Wait 60 Minutes for a task to be done.

I know how to sort of use the scheduler, but im not totally sure what I should do when I want a task to start in 60 minutes after I specify the timer to start. Then after the task is run, do NOT run the timer again.

 

Look into using a syncDelayedTask. The delay for it is in server ticks, and there are 20 ticks in a second. So you'd want to use 72000 as your delay for a 60 minute delay.

 

Ok great! Thanks for the help! Now how would I check the time remaining? I think i might know how, but how SHOULD I do it? Because I usually do WAY more than I need to.

Probably make another task that runs every 20 or so ticks, right?

Any suggestions?

Code:java

getServer().getScheduler().scheduleSyncDelayedTask(this, runnable, 20*60*60);

 

Already solved that, but I had another question. Thanks though.

you need to check the time left over?

Instead of checking how much time is left over, you should set a task to run every 20 ticks (second) that counts down seconds in its object, which should be stored in an int, or whichever of your choice. you can then read from there.

 

Example?
But then I need to check when it gets to 0. Another task?

 

Lemme give u an example of what CorrieKay is saying...

Code:java

 
public Map<Player, Integer> timeRemaining = new HashMap<Player, Integer>();
public Map<Player, Boolean> inDelay = new HashMap<Player, Boolean>();
 // set up the 2 hashmaps somewhere make SURE they are not null.
 public void RepeatingRun(final Player p){
 myPlugin.getServer().getScheduler().scheduleAsyncRepeatingTask(myPlugin, new Runnable() { 
 
 public void run() { 
 for (Player p : getServer().getOnlinePlayers()) { 
 if (!indelay.get(p)) continue;  
 int time = inDelay.get(p);  
 time -= 1; 
 inDelay.put(p,time); 
 System.out.println(""+time);  
 } 
 } 
 }, 20L, 200L); 
 }

 

Eww Eww Formatting. Anyway to fix that? Hit edit, Highlight all, then theres like a white eraser thingy

 

Okay, im gonna assume that you want to create a countdown timer of an hour.

you'd do this

Code:

public class CountdownTimer extends TimerTask(){
int secondsPassed =0;
public void run(){
secondsPassed++;
if(secondsPassed>=3600){
//code to execute if an hour has passed. Possibly to tell another function to remove the task from the scheduler?
}
}
public int secondsPassed(){
return secondsPassed;//lets you see the amount of time that has passed.
}
}

In the main class, or whatever class will handle the task, you'd do this.

Code:

int hourCountdownTask;
hourCountdownTask = scheduler.scheduleAsyncRepeatingTask(plugin, task, 0[aka start executing now], 20 [aka execute once per second]);
 
public void cancelCountdownTask(){
scheduler.cancelTask(hourCountdownTask);
}

 

Fixed format.. soz about that XD.

 

Error here...

Code:java

 
 hourCountdownTask = scheduler.scheduleAsyncRepeatingTask(plugin, new CountdownTimer(), 0, 20);
 

Code:

The method scheduleAsyncRepeatingTask(Plugin, Runnable, long, long) in the type BukkitScheduler is not applicable for the arguments (-Plugin Name Here-, CountdownTimer, int, int)

Oh, Its fine! but why hashmaps with a player??? There isnt a player... lol.

just in case you wanted to create a countdown for individual players, probably

Lemme see the CountdownTimer class you made

also, most of what i wrote up there is psuedo code, and is only designed to show you the core functionalities. I'd recomend making your own

Ahh I see.

Ok, here you go.

CountdownTimer Class (open) CountdownTimer Class (close)

Code:java

 
import java.util.TimerTask;
 
public class CountdownTimer extends TimerTask {
intsecondsPassed =0;
 
   public int secondsPassed(){
      returnsecondsPassed;
   }
   public void run(){
    secondsPassed++;
     if(secondsPassed>=3600){
      //code to execute if an hour has passed. Possibly to tell another function to remove the task from the scheduler?
     }
   }
 
 
 
}
 

 

oh lol . Then just use an int, I assumed u were having a player.

 

Ahh got it.

 

lolWAT. longs??

i just saw that, hold on... that makes NO SENSE D:

Lemme see the class file that the scheduler is in.

 

kk

Part1:

Code:java

 
public BlaBlaBla plugin;
int hourCountdownTask;
BukkitScheduler scheduler = this.getServer().getScheduler();
 

Part2

Code:java

 
public void onEnable() {
logger.info("BlaBla v1.0 Enabling");
SetupConfigFiles();
hourCountdownTask = scheduler.scheduleAsyncRepeatingTask(plugin, new CountdownTimer(), 0, 20);
 
}

Wait! Now its working! What the?!

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Few issues, line 3 doesnt have a space between int and the variable name, and "plugin" isnt a declared variable. replace that with "this"

other than that... Uh, well, theres nothing wrong with it. I just wrote it exactly like you did, and im not getting any errors.

I have no idea why its saying those numbers are ints, when they're longs...

Edit: YAY!

 

So now after this delay, I need another shorter delay to start. Same setup? Haha

 

dont forget to stop the task. remember that int we saved? hourCountDownTask?

scheduler.cancelTask(hourCountdownTask) when you hit one hour. Then, in the same function, you can create another. However, i suggest creating a constructor within the countdown timer class that holds an amount of time that you want to make it cancel.

so the task scheduling would look like this:

Code:

scheduler.scheduleAsyncepeatingTask(this, new CountdownTimer(int goes here), 0, 20);

 

Got it. Thank you so much.

 

no problem! glad to help out
