Hello, I made the liquid, but after loading the game and entering the world, I noticed that the fluid is the same color as regular water, although she had to change the color. My code:

[spoiler=BlockOil]

public class BlockOil extends BlockFluidClassic
{
    public BlockOil(Fluid fluid, String name)
    {
        super(fluid, Material.WATER);
        setRegistryName(name);
        setUnlocalizedName(name);
        setCreativeTab(TabsHandler.TAB_FLUIDS);
    }

    @Override
    public void onBlockAdded(World world, BlockPos pos, IBlockState state)
    {
        super.onBlockAdded(world, pos, state);
        mergerFluids(pos, world);
    }

    @Override
    public void neighborChanged(IBlockState state, World world, BlockPos pos, Block neighborBlock)
    {
        super.neighborChanged(state, world, pos, neighborBlock);
        mergerFluids(pos, world);
    }

    private void mergerFluids(BlockPos pos, World world)
    {
        for(EnumFacing facing : EnumFacing.values())
        {
            Block block = world.getBlockState(pos.offset(facing)).getBlock();
            if(block == Blocks.WATER || block == Blocks.FLOWING_WATER)
            {
                world.setBlockState(pos.offset(facing), Blocks.STONE.getDefaultState());
            }
            else if(block == Blocks.LAVA || block == Blocks.FLOWING_LAVA)
            {
                world.setBlockState(pos.offset(facing), Blocks.BRICK_BLOCK.getDefaultState());
            }
        }
    }
}

        super("fluidOil", new ResourceLocation("blocks/water_still"), new ResourceLocation("blocks/water_flow"));
    }
    
    @Override
    public int getColor()
    {
        return 0xFF00FF00;
    }

I have no experience with fluids, but might this have anything to do with it? Try making a custom Texture.

Why? I use the vanilla texture minecraft. Yes, and I'm more interested in the option of repainting, but then you can't leave a not working code))

Am I understanding something wrong? If your problem is, that the texture is blue and not black or whatever, you might want to not use the vanilla texture (which is blue). Just create a new texture. Then again, I might not be understanding what the problem is. Mind showing some pictures?

So, look, it's my fluid: http://prntscr.com/e9yyi9 , I pointed out in the code, what texture/fluid should be green, but in the game I see the same texture as the water. For a basis I took the code from the repository MinecraftForge github, where everything works as it should, but the same code(without instance in the class block and liquid) does not work properly.

public class FluidOil extends Fluid
{
    public FluidOil()
    {
        super("fluidOil", new ResourceLocation("blocks/water_still"), new ResourceLocation("blocks/water_flow"));
    }

    //this method will paint the texture of water, in the specified color.
    @Override
    public int getColor()
    {
        return 0xFF00FF00;
    }
}

 

Try this:

public int getColor() {
return 0xDD9E881E;
}

Not working at all strange. In debug mode the method itself works, but the return nothing sends.

New problem, I set its texture to the liquid and nothing happens, as was usual with the liquid texture of water and left.
