Hi,

I'm trying to make a new SoundType for my blocks, but whatever I do I recieve an "java.lang.NullPointerException: Registry Object not present" error. I'm not sure what's exatly going on, maybe you need to assign sounds later or something?

Maybe there is some sort of trick to do it that I'm not aware of? 

Here is the code and the log:

You call a method here, but the code you've shown does not contain this method.

What do you mean? You are talking about the register() methode? It is already implemented in DefferedRegister class. Other DefferedRegisters like Blocks or Items worked this way

ModBlocks.BLOCKS.register(modEventBus);

 

And also the problem appears only when I try to create a SoundType object. If I register the sounds and don't use them, they work (I can use playsound command inside minecraft and it works fine)

Sound events are registered after blocks, so I believe that's part of the issue. One option would be to extend SoundType and override its get methods to make them access RegistryObject entries as needed instead of on initialization. Feels like there should be a cleaner solution though...

That's my thought, too.

I hope there is. I feel like it is a common thing to do for modders, to add new blocks with new sounds, so it would be nice to have a easier methode to implement it.

Use the solution I posted, it's a fine workaround for the time being until Forge makes an official fix.

Spoon-feeding code is frowned upon on these forums, but I can try rewording what I already mentioned in a more tutorial-esque way:

  1. Extend SoundType and override all of its "get sound" methods.
  2. In the constructor, replace the parameters of SoundEvent with RegistryObject<SoundEvent>. You'll also need to place them is fields, obviously.
  3. Put null when the super constructor wants SoundEvent objects, we won't be using them anyways.
  4. In the overridden methods, return RegistryObject#get for each of your corresponding objects.

If any of that was confusing, you may need to spend some more time learning Java before you start modding.
