Components
| Component | Description |
|---|---|
| CircularObject | radius of round objects (e.g the ball) |
| Drawable | tag component that indicates that the entity should be rendered |
| Input | tag component that indicates that the entity interacts with the keyboard |
| Position | center of mass of the entity |
| RectangularObject | width and height of rectangular objects (e.g the paddles) |
| Scoreboard | scores of both players |
| ScoreListener | contains a function that is called whenever a player scores |
| ScoringBounds | the x coordinates of the scoring thresholds |
| Velocity | velocity of the entity |
| Wall | a line segment corresponding to a window wall and a corresponding normal vector |
