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.
|
|||
|
```
