Generate Custom Flower like Block

[Mightydanp]

I am trying to Generate a flower like block. right now it extends Blockbush. i seem to be having trouble with this line

 

          if (worldIn.isAirBlock(blockpos) && (!worldIn.provider.getHasNoSky() || blockpos.getY() < 255) && this.getBlock.canBlockStay(worldIn, blockpos, this.state))

 

this part makes my game crash this.getBlock.canBlockStay(worldIn, blockpos, this.state)

I have this and this works fine:

public WorldGenerator BUSH= new WorldGenBush((BlockBush) BlockClass.BLOCK);

@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkGenerator chunkGenerator, IChunkProvider chunkProvider) {
	switch (world.provider.getDimension()) {
	case -1:
		break;
	case 0:
		runGenerator(BUSH, world, random, chunkX, chunkZ, 7, 50, 120);
		break;
	case 1:
		break;
	}
}

private void runGenerator(WorldGenerator generator, World world, Random random, int chunk_X, int chunk_Z, int chancesToSpawn, int minHeight, int maxHeight){
	if (minHeight < 0 || maxHeight > 256 || minHeight > maxHeight){
		throw new IllegalArgumentException("Illegal Height Arguments for WorldGenerator");
	}
	int heightDiff = maxHeight - minHeight + 1;
	for (int i = 0; i < chancesToSpawn; i++); {
		int x = chunk_X * 16 + random.nextInt(16);
		int y = minHeight  + random.nextInt(heightDiff);
		int z = chunk_Z * 16 + random.nextInt(16);
		generator.generate(world, random, new BlockPos(x, y, z));
	}
}

}

I just tried this and i get the same Errors

Please actually post your crash-log. Without that, we have no clue what's actually happening.

spawnTwigs(ModBlocks.twigs, world, random, chunkX, chunkZ, 7);

You never assign a value to IWorldGenTwigs#state, so it is null and Java throws an NPE when it is referenced.

 

While not the cause of the problem IWorldGenTwigs should be called WorldGenTwigs, as it is a class, not an interface.

i have tried to set the blocks state with this.getBlock.getDefaultState() and this.getBlock.canBlockStay(worldIn, blockpos, this.getBlock.getStateFromMeta(0)

 

neither of them work and it gives the same exact crash

[Leviathan143]

You are doing it wrong then, show that code.

[Mightydanp]

if (worldIn.isAirBlock(blockpos) && (!worldIn.provider.getHasNoSky() || blockpos.getY() < 255) && this.getBlock.canBlockStay(worldIn, blockpos,this.getBlock.getDefaultState() ))

[Leviathan143]

Have you set a default state for BlockTwigs?

[Mightydanp]

yes i have

[Mightydanp]

Any help ? i registed my block state of my block already. it still gave me the error

[Leviathan143]

Are you sure it's exactly the same error as the intial one? Post a new log.

Dude, seriously. The first line is the most important one: it tells us/you what the error is.  The second line is the second most important: it tells us/you where the error is.  We need both.
