Error With My Reading of Config.Yml

Hello Everyone! I have a ok knowledge of java programming for bukkit, but every time i try and receive an integer or string from a config.yml file that i generated, i can never get it to work, any ideas on what im doing wrong?

 

Hello pdkkid188,
there could be a may possible reasons, but it would be easier for us if you could post some code.
And did you try take a look at the Bukkit Configuration Tutorial?

 

sure

Startup

Code:

    public void onEnable() {
        try {
            Metrics metrics = new Metrics(this);
            metrics.start();
        } catch (IOException e) {
            // Failed to submit the stats :-(
        }
        PluginManager pm = this.getServer().getPluginManager();
        pm.registerEvents(this.bl, this);
        pm.addPermission(new Permissions().canExplode);
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() + " Version " + pdfFile.getVersion() + " Has Been Enabled. Created By Pdkkid");
        this.getServer().getConsoleSender().sendMessage(ChatColor.RED  + "Need To Advertise Your Server?" + ChatColor.GOLD + " Http://MajorMcServers.Net");
        getConfig().options().copyDefaults(true);
        saveConfig();
    }

Code Trying To Grab From Config

Code:

    if (e.getEntity() instanceof Player){
        World deathWorld = player.getWorld();
        Location playerspot = player.getLocation();
            if(player.hasPermission(new Permissions().canExplode)) {
                deathWorld.createExplosion(playerspot.getX(), playerspot.getY(), playerspot.getZ(), plugin.getConfig().getInt("ExplosionPower"), false, false);
            }
        }
    }   
}

Config

Code:

# Default Configuration file.
# Explosion Power is the power when a player dies, and he creates an explosion
ExplosionPower: 3

 

and what exactly is the problem with your code?
is it throwing exceptions or what is it doing?

edit:
try replace "getConfig().options().copyDefaults(true);"
with "saveDefaultConfig();"
that usually work's for me

 

in game when i die, it should take the value in the config, which is set to 3 and create and explosion where the player was standing, but instead, i receive this error on death

Edit:
when i remove the plugin.getConfig().getInt("ExplodePower") and replace it with 3, which is the value in the config.yml it works perfectly

 

make sure that "plugin" is not null and "ExplodePower" exists in your config

 

Code:

public static DeathExplode plugin;

Code:

# Default Configuration file.
# Explosion Power is the power when a player dies, and he creates an explosion
ExplosionPower: 3

 

then don't forget to call "plugin = this;" in your onEnable method

 

Still getting that error:/

this is the line of code which is trying to grab from the config

Code:

deathWorld.createExplosion(playerspot.getX(), playerspot.getY(), playerspot.getZ(), plugin.getConfig().getInt("ExplosionPower"), false, false);

Edit:
This is the part of the line, that should work, but gives me huge error codes when i die in game
plugin.getConfig().getInt("ExplosionPower")

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

 

remove the caps in your getInt and your config, i think that will fix it but I am really unsure, i remember before i came across a similar problem and I asked a friend and that is what I believe he said.

 

wait i think i know what im doing wrong and its not my grabbing from the config, that works fine, but how would i change an integer value into a float value?

 

put the integer name and put F at the end of it

 

what do you mean by that? Im trying to take getConfig().getInt("power") and turn it from an integer to a float, so i could just define it as

Code:

Int power = getConfig().getInt("power");

Where would i put an F in that?

 

Oh, i got the wrong idea, you would just need to cast it to a float

 

): im still getting an error, am i doing anything wrong?

Code:

deathWorld.createExplosion(playerspot.getX(), playerspot.getY(), playerspot.getZ(), (float) plugin.getConfig().getInt("power"), false, false);
