Configuration file help

mrkirby153 · August 7, 2012

Hi,

I need help using configuration files for my mod. I tried the wiki article and it wasn't very detailed. I am a kind of person who learns by example. The wiki article has no examples of the finished project. I hope someone can give me an example on how to do it. Also, I tried looking at some other mods and it was no help.

If someone could please help me out, I would appreciate it!

A finished project is not needed though, the configuration file is literally just a couple of lines to set up and use... What help are you needing?

If you really want a finished project then look at cpw's IronChests project on github.

Just check out how Universal Electricity does the getConfigID and how it sets up the config files. It's really easy to understand once you figure it out!

You tried to name a null object, you cannot do that. Your Items and Blocks must be instanced before you name them.

Also, the empty capsuel naming is broken and when i try to craft an empty capsuel, i get an exp capsuel.

updated code:

I need to save and load STRING parameter to/from configuration file, but can't do it.

I use code:

Reveal hidden contents

@PreInit
public void preInit(FMLPreInitializationEvent event) {
	String t = "test string";
	Configuration config = new Configuration(event.getSuggestedConfigurationFile());
	config.load();
	t = config.get("main", "texture", "bla bla text").toString();
	config.save();
}

My resulting "t" equals "net.minecraftforge.common.Property@1866d49" string.

why is it? and how to fix?

Instead of

t = config.get("main", "texture", "bla bla text").toString();

You have to use

t = config.get("main", "texture", "bla bla text").value;

Took me 2 minutes of searching in the code.
