    I want to hook up making a delay for players to use this mining tool I made with my explosive server (to delay or keep down griefing) and I just cannot figure it out. There is no code left of the delay but I know I need a hashmap to store the players and that is about it. here is the code important code for my sulphur that you need to see:
    Code:java
    1. @EventHandler
    2. public void onBlockInteract(PlayerInteractEvent e) {
    3.     Block b = e.getClickedBlock();
    4.     Action act = e.getAction();
    5.     Player p = e.getPlayer();
    6.     Material hand = p.getItemInHand().getType();
    7.     World w = p.getWorld();
    8.  
    9.     if (enabled) {
    10.         if (hand.equals(Material.SULPHUR)) {
    11.             if (act.equals(Action.RIGHT_CLICK_BLOCK)) {
    12.                 if (b != null) {
    13.                     Block bTarget = p.getTargetBlock(null, 5);
    14.                     Block bAbove = bTarget.getRelative(BlockFace.UP);
    15.                     Block bNorth = bTarget.getRelative(BlockFace.NORTH);
    16.                     Block bSouth = bTarget.getRelative(BlockFace.SOUTH);
    17.                     Block bEast = bTarget.getRelative(BlockFace.EAST);
    18.                     Block bWest = bTarget.getRelative(BlockFace.WEST);
    19.                     Block bDown = bTarget.getRelative(BlockFace.DOWN);
    20.  
    21.                     Block bSEast = bTarget.getRelative(BlockFace.SOUTH_EAST);
    22.                     Block bSWest = bTarget.getRelative(BlockFace.SOUTH_WEST);
    23.                     Block bNEast = bTarget.getRelative(BlockFace.NORTH_EAST);
    24.                     Block bNWest = bTarget.getRelative(BlockFace.NORTH_WEST);
    25.  
    26.                     Block bUpNorth = bTarget.getRelative(0, 1, 1);

    I've been using the same thing over and over and it is really making me fed up, as I have just tried two methods, and one didn't work at all (using scheduleSyncDelayedTask) and the other was in which I used a video tutorial and it used the Thread.sleep method which I don't find comfortable using.

    Here is a good class you could use in the resource section for starting to use cooldowns.

    I've ran into doing this type of thing a lot of times and I keep getting errors or problems. Here is my current code:

    88. }


    My stack trace for "Plugin cannot be null" when it is not, and it says I get two errors, one at line 434:
    Code:
    task = Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(p, new BukkitRunnable() {
    and I get another error at 226:
    Code:
    d.startCooldown(p, map);
