I can't even seem to make any specific potion method to work using something like:

Code:

recipe.setIngredient("P",Material.POTION,8196);//based on "normal" value

Code:

recipe.setIngredient("P",Material.POTION,4);//based on value given from getData

Code:

recipe.setIngredient("P",Material.POTION,42);//based on some random value from a thread

Code:

recipe.setIngredient("P",Material.POTION,-108);//based on value given from getData

I was really hoping I could avoid essentially handling custom recipes myself after the default recipe system has already done it's job, but it seems there's not really another option.

 

If you want any potion make the damage value 0 I think

 

As you (travja) said this I remembered that -1 actually is the value for "data value doesn't matter".

 

The problem is, each potion exists twice in game. One value for brewed potions, and one for creative potions, differing in their bit strings, thus differing in datavalue.

If you want to make a recipe for 1 specific potion, add it for both the creative and survival potion

 

Yeah, but then the issue is that all the potions must come from the same source, or else you would need to create an exponentially grown number of recipes for each combination times the number of times a potion is used in a given recipe.

In which case, I think it unfortunately is easier to just add a blank potion recipe then add an additional custom recipe filter... :/

Is there a way to accurately identify a potion type regardless of where it came from?

 

I suggested using -1 as data/durability value when adding the ingredient...

 

Right, but I still want to catch a specific potion, so how would I for example identify a poison potion? (Assuming this excludes poison II, splash, etc.)

 

In the PrepareItemCraftEvent get the potion, cast it to "Potion" and check what potion it actually is.

 

Hrm. That could work, assuming the itemstack in the recipe will also end up returning the same value.

I'll give it a shot, thanks!

 

But don't check the items contained in event.getRecipe(). You have to get them directly from the event.getInventory().

 

Cjreek Hrm. That's a problem, because I have a lot of recipes that could change in between resets.

I guess I'll have to track them separately...

Well, it's a bit funky, but it works.... You add the potion using -1 as the damage, then do your own checks against it.

Code:

                ItemStack[] storedComponents = this.componentRecipes.get(result);
                //Admit it, people just like using the term "matrix"
                ItemStack[] isMatrix = e.getInventory().getMatrix();
 
                for(int i=0;i<storedComponents.length;i++)
                {
                    if(storedComponents[i] != null)
                    {
                        if(storedComponents[i].getType() == Material.POTION)
                        {     
                            //Because water bottles don't have levels! -.-
                            byte componentsData = storedComponents[i].getData().getData();
                            byte matrixData = isMatrix[i].getData().getData();
 
                            if(componentsData == 0 && matrixData == 0)
                            {
                                continue;
                            }
 
                            if(componentsData == 0 || matrixData == 0)
                            {
                                return new ItemStack(Material.AIR);
                            }
 
                            if(!Potion.fromItemStack(storedComponents[i]).equals(Potion.fromItemStack(isMatrix[i])))
                            {
                                return new ItemStack(Material.AIR);
                            }
                        }
                        else if(!storedComponents[i].isSimilar(isMatrix[i]))
                        {
                            return new ItemStack(Material.AIR);
                        }
                    }
                }
