Thanks heaps - Fig

 

@Fig loadConfig0() doesn't exist.

 

@bwfcwalshy How do I make it exist...I've seen people use this method, do i need an external jar? 3 words isn't really helping...

 

You'd make the method yourself most likely, tailored to what you are trying to load. If you're loading the default config, then as long as you're saving a default config when you start the server with the plugin for the first time, or if it exists as config.yml, the server will automatically load it.

Something like this:
this.getConfig().addDefault("this.is.a.path", true);
this.getConfig().options().copyDefaults(true);
saveConfig();

The plugin would automatically load the config on enable. I haven't read through all of your code, however I'm suggesting something that might be what you want. If not, disregard this.
