Loading a list from a config.

So, the title makes it sound pretty easy, and I hope it is, as I am okay with feeling like a derp today.

So, what I am trying to do is load a list from an unknown name.

Like this:

PHP:

test:
  winBlock:
    World: world
    X: 128
    Y: 80
    Z: 272
  spawn:
    World: world
    X: 135
    Y: 68
    Z: 263
  lobby:
    World: world
    X: 134
    Y: 82
    Z: 281
  sign3:
    World: world
    X: 121
    Y: 69
    Z: 268
  sign2:
    World: world
    X: 121
    Y: 69
    Z: 269
  sign1:
    World: world
    X: 121
    Y: 69
    Z: 270


In this case, I do not know test, let me throw in another example.

PHP:

test:
  winBlock:
    World: world
    X: 128
    Y: 80
    Z: 272
  spawn:
    World: world
    X: 135
    Y: 68
    Z: 263
  lobby:
    World: world
    X: 134
    Y: 82
    Z: 281
  sign3:
    World: world
    X: 121
    Y: 69
    Z: 268
  sign2:
    World: world
    X: 121
    Y: 69
    Z: 269
  sign1:
    World: world
    X: 121
    Y: 69
    Z: 270
blah:
  winBlock:
    World: world
    X: 128
    Y: 80
    Z: 272
  spawn:
    World: world
    X: 135
    Y: 68
    Z: 263
  lobby:
    World: world
    X: 134
    Y: 82
    Z: 281
  sign3:
    World: world
    X: 121
    Y: 69
    Z: 268
  sign2:
    World: world
    X: 121
    Y: 69
    Z: 269
  sign1:
    World: world
    X: 121
    Y: 69
    Z: 270


In this last case, I do not know test or blah, how would I get them?

I have tried:

Code:java

        for (String s : arenaConfig.getStringList("")){
            KOTL.log.severe(KOTL.tag + "after for s in getStringList -D-");
 
            HashMap<String, Location> blah = new HashMap<String, Location>();
            KOTL.log.severe(KOTL.tag + s);
            for (String s2 : arenaConfig.getStringList(s)){
                KOTL.log.severe(KOTL.tag + s2);
                String wName = arenaConfig.getString(s + "." + s2 + ".World");
                double x = arenaConfig.getDouble(s + "." + s2 + ".X");
                double y = arenaConfig.getDouble(s + "." + s2 + ".Y");
                double z = arenaConfig.getDouble(s + "." + s2 + ".Z");
                Location one = new Location(KOTL.plugin.getServer().getWorld(wName), x, y, z);
                blah.put(s2, one);
            }

In my mind that should have worked properly, but there was no output, I did not get to any of my debug line at all.

Any help that you could give me would be greatly appreciated.

Thanks in advance,
LegoPal92.

 

I'd like to know also.. *follows*

You may be interested in the getConfig.getKeys(true); method. As explained here, it returns the key, and their children's keys recursively.

 

Thanks, I'll try that.
EDIT: Thanks, GusGold it worked!

Now, on to the next problem.

I am trying to save an arena to MySQL, the syntax is fine, but the Location is null.

Here is the method that I am using.

Code:java

 
 
 
public static void loadArenas(){
        KOTL.log.severe(KOTL.tag + "after loadArenas -D-");
        HashMap<String, HashMap<String, Location>> arenaParts = getLocations();
        for (String s : arenaParts.keySet()){
            KOTL.log.severe(KOTL.tag + s);
 
            Location winBlock = null;
            Location spawn = null;
            Location lobby = null;
            Location sign1 = null;
            Location sign2 = null;
            Location sign3 = null;
            HashMap<String, Location> locations = arenaParts.get(s);
            for (String s2 : locations.keySet()){
                if (s2.equalsIgnoreCase("winBlock")){
                    winBlock = locations.get(s2);
                } else if (s2.equalsIgnoreCase("spawn")){
                    spawn = locations.get(s2);
                } else if (s2.equalsIgnoreCase("lobby")){
                    lobby = locations.get(s2);
                } else if (s2.equalsIgnoreCase("sign1")){
                    sign1 = locations.get(s2);
                } else if (s2.equalsIgnoreCase("sign2")){
                    sign2 = locations.get(s2);
                } else if (s2.equalsIgnoreCase("sign3")){
                    sign3 = locations.get(s2);
                }
            }
 
            Arena a = new Arena(spawn, winBlock, lobby, sign1, sign2, sign3, s);
            KOTL.log.severe(KOTL.tag + a.getMapName() + " has been loaded.");
            LoadArenas.saveArena(a);
        }

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

 

LegoPal92 Where is your locations map?

