    Please post your config file, it's most likely an error within that.

    Code:
    Config:
    Message:
        Firstpot:
            effect: JUMP
            time: 2400
            level: 1
    You're trying to access Config.Firstpot.X when you should be accessing Config.Message.Firstpot.X.

    I believe you've got confused because of the commented bit in your config.

    Okay found it. You misspelled this:

    Take a look at the double O!

    Edit:
    Path in config:
    Code:
    Config.Firstpot.effect
    Path in code:
    Code:

    Slikey

    Stacktrace again please?

    And place this in the Eventhandler please.
    Code:java
    1.  
    2. System.out.println(plugin);
    3. System.out.println(plugin.getConfig());
    4. System.out.println(plugin.getConfig().getInt("Config.Firstpot.level"));
    5.  


    And upload a new stacktrace

    amatokus No, they're all wrong. On lines 32 and 33, your code looks like this;
    Code:java
    1. Listener Events = new Events(null);
    2. new Events(this);

    I'm not sure what you really mean to accomplish, but you're doing it wrong nonetheless. Replace those lines with this;
    Code:java
    1. Listener Events = new Events(this);

    I'm pretty sure it was just something you missed.

    Yep. Then the plugin causes the NullPointer in the other lines..

    amatokus Please read yourself through the Java-Conventions. Always start variable-name with a lowercase letter!

    Still not working. I think it's the way I use the new

    PotionEffect(PotionEffectType.getByName(plugin.getConfig()

    It's the only thing that is on line 34... So I'm almost sure it's that but .. how could I do?

    Any Idea?

    Says that you give a String to the PotionEffectType.getByName(), but the String is null, which is validated inside the Method with Validate.notNull(). Ergo: The plugin.getConfig().getString("config.firstpot.effect") returns null.

    Ok I get it but I don't realy understand how I should get the potion name in the Config then...

    Or how do I give a value to the potion effect name?

    Oh.. You never set up an config file...

    Add this to your Main.onEnable()-Method.
    Code:java
    1. this.getConfig().addDefault("config.firstpot.effect", "JUMP");
    2. this.getConfig().addDefault("config.firstpot.time", 2400);
    3. this.getConfig().addDefault("config.firstpot.level", 1);
    4.  
    5. this.getConfig().addDefault("config.secondpot.effect", "SPEED");
    6. this.getConfig().addDefault("config.secondpot.time", 1200);
    7. this.getConfig().addDefault("config.secondpot.level", 2);
    8.  
    9. this.getConfig().options().copyDefaults(true);
    10. this.saveConfig();

    Slikey thx for the code! It's working great!


    So If the user sets config for example :

    config:
    firstpot:
    effect: DAMAGE_RESISTANCE
    ..........


    The effect will be Damage_Resistance or still JUMP?

    EDIT: I'm so idiot I.. I can test myself x)
    EDIT2:WORKING THX
