Solved Delay between actions

Hi there everyone
I am new to the plugin so I don't know how can I make a countdown between commands and commands : (
Can anyone give me some advice or make me a sample to see? : )
I want to add a 1-second countdown between the two potion effect
What should I do : )

Code:

    @EventHandler
    public void onBowShot(EntityShootBowEvent e) {

        Player player = (Player) e.getEntity();

        if (e.getEntity() instanceof Player && e.getProjectile() instanceof Arrow) {
            player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 6));
            player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 6));
        }
    }

 

@timtower
Am I doing right on the BukkitRunable?
I'm sorry to disturb you : (
But I need your help very much : )
And thank you for your generous help anyway

Code:

    @EventHandler
    public void onBowShot(EntityShootBowEvent e) {

        Player player = (Player) e.getEntity();
      
        if (e.getEntity() instanceof Player && e.getProjectile() instanceof Arrow) {
            player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 6));
            new BukkitRunnable(){
                @Override
                public void run() {
                    player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 254));
                    this.cancel();
                }
            }.runTaskTimer(this,20L);

        }
    }

 

@timtower
so doing like this will be fine ?
But why when I shoot an arrow and there is nothing happened? : )
Maybe some of my commands are wrong?

Code:

    @EventHandler
    public void onBowShot(EntityShootBowEvent e) {

        Player player = (Player) e.getEntity();

        if (e.getEntity() instanceof Player && e.getProjectile() instanceof Arrow) {
            player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 6));
            new BukkitRunnable(){
                @Override
                public void run() {
                    player.addPotionEffect(new PotionEffect(PotionEffectType.LEVITATION, 20, 254));
                }
            }.runTaskLater(this,20L);

        }
    }

 

@timtower
Yes, But just when I shoot an arrow out
It supposed I have LEVITATION effects
However I don't get any of these
Maybe some of my commands are wrong? :thinking:

 

@timtower
I have register the event inside the plugin.yml file already by the following codes

Code:

name: JumpShoot
main: com.blackhat.jumpshoot.main
version: 1.0
description: jump and shoot
author: BlackHat707

But how can I know if the event gets called? : )

@timtower
onEnbale:

Code:

@Override
    public void onEnable() {
        getLogger().info("Hello World!");
    }

[23:24:17 INFO]: [JumpShoot] Enabling JumpShoot v1.0
[23:24:17 INFO]: [JumpShoot] Hello World!

 

@loman Is the method inside the main class, or is it in another class?

 

I just open 1 class : )
so it should be in the main one

 

@loman Okay, i just wanted to make sure because the BukkitRunnable requires the main class instance.

Did you register the listener as @timtower told you? If so, did you get it working or do you still have issues?

 

Oh! @KarimAKL @timtower
Thank you for your help
I finally succeed : )
