Solved [HELP] Event Listener with configuration file

Hello, I've started making plugins and it is really cool , but I can't get out how I can use informations stored in a config.yml in a EventListener. Can please someone help me?

I have this code:

Code:

public class PlayerListener implements Listener{
   
    public static ItemEffects plugin;
   
    @EventHandler
    public void PlayerInteract(PlayerInteractEvent event){
        Player player = event.getPlayer();
        ItemStack item = new ItemStack(Material.getMaterial(plugin.getConfig().getInt("effects.speed.item", 353)));
        int duration = plugin.getConfig().getInt("effects.speed.duration", 200);
       
        if(player.getInventory().getItemInHand().equals(item)){
            if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK){
                player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, duration, 2));
            }
        }       
    }
}

What I'm trying to do is getting the item and it's duration out from the config.yml and use them in the code. When I don't try to get the integers from the config.yml it works, just when i try to get it from there it won't work.

Does someone have a solution?

Thanks in advance, Lionhard98

 

the listener is a different class. this is a java thing here is what you have to do:

Create a constructor for the class:

Code:

public class PlayerListener implements Listener{
 
    public static ItemEffects plugin;
 
    PlayerListener(int d){
 
    }
 
    @EventHandler
 
    public void PlayerInteract(PlayerInteractEvent event){
 
        Player player = event.getPlayer();
 
        ItemStack item = new
 
    ItemStack(Material.getMaterial(plugin.getConfig().getInt("effects.speed.item",
 
    353)));
 
        int duration = plugin.getConfig().getInt("effects.speed.duration", 200);
 
        if(player.getInventory().getItemInHand().equals(item)){
 
            if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==
 
        Action.RIGHT_CLICK_BLOCK){
 
                player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED,
 
        duration, 2));
 
            }
 
        }
 
    }
 
}

Create a field in the class:

Code:

public class PlayerListener implements Listener{
 
    int duration;
 
    public static ItemEffects plugin;
 
    PlayerListener(int d){
 
    }
 
    @EventHandler
 
    public void PlayerInteract(PlayerInteractEvent event){
 
        Player player = event.getPlayer();
 
        ItemStack item = new
 
    ItemStack(Material.getMaterial(plugin.getConfig().getInt("effects.speed.item",
 
    353)));
 
        int duration = plugin.getConfig().getInt("effects.speed.duration", 200);
 
        if(player.getInventory().getItemInHand().equals(item)){
 
            if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==
 
        Action.RIGHT_CLICK_BLOCK){
 
                player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED,
 
        duration, 2));
 
            }
 
        }
 
    }
 
}

Assign the passed in variable to field:

Code:

public class PlayerListener implements Listener{
 
    int duration;
 
    public static ItemEffects plugin;
 
    PlayerListener(int d){
 
    duration = d;
 
    }
 
    @EventHandler
 
    public void PlayerInteract(PlayerInteractEvent event){
 
        Player player = event.getPlayer();
 
        ItemStack item = new
 
    ItemStack(Material.getMaterial(plugin.getConfig().getInt("effects.speed.item",
 
    353)));
 
        int duration = plugin.getConfig().getInt("effects.speed.duration", 200);
 
        if(player.getInventory().getItemInHand().equals(item)){
 
            if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() ==
 
        Action.RIGHT_CLICK_BLOCK){
 
                player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED,
 
        duration, 2));
 
            }
 
        }
 
    }
 
}
 

Pass in the variable:

find this line:

Code:

getServer().getPluginManager().registerEvents(new
PlayerListener(), Plugin);

and add this to it:

Code:

getServer().getPluginManager().registerEvents(new PlayerListener(getConfig().getInt("effects.speed.duration", 200)), Plugin);

then you should be able to use the "duration variable any where you want.
if this makes no sense to you look up a tutorial about passing Java classes variables

 

First of all, thank you for your answer, I'm going to try it out in a few minutes. Thank you very much. I'll tell if it worked.

Somehow it doesn't work. :/ But I'll try to find a tutorial about passing java classes variables.

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

 

Can it be that you missunderstood me? After this, I can use the integer "duration" from the PlayerListener class in other classes, right? I need that I can use duration and itemID from ANOTHER class IN the PlayerListener class. Sorry, I didn't explain it right.

EDIT: Please can you give me another instruction, please? I looked already at several tutorials of passing variables into other classes, but that a) Didnt work, b) I didnt understand it. :/

Thanks in advance, Lionhard98

 

qhenckel Yes! I just tried it again and it works perfectly. I don't know how I can thank you.
A for you.
