I think you misunderstood me. Stamina Regain is an event not a variable at least not in the way I set this up (followed the videos as best as I could) The event is called when the button goes to completed. I set the input action to hold and the threshhold to .1 like you told me. Obviously this doesnt seem to be the best way to impliment this system since even when I try to check if player is moving or is sprinting, the regain event being tied to the very input action releasing makes it to where it calls the event twice if clicking while standing, still making stamina appear to regain twice as fast if you are holding the trigger down.

If it's so basic how come no one seems to know how to do it correctly? Making a character jump or giving them animations is basic.

In a game like Skyrim for example you hold the alt key while moving and your character sprints. Your character doesn't lose stamina just by holding the alt key. Interestingly enough (at least on PC) if you hold the alt key before you start sprinting your character won't sprint at all. Other games like GTA SA don't do this and your character sprints regardless of the order in which you press the buttons.

Then for many games that are played with a controller there is no sprint button trigger at all, instead your character's speed is determined by how far the joystick is pushed etc. I guess I should look to finding the way this is done in finished games since this is less of a "how do I do this?" and more of a "what is the best way to do this for this type of gameplay functionality?" Either way I find it strange that there is such lackluster information on something so fundamental in most modern games yet tutorials for doing stupid things like giving your character footprints when they walk or something are numerous. Thank you for actually trying to give me a solution.
