Capability implemented in tile entity but returning null

[HarryTechReviews]

I am using the item handler capability to create a custom furnace but although I have it implemented correctly (I think), the container reference to it returns null. Here's the code:

If you have any idea why this may return null, I would love to know. Thanks!

From the code it is more likely that you are passing in null for the tileentity parameter of ContainerElectricSinteringFurnace.

No the error specifies the line of the capability unfortunately

Oh my god ffs. You were right, I was using the local te instead of the global te variable. So frustrating. Thanks

Still doesn't work

What.

Why do you have a global variable?

Well post updated code, the new error report and which line it is crashing on.

You realize the thing you did doesn't fucking matter because you passed null to the constructor, right?

2 hours ago, HarryTechReviews said:

this.tileentity = tileentity;

IItemHandler handler = tileentity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, null);

both this.tileentity and tileentity are null. Changing tileentity to this.tileentity on the second line doesn't change that fact.

The only thing that could be causing a null pointer crash here would be "tileentity" you have to be passing null to the constructor.

I'm not, here it is in gui handler.

        if(ID == Reference.GUI_ELECTRIC_SINTERING_FURNACE) return new ContainerElectricSinteringFurnace(player.inventory, (TileEntityElectricSinteringFurnace)world.getTileEntity(new BlockPos(x,y,z)));
 

		if(ID == Reference.GUI_ELECTRIC_SINTERING_FURNACE) return new ContainerElectricSinteringFurnace(player.inventory, (TileEntityElectricSinteringFurnace)world.getTileEntity(new BlockPos(x,y,z)));

This can return null.

Same code for the other two gui and containers and they dont return null

Is the TileEntity actually being placed down where the block is? Is the TileEntity registered?

Yep, all other tile entities are the same but this one doesn't work

Could you post your Block class and parent classes.

The version of hasTileEntity you are using is deprecated. Deprecations exist for a reason, do not just ignore them.

Also, please, do not do this terrible vanilla furnace two-blocks-tile-entity hack.

OMFG thank you!
