在源码实现中,【相对坐标】以【FVector】类型成员变量存储于【SceneComponent】组件的【RelativeLocation】中,所以可以直接获取出来,也提供了对应的修改函数,修改后会同时更新上述【绝对坐标】中的三维转换矩阵。同理【相对旋转】、【相对缩放】也是以类似独立字段进行存储: 1)设置:【SceneComponent::SetRelativeLocation 函...

调用如下函数: MSkeletaMeshComponent->SetRelativeLocation(FVector(0,0,-90)); 显示效果: MSkeletaMeshComponent->SetRelativeLocation(FVector(0,0,-160)); MSkeletaMeshComponent->SetRelativeLocation(FVector(0,90,-90)); MSkeletaMeshComponent->SetRelativeLocation(FVector(90,0,-90)); 总结: 改变x的值,...
SetActorLocation 设置Actor的位置,应该是全局位置 GetActorLocation 获取Actor的位置 SetRelativeTransform 设置相对的transform SetLifeSpan 设置Actor存活时间 DestoryActor 删除Actor DestoryComponent 删除组件 Get Owner 获取拥有者 SetVisibility 设置显示或隐藏 GetActorForwardVector 得到Actor的正方向 GetActorRightVector ...
GetMesh()->SetRelativeLocation(FVector(0,0,-90)); //设置模型面朝方向 GetMesh()->SetRelativeRotation(FRotator(0,-90,0)); 编译一下,回到编辑器中,发现我们的摄像机已经添加了进去。 完整代码如下。 1) PlayingCharacter.h // Fill out your copyright notice in the Description page of Project Set...
