Can't load my configuration file

syntaxjedi · July 24, 2014

First post so excuse me if i don't include everything needed, but I find myself having a lot of trouble loading my config file into minecraft. For some reason the config file is generated every time I delete it but when I go to my mod in minecraft the config button is greyed out. I'm working with 1.7.10, the error log says it can't initialize gui factory

I've included a picture in case I'm not making myself clear enough.

The Button is grayed out for me as well... It seems like it is a WIP or you have to implement it yourself.

The error itself seems to be coming from your config class. Check if your config file is actually doing something (Being generated / accepting values), try to print out your config values and change them to see if they are actually being read.

But just an error (especially this) isn't enough to help you. Any code would be great

syntaxjedi · July 24, 2014

I'm sort of following along with a tutorial and all my code matches that in the videos, the only difference is that in the videos the config button actually works. I don't know which config class has the error, since I have two, so I'll post them both

configuration handler

package com.syntaxjedi.betterRPG.handler;

import java.io.File;
import com.syntaxjedi.betterRPG.reference.Reference;
import cpw.mods.fml.client.event.ConfigChangedEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.common.config.Configuration;

public class ConfigurationHandler 
{	
public static Configuration configuration;
public static boolean testValue = false;

public static void init(File configFile)
{	
	//create the configuration object from the given configuration file
	if (configuration == null)
	{	
		configuration = new Configuration(configFile);
		loadConfiguration();
	}
}

public static void loadConfiguration()
{
	testValue = configuration.getBoolean("configValue", Configuration.CATEGORY_GENERAL, false, "This is just a test value");

	if (configuration.hasChanged())
	{
		configuration.save();
	}
}

@SubscribeEvent
public void onConfigurationChangedEvent(ConfigChangedEvent.OnConfigChangedEvent event)
{	
	if(event.modID.equalsIgnoreCase(Reference.MOD_ID))
	{
		loadConfiguration();			
	}
}
}

gui config

package com.syntaxjedi.betterRPG.client.gui;

import com.syntaxjedi.betterRPG.handler.ConfigurationHandler;
import com.syntaxjedi.betterRPG.reference.Reference;
import cpw.mods.fml.client.config.GuiConfig;
import net.minecraft.client.gui.GuiScreen;
import net.minecraftforge.common.config.ConfigElement;
import net.minecraftforge.common.config.Configuration;

public class BetterRPGguiConfig extends GuiConfig
{
public BetterRPGguiConfig(GuiScreen guiScreen)
{
	super (guiScreen,
			new ConfigElement(ConfigurationHandler.configuration.getCategory(Configuration.CATEGORY_GENERAL)).getChildElements(),
				Reference.MOD_ID,
				false,
				false,
				GuiConfig.getAbridgedConfigPath(ConfigurationHandler.configuration.toString()));
}
}

You have to actually load the Config file after creating it:

public static void loadConfiguration()
{
        configuration.load();
        ...

Busti · July 24, 2014

I didn't know about the functionality of the Config buttons because I concentrated on other things recently since ID's aren't a problem anymore

syntaxjedi · July 24, 2014

I tried loading the configuration in loadConfiguration(), which I'm sad I didn't do in the first place, but still nothing. I'm about ready to say it's just not gonna work and give up

Busti · July 24, 2014

Where are you getting your config file path from? I got mine from "event.getSuggestedConfigurationFile()" in the MOD class.

syntaxjedi · July 24, 2014

I have the same thing in my mod class. ConfigurationHandler.init(event.getSuggestedConfigurationFile());

brandon3055 · July 24, 2014

That is something you have to implement yourself. Here is a tutorial

http://minalien.com/minecraft-forge-feature-spotlight-config-guis/

syntaxjedi · July 24, 2014

I was using that site in tandem to the tutorial videos on youtube, and the way I'm implementing it isn't any different than on the site.

jabelar · July 25, 2014

I followed same tutorial and it works great for me.

You can see the config button is active, and below you can see that the config is actually editable if I click that button:

jabelar · July 25, 2014

Where's your GUI factory class? Can you show all your code related to configruation? You should have an annotation in your main class pointing to the GUI factory class as well. Also, you say you do it but don't show your proxy call to the init() where you pass the file location. Coding is all about the details so need to see all related code to help you.

{	
	return null;
}

{	
	return null;
}

}

gui config

				GuiConfig.getAbridgedConfigPath(ConfigurationHandler.configuration.toString()));
}
}

config handler

package com.syntaxjedi.betterRPG.handler;

public class ConfigurationHandler

public static boolean testValue = false;

public static void init(File configFile)
{	
	//create the configuration object from the given configuration file

public void onConfigurationChangedEvent(ConfigChangedEvent.OnConfigChangedEvent event)
{	
	if(event.modID.equalsIgnoreCase(Reference.MOD_ID))
	{

	}
}
}

main mod class

package com.syntaxjedi.betterRPG;

@Mod(modid = Reference.MOD_ID, name= Reference.MOD_NAME, version= Reference.VERSION, guiFactory = Reference.CONFIG_GUI_CLASS)
public class betterRPG 
{	

@Mod.Instance(Reference.MOD_ID)
public static betterRPG instance;

@SidedProxy(clientSide = Reference.CLIENT_PROXY_CLASS, serverSide = Reference.SERVER_PROXY_CLASS)
public static IProxy proxy;

@Mod.EventHandler
public void preInit(FMLPreInitializationEvent event)
{		
	ConfigurationHandler.init(event.getSuggestedConfigurationFile());
	FMLCommonHandler.instance().bus().register(new ConfigurationHandler());
}

@Mod.EventHandler
public void init(FMLInitializationEvent event)
{

}

@Mod.EventHandler
public void postInit(FMLPostInitializationEvent event)
{

}
}

also i get this message in the system output pane when i run the game and i don't know what exactly it's complaining about

Kwibble · July 25, 2014

From the looks of your error, you aren't implementing an interface, or not extending something.

That's all I got for a ClassCastException.

syntaxjedi · July 25, 2014

That was my general thinking but I couldn't for the life of me figure out what to do, and google wasn't much help either

**EDIT**

I FIXED IT!!!! it was such a dumb mistake in my reference file i had

CONFIG_GUI_CLASS = "com.syntaxjedi.betterRPG.client.gui.BetterRPGguiConfig";

instead of

CONFIG_GUI_CLASS = "com.syntaxjedi.betterRPG.client.gui.GuiFactory";
