I've been looking for a solution to make Path2D visible and controllable in game mode for ages. Even though I found a bit of info here and there, they were not complete and flawless. So I decided to make one for my game that actually works.

Godot community has always been extremely friendly and helpful to me to find solutions to various problems. Now is my turn to contribute back to community.

If you are looking for a way to make Path2D visible and controllable in play mode, here is the code to attach to the root node (replace the number of hyphens with the same number of tabs):

`onready var path = get_node("Path2D")`

`var idx = 0`

`var c = Color.red`

`func _input(event):`

-`if event is InputEventScreenTouch:`

`#SELECT POINTS`

--`for p in path.curve.get_point_count():`

---`if path.curve.get_point_position(p).distance_to(event.position) < 40:`

----`idx = p`

----`update()`

`#SELECT HANDLES`

---`var a = path.curve.get_point_position(p) - path.curve.get_point_out(p)`

---`var b = path.curve.get_point_position(p) - path.curve.get_point_in(p)`

---`if a.distance_to(event.position) < 40:`

----`idx = p`

---`if b.distance_to(event.position) < 40:`

----`idx = p`

-`if event is InputEventScreenDrag:`

`#DRAG POINTS`

--`for p in path.curve.get_point_count():`

---`if path.curve.get_point_position(p).distance_to(event.position) < 40 :`

----`path.curve.set_point_position(idx, path.curve.get_point_position(idx) + event.relative)`

----`update()`

`#DRAG HANDLES`

---`var a = path.curve.get_point_position(p) - path.curve.get_point_out(p)`

---`var b = path.curve.get_point_position(p) - path.curve.get_point_in(p)`

---`var d = path.curve.get_point_position(p) - event.position`

---`if a.distance_to(event.position) < 40:`

----`path.curve.set_point_in(idx, -d + event.relative)`

----`path.curve.set_point_out(idx, d + event.relative)`

----`update()`

---`if b.distance_to(event.position) < 40:`

----`path.curve.set_point_out(idx, -d + event.relative)`

----`path.curve.set_point_in(idx, d + event.relative)`

----`update()`

`#DRAW`

`func _draw():`

-`draw_polyline(path.curve.get_baked_points(), c, 1, true)`

-`for p in path.curve.get_point_count():`

--`if p != 0 and p != path.curve.get_point_count() - 1:`

---`draw_circle(path.curve.get_point_position(p), 8, c)`

---`draw_circle(path.curve.get_point_position(p) - path.curve.get_point_in(p) * -1, 5, c)`

---`draw_circle(path.curve.get_point_position(p) - path.curve.get_point_out(p) * -1, 5, c)`

---`var a = path.curve.get_point_position(p) - path.curve.get_point_in(p) * -1`

---`var b = path.curve.get_point_position(p) - path.curve.get_point_out(p) * -1`

---`var cp = path.curve.get_point_position(p)`

---`draw_polyline(PoolVector2Array([a, cp]), c, 1, true)`

---`draw_polyline(PoolVector2Array([b, cp]), c, 1, true)`

-`update()`
