[1.12] EntityPlayer#rayTrace never matching entities?

I have an event handler that I'm trying to use to automatically give the glowing effect to any mobs the player looks at while priming his bow. So I'm using this code (including all the debug output for now):

 

@SubscribeEvent
	public void onPlayerUsingBow(PlayerTickEvent ev) {
		if (ev.phase == TickEvent.Phase.END) {
			EntityPlayer player = ev.player;
			ItemStack usingItem = player.getActiveItemStack();
			int isInUse = player.getItemInUseCount();
			if (usingItem.getItem() instanceof ItemBow && isInUse > 0) {
				RayTraceResult trace = player.rayTrace(80.0d, 1.0f);
				System.out.println("Type: " + trace.typeOfHit);
				System.out.println("Entity: " + trace.entityHit);
				System.out.println("Is Living?: " + (trace.entityHit instanceof EntityLivingBase));
				if (trace.typeOfHit == RayTraceResult.Type.ENTITY && trace.entityHit != null
						&& trace.entityHit instanceof EntityLivingBase) {
					EntityLivingBase livingEnt = (EntityLivingBase) trace.entityHit;
					livingEnt.addPotionEffect(new PotionEffect(MobEffects.GLOWING, 20));
					System.out.println("Added glowing to " + livingEnt);
				}
			}
		}
	}

 

According to the debug output, though, the RayTraceResult's type is ALWAYS Block, even if I'm staring directly at a zombie or some such mob. Like, I can be just one block away, aiming directly at the zombie's head or body, and it still gives me a Block type result with a null entityHit.

Am I misunderstanding how to use the EntityPlayer#rayTrace method, or is there a better way to go about finding which mob the player is looking at (within 80 blocks or so)?

Whatever Minecraft needs, it is most likely not yet another tool tier.

You might actually want the function getMouseOver() in EntityRenderer, it's pretty much what you're looking for (note: this existing method is client-side only and if you need to run the code on the server, you will have to duplicate it).

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
