Methods

`Static` make

make(sim, width, height, opt_thickness?, opt_center?): number
Makes four walls of given thickness, with interior rectangle of given width and height and centered at the given location. Each wall is given infinite mass. The walls are named WALL_BOTTOM, WALL_TOP, WALL_LEFT, WALL_RIGHT.
Parameters
- sim: RigidBodySim
  the RigidBodySim to which the walls are added
- width: number
  the horizontal distance between the walls
- height: number
  the vertical distance between the walls
- Optional opt_thickness: number
  the thickness of each wall; default is 1.
- Optional opt_center: Vector
  location of the center of the rectangle formed by the walls, in world coordinates; default is origin.
Returns number
suggested zero potential energy level -- the top of the bottom wall.
- Defined in lab/engine2D/Walls.ts:43

`Static` make2

make2(sim, rect, opt_thickness?): number
Makes four walls of given thickness, with interior rectangle equal to the given rectangle.
Parameters
- sim: RigidBodySim
  the RigidBodySim to which the walls are added
- rect: DoubleRect
  the interior rectangle of the walls
- Optional opt_thickness: number
  the thickness of each wall
Returns number
suggested zero potential energy level -- the top of the bottom wall.
- Defined in lab/engine2D/Walls.ts:98
