public var phase: TouchPhase;
public TouchPhase phase;
public phase as TouchPhase

Description

Describes the phase of the touch.

The touch phase refers to the action the finger has taken on the most recent frame update. Since a touch is tracked over its "lifetime" by the device, the start and end of a touch and movements in between can be reported on the frames they occur. The phase property can be used as the basis of a "switch' statement or as part of a more sophisitcated state handling system.

var startPos: Vector2;
var direction: Vector2;
var directionChosen: boolean;

function Update () { // Track a single touch as a direction control. if (Input.touchCount > 0) { var touch = Input.GetTouch(0); // Handle finger movements based on touch phase. switch (touch.phase) { // Record initial touch position. case TouchPhase.Began: startPos = touch.position; directionChosen = false; break; // Determine direction by comparing the current touch // position with the initial one. case TouchPhase.Moved: direction = touch.position - startPos; break; // Report that a direction has been chosen when the finger is lifted. case TouchPhase.Ended: directionChosen = true; break; } } if (directionChosen) { // Something that uses the chosen direction... } }
