# MustBeLevelActor
|
|||
|
|
|
|||
|
|
- **使用位置：** UPROPERTY
|
|||
|
|
- **引擎模块：** Object Property
|
|||
|
|
- **元数据类型：** bool
|
|||
|
|
|
|||
|
|
意思是这个必须是场景里的Actor，而不是LevelScriptActor的意思。
|
|||
|
|
|
|||
|
|
触发时机在用箭头选择的当前选中actor的时候。

## 源码中遇见：
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
if (FObjectPropertyBase* ObjectProperty = CastField<FObjectPropertyBase>(Property))
|
|||
|
|
{
|
|||
|
|
ObjectClass = ObjectProperty->PropertyClass;
|
|||
|
|
bMustBeLevelActor = ObjectProperty->GetOwnerProperty()->GetBoolMetaData(TEXT("MustBeLevelActor"));
|
|||
|
|
RequiredInterface = ObjectProperty->GetOwnerProperty()->GetClassMetaData(TEXT("MustImplement"));
|
|||
|
|
}
|
|||
|
|
```
