+# Experimental
+
+- **功能描述：**  标明该类是试验性版本，当前没有文档描述，之后有可能废弃掉。
+- **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Experimental
+- **常用程度：★★★**
+
+标明该类是试验性版本，当前没有文档描述，之后有可能废弃掉。
+
+源码里的例子是Paper2D的类。这个标记会在类的元数据上加上{ "DevelopmentStatus", "Experimental" }。
+
+## 示例代码：
+
+```cpp
+/*
+(BlueprintType = true, DevelopmentStatus = Experimental, IncludePath = Class/Display/MyClass_Deprecated.h, IsBlueprintBase = true, ModuleRelativePath = Class/Display/MyClass_Deprecated.h)
+*/
+UCLASS(Blueprintable, Experimental)
+class INSIDER_API UMyClass_Experimental :public UObject
+{
+	GENERATED_BODY()
+public:
+	UPROPERTY(EditAnywhere, BlueprintReadWrite)
+		int32 MyProperty;
+	UFUNCTION(BlueprintCallable)
+		void MyFunc() {}
+};
+```
