I recently started creating a test example for a six way block and tried to waterlog it. I then tried to extending it to all fluids but not only would it render, it would also throw an error if the fluid block being read wasn't the source. I'm not sure what to do to allow any fluid at any level to render properly and work correctly when the block contains a fluid. I know that it has something to do with Block#getFluidState however I'm not sure why.

 

Block class:

    public static final BooleanProperty HAS_FLUID = BooleanProperty.create("has_fluid");

                worldIn.getPendingFluidTicks().scheduleTick(pos, fluidStateIn.getFluid(), fluidStateIn.getFluid().getTickRate(worldIn));

state.getFluidState()

Your code is looping. Its infinite recursion. Your getFluidState method calls BlockState#getFluidState which calls your method again.

You know I feel like such an idiot sometimes. But then comes the problem of having multiple fluids inside the block. Do I need to create a state for each fluid? If so, then would it require to have a state for the flowing version and the source version? What would come about for modded fluids then as well? I don't really see a way to have a state for each fluid in the game dynamically.

After changing my code to match Minecraft's style, there seems to be no support for liquid containers other than water. If that's the case, how would you get other liquids to render inside the block? It seems like this system was only made for one instance and no other case.

You'll probably have to wait until Forge's fluid system rewrite is completed, I'm pretty sure the Vanilla system only really supports water.
