Im trying to add an option to enable a 3 seconds delay everytime i pause the game, i first tried to make the option without any other functionality but i couldn't do anything. im new to this coding language

import funkin.modding.module.Module;
import Std;
import funkin.ui.options.OptionsState;
import funkin.ui.options.PageName;
import flixel.util.FlxSave;
import flixel.FlxG;
import funkin.play.PlayState;
import funkin.util.Constants;

class DelayedPauseModule extends Module
{
    var save = Null;

    var pause:Bool = true;

    function bindSave(){
        save = new FlxSave();    
        save.bind("delayedpauseoptions", "Pause3S");
    }

    function closeSave(){
        if(save != null)save.close();
        save = null;
    }

    function new(){
        super("Delayed Pause", 1);
        bindSave();

        if(save.data.pause == null)
            save.data.pause = true;

        pause = save.data.pause;

        closeSave();
    }

    var inOptions:Bool = false;

    override function onStateChangeEnd(event){
        super.onStateChangeEnd(event);
        inOptions = false;
        if(Std.isOfType(event.targetState, OptionsState)){
            var prefs = event.targetState.pages.get(PageName.Preferences);
            inOptions = true;

            bindSave();

            prefs.createPrefItemCheckbox("Delayed Pause", "", function(value) {
                save.data.enabled = value;
                enabled = value;

            }, save.data.pause);
            
        }else if(inOptions)
            closeSave();
    }
}

Few things:

1. you should always include what problem you're actually having, is it a compile error, a runtime error, or just unexpected behavior? if any of these, you need to either tell us the error, or the unexpected behavior and the your desired behavior
2. Most of this code has nothing to do with Flixel, it mainly seems like it uses funkin mod code. so you would probably find better help by asking other funkin modders

I'll try asking funkin modders, Thank you for the asnwer
