# 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. ``` ## 示例效果: ![Untitled](Untitled.png)
