Verse Beginner, Need Help with Simple Problem

This’ll probably be light work for those of you guys with pretty much any experience with verse, but I’m still learning so I’m struggling with this.

I’m trying to make a player that falls under a certain class (and triggers a switch to be on) to be eligible for the ability to crouch to double their health. Uncrouching returns it back to default.

I got this to work without the switch logic, but I don’t want every player in the lobby to have this feature. How do I add an if statement that checks for the switch to be on and subscribes the crouch ability to the instigating player?

HealthCrouch := class(creative_device):

    #wip, broken - currently no check for switch device, idk how to program this
    
    @editable
    Switch : switch_device = switch_device{}

    CrouchEvent(FortniteCharacter : fort_character, IsCrouched : logic) : void=
        if (IsCrouched?): 
            #crouch adds double health
            FortniteCharacter.SetMaxHealth(160.0)
            FortniteCharacter.SetMaxShield(200.0)
        else:
            #uncrouch removes double health
            FortniteCharacter.SetMaxHealth(80.0)
            FortniteCharacter.SetMaxShield(100.0)

    #pretty sure this is unused
    SpawnEvent( Agent : agent) : void =
        if (FortCharacter := Agent.GetFortCharacter[]):
            FortCharacter.CrouchedEvent().Subscribe(CrouchEvent)

    OnBegin<override>()<suspends>:void=
        for (Player : GetPlayspace().GetPlayers(), FortCharacter := Player.GetFortCharacter[], Agent := agent):
            Sleep(1.0)
            #i need an if statement that subscribes to CrouchEvent if the switch is toggled on but i'm still struggling to implement
            #if (Switch := Switch.IfOnWhenCheckedEvent(FortCharacter)):
                #FortCharacter.CrouchedEvent().Subscribe(CrouchEvent)
