Hello,

so after my last post I succesfully created a void dimension, only problem is that if I try to teleport to it (Using an item that has an onItemRightClick event that executes player.ChangeDimension(2)) the game freezes in the loading screen and gives me an NullPointerException.

However if I were to restart the game I'd appear in the dimension totally fine! 

 

Here is the error:

And my registry code

@Mod.EventBusSubscriber(modid = Reference.MODID)
public class Dimensions {

    public static int ID_TARDIS = 2;
    public static final String TARDIS_NAME = "tardis";
    public static DimensionType TARDIS_DIM = DimensionType.register(TARDIS_NAME, "_"+TARDIS_NAME, ID_TARDIS, WorldProviderTardis.class, true);
    public static WorldType WT_TARDIS = new WorldTypeTardis();

    private static List<Biome> BIOMES = new ArrayList<>();

    public static final void registerDimensions() {

        DimensionManager.registerDimension(ID_TARDIS, TARDIS_DIM);

    }

}

 

how looks the line of code that the NPE points to?

Sorry for the late reply, but heres the line in the VortexManipulatorClass

player.changeDimension(Dimensions.ID_TARDIS);