 

Oh that, the getLocations() line?

Just a sec.

Code:java

public static HashMap<String, HashMap<String, Location>> getLocations(){
        HashMap<String, HashMap<String, Location>> toBeReturned = new HashMap<String, HashMap<String, Location>>();
        KOTL.log.severe(KOTL.tag + "after getLocations -D-");
        for (String s : arenaConfig.getKeys(false)){
            KOTL.log.severe(KOTL.tag + "after for s in getStringList -D-");
 
            HashMap<String, Location> blah = new HashMap<String, Location>();
            KOTL.log.severe(KOTL.tag + s);
            for (String s2 : arenaConfig.getStringList(s)){
                KOTL.log.severe(KOTL.tag + s2);
                String wName = arenaConfig.getString(s + "." + s2 + ".World");
                double x = arenaConfig.getDouble(s + "." + s2 + ".X");
                double y = arenaConfig.getDouble(s + "." + s2 + ".Y");
                double z = arenaConfig.getDouble(s + "." + s2 + ".Z");
                Location one = new Location(KOTL.plugin.getServer().getWorld(wName), x, y, z);
                blah.put(s2, one);
            }
 
            toBeReturned.put(s, blah);
        }
        return toBeReturned;
    }

 

LegoPal92
You might want to check that arenaParts.get(s); isn't returning null, and the same with locations.get(s2); Do a

Code:java

if (something == null)
   getLogger().severe("NULL!!!!!");

 

I just did, and it turns out that it is not null. Any more suggestions?

 

LegoPal92
So locations.get(winBlock) != null?

 

I guess I misunderstood what you were asking. I tested if arenaParts.get(s) was null.

That locations.get("winBlock") is null. Maybe I cannot store a HashMap inside of a HashMap. If not, what would you suggest me to use?

 

LegoPal92
Alright, so I reckon that this bit is your problem (line inside your getLocation() function):

Code:java

KOTL.plugin.getServer().getWorld(wName)

If the server can't find a world by that name, it will return null, so make sure

Code:java

arenaConfig.getString(s + "." + s2 + ".World");

is returning the name of a currently loaded world.

 

GusGold Is the world loaded when plugins are enabling? because if not, that would be the cause, the world that I am testing, and that it is retrieving in is the main world.

 

LegoPal92
So long as you haven't added something like "load: STARTUP" to your plugin.yml, your plugin will load after the world has. the issue may be capitalization or you have set a different world in your server.properties file?

 

I have not added that in my plugin.yml, The capitalization is the same, I know for certain because the way I am saving it is using Location.getWorld.getName(); The world is the same as the one in the server.properties as well.

 

LegoPal92
I have had troubles with getting the world object from a string before. A sure-fire way would be to

Code:java

World worldIWant = null;
List<World> worlds = getServer.getWorlds();
for (World world : worlds){
    if (world.getName().equalsIgnoreCase(arenaConfig.getString(s + "." + s2 + ".World")){
        worldIWant = world;
        break;
    }
}

This loops through all loaded worlds and sees if any equal your worlds' string name

 

Thanks for all your help, I have realized that my error was that this is not a String List, and that what I should do is hard code the getting the Spawn, winBlock, etc. If I run in to problems later on, I will tahg you again, if that's alright.

 

GusGold Random question:

When ever I try to set a list as an ArrayList(Im pretty sure it takes a ArrayList) it turns out as:
{}

Any examples as using a list?

 

JPG2000 Nothing like threadjacking, but anyway :3
Do you mean like

Code:java

List<String> list = new ArrayList<String>();

?

 

GusGold Yeah.

I know java, I know how to make an ArrayList. Just when ever I either set or get (specificly set) it just sets it as {}.

Example:

Code:java

Config config; //Pretend this is set up
 
ArrayList<String> list = new ArrayList<String>();
list.add("hello");
 
public void set() {
config.set("flower", list);
}

It would turn out as:
flower: {}


EDIT:
I'll try it again. Also, if I would wanto get all the values like so:

Code:

world:
- mario
- sethbling
- yoga
- soup

Would I do so like this:

Code:java

for (String s: config.getList("mario")) {
//S would be 'mario' 'sethbling' yadayada
//Code
}

 

JPG2000
Try getConfig().getStringList("path.to.string.list");

 

GusGold I men't getStringList, I was thinking out of my head, and I didn't look through the method list. I tried it again, and it worked. Seemed as my list was null ;(

Anyways, does the list always return a string?

 

JPG2000 Yes, but you can do stuff like Integer.parseInt("123"); and Boolean.parseBoolean("false");
