How do I make a config?

[guid118]

Hey all, 

I've been trying to make a config file in which (of course) some data will be stored, but for some reason the server never creates a file. 

The mod I'm making is server side only and should save an integer per player. 

I have made a config class and an init with:

 

private ForgeConfigSpec.Builder builder = new ForgeConfigSpec.Builder();

private ForgeConfigSpec spec;

 

public CommonConfig() {

spec = builder.build();

} 

public init() {

builder.comment("time in seconds that a player gets per day").define("timeperday", 5400);

builder.pop();

} 

// init gets called everytime the server starts, does this mean the value will always be set to 5400?

No I know, I have a further setup that requires a player name (I should probably use UUID) and saves it under there. The problem is that there is no config being created at all.
