Cooldown

It's java so it's the same as bukkit, you just need to change around some things.

 

The following should work:

Code (Text):

//Creating variable
boolean isOnCooldown;


//setting variable in your commands method on true and ask // if isOnCooldown is false your command should work


new BukkitRunnable() {
  int cooldown = <seconds>;

  public void run() {
    if(cooldown <= 0) {
      isOnCooldown = false;
      cancel;
    }

    cooldown--;
  }

}.runTaskAsyncronously(<Your Instance Method>, <Time in seconds> * 20);
