I have made the system similar to IRecipe and it's working. Abastro, thank you.

I'm sorry. I don't know. Thank you.

What's wrong with this code? When I right-click on crusher or compressor, Minecraft don't crash but world closes and I see "Fatal error: your connection terminated." Only compressor didn't work earlier but when I rewrite code to fix it the same problem became with crusher too.

There are three input slots and one output slot. There must be an item in every input slot for crafting.

There is a block with GUI in my mod. It works by the furnace principle but it has three slots for items instead of one. How do I need to create a recipe system for this block?
