[1.11] playSound crashes game. Null pointer exception in PositionedSoundRecord class

[MSpace-Dev]

Hey everyone,

 

Having trouble loading my custom sound using the playSound method in code. My sound loads completely fine when I use /playsound in-game, but as soon as the playSound method gets called, the game crashes. Really not sure why. I should have everything registered correctly, as the sound does actually play when using commands.

 

Common Proxy:

public class CommonProxy {
    @Mod.EventHandler
    public void preInit(FMLPreInitializationEvent event){
        RegistryEventHandler.registerSounds();
    }
}

 

Registry Event Handler: ( Courtesy of @Choonster TestMod3 code )

@Mod.EventBusSubscriber
public class RegistryEventHandler {
    public static SoundEvent infused_log_ambient;

    public static void registerSounds() {
        infused_log_ambient = registerSound("infused_log_ambient");
    }

    private static SoundEvent registerSound(String sound) {
        Utils.getLogger().info(sound + " loaded");
        final ResourceLocation soundID = new ResourceLocation(Reference.MODID, sound);
        return GameRegistry.register(new SoundEvent(soundID).setRegistryName(soundID));
    }
}

 

Play Sound called in this class:

public class ItemSpiritBase extends ItemBase {


    public ItemSpiritBase(String name) {
        super(name);
    }

    protected void conversionDisplay(World world, BlockPos pos) {
        if(world.isRemote) {
            world.playSound(pos.getX(), pos.getY(), pos.getZ(), RegistryEventHandler.infused_log_ambient, SoundCategory.BLOCKS, 1.0f, 1.0f, false);
        }
    }
}

 

conversionDisplay() is called from here:

@Override
    public EnumActionResult onItemUse(EntityPlayer player, World worldIn, BlockPos pos, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) {
        Utils.getLogger().info("Used item!");
        if(worldIn.getBlockState(pos) == Blocks.LOG.getDefaultState() || worldIn.getBlockState(pos) == Blocks.LOG2.getDefaultState()) {
            Utils.getLogger().info("Log test worked!");
            conversionDisplay(worldIn, pos);
            worldIn.setBlockState(pos, ModBlocks.zombie_infused_log.getDefaultState());
        }

        return super.onItemUse(player, worldIn, pos, hand, facing, hitX, hitY, hitZ);
    }

 

Sooo yeah, game crashes as soon as I R-click on the MC logs. Definitely because of the playSound() method.

Ah, alright. (I was calling registerSounds from my Common Proxy Class)

[MSpace-Dev]

Awesome, got it working fine now. Thank you.

 

    public static SoundEvent infused_log_ambient;
    private static final ResourceLocation infusedLogAmbientRL = new ResourceLocation(Reference.MODID, "blocks.infused_log_ambient");

    @SubscribeEvent
    public static void registerSounds(RegistryEvent.Register<SoundEvent> event) {
        infused_log_ambient = new SoundEvent(infusedLogAmbientRL).setRegistryName(infusedLogAmbientRL);
        registerSound(infused_log_ambient, event);
    }

    private static void registerSound(SoundEvent soundID, RegistryEvent.Register<SoundEvent> event) {
        Utils.getLogger().info(soundID + " loaded");
        event.getRegistry().register(soundID);
    }
