【UnLua】在 Lua 中定义 UE 反射类型
用法
- 启动编辑器时遍历 Defines 目录下 lua 脚本来加载 UE 反射类型（开个临时的 Lua VM 即可）
- 直接像
-- define a uenum in lua
UEnum.EEnumGuestSomethingElse {Value1 = 1;Value2 = 2;
}-- use it like a native uenum
UnLua.Log(UE.EEnumGuestSomethingElse.Value2)UClass { Config = "Game" }.
MoviePipelineExampleRuntimeExecutor(UE.MoviePipelinePythonHostExecutor, UE.IXXXInteface) {activeMoviePipeline = UE.UProperty {};exampleArray = UE.TArray(str);exampleDict = UE.TMap(str, bool);on_map_load = UE.UFunction {override = true;params = { };}
}====== UEnum ======
C++
UENUM(BlueprintType)
enum class ETest : uint8
{Walking,Running,Sprinting,ALS_MAX UMETA(DisplayName="ALS MAX")
};
Test.generated.h
#include "UObject/ObjectMacros.h"
#include "UObject/ScriptMacros.h"#define FOREACH_ENUM_ETEST(op) \op(ETest::Walking) \op(ETest::Running) \op(ETest::Sprinting) \op(ETest::ALS_MAX)enum class ETest : uint8;
template<> struct TIsUEnumClass<ETest> { enum { Value = true }; };
template<> LYRAGAME_API UEnum* StaticEnum<ETest>();
Test.gen.cpp
- 生成代码入口 FNativeClassHeaderGenerator::ExportGeneratedEnumInitCode
- 构造 UEnum 入口 UECodeGen_Private::ConstructUEnum
- 构造时机：static 注册，所以 C++ 启动时

- 创建入口 FPythonGeneratedEnumBuilder::RegisterDescriptors
- 创建时机 uenum -> GenerateEnum
