[Tutorial/Beginner] Making configs

damn this java

hmm ok... i probably just shut up as I do it differently... with a seperate class and getters and setters..

totally agree with you after reading my post again... quick and dirty most of the times only means dirty...

 

Orebfuscator seems to do the same thing, a seperate class with getters and setters. I think I can grok this method:

https://github.com/lishd/Orebfuscat...id/orebfuscator/utils/OrebfuscatorConfig.java

 

First of all this is a very well-structured and easy to understand How to about configurations.

I don't know if my question can be placed in here but I am somehow not able to even start a configuration file variable.
I am using netbeans (version 7.2 on mac osx lion) for my plugin creation (I am a newbie in Java development, but already wrote 3 plugins for a server of my friend (and aren't a newbie in general programming)).
I used Dinnerbones videos to learn plugin programming, thats also the reason why i used netbeans (and not eclipse).
But it seems to be like the netbeans depencies are too old: Bukkit still has the old Configuration code in it (I cant import the org.bukkit.configuration.* classes). And I don't know how to update the depencies.
I already tried to use the newest bukkit.jar as a library but failed (The menu option was not there because it's based on a Maven-Project :/ ).

Was the "Logger log = Logger.getLogger("Minecraft");" code also implemented in the new version? I am still using "System.out" for cmd line prints.

My question now is: does anybody knows if i made anything wrong in Netbeans (any solution for how to solve my bukkit version error) or just use Eclipse for the future ?

Any help is appreaciated and thanks in advance!
- and sorry for my english, its not my first language

 

I've always had trouble updating Bukkit and Craftbukkit through Maven and eGit in Eclipse as well, I just delete the projects and start over every time there's a major enough shift that I need to update it.

 

I already tried that in Netbeans but hadnt changed anything (maybe its caching the downloaded files?), seems to be like i have to use eclipse now (I also had trouble with netbeans in the past).

Thanks for the quick reply!

Edit: Seems to work now like a charm with eclipse!

 

Do it work in 1.1?

 

I see no reason why configs shouldn't work. They have worked for me so far. The only thing that wont work is my example because they are now outdated. But i will change them at a later date

 

Code:

        List<String> messages = plugin.getConfig().getList(" motd.list ");
        for (String s : messages) {
            event.getPlayer().sendMessage(s);
        }

Eclipse hates this ... it suggests that messages be cast to an object. That won't work, though, as sendMessages needs it as a String. Any suggestions?

 

Try replacing
List<String>
to
String[]

 

Nope; it still thinks List<object> is the answer.

I wish there was somewhere to cast it.

 

Right, List<String> is the answer. Can you show me how you defined the string array / list, and also how you've done it in the config.

Make sure it is the same concept as the /rules example.

 

I did it the same as the rules example;

Code:

    @EventHandler(priority = EventPriority.LOW)
    public void onPlayerJoin(final PlayerJoinEvent event) {
        List<String> messages = plugin.getConfig().getList("motd.list");
        for (String s : messages) {
            event.getPlayer().sendMessage(s);
        }
    }

 

Code:

    @EventHandler(priority = EventPriority.LOW)
    public void onPlayerJoin(final PlayerJoinEvent event) {
        List<Object> messages = plugin.getConfig().getList("motd.list");
        for (Object s : messages) {
            event.getPlayer().sendMessage((String) s);
        }
    }

Code:

String[] messages = { "derp", "herp", "merk" };

Code:

config.addDefault("motd.list", Arrays.asList(messages));

 

Thank you, you're a beautiful human being!

 

Is there a way to check if a config file already exists? I dont want to overwrite the current configuration file. Or does Bukkit automatically check this?

 

If it exists i'm pretty sure it wont overwrite.

 

In case of you can do : getStringList("motd.list");

You have here all the method that you can use on a ConfigurationSection : http://jd.bukkit.org/doxygen/d9/dfb...1_1configuration_1_1ConfigurationSection.html

(and YamlConfiguration is implementing that interface)

 

Hi

I am pretty sure I have followed everything your tutorial says to do, and it compiles properly, and it also makes the config file, but whenever I try calling values from it, I get this error:

 

Can you show me your code, and specify which line is line 40? You have a NPE is all. Maybe you misspelt a config paths name, or using the wrong type of value.

 

I ended up rerwiting my code so that I don't need a config file, but line 40 was the code where I was calling the value from the config file. It went like

player.setHealth(config.getInt("starve"));

I don't know what the problem is, unless it has to do with the fact that the config.getInt("starve"); in a separate method, but I am not sure.

Edit: That was probably it, but I don't need it anymore, so thanks!

Double Edit: I was trying to call the variables from an onCommand method, and I was wondering how you do that

 

To get your config from inside a command method depends. If your command is in your main class then you can use
this.getConfig()
if its a separate class, you make a constructor in that class pointing to your main class, and use
plugin.getConfig()

 

thanks!

 

I am trying to add an item to the list but keep getting an error no mater what I do. can someone give me a simple answer on how to add to the list in the config because I have to add a players name to the list.

 

config.getList("path").add(player.getName());
saveConfig();

if that doesnt work, i will take a better look later

 

My friend helped me with it and it was a little different then that

Code:

List<Object> list = getConfig().getList("Members");
list.add(plr.getName());
saveConfig();

 

Hi, when I try to use plugin.config.getInt, Eclipse gives an error and says "JavaPlugin.config is not visible". I've looked through this thread, but none of the other solutions really help me..

 

maybe it's private? make it public if you want to make it accessable in outside methor or make a getter method.

 

Use
plugin.getConfig().getInt

 

Hi I have a problem: I use command executors to handle my commands, but I get errors when I try to get an int from the config file. I'll post the error log and the code.

From the first post:

I still can't manage to get any values from my config while in another class. So that I can compare and see what I'm missing, could I see a short example of a technically complete Main class and Listener class that pulls a config value in the listener?
