在 虚幻编辑器 中点击 文件File 下拉菜单然后选择 新建C类...New C Class... 命令 此时将显示 选择父类Choose Parent Class 菜单。可以选择要扩展的现有类将其功能添加到自己的类。选择 Actor因为其是可在场景中放置的最基本对象类型然后点击 下一步Next。 在 为新Actor命名Name Your New Actor 菜单中将Actor命名为 FloatingActor然后点击 创建类Create Class。 编辑C类
现在我们已创建C类将切换到Visual Studio并编辑代码。
在 Visual Studio 中找到默认情况下显示在窗口左侧的 解决方案浏览器然后用其找到 FloatingActor.h。在项目中它将位于 Games QuickStart Source QuickStart 下
