1.在头文件中声明3个变量：

public:

UPROPERTY(VisibleDefaultsOnly,Category="My Actor Propertys|Vector")

FVector WorldOrigin;

UPROPERTY(EditAnywhere,Category="My Actor Propertys|Vector")

FVector TickOffsetLocation;

UPROPERTY(EditAnywhere,Category="My Actor Propertys|Vector")

bool bMove;

2.在源文件中初始化

WorldOrigin = FVector (0.0f);

TickOffsetLocation = FVector (0.0f);

bMove = false;

3.修改Tick函数：

if(bMove ){

 AddActorRelativeOffset(TickOffsetLocation );

}
