i want to start again from the top of my script when the timer runs out

Question

so when i start the code and the timer runs out it would start again from the top

Answer 1

I am not sure what you mean with "the top of my script", but you could try to connect the timeout signal of your timer to the function _ready(). Or for better code readability you connect the timeout signal to its own function and then call _ready()

func _on_Timer_timeout():
    _ready()
