Scoreboard timer, check who's in a team (scoreboard).

Hello everyone. I have another problem in my coding. I am trying to make a timer on a scoreboard. I have already made a Offline player called Timer. But I just don't know how to decrease a value of 1 per second.
Also I need to check in which team someone is. I have 2 teams, red and blue. I want this because then I can spawn them seperately.

Code:

Code:

Excuse me, but i don't see anything about a timer. Only a score that represents a timer.
But where is the countdown for it?

Maybe this:

Code:

public void setupScoreboard() {
            sBoard = Bukkit.getScoreboardManager().getNewScoreboard();
          
            red = sBoard.registerNewTeam("red");
            blue = sBoard.registerNewTeam("blue");
        
            red.setAllowFriendlyFire(false);
            blue.setAllowFriendlyFire(false);
        
            red.setCanSeeFriendlyInvisibles(true);
            blue.setCanSeeFriendlyInvisibles(true);
        
            red.setPrefix(ChatColor.RED + "");
            blue.setPrefix(ChatColor.BLUE + "");
        
        
            // Stats
            Objective stats = sBoard.registerNewObjective("stats", "playerKillCount");
            stats.setDisplaySlot(DisplaySlot.SIDEBAR);
            stats.setDisplayName("§4Statistics");
            stats.getScore(Bukkit.getOfflinePlayer("§6Time")).setScore(1200);
        
            Bukkit.getScheduler().scheduleAsyncRepeatingTask(this, new Runnable(){
                       public void run(){
                             int timer = stats.getScore(Bukkit.getOfflinePlayer("§6Time"));
                              stats.getScore(Bukkit.getOfflinePlayer("§6Time")).setScore(timer);
                             timer--;
                       }
           }, 0, 20);                     
        }

Play with the code, it would maybe work.

I hadn't added the timer yet, because I didn't know how to. But thanks, I'll play with it a little. But what do these numbers represent?

Edit- Can't I make a for loop? Then I check if the timer isn't 0, and if it isn't then it decreases 1. That process continues every 1 second. Would that be possible?

 

@tovd1234 Which numbers?

 

}, 0, 20); <-- These

But can't I make a for loop? Then I check if the timer isn't 0, and if it isn't then it decreases 1. That process continues every 1 second. Would that be possible? (I don't know how to set the 1 second delay)

 

@tovd1234 The first number represents the delay in ticks. and the second number represents the time that repeating, also in ticks. 20 ticks is 1 Second.

You can use a while loop, but a runnable is maybe better.

Code:

int timer = 60;

while(timer != 0) {
     timer--;
}

Note: 60 would be 59. Because in Java starts by 0.

Okay, but wouldnt that make it 0 seconds. Because there is no delay defined there


EDIT: And when I'm using the Runnable I get an error at int timer = stats.getScore(Bukkit.getOfflinePlayer("§6Time"));. The error is Type mismatch: cannot convert from Score to int.
But setScore only accepts integers so if I change the type of timer to Score I get an error at setScore

Code:

Objective stats = sBoard.registerNewObjective("stats", "playerKillCount");
            stats.setDisplaySlot(DisplaySlot.SIDEBAR);
            stats.setDisplayName("§4Statistics");
            stats.getScore(Bukkit.getOfflinePlayer("§6Time")).setScore(1200);
    
            Bukkit.getScheduler().scheduleAsyncRepeatingTask(this, new Runnable(){
                       public void run(){
                             int timer = stats.getScore(Bukkit.getOfflinePlayer("§6Time"));
                              stats.getScore(Bukkit.getOfflinePlayer("§6Time")).setScore(timer);
                             timer--;
                       }
           }, 0, 20);                 
        }

 

@tovd1234 That's the reason you must use a Runnable.

Code:

int id = Bukkit.getScheduler().scheduleAsyncDelayTask(this, new Runnable(){
    
    @Override
     public void run(){
           if(timer == 0){
               Bukkit.getScheduler().cancelTask(id);
               return;
           }

            timer--;
     }

}, 20);

- Create a int variable called timer. And define time you want.

 

@Experminator Please check the edit in my last post
And the scheduleAsyncDelayTask does not work Error: The method scheduleAsyncDelayTask(Main, new Runnable(){}, int) is undefined for the type BukkitScheduler. If I change it to scheduleAsyncRepeatingTask it will show up like scheduleAsyncRepeatingTask

 

@tovd1234 Play with it. You find the explanation about that.

 

@Experminator Ok thnx

@Experminator Okay, I have figured it out (I think). But the timer doesnt seem to work. Maybe because the scoreboard isn't updating but idk.

This is the code for the Runnable timer I use:

Code:

this.getServer().getScheduler().scheduleAsyncRepeatingTask(this, new Runnable() {

                        @Override
                        public void run() {
                            if (timer != 0) {
                                timer--;
                            } else {
                                Bukkit.broadcastMessage("§cThe game has stopped!");
                            }
                        }

                    }, 0L, 20L);
        }

Or the problem is that I have the order of them wrong. Order: TOP [int timer > scoreboard > command to activate the timer] BOTTOM

@tovd1234 If you want for personal help, you can private message me.
Then i can give a quike reply

 

ok
