现在是只能远近缩放 不能平移。求助大家

请您再详细的描述一下，我们比较好判断^_^ 另外，我们不推荐直接把代码一大堆贴出来，其实别人也确实没时间看的，不是吗，呵呵^_^~ |

现在是只能远近缩放 不能平移摄像机 感觉我写的不对,但是也看不出什么地方出错了?所以就贴出来了 按键时也有反应.之后又返回了,达不到平移的效果,希望能像这样平移http://www.xiaos8.com/uploads/flash/factory.swf 请 DDM君 指点指点 |

您平移的时候必须要同时平移camera的target的位置也要跟着平移才行，但是当然不能直接去平移target对应的物体。 不知道这样讲对您有没有帮助，呵呵。 |
