[1.7.2] Show nametags only if looking to player

[Hunterz]

Hi,I would like show nametag only if looking to player. Trying this code, but, when point to player, i see nametags on all players.

 

 

 

@SubscribeEvent
@SideOnly(value = Side.CLIENT)
public void onRenderLiving(RenderLivingEvent.Specials.Pre event){
   	
    	if ((event.entity instanceof EntityPlayer))
        {
          if (event.isCancelable())
          {
          	Minecraft mc = Minecraft.getMinecraft();
        	MovingObjectPosition objectMouseOver = mc.objectMouseOver;
        	// makes a variable for where you look
        	if(mc.objectMouseOver != null && mc.objectMouseOver.entityHit != null) {
  
              event.setCanceled(false);
        	}
        	else {
        	  event.setCanceled(true);
          	}
          }
        }
}

 

 

 

Is possible cancel event only for selected player?
