Let's start with a basic example by extending SaplingBlock.First create a class that extends SaplingBlock.
<code>public class ExampleSapling extends SaplingBlock{}</code>

After that you can insert the constructor. It must call super with the Parameters :

That means we need to make a Tree for ourselves, but more on that in a bit.<br>
If you want to have the Sapling be placeable on your own Mods Block, you need to override <code>isValidGround</code> and make your own additions to the vanilla provided Blocks. I recommend making a <br><code>private static final List<Block> validBlocks = ImmutableList.of(Blocks block...)</code> to add Blocks to the List of possible Blocks.<br>
If you have that, your function could look like : <br>

Now onto making the Tree for your Sapling.<br>
Start by making a <code>class</code> that extends <code>Tree</code> : <br>
Now onto making the Tree for your Sapling.
<code>public class ExampleTree extends Tree </code> <br>
This <code>class</code> will only contain one <code>function</code> which is : <br>
Start by making a <code>class</code> that extends <code>Tree</code> :
<code>protected ConfiguredFeature<BaseTreeFeatureConfig, ?> getTreeFeature(Random randomIn, boolean largeHive)</code><br>
As you can see, this function requires to return a ConfiguredFeature<BaseTreeFeatureConfig, ?>. This will be the Tree that is Placed in the World. <br>
<code>public class ExampleTree extends Tree </code>
The <code>ConfiguredFeature<BaseTreeFeatureConfig, ?><code> will look sth like this : <br>
This <code>class</code> will only contain one <code>function</code> which is :
public static final ConfiguredFeature<BaseTreeFeatureConfig, ?> EXAMPLETREEFEATURE = <br>
<code>protected ConfiguredFeature<BaseTreeFeatureConfig, ?> getTreeFeature(Random randomIn, boolean largeHive)</code>
Feature.TREE.withConfiguration(<br>
As you can see, this function requires to return a ConfiguredFeature<BaseTreeFeatureConfig, ?>. This will be the Tree that is Placed in the World.
new BaseTreeFeatureConfig.Builder(<br>
The <code>ConfiguredFeature<BaseTreeFeatureConfig, ?></code> will look sth like this :
new SimpleBlockStateProvider(BlockInit.EXAMPLE_WOOD.get().getDefaultState()),<br>
<syntaxhighlight lang="java">
new SimpleBlockStateProvider(BlockInit.EXAMPLE_LEAVES.get().getDefaultState()),<br>
public static final ConfiguredFeature<BaseTreeFeatureConfig, ?> EXAMPLETREEFEATURE =
new BlobFoliagePlacer(FeatureSpread.func_242252_a(2), FeatureSpread.func_242252_a(0), 3),<br>
Feature.TREE.withConfiguration(
new StraightTrunkPlacer(4, 2, 0),<br>
new BaseTreeFeatureConfig.Builder(
new TwoLayerFeature(1, 0, 1)<br>
new SimpleBlockStateProvider(BlockInit.EXAMPLE_WOOD.get().getDefaultState()),
).setIgnoreVines().build());<br>
new SimpleBlockStateProvider(BlockInit.EXAMPLE_LEAVES.get().getDefaultState()),
After we have our ExampleTree we need to register it. This is done via 2 functions : <br>
new BlobFoliagePlacer(FeatureSpread.func_242252_a(2), FeatureSpread.func_242252_a(0), 3),
new StraightTrunkPlacer(4, 2, 0),

).setIgnoreVines().build());

After we have our ExampleTree we need to register it. This is done via 2 functions :
<syntaxhighlight lang="java">
public static void registerTrees() {
register("example_tree", EXAMPLETREE);
register("example_tree", EXAMPLETREE);
}
}
<code><br>

and also the function <code>register</code> :

If you have everything setup, call registerTrees() in FMLCommonSetupEvent.<br>

Back to the Sapling. Your constructor can now be completed by putting the Tree we just registered as the first super parameter and the Properties as the second parameter :

Also in your ExampleTree class, instead of null, the function now should return your TreeFeature : <br>

Now register the Sapling like any other Block and it should be able to be placed and grow with the correct Tree.
