Controls

Use the scroll wheel to navigate across the x-y plane:

  • Default is Scroll mode. Scroll direction is determined by where you position the mouse over the simulation window.
  • Hold Shift to toggle Zoom mode.

Alternatively, you can use the buttons to toggle between modes.

Drag the ball to move it across on the x-y plane.
Its coordinates on the plane are relative to the bottom point of the ball.
