[1.14.4] Custom grass block behaviours

[abdmoh123]

I am creating a custom netherrack grass block (warped nylium)

I would like the block to turn into netherrack after placing a block on top.

I would also want grass and flowers to be placeable on it.

Also, any ideas on how to make it spreadable?

 

So far, I got the block to register with textures and everything, but I could find any tutorials on getting grass functionality for it

 

Thanks

 

Here is the block's class so far:

public class WarpedNylium extends GrassBlock {
    public WarpedNylium() {
        super(Properties.create(Material.ORGANIC)
                .sound(SoundType.STONE)
                .hardnessAndResistance(0.4F)
                .harvestTool(ToolType.PICKAXE)
        );
        setRegistryName("warped_nylium");
    }
}

Hi

 

I very much doubt you'll find a specific tutorial for this, I think you'll probably have to spend some time understanding the vanilla code.  Some of the key words to help your search:

Block.canSustainPlant()

BushBlock

GrassBlock.grow()

SpreadableSnowyDirtBlock.tick()

I found GrassBlock.grow() and GrassBlock.canGrow()

The first one returns a void datatype and the second one returns a boolean datatype

 

I overridden the second method to return true, but there was no change

Here is the code now:

public class WarpedNylium extends GrassBlock {
    public WarpedNylium() {
        super(Properties.create(Material.ORGANIC)
                .sound(SoundType.STONE)
                .hardnessAndResistance(0.4F)
                .harvestTool(ToolType.PICKAXE)
        );
        setRegistryName("warped_nylium");
    }

    @Override
    public boolean canGrow(IBlockReader worldIn, BlockPos pos, BlockState state, boolean isClient) {
        return true;
    }
}

 

I am unsure on how to override the grow() method, since it looks complicated:

public void grow(World worldIn, Random rand, BlockPos pos, BlockState state) {
   BlockPos blockpos = pos.up();
   BlockState blockstate = Blocks.GRASS.getDefaultState();

   for(int i = 0; i < 128; ++i) {
      BlockPos blockpos1 = blockpos;
      int j = 0;

      while(true) {
         if (j >= i / 16) {
            BlockState blockstate2 = worldIn.getBlockState(blockpos1);
            if (blockstate2.getBlock() == blockstate.getBlock() && rand.nextInt(10) == 0) {
               ((IGrowable)blockstate.getBlock()).grow(worldIn, rand, blockpos1, blockstate2);
            }

            if (!blockstate2.isAir()) {
               break;
            }

            BlockState blockstate1;
            if (rand.nextInt(8) == 0) {
               List<ConfiguredFeature<?>> list = worldIn.getBiome(blockpos1).getFlowers();
               if (list.isEmpty()) {
                  break;
               }

               blockstate1 = ((FlowersFeature)((DecoratedFeatureConfig)(list.get(0)).config).feature.feature).getRandomFlower(rand, blockpos1);
            } else {
               blockstate1 = blockstate;
            }

            if (blockstate1.isValidPosition(worldIn, blockpos1)) {
               worldIn.setBlockState(blockpos1, blockstate1, 3);
            }
            break;
         }

         blockpos1 = blockpos1.add(rand.nextInt(3) - 1, (rand.nextInt(3) - 1) * rand.nextInt(3) / 2, rand.nextInt(3) - 1);
         if (worldIn.getBlockState(blockpos1.down()).getBlock() != this || worldIn.getBlockState(blockpos1).func_224756_o(worldIn, blockpos1)) {
            break;
         }

         ++j;
      }
   }

}

 

Thanks for the help

 

Edit:

I found the canSustainPlant() method but I think it could be deprecated, correct me if I am wrong
