Hello, i have a furnace recipe and i want it to output two items.

Can i use Math.random? How i do it?

Thanks

that wouldnt work that well, cause the furnace only has one output slot, therefore one item would be in the way for the other to appear. the only way to do so would be to make it only wok if that slot is empty, though that would be bad if its something the player needs to make a lot of, or you could make a different type of furnace like a slag furnace. i dont know how you would do those things, but i now that this will be a problem if you are going to use the vanilla furnace.

One output slot it's ok.

This is what i want to do:

I have a block of iron ore and i cook it. I could get an iron ingot or an iron nugget. That's why i said Math.random

If you create your own furnace: yes, fairly easy

If you use the vanilla furnace: yes, but it is tricky.

 

1) you could use a technique called ASM with Reflection to modify the vanilla code for Furnace.

2) you could use a tick event handler to change the output of the smelting recipe every tick to a random value; using GameRegistry.addSmelting().

3) you could make the smelting result a custom Item, and then when the ItemStack.updateAnimation is called, replace itself in the player's inventory by either the nugget or the ingot.

 

They are all fairly advanced and will take some fiddling to get right.  I would start with #2 personally.
