photoshop 制作罗盘游戏中罗盘指针旋转动画
/>在本小节的实例学习中，将制作罗盘游戏中罗盘指针旋转的动画效果。如图10-98所示，为本实例的完成效果。 
图10-98 完成效果技术提示
在本实例的制作过程中将通过使用“动作”调板制作罗盘的指针图像，并创建远程切片制作出通过按钮控制指针旋转的动画效果。如图10-99所示，为本实例的制作流程。 
图10-99 制作流程
制作步骤
（1）启动Photoshop，打开上一章节保存的“罗盘背景.psd”文件。然后再打开本书附带光盘\Chapter-10\“旋转指针.psd”文件，使用
“移动”工具，将文件中的指针图像，拖动复制到“罗盘背景.psd”文档中，如图10-100所示。
提示：该步骤是在动画帧为第1帧的状态上完成。

（7）在“图层”调板中显示并选择“组 2”图层组。参照上面设置动作的方法，再新建“动作 2”并开始记录，然后将“组 2”图层组复制，再执行“自由变换”命令，将复制的图像逆时针方向旋转15度，之后停止“动作 2”的记录，如图10-106所示。
提示：在操作该步骤时确定第1帧动画为选择状态。
