# Placeable
- **功能描述:** 标明该Actor可以放置在关卡里。
- **引擎模块:** Scene
- **元数据类型:** bool
- **作用机制:** 在ClassFlags中移除[CLASS_NotPlaceable](../../../../Flags/EClassFlags/CLASS_NotPlaceable.md)
- **关联项:** [NotPlaceable](../NotPlaceable/NotPlaceable.md)
- **常用程度:★★★**
标明该Actor可以放置在关卡里。
默认情况下是placeable的因此源码里目前没有用到Placeable的地方。
子类可使用NotPlaceable说明符覆盖此标志正如AInfo之类的上面自己设置NotPlaceable。
指示可在编辑器中创建此类而且可将此类放置到关卡、UI场景或蓝图取决于类类型中。此标志会传播到所有子类
placeable没法清除父类的notplaceable标记。
## 示例代码:
```cpp
UCLASS(Blueprintable, BlueprintType,placeable)
class INSIDER_API AMyActor_Placeable :public AMyActor_NotPlaceable
{
GENERATED_BODY()
};
error : The 'placeable' specifier cannot override a 'nonplaceable' base class. Classes are assumed to be placeable by default. Consider whether using the 'abstract' specifier on the base class would work.
```
