I did some tests in video form, using only the GURPS Ruleset, without any extension.
In the video I will put a neutral token, a hostile token and an allied token.
Grid and token will be locked, I will test the movement with the directional arrows on the numeric keypad.
And the movement through the mouse, in the two positions of the hexagon.
The video will be silent because I speak Portuguese and I believe that nobody would understand, but I believe that the video can illustrate the situation well, I will make the same video in Fantasy Grounds Classic to show the tool that changes the unit of measure and its value.
The map is a simple 2048x2048 (72dpi) white jpg.
I hope this can help everyone.
