Taking the MouseMeasure.ahk Script to the Next Level, We Add Multiple Calculations for Going Around Corners

The original MouseMeasure.ahk script captures a single-length in a straight line—as a crow flies. While this works great for many applications, roads and highways generally wind over travel distances. Depending upon where you’re going, this can cause a significant variation in the total calculation. To return a more accurate overall estimate, we must break the measurement line into shorter segments.

Start the measurement with the Ctrl+LButton Hotkey, then click the left mouse button for each new leg of the journey. Press the Shift key to terminate the last leg and display the total distance.

The original form of the MouseMeasure.ahk script only allows for a sole straight line. To add more legs to our journey (at different angles), we must implement AutoHotkey techniques for:

  1. Terminating one segment and starting a new one.
  2. Tracking the position of each segment, its length, and the total distance traveled.
  3. Refreshing the screen to include all past legs as well as the new leg.
  4. Sending multiple saved data items for each leg to documents and forms.
