Solved Cooldown help

So i made a hashmap like this
public HashMap<UUID, Long> cooldowns = new HashMap<UUID, Long>();
and i put players in the map like this
cooldowns.put(p.getUniqueId(), System.currentTimeMillis());
and i have a variable that has the seconds that i want the cooldown to be like this
final int seconds = 60;

my question is how do i check if the cooldown is over and do i subtract any time?
ive looked at many many posts about these types of cooldowns and haven't gotten anywhere

 

Thought about a Bukkit.getScheduler.runSyncDelayedTask ()?

 

yeah ive thought about it, what would you say the differences are about both of them and their advantages and disadvantages?

Because a lot of the threads ive read use the System.currentTimeMillis() over a scheduler

Instead of storing the current time, store the number 60.

Code:

cooldowns.put(p.getUniqueId(), 60);

1. Create a BukkitRunnable that goes off every second
2. In that BukkitRunnable, you can use cooldowns.replace(p.getUniqueId(), cooldowns.get(p.getUniqueId()) - 1) to lower the seconds left in the cooldown by 1.
3. Then, you can check if the cooldown is equal to 0 by using:

Code:

  if(cooldowns.get(p.getUniqueId()) == 0){

// cooldown over

   }  

Here is some more information on Scheduler Programming:

I know how to use schedulers, i was just wondering about the currentTimeMillis, but i guess ill end up doing the runnable

 

@Blackwing_Forged
current time - player time >= 60L
Is this what you want?

Code:

if (System.currentTimeMillis() - HashMap#get(uuid) >= 60L)
    // do something

 

is that if the time is up?

 

@Blackwing_Forged
Yes

 

Alright thanks
