UE4 VR 瞬移 Teleport 一
来源：互联网 发布：北风网大数据 编辑：程序博客网 时间：2024/06/10 21:58
大家都知道在U3D瞬移很好做，用steamvr提供的脚本或者用VRTK加上寻路网格就可以轻松完成
那么在UE4中呢
下面我们共同研究一线 在UE4中如何利用寻路网格做vr瞬移
首先构建一个C++类继承于SceneComponent类
我将其命名为RunebergVR_Teleporter
讲头文件改为
include “Components/ActorComponent.h”
include “Components/SplineComponent.h”
include “Components/SplineMeshComponent.h”
include “RunebergVR_Teleporter.generated.h”
为了省事。。额。。我还是决定上代码吧
头文件如下利用SplineMesh的特性形成弯曲的曲线，在CPP中实现具体实现原始点到终点的弯曲

找到工程配置例如我的如图 
讲PublicDependencyModuleNames.AddRange（）内容改为如图
好了 现在就可以调用了
