现在我们可以先补全LineTraceSingleByObjectType()函数求交成功后的代码,即设置_selectedActor并执行ShowSelectedActorBox(),同时可以打印一些调试信息,结果如下图所示: 之后的工作似乎是顺理成章的,我们在键盘方向键对应的回调函数中,直接调整selectedActor的空间位置,并更新高亮选框使其与Actor对象一起运动: 但是如果此...

DrawDebugLine(GetWorld(), StartLocation, EndLocation, FColor::Blue, false, 5.f); DrawDebugPoint(GetWorld(), HitResult.ImpactPoint, 10.f, FColor::Red, false, 5.f); } } ``` 以上是LineTraceMultiByProfile的基本用法,具体可以根据实际需求进行调整。你可以根据自己的需要,指定不同的追踪参数和...
LineTraceMultiByProfile是UE5中的一种射线检测方法,用于检测一条射线与场景中的多个物体是否有交集。与常规的单个射线检测相比,LineTraceMultiByProfile可以一次性检测多个物体,从而提高游戏性能和开发效率。 使用LineTraceMultiByProfile的第一步是设置检测的起点和方向。可以通过设置起点的坐标和方向向量来定义一条射线。
