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

[Tatuck]

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.

More instructions

I wrote this in 1.15.2. The angle is given in radians. In any case you should test this solution whether or not it creates some errors in some special cases.

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.

Thank you guys! You saved me!
