Variable to shorten controller axis command

[cant-turn-left]

I’m trying to make a variable so that I don’t have to write Controller1.Axis3 way too many times.
For some reason it doesn’t like doubles but I really don’t want to risk using auto. Any help would be appreciated, I’m probably just being dumb. Thanks!

Controller1.Axis3 is an instance of a controller::axis class (actually a reference to one), you could do this
(use another reference to it)

    const vex::controller::axis &a3 = Controller.Axis3;

    while(1) {
        Brain.Screen.printAt( 100, 220, "Axis3 : %4d", a3.position() );
        this_thread::sleep_for(10);
    }

or this

    const auto &a3 = Controller.Axis3;

    while(1) {
        Brain.Screen.printAt( 100, 220, "Axis3 : %4d", a3.position() );
        this_thread::sleep_for(10);
    }

or if all you really need is to use the value of the axis several times, perhaps this.

    while(1) {
        // p will hold last position of axis3, it need updating each time through the loop
        int p = Controller.Axis3.position();

        Brain.Screen.printAt( 100, 220, "Axis3 : %4d", p );
        this_thread::sleep_for(10);
    }
