[Unresolved] Multi-input output furnace

[mrminecraftiful]

I am coding a multi-input output furnace(3 input, 3 output), I know how to add slots but I'm unsure how to add recipes to them correctly,

here is my code that I have:

 

tile entity:

This is really taking me for loop can anyone help?

[Moritz]

Just make the 3 input slotids and 3output next to each other.

and make a for loop. That should help.

that was kinda vague, how would I use them in a for loop and does it go into the recipes or tileentity?

I have a nice 'n' efficient recipe system, which you are free to use if you like. Link to github is in my sig.

After reading threw your code, I found that what you do would require the recoding of all my classes, and also from what I saw it looks like this code uses almost like a shapeless crafting recipe.  What i need is if the input is a certain three items you get a certain three items. Do you know another way to do this?

Sure. You will probably want some sort of recipe class, or at least a deep hashmap.

it would be great if you could put me on the right path

Look, I'm not here to write your code for you. I'm here to tell you what you're doing wrong. If you don't understand how to code, there are books and tutorials available. If you have code and it doesn't work, I can probably tell you why.

you haven't told me anything...

you basically threw your code at me and I told you that it won't work for what I'm doing so I asked if you had any ideas and to point me in the right direction not to write the code for me, so yeah...

I did point you in the right direction. Use a HashMap. Probably a HashMap<Integer[],ItemStack[]>, where you put the id/meta/amount args as the key and the outputs as the value.

I revisited your code and messed with it some more and got it semi working, but is there anyway to make it so that there needs to be more then one object in order for it to work?
