State Machine Issue

[novel shore]

Im trying to make a state machine for 3D player movement but for some reason it isnt working

extends State
class_name PlayerForward

@export var player : CharacterBody3D
@export var speed = 5

func Enter():
    print("Entering PlayerForward state.")

func Exit():
    print("Exiting PlayerForward state.")


func Physics_Update(delta: float):
    var velocity = player.velocity
    velocity.z += -speed
    print("Moving Forward")
    
    if Input.is_action_just_released("Forward"):
        Transitioned.emit(self,"Idle")
    player.move_and_slide()``` This is the script for the player's forward state

extends State
class_name PlayerIdle

@export var player : CharacterBody3D
@export var speed = 5

func Enter():
    print("Entering Idle state.")

func Exit():
    print("Exiting Idle state.")

func Update(delta: float):
    if Input.is_action_just_pressed("Forward"):
        Transitioned.emit(self,"Forward")
    if Input.is_action_just_pressed("Back"):
        Transitioned.emit(self,"Back")
    if Input.is_action_just_pressed("Left"):
        Transitioned.emit(self,"Left")
    if Input.is_action_just_pressed("Right"):
        Transitioned.emit(self,"Right")

func Physics_Update(delta: float):
    var velocity = player.velocity
    velocity.x = move_toward(velocity.x,0,speed)
    velocity.z = move_toward(velocity.z,0,speed)
    player.move_and_slide()
```and this is for the Idle state

it prints out the Enter, Exit, and Moving Forward texts, but the player doesnt change positions

You have to update the player.velocity property after you've calculated the velocity. So, before calling player.move_and_slide() add this line

player.velocity = velocity

Do this in both scripts.
