标题: Flash3D编程技巧_全景浏览的鼠标交互

1. 注册侦听器

Java代码

addEventListener(Event.ENTER_FRAME, onEnterFrame);
stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);

addEventListener(Event.ENTER_FRAME, onEnterFrame);
stage.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown);
stage.addEventListener(MouseEvent.MOUSE_UP, onMouseUp);

2. MouseDown触发函数

Java代码

// 保存鼠标点击的摄像机参数和鼠标坐标信息

private function onMouseDown(event:MouseEvent):void
{
      lastPanAngle = camera.panAngle;
      lastTiltAngle = camera.tiltAngle;
      lastMouseX = stage.mouseX;
      lastMouseY = stage.mouseY;
      move = ***e;
      stage.addEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);
}

// 保存鼠标点击的摄像机参数和鼠标坐标信息
private function onMouseDown(event:MouseEvent):void
{
lastPanAngle = camera.panAngle;
lastTiltAngle = camera.tiltAngle;
lastMouseX = stage.mouseX;
lastMouseY = stage.mouseY;
move = ***e;
stage.addEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);
}

3. MouseUp触发函数

Java代码

private function onMouseUp(event:MouseEvent):void
{
      move = false;
      stage.removeEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);
}

private function onMouseUp(event:MouseEvent):void
{
move = false;
stage.removeEventListener(Event.MOUSE_LEAVE, onStageMouseLeave);
}

4. 每帧都调用的onEnterFrame

Java代码

private function onEnterFrame(event:Event):void
{
      if (move) {
         camera.panAngle = 0.3*(stage.mouseX - lastMouseX) + lastPanAngle;
         camera.tiltAngle = 0.3*(stage.mouseY - lastMouseY) + lastTiltAngle;
      }

      camera.hover();
      view.render();
}

private function onEnterFrame(event:Event):void
{
if (move) {
camera.panAngle = 0.3*(stage.mouseX - lastMouseX) + lastPanAngle;
camera.tiltAngle = 0.3*(stage.mouseY - lastMouseY) + lastTiltAngle;
}

camera.hover();
view.render();
}
