Section Creation

So I'm trying to create a list that looks like this:

homes:
hashmap key 1
hashmap key 2
hashmap key 3
hashmap key 3
hashmap key 3

This will be in a config file, but I went through a lot of the options for it and they all give NPE when trying to call/use it:

Code:java

 
FileConfiguration.createPath(HomesConfig, "homes");
   for (Entry<String, Location> e:homes.entrySet()) {
       HomesConfig.set("homes."+e.getKey(), e.getValue());
   }
 

 

You can't save locations like that since they are not serializable. You will have to write your own location class or save a String representation of a location so you can just create a new location with what you saved.

Other than that, I offered a piece of code in the Resources section that can save HashMaps to configuration files.

An example of your own location class would be like the following class:

This is what I got actually:

Code:java

 
public FileConfiguration getHomesConfig() {
if (HomesConfig == null) {
File CMBhomesFile = new File(getDataFolder(), "homes.csv");
Boolean cmb = this.getConfig().getBoolean("Commandbookhomes");
if(cmb) {
BufferedReader r = null;
try {
r = new BufferedReader(new FileReader(CMBhomesFile));
} catch (FileNotFoundException e1) {
logger.info("FileNotFoundExeption:");
logger.info(e1.toString());
e1.printStackTrace();
}
String q;
try {
while((q = r.readLine()) != null) {
String[] info = q.split(",");
Location l = new Location(null, 0, 0, 0, 0, 0);
 
l.setWorld(Bukkit.getWorld(info[1].replaceAll("\"", "").trim()));
l.setX(Double.parseDouble(info[3].replaceAll("\"", "").trim()));
l.setY(Double.parseDouble(info[4].replaceAll("\"", "").trim()));
l.setZ(Double.parseDouble(info[5].replaceAll("\"", "").trim()));
l.setYaw(Float.parseFloat(info[6].replaceAll("\"", "").trim()));
l.setPitch(Float.parseFloat(info[7].replaceAll("\"", "").trim()));
 
homes.put(info[0].replaceAll("\"", "").trim(), l);
//HomesConfig.set("homes", homes);
FileConfiguration.createPath(HomesConfig, "homes");
for (Entry<String, Location> e:homes.entrySet()) {
HomesConfig.set("homes."+e.getKey(), e.getValue());
}
}
} catch (NumberFormatException e) {
logger.info("NumberFormatException: ");
logger.info(e.toString());
e.printStackTrace();
} catch (IOException e) {
logger.info("IOException: ");
logger.info(e.toString());
e.printStackTrace();
}
}
reloadHomesConfig();
}
return HomesConfig;
}
 

So I have to create the Hashmapwriter like you and then call it?
