After I coded corresponding codes for a custom furnace, the program always crashes and console showed such crash report. I really appreciate it if someone can handle my confusion

 

crash-2019-04-12_17.53.14-client.txt

and these are TestFurnace and EventSubscriber class

TestFurnace.java

EventSubscriber.java

Why did you upload your code as files here? Use github.

 

Quote

public class TestFurnace extends Block implements ITileEntityProvider

Don't implement ITileEntityProvider, this interface is not needed. Just override Block#hasTileEntity and Block#createTileEntity

 

You don't need the setState method. Just override TileEntity#shouldRefresh.

 

The fact that you are using InventoryHelper.dropInventoryItems makes me suspicious of your TileEntity implementing IInventory. Never implement IInventory, use capabilities instead.

 

@Override
	public EnumBlockRenderType getRenderType(IBlockState state) 
	{
		return EnumBlockRenderType.MODEL;
	}

Why? Block#getRenderType already returns MODEL.

 

as for your issue:

You have never told the block state container that your block has the BURNING property associated with it in Block#createBlockState. You must put all the properties you wish to use there.

 

Additionally you are not (de)serializing your BURNING property in getStateFromMeta nor getMetaFromState. You must do it in order for the property to persist.
