The Physics2D class is a Physics that works specifically in two d.
This is useful because it simplifies calculations especially related to checking if particles are bouncing off the walls of the space because it doesn't have to worry about the z dimension.
| Physics2D::Physics2D | ( | double | xWinSize, |
| double | yWinSize | ||
| ) |
Constructs a Physics2D object.
This calls Physics::Physics(), then initializes the size of the space.
| xWinSize | The size of the x dimension of this space. |
| yWinSize | The size of the y dimension of this space. |
