I want to check if a block at a given position in the world is a full (source) block of fluid or if it is flowing. I thought I could simply check if the block is Blocks.flowing_water or Blocks.flowing_lava, but I must be misunderstanding something because every water block on screen in this screenshot is reported as BlockStaticLiquid rather than BlockDynamicLiquid. As a side question, would it be any different for forge fluid blocks compared to vanilla liquids?

 

Edit: I'm an idiot and didn't include the screenshot

For

BlockLiquid

, metadata 0 is a source block.

 

Forge's Fluid system doesn't specify that fluids must have a source block (

BlockFluidClassic

does, but

BlockFluidFinite

doesn't) , but

IFluidBlock#drain

should return a

FluidStack

with

FluidContainerRegistry.BUCKET_VOLUME

as the amount if a bucket can be filled from the block. Make sure you call

IFluidBlock#canDrain

first and call

IFluidBlock#drain

with

false

as the

doDrain

argument.

(That process is important, as meta:0 for infinite fluids is a source block, but meta:0 for finite fluids is none!)
