Hi guys, how are you?

Im working on a Flappy Bird clone and I have a problem. When the bird flap I want it to rotate instantly to a 30 degree angle. It does but it last only a fraction of a second and then comes back to its previous angle. How can I archive that? Here is my code

extends RigidBody2D

func _physics_process(delta):
  if Input.is_action_just_pressed("ui_jump"):
    _flap()

  if (linear_velocity.y > 0):
    _rotate()

func _flap():
  set_angular_velocity(0)
  set_rotation(deg2rad(-30))
  set_linear_velocity(Vector2(linear_velocity.x, -200))

func _rotate():
  set_angular_velocity(3)

See, the physics engine gets fussy if you directly mess with the RigidBody2D in the wrong way.

Look into the _integrate_forces(state) method that RigidBody2D has.
