Input.inputString

Description

Returns the keyboard input entered this frame. (Read Only)

Only ASCII characters are contained in the inputString.

The string can contain two special characters which should be handled: Character "\b" represents backspace.
Character "\n" represents return or enter.

// Reading typed input from the keyboard
// (eg, the user entering their name).
// You need to attach this script to an object with
// a GUIText component.

var gt: GUIText;

function Start() {
    gt = GetComponent.<GUIText>();
}

function Update () {
    for (var c : char in Input.inputString) {
        // Backspace - Remove the last character
        if (c == "\b"[0]) {
            if (gt.text.Length != 0)
                gt.text = gt.text.Substring(0, gt.text.Length - 1);
        }
        // End of entry
        else if (c == "\n"[0] || c == "\r"[0]) {// "\n" for Mac, "\r" for windows.
            print ("User entered their name: " + gt.text);
        }
        // Normal text input - just append to the end
        else {
            gt.text += c;
        }
