I used to _draw()Path2D and the control points in 2D games like:

func _draw():
    draw_polyline($Path.curve.get_baked_points(), Color.red, 2, true)
    for p in $Path.curve.get_point_count():
        draw_circle($Path.curve.get_point_position(p), 8, Color.red)
    update()

Obviously, it doesn’t work in 3D games. What is the equivalent of that in 3D?

In other words, I want the Path curve and control points to be visible in Play Mode. How can that be achieved?

Thank you for your time!

You can use ImmediateGeometry node to draw something from code.
See https://docs.godotengine.org/en/stable/classes/class_immediategeometry.html
Also, you can take a look at GitHub - dbp8890/line-renderer: A GDScript implementation of a line renderer in Godot.
