Its good that you are eager to crack this problem. Though I think you shouldn't be sticking to this problem for too long, since the ConfigOptions do work, and are primarily not ment to be changed ingame. I would recommend finnishing up the rest of the mod, and go back to this problem afterwards.

 

Anyway, on to the new problem. are all the customClassMethod Called when they should? (e.g. ConfigHandler - init()method., ModConfiguration - getCategory() method. )

Honestly I dont know if thats is the problem. It wouldnt make sence that your config would be completly empty. I think there should be at least the 'vanilla' configCatagories if it would work this way. Therefore, make sure (with call hiearchy for example) if the methods get called correctly. Otherwise I dont think it will work.

 

Or lex must know what went wrong.

My last guese would be, that the init() method in the ConfigHandler Class doesnt get called, otherwise I dont know it anymore. Im sorry.

 

Edit: I would recommend sticking with the forge system for now, and try again later. The only problem is order/ranking, and its not gamebreaking either, fortunatly. So I would focus on (possible)bigger problems.

Welp, thanks for trying to help guys. I'll just delete with having the configuration being in a weird order

Your config is empty because, your private Map<String, Property> properties = new TreeMap<String, Property>(); that is defined in new class is empty... :D (because fields can't be overrided like methods)...

You have 3 options to avoid this:

- Override all emthods and fields in order to fill your porperties and not super one

- Use reflection to get private field

- getValues(), returns this private list without sorting. All you want to do now is convert Map<String, Property> into List<Property>...

Oops, forgot to post my code

 */
public ModConfiguration(File file) {
	super(file);
}

@Override

	ModConfigCategory ret = categories.get(category);

	if (ret == null) {

In this case, you have to reflect a private field, it s done like so:

1) Get class (by name or in any way).

2) Call class.getDeclaredField(name) method to get private field (getField does not return private fields, but return super defined fields (getDeclaredField does not)).

3) Call field.setAcessible(true), this will make this field value acessible.

4) Now call either:

4.1) get(instance), where instance is instance of object from which you want to get this field (can be null for static fields)...

4.2) set(instance, value), where instance is instance of object from which you want to get this field (can be null for static fields) and value - value you want to set it to...

I'm a little confued at step 4, do I get the Configuration class name? I'm using the Reflection class I made like this

 

ModConfiguration

package common.zeroquest.core.configuration;

import java.io.File;
import java.lang.reflect.Field;
import java.util.Map;
import java.util.TreeMap;

import common.zeroquest.reflection.ReflectionConfig;

import net.minecraftforge.common.config.Configuration;

public class ModConfiguration extends Configuration {

public ModConfiguration() {}

/**
 * Create a configuration file for the file given in parameter.
 */
public ModConfiguration(File file) {
	super(file);
}

@Override
public ModConfigCategory getCategory(String category) {
	ModConfigCategory ret = ReflectionConfig.main(Configuration.class.toString()).get(category);

	if (ret == null) {
		if (category.contains(CATEGORY_SPLITTER)) {
			String[] hierarchy = category.split("\\" + CATEGORY_SPLITTER);
			ModConfigCategory parent = categories.get(hierarchy[0]);

			if (parent == null) {
				parent = new ModConfigCategory(hierarchy[0]);
				categories.put(parent.getQualifiedName(), parent);
				changed = true;
			}
			for (int i = 1; i < hierarchy.length; i++) {
				String name = ModConfigCategory.getQualifiedName(hierarchy[i], parent);
				ModConfigCategory child = categories.get(name);

				if (child == null) {
					child = new ModConfigCategory(hierarchy[i], parent);
					categories.put(name, child);
					changed = true;
				}

				ret = child;
				parent = child;
			}
		}
		else {
			ret = new ModConfigCategory(category);
			categories.put(category, ret);
			changed = true;
		}
	}
	return ret;
}
}

 

Reflection

package common.zeroquest.reflection;

import java.lang.reflect.Field;
import java.lang.reflect.Method;

public class ReflectionConfig {

public static void main(String[] args) {
	try{
		Class c = Class.forName("net.minecraftforge.common.config.Configuration");
		//Method methodList[] = c.getDeclaredMethods();
		Field field = c.getDeclaredField("categories");
		field.setAccessible(true);
		field.get(args);
		System.out.println(field);
	}catch (Exception e){
		System.out.println("ERROR:" + e.getMessage());
	}
}
}

field.get(instance) is the equal to instance.fieldName, with one but: You can access private fields like that...

 

Some examples of reflection.

These will be true:

1) 

this.a == getClass().getField("a").get(this);

if a is public field

2) 

this.a == getClass().getDeclaredField("a").get(this);

if a is not super field

If 

a

is private super field (

SuperClass{private Object a; ChildClass extends SuperClass{}

) , 1ststatement will give compile error, 2nd will throw null pinter, 3rd will throw null pinter, 4th will work:

1) 

Object b = a;

2) 

Object b = getClass().getField("a").get(this);

3) 

Object b = Class.forName("SuperClass").getField("a").get(this);

4) 

Object b = Class.forName("SuperClass").getDeclaredField("a").get(this);

 

 

So it total, your method should probably look like this:

Get super map with reflection

Do all stuff and thigs with this map that you just got (get values, add, remove...)

Set set super map using reflection to this changed map (just to be sure it changed)

Return needed value

I'm still confused. How am I suppose to call if I'm using a separate class with the reflection methods inside?
