Need help adding cooldown on a kit abbilitie

Hey guys,
I am trying to add a 3 second cooldown on my kit abbilitie, but i dont know how to add one.
Anyways heres the code: http://pastebin.com/R75vhP96
Thanks for the help in advance

 

HashMaps and System.currentTimeMillis

 

Nonliker1000 If you want to be able to display the amount of time left (like when he tries to ctivate his ability again) you'd have to go with Skionz way. If you don't need to display the cooldown, store the playername in an arraylist, start a delayed task at 60 ticks and remove them from the arraylist when the cooldown is over.

 

Create a arraylist, and check if they are in it when the event is fired, and if they are, it will tell them they are on cooldown.

Code:java

ArrayList<String> cooldown = new ArrayList<String>
 
@EventHandler
public void onTest(PlayerInteractEvent e){
final Player p = e.getPlayer();
//e.getAction crap here
 
if(cooldown.contains(p.getName()){
p.sendMessage("You are on cooldown!");
} else{
p.sendMessage("You used your ability!");
cooldown.add(p.getName());
Bukkit.getScheduler().runTaskLater(this, new Runnable() {
 
public void run(){
cooldown.remove(p.getName);
p.sendMessage("You are no longer on cooldown!");
}, 100); //This is 5 seconds.
 
}
}

Like this ^^
