I registered my IRecipe instead of a stick recipe, but in the recipe book it's empty, the stick icon itself is there. As you can see in the screenshot, the recipe icon is there, but supposedly I can do it, although I have no resources. When you click on the crafting icon, there is no reaction. How to make a normal recipe in the book?

Thank you diesieben07, Draco18s

I've seen it, but how do I use it in an ArrayList or List variable?

Sorry, perhaps, this question already someone asked and on him someone responded, but I have very little information about this, only for old versions of. The question in the topic title. P.S. sorry for my English again.

Thanks

I want the player to not be able to craft the item if the condition(I don't want to say what condition) is wrong. I want other players to be able to make an item if they have a true condition.

Nothing bad happened, I saw errors in the console and immediately fixed it by checking the block. if (!world.isRemote && world.getBlockState(blockPos).getBlock() == Blocks.PLANKS) { if (world.getBlockState(blockPos).getValue(BlockPlanks.VARIANT) == BlockPlanks.EnumType.OAK) { world.setBlockState(blockPos, NTCBlocks.NTC_LIGHTWOOD.getDefaultState()); } }

I made this code and it works, thanks again! if (!world.isRemote && world.getBlockState(blockPos).getValue(BlockPlanks.VARIANT) == BlockPlanks.EnumType.OAK) { world.setBlockState(blockPos, NTCBlocks.NTC_LIGHTWOOD.getDefaultState()); }

Thanks so much!

Look in the source code of the game?

Hi, I don't speak English very well! How to check oak boards? I have this code, but it skips all kinds of planks. | I just need to check the oak planks. \ / if (!world.isRemote && world.getBlockState(blockPos).getBlock() == Blocks.PLANKS) { world.setBlockState(blockPos, NTCBlocks.NTC_LIGHTWOOD.getDefaultState()); }
