[1.9] NPE from PropertyEnum

[wehttam664]

Now, I'm not really sure why, but for some reason PropertyEnum.create(String, Class<T>) is returning null.

 

This is what I have:

  final PropertyEnum<FrameType> frameTypeProperty = PropertyEnum.create("type", FrameType.class);

  // ...

  @Override
  protected BlockStateContainer createBlockState() {
    System.out.println(frameTypeProperty);
    return new BlockStateContainer(this, frameTypeProperty);
  }

 

The console has null printed to it then the game crashes on an NPE in BlockStateContainer:99.

Why is it null?

Upon playing around a bit, I found that PropertyEnum.create(String, Class<T>) will work fine when called inside createBlockState() or in a static context, but not in object context.

 

Basically:

final static PropertyEnum<FrameType> frameTypeProperty = PropertyEnum.create("type", FrameType.class); // Works
final PropertyEnum<FrameType> frameTypeProperty = PropertyEnum.create("type", FrameType.class);        // Doesn't work.

 

Any thoughts, or should I go bug report this?

You should be declaring your Block properties as static - that's how every vanilla class does it, as well as every non-vanilla example that I have seen. Why it works that way, I couldn't tell you, but that's how it is so I wouldn't sweat it.

And this, kids, is why you don't define your variables where they're declared and use the constructor method for what it's for.
