How to get an Int from a config

Hey guys,
I am trying to get an int from a config. This is what I am trying to work with.

The int definition

Code:java

int level = getConfig().getInt("Knockback");

The int invocation

Code:java

featherswag.addUnsafeEnchantment(Enchantment.KNOCKBACK, level);

Stacktrace

I think this may be a problem with the way I define my ints.

I am not using any string builders, as I am not sure how we could use it for an int, if it is possible, please link me to any type of resource that could help me out.

Can you post your config file?

 

Zettelkasten Sure.

Code:

Name:God Fern
#Name of your item
 
Lore:test lore
#Lore of the item
 
Knockback: 25
#Knockback level
 
Item:17
#Item ID

 

Hey there, could you please post the entire class? I think I may know what the issue is :3

 

Did you make
<yml>.setInt("Path", 5);
or
<yml>.set("Path", 5);
or
<yml>.setString("Path", 5);
i woud recommend <yml>.setInt("Path", 5);

 

you need a space.
so...
Name:God Fern
Lore:test lore
Item:17
becomes
Name: "God Fern"
Lore: "TextLore"
Item: 17

This here,shows that you received the error while drawing a String, not an int, I believe.

 

MrAwellstein Thanks! That fixed some of the problems. But not the name and lore part
Glass

 

What other problems? Btw, if you want you can add me on Skype, and I can help you when ever I'm on.
SkypeID: Mr.Awellstein

 

MrAwellstein Ok cool! And the problem is getting the name and the lore.

 

Can you provide a stack trace?

Wrong. YamlConfiguration.loadConfiguration(File) will first read the file, dump that all into a String, and internally call that method ;3.
Glass_Eater84 you are still experiencing the same error. Post the full YAML file you are using.

 

fireblast709

Code:

Name: God Fern
#Name of your item
 
Lore: test lore
#Lore of the item
 
Knockback: 25
#Knockback level
 
Item: 17
#Item ID

 

Glass_Eater84 Make sure the jar you use is updated (latest version) and restart the server.

 

fireblast709 Yes I know but I am not getting the name from the config nor the lore. I am getting the ID and the knockback level

 

Glass_Eater84 what code do you use to get the name and lore? Also if you seriously get a stacktrace, I'm wondering why you get anything at all.

 

fireblast709

This is how I create the Strings

Code:java

 String name;
String lore1;

This is how I define them

Code:java

 this.name = getConfig().getString("Name");
this.lore1 = getConfig().getString("Lore");

and this is how I invoke them.

Code:java

temStack featherswag = new ItemStack(Material.getMaterial(getConfig().getInt("Item")), 1);
ItemMeta fs = featherswag.getItemMeta();
featherswag.addUnsafeEnchantment(Enchantment.KNOCKBACK, level);
ArrayList<String> lore = new ArrayList<String>();
lore.add(lore1);
fs.setDisplayName(name);

What I really need to get fixed for the time being is the strings not being casted onto the ItemMeta.

 

fs.setItemMeta(fs.getItemMeta()) ?

 

Glass_Eater84 call featherswag.setItemMeta(fs);

 

PandazNWafflez Didn't work, took away the enchant from the config :/

 

Glass_Eater84 get the ItemMeta after you set the enchantment.

 

fireblast709 Worked thanks! OFF TOPIC: How would I do two commands in one class? I tried this but it failed to work.

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
{
  if (cmd.getName().equalsIgnoreCase("feather")) {
    if (sender.hasPermission("feather.use")) {
      sender.sendMessage(featherswag);
      Player player = (Player)sender;
      ItemStack featherswag = new ItemStack(Material.*****, 1);
      featherswag.addUnsafeEnchantment(Enchantment.******, level);
      player.getInventory().addItem(new ItemStack[] { featherswag });
      player.updateInventory();
      return false;
  }
  return false;
}
 
        @SuppressWarnings("deprecation")
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
{
  if (cmd.getName().equalsIgnoreCase("fire")) {
    if (sender.hasPermission("*****")) {
      sender.sendMessage(featherswag);
      Player player = (Player)sender;
      ItemStack featherswag1 = new ItemStack(Material.******, 1);
      featherswag1.addUnsafeEnchantment(Enchantment.******, 2);
      player.getInventory().addItem(new ItemStack[] { featherswag1 });
      return false;
    }

 

Glass_Eater84 you just use the same method but after your if statement checking if the command name is feather, you put else if command name is fire.

 

Glass_Eater84 use one onCommand method. Then, check if(feather)...else if(fire)

 

fireblast709 Can you show me an example, please. I have also tried this:

Code:java

public boolean onCommand2(CommandSender sender, Command cmd, String label, String[] args)
{

But that didn't work.

 

Example;

Code:java

public blablabla onCommand(parameters here){
  if(label.equalsIgnoreCase("command1"){
 
  }else
    if(label.equalsIgnoreCase("command2"){
        sender.sendMessage("command lala");
    }
 
}

Made without editor.

 

Glass_Eater84 I gave you a pretty descriptive description in my last post. Use one onCommand method, and check the cmd.getName() in there.

McMhz thanks for the spoonfeed :/. No, that was not a compliment before you got that idea.

 

fireblast709 McMhz Thanks! I did it, and got it working what I did was;

Code:java

 else if (cmd.getName().equalsIgnoreCase("fire")) {
    if (sender.hasPermission("fire.use")) {
      sender.sendMessage(fire);
      Player player = (Player)sender;
      ItemStack featherswag1 = new ItemStack(Material.***, 1);
      featherswag1.addUnsafeEnchantment(Enchantment.*****, 2);
      featherswag1.addUnsafeEnchantment(Enchantment.*****, level);
      player.getInventory().addItem(new ItemStack[] { featherswag1 });
      player.updateInventory();
      return false;

 

By the way, In future plugins, I recommend using lower-case paths in the config
For example instead of using
Knockback: 25

VVV In the config, you should use this instead because configs are case-sensitive.
knockback: 25

But yeah, you don't have to do that, but It's recommended.
//Edit: If yo do that you have to update the getConfig().getString() thingies too.
But since your "paths" are just one word in this plugin, you don't have to do it.
