How can I get the angle from where a sound was played?


Recommended Posts

Hello, I am trying to create a mod which shows the angle of a sound. I mean, if a chicken cackles in your left, I want to be able to get exactly the angle of the chicken.

Sorry for the drawing but I think it makes an idea of what I want.

 

@SubscribeEvent
public static void soundAngle(PlaySoundEvent e){
    ISound sound = e.getResultSound();
}

	@SubscribeEvent
	public static void soundAngle(PlaySoundEvent e){
	    ClientPlayerEntity player = Minecraft.getInstance().player;
	    if(player != null) { //the event also triggers in the main menu, so this avoids crash
			ISound sound = e.getResultSound();
	    	double x = sound.getX() - player.getPosX(); //gets the position relative to the player
	    	double y = sound.getZ() - player.getPosZ();
	    	double angle = Math.atan2(y, x);			//converts two sides of a rectangle to an angle given in radians
	    	player.sendChatMessage(String.valueOf(angle));
	    }
	}

Something like this should work. In this code you get the angle relative to the world and not the player.

that's basically it, though a short instruction would be better that working code.

and be careful about sides or your mod will crash multiplayer games.

Well if you (Tatuck) want to know more about the subject, look into trigonometry. (in case you're not familiar with it)

I think you can find many good explanations on the internet, maybe videos will be helpfull. I think you can learn the basics of trigonometry pretty fast and then you can do so much more with 3D coordinates.

    • I'm currently trying to make a new cauldron-type block, and I'm having difficulty implementing blockstates. Here's the relevant part of the alchemical cauldron's code:   public class AlchemicalCauldronBlock extends Block { public static final IntegerProperty LEVEL = IntegerProperty.create("level", 1, 3); private static final VoxelShape INSIDE = box(2.0D, 4.0D, 2.0D, 14.0D, 16.0D, 14.0D); protected static final VoxelShape SHAPE = VoxelShapes.join(VoxelShapes.block(), VoxelShapes.or(box(0.0D, 0.0D, 4.0D, 16.0D, 3.0D, 12.0D), box(4.0D, 0.0D, 0.0D, 12.0D, 3.0D, 16.0D), box(2.0D, 0.0D, 2.0D, 14.0D, 3.0D, 14.0D), INSIDE), IBooleanFunction.ONLY_FIRST); public AlchemicalCauldronBlock() { super(Properties.of(Material.METAL).sound(SoundType.METAL).harvestLevel(3).strength(2F,2F)); // this.registerDefaultState(this.stateDefinition.any().setValue(LEVEL, 0)); // this.registerDefaultState(this.stateDefinition.any().setValue(LEVEL, Integer.valueOf(0))); } ... When I try to run this with either of the two attempts at registerDefaultState uncommented, I get this error: https://pastebin.com/vPf3UryC. For convenience, I believe this part is most relevant: How can I avoid this? My registry classes look like this, if it helps: public class registry { public static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, AlchemyPlus.MODID); public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, AlchemyPlus.MODID); public static void register() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); BLOCKS.register(modEventBus); ITEMS.register(modEventBus); registerItems.register(); registerBlocks.register(); } } public class registerBlocks { public static final RegistryObject<Block> ALCHEMICAL_CAULDRON = register("alchemical_cauldron", AlchemicalCauldronBlock::new); static void register() {} private static <T extends Block> RegistryObject<T> registerNoItem(String name, Supplier<T> block) { return registry.BLOCKS.register(name, block); } private static <T extends Block> RegistryObject<T> register(String name, Supplier<T> block) { RegistryObject<T> ret = registerNoItem(name, block); registry.ITEMS.register(name, () -> new BlockItem(ret.get(), new Item.Properties().tab(ItemGroup.TAB_BREWING))); return ret; } } Full GitHub repository available here.   (Other minor problem(?):  I copied the methods getShape and getInteractionShape from net.minecraft.block.CauldronBlock and I'm getting these weird warnings. What's up with that? Do I need to worry about it?)  
    • Personally I use IForgeRegistryEntry#getRegistryName and then ResourceLocation#getNameSpace to get the id of the object.
    • you can get a block form a ResourceLocation, take a look at NBTUtil#readBlockState, do somthing like that
    • I am running forge version 1.16.5 36.1.31 on a server with a lot of mods and when a player refreshes the server list, it sends a long error in the server console. Additionally, the server list displays "Can't connect to server", despite refreshing and actually being able to connect to the server. here's the links to the logs: https://gist.github.com/WaffleTraits/83885b1539d5711fabff73a91924e665 https://gist.github.com/WaffleTraits/5ae78e6eaa330422bbc9f7226faf60ce Here's what's displayed in console when a player refreshes server listing: https://hastebin.com/ativexeyoy.properties server is running on ubuntu 20.04 and is using java 8 for this forge instance.
