- [1.16.4]DataPack, Object.class, RegisterObject, Custom Fluid, How to?
  
  By Cratthorax · Posted 3 hours ago
  
  Don't be silly. A script kiddie is capable of basic copy pasting. I can't even do that. However, one more thing to add. How do you connect the registered FlowingFluidBlock, to your actual FluidBlock.class? I wasn't aware that you can actually customize the FlowingFluidBlock RegistryObject(or any other RegistryObject in that regard). Do it like that, and take info from the vanilla FluidBlocks how to build your FluidBlock.class accordingly: Change that... public static final RegistryObject<FlowingFluidBlock> OIL_BLOCK = MatLibRegister.BLOCKS.register("crudeoil", () -> new FlowingFluidBlock(() -> MatLibFluidOil.OIL_FLUID.get(), AbstractBlock.Properties.create(MATOIL) .doesNotBlockMovement().hardnessAndResistance(100f).noDrops())); ...to that... public static final RegistryObject<MyCustomFluidBlock> OIL_BLOCK = MatLibRegister.BLOCKS.register("crudeoil", () -> new MyCustomFluidBlock(() -> MatLibFluidOil.OIL_FLUID.get(), AbstractBlock.Properties.create(MATOIL) .doesNotBlockMovement().hardnessAndResistance(100f).noDrops())); ...and name your FluidBlock MyCustomFluidBlock.class. As far as I understand you do not want to extend to FlowableFluidBlock, but to FlowableFluid. I've yet to understand why, because in the past a fluid block, was still a block. It seems like it is now an "in between" thingy, or no longer a block at all. I hope someone of the wizards can spread some wisdom on that? And if it's just to ease the tinkering...👍 Edit: If someone wants more learning material, I'd recommend the TechReborn FlowableFluid.class, and their actual Fluid.class(Fabric only, so lots of adaptions needed, but good for getting an idea of structure), or PneumaticCraft(Forge). Notice they seem to be on 1.16.5 or even 1.17.1, but the code is compiling fine and dandy with minor adaptions(for 1.17.1 only?). You'd quickly find traces on how to "adapt" by highlighting methods/fields/etc., and open the declaration. Trouble starts really if references aren't public, because then you have to @Override in a custom.class. Which is something I've yet to learn as well. In the past, for 1.7(yes, that's 2013), it looked something like that:
