我在as3中多點觸控有點問題。 最近開始一個與我的學生實踐有關的項目。 這是一個針對android的小遊戲。 用於控制兩個虛擬遊戲杆，這是他們的問題。 只要我單獨使用其中一個或另一個，所有工作都很好。但是，當我嘗試同時使用兩個時，其中一個被阻止，並且移動的對象開始隨機移動，我無法控制它。多點觸控as3問題
這裏是我的代碼：
joystick.as：
package com.controls {
import flash.events.TouchEvent;
import flash.ui.Multitouch;
import flash.ui.MultitouchInputMode;
import flash.display.Sprite;
import flash.events.Event;
import flash.display.MovieClip;
import flash.geom.Rectangle;
import com.controls.JoystickKnob;
import com.Hero;
import com.Fire;
import com.greensock.*;
import com.greensock.easing.*;
public class Joystick extends MovieClip {
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
private var my_x:Number;
private var my_y:Number;
private var knob:JoystickKnob;
private var hero:Hero;
private var fire:Fire;
private var knob_tween:TweenLite;
public function Joystick(margin_left, margin_bottom, hero_mc) {
var circle:Sprite = new Sprite();
circle.graphics.beginFill(0x696969);
circle.graphics.drawCircle(50, 50, 60);
circle.graphics.endFill();
addChild(circle);
my_x = margin_left;
my_y = margin_bottom;
hero = hero_mc;
if (stage) {
init();
} else {
addEventListener(Event.ADDED_TO_STAGE,init);
}
}
private function init(e:Event = null):void {
if (hasEventListener(Event.ADDED_TO_STAGE)) {
removeEventListener(Event.ADDED_TO_STAGE,init);
}
this.x = my_x + this.width/2;
this.y = stage.stageHeight - my_y - this.height/2;
knob = new JoystickKnob();
knob.x = 0;
knob.y = 0;
knob.origin_x = 0;
knob.origin_y = 0;
addChild(knob);
this.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin, true);
knob.addEventListener(TouchEvent.TOUCH_MOVE, onTouchMove, true);
stage.addEventListener(TouchEvent.TOUCH_END, onTouchEnd, true);
knob.buttonMode = true;
}
private function onTouchBegin(event:TouchEvent):void {
knob.x = this.mouseX;
knob.y = this.mouseY;
onTouchMove(null);
}
private function onTouchMove(event:TouchEvent):void {
if (knob_tween) {
knob_tween.kill();
}
this.addEventListener(Event.ENTER_FRAME, knobMoved);
knob.startDrag(false, new Rectangle(- this.width /2, - this.height /2, this.width, this.height));
}
private function knobMoved(event:Event):void {
// LEFT OR RIGHT
if (knob.x > 15) {
hero.move_right = true;
hero.move_left = false;
} else if (knob.x < -15) {
hero.move_right = false;
hero.move_left = true;
} else {
hero.move_right = false;
hero.move_left = false;
}
// UP OR DOWN
if (knob.y > 15) {
hero.move_down = true;
hero.move_up = false;
} else if (knob.y < -15) {
hero.move_down = false;
hero.move_up = true;
} else {
hero.move_down = false;
hero.move_up = false;
}
}
private function onTouchEnd(event:TouchEvent):void {
knob.stopDrag();
hero.move_left = false;
hero.move_up = false;
hero.move_right = false;
hero.move_down = false;
if (this.hasEventListener(Event.ENTER_FRAME)) {
this.removeEventListener(Event.ENTER_FRAME, knobMoved);
}
mover();
}
private function mover():void {
knob_tween = new TweenLite(knob, 0.5, {x: knob.origin_x, y:knob.origin_y, ease:Bounce.easeOut});
}
}
}
joystickKnob.as：
package com.controls {
import flash.display.Sprite;
import flash.display.MovieClip;
public class JoystickKnob extends MovieClip {
private var _origin_x:Number;
private var _origin_y:Number;
private var knob:Class;
public function JoystickKnob() {
var circle:Sprite = new Sprite();
circle.graphics.beginFill(0x32CD32);
circle.graphics.drawCircle(50, 50, 35);
circle.graphics.endFill();
addChild(circle);
}
public function get origin_x():Number {
return _origin_x;
}
public function set origin_x(o_x:Number):void {
_origin_x = o_x;
}
public function get origin_y():Number {
return _origin_x;
}
public function set origin_y(o_y:Number):void {
_origin_y = o_y;
}
}
}
第二操縱手柄的代碼看起來牛逼他是一樣的，只是它存儲在文件joystick2.as，joystickKnob2.as中。
這是主類我的程序：
package com {
import flash.events.TouchEvent;
import flash.display.MovieClip;
import flash.events.MouseEvent;
import com.controls.Joystick;
import com.controls.Joystick2;
import com.Hero;
import com.Fire;
public class MyApp extends MovieClip {
private var joystick:Joystick;
private var hero:Hero;
private var joystick2:Joystick2;
private var fire:Fire;
public function MyApp() {
hero = new Hero();
hero.x = stage.stageWidth/1.7;
hero.y = stage.stageHeight/1.7;
addChild(hero);
fire = new Fire();
fire.x = stage.stageWidth/1.7;
fire.y = stage.stageHeight/1.7;
addChild(fire);
joystick = new Joystick(-350, 100, hero);
addChild(joystick);
joystick2 = new Joystick2(600, 100, fire);
addChild(joystick2);
}
}
}
當使用兩個操縱桿的同時，問題也出現與旋鈕圖形 - 而不是在一個特定的區域中移動，其中一個幾乎總是移動到屏幕的另一端，靠近第二個操縱桿的區域。
有沒有人遇到過這樣的問題，並知道如何補救？
