Config Doesnt Update the File or the actual variable


Recommended Posts


I have made a config using the annotation.  It displays fine but the values dont seem to actually save nor do they change.  Here is my config class:


package net.drok.poverhaul;

import net.minecraftforge.common.config.Config;

@Config(modid = POHMod.MODID)
public class ModConfig {

	public static Tools tools = new Tools();
	public static class Tools
		@Config.Comment("Defines whether or not to use a more realistic harvest system.")
		public boolean fixedHarvest = true;
		@Config.Comment("The speed scaling of tools with a quality of 0")
		public double minToolScaling = 0.3;
		@Config.Comment("The speed scaling of tools with a quality of 100")
		public double maxToolScaling = 1.2;


And I am using ModConfig.tools.value to access the values.  As i said i can change them in the gui but the value is always the default value when i print it to the console.

I don't know much about configs, but I believe you need to synchronize your config with ConfigManager#sync().
At least, if you're talking about GUI changes, this is definitely the case. Read below:


Where would i call the sync function?  Is there an event?

I will make it simple.
To save changes made from GUI, subscribe to ConfigChangedEvent.OnConfigChangedEvent. Check if event's modid is the modid of your mod, then call ConfigManager#sync(). I don't have access to sources right now, but the code looks like this:

public class ConfigEventHandler {
/* I prefer to make it inner class of my config class,
   but it doesn't have to be, it just needs to be registered.
   Read docs about events if you don't understand. */
  public static void onConfigChanged(ConfigChangedEvent.OnConfigChangedEvent event) {
    if (event.getModid().equals(modid) {
      ConfigManager.sync(modid, Config.Type.INSTANCE);


I believe,ConfigManager#sync() also saves changes made to fields to your config file, but as I said, I don't know much about configs .
