几周前我问了一个关于类似问题的问题,但在 Starling 框架内(Sprite 上的 Starling TouchEvent)
现在,我正在使用 Away3d 开发另一个移动应用程序/游戏。我似乎在触摸/点击移动的球体或盒子时遇到了同样的问题。当球体不移动时,我可以在它的位置准确地点击它,但是当它旋转时,点击事件不会非常准确地触发。这只发生在移动设备上(在 Android 4.2.2 上测试:Nexus7/Galaxy S2 和 iOS:iPad2/iPad Retina)
package {

[SWF(frameRate="60")]
public class Main extends Sprite {
private var _container:ObjectContainer3D;
private var _view:View3D;
private var _sphere:Mesh;
public function Main()
{
super();
addEventListener(Event.ADDED_TO_STAGE, onAdded_toStage);
}
private function onAdded_toStage(e:Event):void {
removeEventListener(Event.ADDED_TO_STAGE, onAdded_toStage);
stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.addEventListener(Event.RESIZE, onResize_stage);
init3d();
}
private function onResize_stage(e:Event):void {
_view.width = stage.stageWidth;
_view.height = stage.stageHeight;
}
private function onEnter_frame(e:Event):void {
_container.rotationY += 1;
_view.render();
}
private function onClick_sphere(e:MouseEvent3D):void {
//reposition the sphere
var deg:Number = Math.random() * 360;
_sphere.x = 250 * Math.cos(deg);
_sphere.z = 250 * Math.sin(deg);
_sphere.y = 80 + (Math.random() * 40);
}
private function init3d():void {
//create the 3d-view
_view = new View3D();
_view.width = stage.stageWidth;
_view.height = stage.stageWidth;
addChild(_view);
//create a cub
_view.camera.z = -400;
_view.camera.y = 75;
_view.camera.lookAt(new Vector3D(0, 125, 0));
//create container
_container = new ObjectContainer3D();
_view.scene.addChild(_container);
//create sphere to tap
_sphere = new Mesh(new SphereGeometry(10));
_sphere.pickingCollider = PickingColliderType.AS3_FIRST_ENCOUNTERED;
_sphere.y = 100;
_sphere.z = -250;
_sphere.mouseEnabled = true;
_sphere.addEventListener(MouseEvent3D.CLICK , onClick_sphere);
_container.addChild(_sphere);
var stats:AwayStats = new AwayStats(_view);
addChild(stats);
addEventListener(Event.ENTER_FRAME, onEnter_frame);
}
}
注意:我还尝试了不同的帧速率、更多事件(Mouse_up、down 等)、不同的选择器。
由于这个问题也发生在 2d 移动精灵(在椋鸟中),我猜这可能与 Stage3D 或 AIR 相关,而不是 starling/away3d。
有人有什么建议吗?也许我忘记在 app.xml 中设置一些东西?
