ICS3U1 Unit 2 Activity 1: Question 3

// Date Completed: July 18, 2017
// Purpose: Outputting written directions when given compass directions

// This line makes the button, btnDisplay wait for a mouse click
// When the button is clicked, the determineDirections function is called
btnDisplay.addEventListener(MouseEvent.CLICK, determineDirections);

// This line makes the textinputs: txtinOrigin wait for a mouse click
// When a textinput is clicked, the clearLabel 1 functions are called
txtinDirection.addEventListener(MouseEvent.CLICK, clearLabel1);

// This is the determineDirections function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function determineDirections(e:MouseEvent):void
{
    // Declare variables
    var Origin:String;
    var Initial:String;
    var Secondary:String;

    // Declaring source of variables
    Origin = String(txtinDirection.text);

    // If statements to determine the initial direction output
    if (Origin.charAt(0) == "N" || Origin.charAt(0) == "n")
    {
        Initial = "North"
    }

    else if (Origin.charAt(0) == "S" || Origin.charAt(0) == "s")
    {
        Initial = "South"
    }

    else if (Origin.charAt(0) == "E" || Origin.charAt(0) == "e")
    {
        Secondary = "East"
    }

    else if (Origin.charAt(0) == "W" || Origin.charAt(0) == "w")
    {
        Secondary = "West"
    }

    // If statements to determine the secondary direction output
    if (Origin.charAt(3) == "N" || Origin.charAt(3) == "n")
    {
        Initial = "North"
    }

    else if (Origin.charAt(3) == "S" || Origin.charAt(3) == "s")

    }

    else if (Origin.charAt(3) == "W" || Origin.charAt(3) == "w")
    {

    }

    //The label output
    lblInstructions.text = "Start facing " + Initial + ". Turn " + Origin.charAt(1) + Origin.charAt(2) + " degrees towards " + Secondary + ".";
}

// This is the clearLabel1 function
// e:MouseEvent is the click event experienced by the textinput
// void indicates that the function does not return a value
