是的。
这段代码应该可以帮助你。它可能超出您的需要,但它有效。:) 取自Adobe 网站:
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
var mySprite:Sprite = new Sprite();
mySprite.graphics.beginFill(0x336699);
mySprite.graphics.drawRect(0,0,40,40);
addChild(mySprite);
var myTextField:TextField = new TextField();
addChild(myTextField);
myTextField.width = 200;
myTextField.height = 20;
var touchMoveID:int = 0;
mySprite.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchBegin);
function onTouchBegin(event:TouchEvent) {
if(touchMoveID != 0) {
myTextField.text = "already moving. ignoring new touch";
return;
}
touchMoveID = event.touchPointID;
myTextField.text = "touch begin" + event.touchPointID;
stage.addEventListener(TouchEvent.TOUCH_MOVE, onTouchMove);
stage.addEventListener(TouchEvent.TOUCH_END, onTouchEnd);
}
function onTouchMove(event:TouchEvent) {
if(event.touchPointID != touchMoveID) {
myTextField.text = "ignoring unrelated touch";
return;
}
mySprite.x = event.stageX;
mySprite.y = event.stageY;
myTextField.text = "touch move" + event.touchPointID;
}
function onTouchEnd(event:TouchEvent) {
if(event.touchPointID != touchMoveID) {
myTextField.text = "ignoring unrelated touch end";
return;
}
touchMoveID = 0;
stage.removeEventListener(TouchEvent.TOUCH_MOVE, onTouchMove);
stage.removeEventListener(TouchEvent.TOUCH_END, onTouchEnd);
myTextField.text = "touch end" + event.touchPointID;
}
