Create Small delay

This may seem like a pretty basic question but I need an efficient way to create a delay. I am attempting to create my version of TNT Run, however when I use,

Code:

            if(this.joined.contains(p) && (p.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.TNT)){
                    p.getLocation().getBlock().getRelative(BlockFace.DOWN).setType(Material.AIR);

the TNT deletes out from under the player to quickly. I tried using thread.sleep like so,

Code:

            if(this.joined.contains(p) && (p.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.TNT)){
                try{

                    Thread.sleep(10);
                }catch(Exception s)
                {
                    System.out.println("Exception caught");
                }
                    p.getLocation().getBlock().getRelative(BlockFace.DOWN).setType(Material.AIR);
                }

however, this caused lots of server lag when multiple people played. Any other ways I can create a small delay between getting the players location and removing the block from under them?

Like this?

Code:

new BukkitRunnable() {
    @Override
    public void run() {
        //code here
    }
}.runTaskLater(Plugin, <delay in ticks>);

 

Is Plugin a variable for something?

Well I am assuming Plugin would just be "this"

Yeah, that would be correct.

 

Like this?

Code:

        if (gamestarted = true){
            if(this.joined.contains(p) && (p.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.TNT)){
                new BukkitRunnable() {
                    @Override
                    public void run() {
                        p.getLocation().getBlock().getRelative(BlockFace.DOWN).setType(Material.AIR);
                    }
                }.runTaskLater(this, 20);
                }

            }

 

Yeah, it should work.

 

@Official_Spendrew It depends what 'this' represents. If you are doing this in your 'main' class then it would work.

 

Got it to work
Thanks for your suggestions. Here is my final code.

Code:

if (this.joined.contains(p) && (p.getLocation().getBlock().getRelative(BlockFace.DOWN).getType() == Material.TNT)) {
                final Location plocation = p.getLocation();
                new Timer().schedule(new TimerTask() {
                    @Override
                    public void run() {
                        plocation.getBlock().getRelative(BlockFace.DOWN).setType(Material.AIR);
                    }
                }, 150);

Nice! And in case you didn't know, you should always avoid using Thread.sleep inside plugins because it would make the main thread sleep and basically cause a lot of lag. I'm not really able to explain this properly, but it's definitely something you should refrain from doing!
