Is it cause I need to register something? Maybe tree worldgen needs registering??

Yes you need to register WorldGenerators.

[trollworkout]

But how do I register it?

 

The GameRegistry.RegisterWorldGenerator only registers IWorldGenerator and not WorldGenerator for my custom tree gen.

 

Seems other mods don't register their custom tree gen.

 

I'm thinking my problem may be somewhere else maybe my grow function in my sapling is broken.

Doesn't WorldGenAbstractTree implement IWorldGenerator and you never call the generation method you just create a new instance then never do anything.

[trollworkout]

WorldGenAbstractTree extends WorldGenerator

 

Nope it implements WorldGenerator not IWorldGenerator.

 

 

Whatever code I have up there it does not bonemeal and will not grow ever. There's some issue somewhere. I have a feeling the sapling is broken.

[Animefan8888]

WorldGenAbstractTree extends WorldGenerator

 

Nope it implements WorldGenerator not IWorldGenerator.

And WorldGenerator implements IWorldGenerator

Here I meant in your growTreeMethod(...).

[Animefan8888]

And WorldGenerator implements IWorldGenerator

No, it doesn't.

Really? Wow, is IWorldGenerator just provided by forge as a better alternative? I have never looked at WorldGenerator as I have not needed it.

[larsgerrits]

IWorldGenerator

is added by Forge to make custom world generation easier. Vanilla code is generated in

BiomeDecorator

, and the custom generation is called from

Chunk#populateChunk

.

Good to know. Still shows that I have much more to learn.

[trollworkout]

WorldGenerator does not implements or extends anything. IWorldGenerator and WorldGenerator are not compatible.

 

 

So how do I fix my custom tree?

[trollworkout]

I figured it out guys.  I was right my sapling was incorrect.

 

Gen tree was wrong. I fixed it like so

 

   public void generateTree(World worldIn, BlockPos pos, IBlockState state, Random rand)
    {
        if (!net.minecraftforge.event.terraingen.TerrainGen.saplingGrowTree(worldIn, rand, pos)) return;
	WorldGenerator worldgenerator = new WorldGenTree(true, false, type);

        IBlockState iblockstate2 = Blocks.AIR.getDefaultState();
        worldIn.setBlockState(pos, iblockstate2, 4);
        
        if (!worldgenerator.generate(worldIn, rand, pos.add(0, 0, 0)))
        {
        	 worldIn.setBlockState(pos, state, 4);
        }
    }

 

 

Note the

        IBlockState iblockstate2 = Blocks.AIR.getDefaultState();

        worldIn.setBlockState(pos, iblockstate2, 4);

       

        if (!worldgenerator.generate(worldIn, rand, pos.add(0, 0, 0)))

        {

        worldIn.setBlockState(pos, state, 4);

        }

 

seems like you need to set the state of air block to 4 before you can spawn the tree.
