* Notes

** scenes
there are three basic scenes we are going to create

1. Gem Scene
   - Sprite2D
   - CollisionShape2D
2. Paddle Scene
   - Sprite2D
   - CollisionShape2D
3. Game Scene
   - Sprite2D
   - Paddle Scene
   - Timer
   - ScoreLabel
   - AudioStreamPLayer2D
   - AudioStreamPlayer

*** creating a new scene
1. go to the top of the center pane, and click on the plus.
   - this creates an empty unsaved scene
   - you must create a new root node.
     - click the '+' symbol in the upper left scene pane
     - search for Area2D: "a region of 2D space that detects other CollesionObject2Ds enteriinig or exiting it"
2. Menu->Scene->New Scene
   - select a root node, ie 2DScene - which will set your root node as a Node2D
   - or create one via the "+"

*** using a Area2D root node
- you must add a shape so the root node can interact with other objects and detect collisions or overlaps
  - CollisionShape2D
  - CollisionPolygon2D

*** add collisoinshape2D
- "+" -> CollisionShape2D
- add a shape
  - CollsionsShape2D node -> Inspector -> CollisionShape2D -> Shape -> <choose from dropdown>

*** add sprite2D
- the shape is only for background processing
- "+" -> Sprite2D
- drag and drop an image into Inspector->Sprite2D->Texture

*** refitting the collision shape
- currently the collision shape is being drawn first, then the sprite on top of it
- reorder so that the sprite gets drawn first, then the colision shape
- resize the collision shape, use transform if you need to


*** add paddle to game scene
- go to the game scene
- click the chain button in the upper left scene pain, the chain button is to the right of the "+"
- select which scene you want to add
