[1.19.2] How to make your tree grow only on sand?

[Pherment]

I have a code own sapling block

public class BananSaplingBlock extends BushBlock {
    public static final IntegerProperty STAGE = BlockStateProperties.STAGE;
    private final AbstractTreeGrower treeGrower;

    public BananSaplingBlock(AbstractTreeGrower AbsTreeGrower, BlockBehaviour.Properties properties) {
        super(properties);
        this.treeGrower = AbsTreeGrower;
        this.registerDefaultState(this.stateDefinition.any().setValue(STAGE, Integer.valueOf(0)));
    }

    @Override
    protected boolean mayPlaceOn(BlockState state, BlockGetter level, BlockPos pos) {
        return state.is(BlockTags.SAND);
    }

    @Override
    public PlantType getPlantType(BlockGetter level, BlockPos pos) {
        return PlantType.DESERT;
    }
}

And have code configured features

public class KCConfiguredFeatures {
    public static final Holder<ConfiguredFeature<TreeConfiguration, ?>> BANAN_TREE =
            FeatureUtils.register("banan", Feature.TREE, new TreeConfiguration.TreeConfigurationBuilder(
                    BlockStateProvider.simple(KCBlock.BANAN_LOG.get()),
                    new StraightTrunkPlacer(5,6,3),
                    BlockStateProvider.simple(KCBlock.BANAN_LEAVES.get()),
                    new BlobFoliagePlacer(ConstantInt.of(2), ConstantInt.of(0), 4),
                    new TwoLayersFeatureSize(1,0,2)
            ).dirt().build());
}

I need my tree to grow only on sand. I read that you need to add a dirt method to the ConfiguredFeatures so that the tree grows on some specific block, but I do not understand what needs to be written in it. I would like to get help from you. And if there are errors in the code, then help fix them (And they can be)

I am no expert on trees, but I know the basics of how this works.

 

You don't show your PlacedFeature? PlacedFeatures have a list of PlacementModifiers.

The vanilla trees use PlacementUtils.filteredBlockBySurvival() where the Block parameter is the sapling.

This will call your sapling block's canSurvive(), see BushBlock.canSurvive() for the default implementation.

 

Also, it is recommended to use DeferredRegister rather than the vanilla registration methods.
