# EarlyAccessPreview - **功能描述:** 标明该类是早期预览版,比试验版要更完善一些,但还是没到产品级。 - **引擎模块:** Development - **元数据类型:** bool - **作用机制:** 在Meta中添加[DevelopmentStatus](../../../../Meta/Development/DevelopmentStatus.md),将类标记为EarlyAccess - **常用程度:★★★** 标明该类是早期预览版,比试验版要更完善一些,但还是没到产品级。 这个标记会在类的元数据上加上{ "DevelopmentStatus", "EarlyAccess" }。 ## 示例代码: ```cpp //(BlueprintType = true, DevelopmentStatus = EarlyAccess, IncludePath = Class/Display/MyClass_Deprecated.h, IsBlueprintBase = true, ModuleRelativePath = Class/Display/MyClass_Deprecated.h) UCLASS(Blueprintable, EarlyAccessPreview) class INSIDER_API UMyClass_EarlyAccessPreview :public UObject { GENERATED_BODY() public: UPROPERTY(EditAnywhere, BlueprintReadWrite) int32 MyProperty; UFUNCTION(BlueprintCallable) void MyFunc() {} }; ``` ## 示例结果: ![Untitled](Untitled.png)
