[1.6.4][SOLVED]Double output furnace

[Nicba1010]

Hi fellow modders,

me and my friend Dautor are making a mod,

and it needs to include a custom furnace with 2,3 and 4 outputs.

All different ones to be clear. We have made the code

for the basic 1 output furnace, and have experimented

with the 2. output slot but could not get it to work.

The 1 output works great!

Thanks for reading this!(And if u help, for helping too OFC  )

Sincerely Dautor and Nicba1010

i've seen sth about dual hashmaps.

any1 know how that would go

I solved it myself. I think I may gonna make a tutorial!
