GenerateStructures

Hi there,

I am currently working on generating structures in Minecraft. 

I was creating a method called generateStructure which would have made the TemplateManager etc. When doing this it caused an error which said "worldServer" cannot be resolved. I am pretty stumped on this because I am pretty new to minecraft modding and I do not know what i could replace the worldServer with. This entire class is below.

	public WorldGenStructure(String name){
		this.structureName = name;
	}
	
	@Override
	public boolean generate(World worldIn, Random rand, BlockPos position) {
		this.generateStructure(worldIn, position);
		return true;
	}
	
	public static void generateStructure(World world, BlockPos pos){
		MinecraftServer mcServer = world.getMinecraftServer();
		TemplateManager manager = worldServer.getStructureTemplateManager();
		ResourceLocation location = new ResourceLocation(Reference.MOD_ID, structureName);
		Template template = manager.get(mcServer, location);
		
		if(template != null){
			IBlockState state = world.getBlockState(pos);
			world.notifyBlockUpdate(pos, state, state, 3);
			template.addBlocksToWorldChunk(world, pos, settings);
