unity3d游戏开发之IOS自定义游戏摇杆与飞机平滑的移动(十一).docVIP

移动开发游戏中使用到的触摸游戏摇杆在iPhone上是非常普遍的，毕竟是全触摸屏手机，今天MOMO 通过一个小例子和大家讨论 ////////////////////////////////////////////////////////////// // Joystick.js // Penelope iPhone Tutorial // // Joystick creates a movable joystick (via GUITexture) that // handles touch input, taps, and phases. Dead zones can control // where the joystick input gets picked up and can be normalized. // // Optionally, you can enable the touchPad property from the editor // to treat this Joystick as a TouchPad. A TouchPad allows the finger // to touch down at any point and it tracks the movement relatively // without moving the graphic ////////////////////////////////////////////////////////////// ?? @script RequireComponent( GUITexture ) ?? // A simple class for bounding how far the GUITexture will move class Boundary { ? ? var min : Vector2 = Vector2.zero; ? ? var max : Vector2 = Vector2.zero; } ?? static private var joysticks : Joystick[];? ?? ?? ?? ?? ?? ???// A static collection of all joysticks static private var enumeratedJoysticks : boolean = false; static private var tapTimeDelta : float = 0.3;? ?? ?? ?? ?? ? // Time allowed between taps ?? var touchPad : boolean;? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ? // Is this a TouchPad? var touchZone : Rect; var deadZone : Vector2 = Vector2.zero;? ?? ?? ?? ?? ?? ?? ?? ?// Control when position is output var normalize : boolean = false;? ?? ?? ?? ?? ?? ?? ?? ?? ???// Normalize output after the dead-zone? var position : Vector2;? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ? // [-1, 1] in x,y var tapCount : int;? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ???// Current tap count ?? private var lastFingerId = -1;? ?? ?? ?? ?? ?? ?? ?? ?? ?? ???// Finger last used for this joystick private var tapTimeWindow : float;? ?? ?? ?? ?? ?? ?? ?? ?? ? // How much time there is left for a tap to occur private var fingerDownPos : Vector2; private var fingerDownTime : float; private var firstDeltaTime : float = 0.5; ?? private var gui : GUITexture;? ?? ?? ?? ?? ?? ?? ?? ?? ?? ???// Joystick gr
