* Notes
- we need a collisionshape to tell the physics engine the boundaries of this plane
- add a child node CollisionShape2D to the CharacterBody2D root node of this scene
- in the Inspector, click on Shape to determine what type of shape we are using

** create script for falling
- hit the 'attach new or existing script' button on the upper right corner of the scene dialog
- make sure that the script:
  - inherits from CharacterBody2D
  - the Template is 'Node Default'
  - Built in Script is OFF

*** script functions
- ready() starts when node is set
- process() is called every time a frame is called
- NOTE: better to use physics_process because that's what the engine is going to use
  - so change process to physics process
     #+BEGIN_SRC gdscript
     _physics_process(delta: float) ->void:
     #+END_SRC

** CharacterBody2D
*** properties
**** velocity
- has an 'x' and a 'y'

**** up_direction
- tells physics engine how to know if we are on a floor or not
- can tell us if we are on a ceiling or a wall
