I would like my tanks emit the same amount of light of the fluid inside, but this is the result:

 

The code from the block:

    
    @Override
    public int getLightValue(IBlockState state, IBlockAccess world, BlockPos pos) {
        if (state.getValue(TYPE) == TankType.GLASSES) {
            TileEntity te = world.getTileEntity(pos);

            if (te instanceof UpgCtileentityFluidTank)
                return ((UpgCtileentityFluidTank) te).getFluidLight();
        }
        return super.getLightValue(state, world, pos);
    }

 

And from the tile entity:

    public int getFluidLight() {
        if (tank.getFluid() == null)
            return 0;
        return tank.getFluid().getFluid().getLuminosity(tank.getFluid());
    }

 

Can anyone help me please?

On the client side the function returns the same value of the server side.

With the debugger, on client thread and on server thread the return value is always the same, 15 in this case.

Yes I cause a block update when there is a change in the fluid level.

I know...on 1.7.10 it works perfectly, and I think I do similar things...

To cause a block update in the tileentity I call this:

worldObj.notifyBlockUpdate(pos, blockState, blockState, 3);

 

Is it correct?

World has no markBlockForUpdate method...

All my tanks extend this class:

I have changed the function in this way:

    @Override
    public void onDataPacket(NetworkManager net, SPacketUpdateTileEntity packet) {
        readFromNBT(packet.getNbtCompound());
        IBlockState blockState = worldObj.getBlockState(pos);
        if (blockState != null)
            worldObj.notifyBlockUpdate(pos, blockState, blockState, 3);
    }

But I have the same behavior as before...

The strange thing is that if I put another light source such as a torch, everything is fine, even when I take off the torch and let only my tank...

Edit:

After I do that, if i remove also the tank the light remains...

I wrote a block with its tileentity for just testing the lighting and I get the same result as with tanks...

Try calling markBlockRangeForRenderUpdate instead of the block notify method in your onDataPacket method.  You want to force a rebuild of the scene, which I am guessing may not happen if the block states updates, on their own, don't affect rendering.

 

This works for me in a similar case where block color is stored in a tile entity and this information tends to show up at the client after the scene is already rendered.

 

It may also be needed in the client-side onLoad() method.

It doesn't work...

I use the method in this way:

BlockPos minPos = pos.add(-20, -20, -20);
BlockPos maxPos = pos.add(20, 20, 20);
worldObj.markBlockRangeForRenderUpdate(minPos, maxPos);

It's correct?

Yes, but range should not need to be that big.

 

What is in BlockUpgC and what does your model look like? Does this thing have multiple render layers?

 

I've also seen similar weirdness when trying to create blocks with multiple render layers where one of the layers is fully lit and others not.

 

20 is a random number just to see if it works.
