I cannot track players health to trigger cinematic sequence device can anyone debug my code

using { /Fortnite.com/Devices }
using { /Fortnite.com/Characters }
using { /Fortnite.com/Playspaces }
using { /Verse.org/Simulation }
using { /Verse.org/Verse }

hello_world_device := class(creative_device):

@editable
MyDevice : cinematic_sequence_device = cinematic_sequence_device {}


# Runs when the device is started in a running game
OnBegin<override>()<suspends>:void= 
    AllPlayers: []player = Self.GetPlayspace().GetPlayers()
    if (FirstPlayer : player = AllPlayers[0]):
        if (FortniteCharacter : fort_character = FirstPlayer.GetFortCharacter[]):
            health:=FortniteCharacter.GetHealth()
            maxhealth:=FortniteCharacter.GetMaxHealth()
            loop:
                Sleep(0.0)
                if ( health=250.0):
                    MyDevice.Play()
                    break

I’m still working on It here is the new code It’s working now but got a new issue it’s only applying for one player I need to know how to fix that ):

using { /Fortnite.com/Devices }
using { /Fortnite.com/Characters }
using { /Fortnite.com/Playspaces }
using { /Verse.org/Simulation }
using { /Verse.org/Verse }
using { /Fortnite.com/Game }

hello_world_device := class(creative_device):

@editable
MyDevice : cinematic_sequence_device = cinematic_sequence_device {}


# Runs when the device is started in a running game
OnBegin<override>()<suspends>:void= 
    AllPlayers: []player = Self.GetPlayspace().GetPlayers()
    if (FirstPlayer : player = AllPlayers[0]):
        Print("First step")
        if (FortniteCharacter : fort_character = FirstPlayer.GetFortCharacter[]):
            Print("2nd step")
            maxhealth:=FortniteCharacter.GetMaxHealth()
            
            loop:
                Sleep(0.0)
                Print("Checking health")
               health:= FortniteCharacter.GetHealth()
                if (health<250.0):
                    Print("Myuasfh")
                    MyDevice.Play()
                    break
