Hi,
How I can move a KinematicBody to a target using Navigation.get_simple_path function and GDScript in a 3D space?
Thanks in advanced.

Here is a 2D analog for what you're trying to accomplish:

onready var nav = $Navigation2D
var destination = null
var navigation_path = []

func _physics_process(delta: float) -> void:
    if destination:
        move_towards_position(destination, delta)
        # if we're close enough, call it good
        if self.position.distance_squared_to(destination) < 5:
            self.position = destination
            destination = null
    elif not navigation_path.empty():
        destination = navigation_path.pop_front()

func _input(event: InputEvent) -> void:
    var start_position = self.position
    var end_position = get_end_position(event)
    var path = Array(nav.get_simple_path(start_position, end_position))
    if path.empty():
        return
    else:
        var always_starting_position = path.pop_front()
        navigation_path = path

Obviously, you'll need to implement move_towards_position() and get_end_position(). Something to keep in mind: get_simple_path() wants and returns points in local coordinate space, if i recall correctly, moving in 3D generally wants points in global space.
