Yes! I'd recommend trying things out for yourself. Try out the normal version (available for free) here: http://sumrndm.site/hud-maker-ultra
To make a variable gauge, simply select the "Gauge" component, go to "Gauge Value", and then select the "Variable" tab. The gauge bar will now be the same as the number in the variable.
Also be sure to set the "Gauge Maximum" to the plain number you wish to represent the max fill (like 10 or something). You could even set the maximum value to also be based on a variable! 😁
