Solved Setting timer that triggers stuff after countdown.

I need to start a timer FROM the seconds that the player gives. "/timer start 10" would result in a 10 second delay before executing a message.

I know that 20L is 1 second, so to get the correct countdown time you would do:

Code:

final int Countdown = Integer.parseInt(args[1]) * 20;
 
Countdown + L

I think...

Adding L to the end of a literal number (e.g. 20L) makes it a long rather than an int. The only way to do this with a variable is to cast it:

Code:

(long)Countdown

This is technically not the same because the first one doesn't do any casting and is just different at compile time, but you don't need to concern yourself with that if you don't want to.

If you were asking how to actually do the countdown, then here's the code:

Code:java

 
new BukkitRunnable() {
    //Code
 
}.runTaskLater(plugin, 20L);
 

 

It works, thanks

Also how would I make count down the final 5 seconds?

Make a self canceling task.

Code:java

 
// MyPlugin.java
 
public class MyPlugin extends JavaPlugin {
    public void onEnable() {
        int startCount = 10; // get this from the user input "/timer start 10" or whatever
 
        BukkitTask task = new Countdown(this, startCount).runTaskTimer(this, 0, 20); // "this" is a reference to MyPlugin, in case you want to use this in a different class
    }
 
    public void onDisable() {
        //
    }
}
 

Code:java

 
//Countdown.java
 
public class Countdown extends BukkitRunnable {
    private final MyPlugin plugin;
    private int counter;
 
    public Countdown(MyPlugin plugin, int counter) {
        this.plugin = plugin;
        if (counter < 1) {
            throw new illegalArgumentException("counter must be greater than 1");
        } else {
            this.counter = counter;
        }
    }
 
    public void run() {
        if (counter > 0) { 
            plugin.getServer().broadcastMessage("Commence greeting in " + counter--);
        } else {
            plugin.getServer().broadcastMessage("Welcome to Bukkit! Remember to read the documentation!")
            this.cancel();
        }
    }
}
