# NonTransactional
|
|||
|
|
|
|||
|
|
- **功能描述：** 对该属性的改变操作，不会被包含进编辑器的Undo/Redo命令中。
|
|||
|
|
|
|||
|
|
- **元数据类型：** bool
|
|||
|
|
- **引擎模块：** Editor
|
|||
|
|
- **作用机制：** 在PropertyFlags中加入[CPF_NonTransactional](../../../../Flags/EPropertyFlags/CPF_NonTransactional.md)
|
|||
|
|
- **常用程度：** ★★
|
|||
|
|
|
|||
|
|
指定该属性的改变，不能在编辑器中通过Ctrl+Z来撤销或Ctrl+Y来重做。在Actor或在BP的Class Defautls都可以生效。
|
|||
|
|
|
|||
|
|
## 测试代码：
|
|||
|
|
|
|||
|
|
```jsx
|
|||
|
|
UCLASS(Blueprintable, BlueprintType)
|
|||
|
|
class INSIDER_API AMyProperty_Transaction :public AActor
|
|||
|
|
{
|
|||
|
|
public:
|
|||
|
|
GENERATED_BODY()
|
|||
|
|
public:
|
|||
|
|
UPROPERTY(EditAnywhere, BlueprintReadWrite,NonTransactional,Category = Transaction)
|
|||
|
|
int32 MyInt_NonTransactional= 123;
|
|||
|
|
UPROPERTY(EditAnywhere, BlueprintReadWrite,Category = Transaction)
|
|||
|
|
int32 MyInt_Transactional = 123;
|
|||
|
|
};
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 蓝图表现：
|
|||
|
|
|
|||
|
|
在MyInt_Transactional 上可以撤销之前的输入，而MyInt_NonTransactional上的输入无法用Ctrl+Z撤销。
