Drag the Red Intended Trajectory line to change the Strike Angle

Red Ball Angle (Trajectory): 45°

Strike Angle: 23°

Legend:

Blue = axis of the balls (path Blue will follow)

Red = Intended path for Red

White = Strike angle (path of the mallet)

Adjust Strike Ratio: 51%

The Strike Angle is calculated as a percent of the angle between the Blue and Red lines, e.g., the "Strike Ratio". Adjust that with the + and - to account for horizontal "pull" resulting from the impact.
