Ragdoll activation problem

DMS

Hello all! What problem I'm facing is currently trying to change the character's state to kinematic to rigid by having the threshold of the health to 0 or lower than. I tried doing signals to work it hasn't, I tried using the other solution in a different discussion though that doesn't work. I'm still clueless of what's wrong

extends Spatial
var Enemy_HP = 100
var trigger
onready var hint = $"3D hint"
onready var anim = $"AP".get_animation("Test")
#onready var target = $"../3D hint"
onready var Tar = $"Player"
onready var rag = [get_node("Head"),get_node("ArmR"),get_node("ArmL"),get_node("Chest"),get_node("LegR"),get_node("LegL")]
signal hit
func _ready():
	_ragdoll()
	
	anim.set_loop(true)
	$"AP".play("Test")
	

func _damage():
	Enemy_HP -= 10
	print(Enemy_HP)
	pass
func _ragdoll():
	if Enemy_HP <=0:
		for rigid_body in rag:
			rigid_body.mode = RigidBody.MODE_RIGID
			return true
	else:
		for rigid_body in rag:
			rigid_body.mode = RigidBody.MODE_KINEMATIC
			rigid_body.add_to_group("enemy")
func _physics_process(delta):
	_ragdoll()
	if _ragdoll() == true:
		_ragdoll()
		$"AP".stop(true)
		pass

I may have solve my problem hold up.

Turns out I can just state a condition in one my functions to trigger a ragdoll instead of having to check it every frame in the physics or process (Although the physics one doesn't seem to work for me)

func _damage():
	Enemy_HP -= 10
	print(Enemy_HP)
	if Enemy_HP <=0:
		_ragdoll()
	pass
func _ragdoll():
	$"AP".stop(true)
	for rigid_body in rag:
		rigid_body.mode = RigidBody.MODE_RIGID
