I'm almost sure the problem comes from the way i write my items in TileEntity, but whenever I try another method my items just disseapear when I log out ^^

 

if anyone can help me that would be nice

thank in advance

You should check for null before casting. What does InventoryHelper#dropInventoryItems do?

It's nice to try to help me

but has i spent 10 hours you can guess i already tried a lot of things and if you aren't more precise in your explanations i'll just revolve around the problem.

 

I deleted the parts you dislike, but if i remove NonNullList from my tile entity (and everything assiociated) i just get a new problem in my FakeBlock

FakeBlock : the problem is there

@Override
   public void breakBlock(World worldIn, BlockPos pos, IBlockState state)
   {
       FakeBlockTileEntity tileentity = (FakeBlockTileEntity) worldIn.getTileEntity(pos);
       InventoryHelper.dropInventoryItems(worldIn, pos, tileentity);
       super.breakBlock(worldIn, pos, state);
       
    }

Now it says "The method dropInventoryItems(World, BlockPos IInventory) in the type InventoryHelper is not applicable for the arguments (World, BlockPos, FakeBlockTileEntity).

That's why I used NonNullList in the first case.

More precision

[Siqhter]

In the breakBlock method, loop through the inventory's slots. Create a new EntityItem in the for loop and then call spawnAsEntity. I think InventoryHelper#dropInventoryItems wants an IInventory, which probably won't work in your case. This is somewhat how I did it, and I use ItemStackHandler.

I guess i'll never know why "dropitem" didn't work, but as lon as my items still "dropped" i don't really care ^^

 

Have a nice day

You can edit your original post and add “[SOLVED] “ to the title.

 

Here is an example of how I drop my items https://github.com/Cadiboo/WIPTechAlpha/blob/fb5883e9d76ef0361ec1ebbcb9c508611dd2ef6b/src/main/java/cadiboo/wiptech/capability/inventory/ModItemStackHandler.java#L23-L35

You still need to

- Not use ITileEntityProvider: It is legacy vanilla code, simply override hasTileEntity and createTileEntity.

- Not use IHasModel: It is a stupid way of registering things that makes you write the exact same lines of code for ever class, it is unneeded and a better result can be achieved with 1 single line of code.

- Check for null before using the tile entity you get from world#getTileEntity

- Check that the tile entity you get from world#getTileEntity actually is an instance of your tile entity before you cast it (when the block is replaced, a structure is loaded on top of it, commands like /fill, /clone or /setblock are used, or even if the server is just overloaded, it might not be an instance of your tile entity)
