I'm making a mod, and have created a hopper-like block. I  used @Override to turn it into a tile entity. It all works, you can put items in it, and hoppers underneath take them out. The problem is that when I break it in creative, it breaks, but the items in it disappear. In survival, it doesn't break at all. It's make the animation, and a new one will immediately appear. Is there an Override command to stop this from happening? It's also a custom block, so it has it's own voxel shape. Here's my code:

You have to override the onReplaced method and tell your block to drop the contents of its tile entity when replaced or broken...look at vanilla chest, hopper etc. for examples on how to handle container blocks

Where would I find the vanilla files for a hopper or chest? I can't figure out what any of the stuff in the minecraft folder means

 

Found it

Ok so now when I have this, and when I break it in creative the items inside drop. In survival, it still refuses to break. Any idea why?

@Override
public void onReplaced(BlockState state, World worldIn, BlockPos pos, BlockState newState, boolean isMoving) {
    if (!state.isIn(newState.getBlock())) {
        TileEntity tileentity = worldIn.getTileEntity(pos);
        if (tileentity instanceof HopperTileEntity) {
            InventoryHelper.dropInventoryItems(worldIn, pos, (HopperTileEntity)tileentity);
            worldIn.updateComparatorOutputLevel(pos, this);
        }

        super.onReplaced(state, worldIn, pos, newState, isMoving);
    }
}

Edit: Using haste 155, or instamine, I can break it. Obviously, you can't get this normally, but it does break. This is in survival

Why do you have this?

.func_235859_g_()

For some reason, SetRequiresTool doesn't work, but that's the code that does it

 

Alright so I think that the problem is that the tile entity is replacing itself every tick. This is why it'll break in creative and instamine, because it's destroyed in less than a tick

Any way to fix that?

 

Remove 

.func_235859_g_()

This is preventing yuor block getting destroyed.

Oh okay thanks
