- CharacterBody2D as root node
- change the node name to "Plane" (unnecessary but why not)

** character body 2D plane node
- Sprite to animate the 3 frames
- CollisionShape2D for physics
- AnimationPlayer to animate the rotation of the plane
- EngineSound (audio? node?)

** animated sprite 2D
- add it
- rename it to Sprite

*** create a sprite frames resource
- go to Inspector->AnimatedSprite2D->Animation

  #+attr_html: :width 600px
  file:../../_share/media/img/section04/lesson04/EX04c.png

** resources
- currently the sprite we created is embedded as an internal resource to our plane scene
- if you save it, then the information regarding the frames will be moved to that tres file you saved
  - allows you to reuse the frame resource

*** saving the sprite frame as a resource
- click on Inspector->AnimatedSprite2D->Animation->Sprite Frame drop down arrow
- in the pop up menu click on 'save as'
