Creating a new dimension and immediatelly putting some blocks in it

[McJty]

Hi all, I'm trying to create a new dimension and want to put some blocks in that dimension right away. I have the following code:

 

        int id = DimensionManager.getNextFreeDimId();

        DimensionManager.registerProviderType(id, GenericWorldProvider.class, false);

        DimensionManager.registerDimension(id, id);

 

        World newWorld = WorldProvider.getProviderForDimension(id).worldObj;

 

 

However the newWorld is null. How can I make sure that my new dimension has a valid world to use?

 

Thanks,

How can I trigger world generation? I haven't seen any tutorials or examples that demonstrate how to do that.

 

Thanks,
