在角色的头文件中，添加一个布尔变量，设为共有状态，用来判断是否携带目标物体，并暴露给蓝图，类型为仅蓝图可读
UPROPERTY(BlueprintReadOnly,Category="Gameplay") bool bIsCarryingObjective;
当NotifyActorBeginOverlap发生时，检查是否与FPSCharacter中的角色发生重叠
AFPSCharacter* MyCharacter = Cast<AFPSCharacter>(OtherActor); if (MyCharacter) { MyCharacter->bIsCarryingObjective = true; Destroy(); }
