Help with playerMoveEvent

Hi im having problems with checking if a hashmap contains the location of the block when the player passes over. i got it to work when i haden't got the if(Hashmap.containsKey(loc)){
but i need that one
this is my code.

Code:

    @EventHandler(priority = EventPriority.NORMAL)
    public void onPlayerMoveEvent(PlayerMoveEvent event)
        {
        Player player = event.getPlayer();
    Location loc = player.getLocation();
    loc.setY(loc.getY() -2);
    if (plugin.Mine.containsKey(loc)){
   
      player.sendmessage("you just passed over the block");
 
                           
                            plugin.Mine.remove(loc);               
               
                }
                       
   
               
        }}

Any help would be much appruciated.

 

its not recomment to use locations as key in a hashmap, if the player is standigng on 0.164 then it wont trigger an block on 0.1639, I recommend converting it to an vector, because vectors are just x y z as an int, and then comparing it

 

Ok i'l try that

 

Or use the block location.... player.getLocation().getBlockX() and y and z
