String method for scripting?

Anybody knows what was the string joystick method about? I wanted to create a few scripts and I remember reading about it long time ago on RTS. From what I remember it gave good results with less time spent than frame-by-frame scripting.

I guess it was something about attaching the string to the joystick or gamepad somehow and using on-the-fly recording. Thanks in advance for any clues :slight_smile:

I found some mentions about it in some archived posts from rts but nothing specific:
