## Property类型判断
- UStructProperty：结构体
- UMapProperty：TMap
- UArrayProperty：TArray
属性判断是否是数组或是Map
```c++
FProperty* PropertyThatChanged = PropertyChangedEvent.Property;
if ( PropertyThatChanged != nullptr )
{
    if (PropertyThatChanged->IsA(FArrayProperty::StaticClass()))
    {
        FArrayProperty* ArrayProp = CastField<FArrayProperty>(PropertyThatChanged);
        FProperty* InnerProp = ArrayProp->Inner;
        if (InnerProp->IsA(FStructProperty::StaticClass()))
        {
            const FToonRampData* ToonRampData = ArrayProp->ContainerPtrToValuePtr<FToonRampData>(InnerProp, 0);
            if(ToonRampData)
            {
            }
        }
    }else if(PropertyThatChanged->IsA(FMapProperty::StaticClass()))
    {
        FArrayProperty* ArrayProp = CastField<FArrayProperty>(PropertyThatChanged);
        FProperty* InnerProp = ArrayProp->Inner;
        if (InnerProp->IsA(FStructProperty::StaticClass()))
        {
            const FToonRampData* ToonRampData = ArrayProp->ContainerPtrToValuePtr<FToonRampData>(InnerProp, 0);
            if(ToonRampData)
            {
            }
        }
    }
    }
```
## 属性变化回调函数
```c#
virtual void EditorApplyTranslation(const FVector& DeltaTranslation, bool bAltDown, bool bShiftDown, bool bCtrlDown) override;
virtual void EditorApplyRotation(const FRotator& DeltaRotation, bool bAltDown, bool bShiftDown, bool bCtrlDown) override;
virtual void EditorApplyScale(const FVector& DeltaScale, const FVector* PivotLocation, bool bAltDown, bool bShiftDown, bool bCtrlDown) override;
virtual void PostEditMove(bool bFinished) override;
virtual void PostEditComponentMove(bool bFinished) override;
```
# 没有Struct()却可以在蓝图找到类型问题笔记
## Traits
大概率是这个
```c++

    enum
    {
        WithIdenticalViaEquality = true,

        WithZeroConstructor = true,
    };
};
IMPLEMENT_STRUCT(Box2D);
```

Struct的收集
对于Struct，我们先来看上篇里生成的代码：
```c++
static FCompiledInDeferStruct Z_CompiledInDeferStruct_UScriptStruct_FMyStruct(FMyStruct::StaticStruct, TEXT("/Script/Hello"), TEXT("MyStruct"), false, nullptr, nullptr);  //延迟注册
static struct FScriptStruct_Hello_StaticRegisterNativesFMyStruct
{
    FScriptStruct_Hello_StaticRegisterNativesFMyStruct()
    {
        UScriptStruct::DeferCppStructOps(FName(TEXT("MyStruct")),new UScriptStruct::TCppStructOps<FMyStruct>);
    }
} ScriptStruct_Hello_StaticRegisterNativesFMyStruct;  
```
https://zhuanlan.zhihu.com/p/59553490
ICppStructOps的作用
很多朋友在看源码的时候，可能会对UScriptStruct里定义的ICppStructOps类以及模板子类`TCppStructOps<CPPSTRUCT>`感到疑惑。其实它们是C++的一种常见的架构模式，用一个虚函数基类定义一些公共操作，再用一个具体模板子类来实现，从而既可以保存类型，又可以有公共操作接口。
针对于UE4这里来说，ICppStructOps就定义了这个结构的一些公共操作。而探测这个C++结构的一些特性就交给了`TCppStructOps<CPPSTRUCT>`类里的`TStructOpsTypeTraits<CPPSTRUCT>`。一些C++结构的信息不能通过模板探测出来的，就需要我们手动标记提供了，所以具体的代码是：
```c++
template <class CPPSTRUCT>
struct TStructOpsTypeTraitsBase2
{
    enum
    {
        WithZeroConstructor = false, // 0构造，内存清零后就可以了，说明这个结构的默认值就是0
        WithNoInitConstructor = false, // 有个ForceInit的参数的构造，用来专门构造出0值结构来
        WithNoDestructor = false, // 是否没有结构有自定义的析构函数， 如果没有析构的话，DestroyStruct里面就可以省略调用析构函数了。默认是有的。结构如果是pod类型，则肯定没有析构。
        WithCopy = !TIsPODType<CPPSTRUCT>::Value, // 是否结构有自定义的=赋值函数。如果没有的话，在CopyScriptStruct的时候就只需要拷贝内存就可以了
        WithIdenticalViaEquality = false, // 用==来比较结构
        WithIdentical = false, // 有一个自定义的Identical函数来专门用来比较，和WithIdenticalViaEquality互斥
        WithExportTextItem = false, // 有一个ExportTextItem函数来把结构值导出为字符串
        WithImportTextItem = false, // 有一个ImportTextItem函数把字符串导进结构值
        WithAddStructReferencedObjects = false, // 有一个AddStructReferencedObjects函数用来添加结构额外的引用对象
        WithSerializer = false, // 有一个Serialize函数用来序列化
        WithStructuredSerializer = false, // 有一个结构结构Serialize函数用来序列化
        WithPostSerialize = false, // 有一个PostSerialize回调用来在序列化后调用
        WithNetSerializer = false, // 有一个NetSerialize函数用来在网络复制中序列化
        WithNetDeltaSerializer = false, // 有一个NetDeltaSerialize函数用来在之前NetSerialize的基础上只序列化出差异来，一般用在TArray属性上进行优化
        WithSerializeFromMismatchedTag = false, // 有一个SerializeFromMismatchedTag函数用来处理属性tag未匹配到的属性值，一般是在结构进行升级后，但值还是原来的值，这个时候用来把旧值升级到新结构时使用
        WithStructuredSerializeFromMismatchedTag = false, // SerializeFromMismatchedTag的结构版本
        WithPostScriptConstruct = false,// 有一个PostScriptConstruct函数用在蓝图构造脚本后调用
        WithNetSharedSerialization = false, // 指明结构的NetSerialize函数不需要用到UPackageMap
    };
};
template<class CPPSTRUCT>
struct TStructOpsTypeTraits : public TStructOpsTypeTraitsBase2<CPPSTRUCT>
{
};
```
举个小例子，假如你看到编辑器里某个属性，想在C++里去修改它的值，结果发现它不是public的，甚至有可能连头文件都是private的，这个时候如果对类型系统结构理解不深的人可能就放弃了，但懂的人就知道可以通过这个对象遍历UProperty来查找到这个属性从而修改它。
还有一个例子是如果你做了一个插件，调用了引擎编辑器本身的Details面板属性，但又想隐藏其中的一些字段，这个时候如果不修改引擎往往是难以办到的，但是如果知道了属性面板里的属性其实也都是一个个UProperty来的，这样你就可以通过对象路径获得这个属性，然后开启关闭它的某些Flags来达成效果。这也算是一种常规的Hack方式。
## 《InsideUE4》UObject（十三）类型系统-反射实战
https://zhuanlan.zhihu.com/p/61042237
#### 获取类型对象
如果想获取到程序里定义的所有的class，方便的方法是：
```c++
TArray<UObject*> result;
GetObjectsOfClass(UClass::StaticClass(), result);   //获取所有的class和interface
GetObjectsOfClass(UEnum::StaticClass(), result);   //获取所有的enum
GetObjectsOfClass(UScriptStruct::StaticClass(), result);   //获取所有的struct
```
GetObjectsOfClass是UE4已经写好的一个很方便的方法，可以获取到属于某个UClass*下面的所有对象。因此如果用UClass::StaticClass()本身，就可以获得程序里定义的所有class。值得注意的是，UE4里的接口是有一个配套的UInterface对象来存储元数据信息，它的类型也是用UClass*表示的，所以也会获得interface。根据前文，enum会生成UEnum，struct会生成UScriptStruct，所以把参数换成UEnum::StaticClass()就可以获得所有的UEnum*对象了，UScriptStruct::StaticClass()就是所有的UScriptStruct*了，最后就可以根据这些类型对象来反射获取类型信息了。
而如果要精确的根据一个名字来查找某个类型对象，就可以用UE4里另一个方法：
```c++
template< class T >
inline T* FindObject( UObject* Outer, const TCHAR* Name, bool ExactClass=false )
{
    return (T*)StaticFindObject( T::StaticClass(), Outer, Name, ExactClass );
}
UClass* classObj=FindObject<UClass>(ANY_PACKAGE,"MyClass");   //获得表示MyClass的UClass*
```
#### 遍历字段
在获取到了一个类型对象后，就可以用各种方式去遍历查找内部的字段了。为此，UE4提供了一个方便的迭代器`TFieldIterator<T>`，可以通过它筛选遍历字段。
```c++
const UStruct* structClass; //任何复合类型都可以
//遍历属性
for (TFieldIterator<UProperty> i(structClass); i; ++i)
{
    UProperty* prop=*i;
}
//遍历函数
for (TFieldIterator<UFunction> i(structClass); i; ++i)
{
    UFunction* func=*i;
    //遍历函数的参数
    for (TFieldIterator<UProperty> i(func); i; ++i)
    {
        UProperty* param=*i;
        if( param->PropertyFlags & CPF_ReturnParm ) //这是返回值
        {
        }
    }
}
//遍历接口
const UClass* classObj; //只有UClass才有接口
for (const FImplementedInterface& ii : classObj->Interfaces)
{
    UClass* interfaceClass = ii.Class;
}
//遍历枚举
const UEnum* enumClass;
for (int i = 0; i < enumClass->NumEnums(); ++i)
{
    FName name = enumClass->GetNameByIndex(i);
    int value = enumClass->GetValueByIndex(i);
}
//遍历元数据
#if WITH_METADATA
const UObject* obj;//可以是任何对象，但一般是UField才有值
UMetaData* metaData = obj->GetOutermost()->GetMetaData();
TMap<FName, FString>* keyValues = metaData->GetMapForObject(obj);
if (keyValues != nullptr&&keyValues->Num() > 0)
{
    for (const auto& i : *keyValues)
    {
        FName key=i.Key;
        FString value=i.Value;
    }
}
#endif
//查找属性
UProperty* UStruct::FindPropertyByName(FName InName) const
{
    for (UProperty* Property = PropertyLink; Property != NULL; Property = Property->PropertyLinkNext)
    {
        if (Property->GetFName() == InName)
        {
            return Property;
        }
    }
    return NULL;
}
//查找函数
UFunction* UClass::FindFunctionByName(FName InName, EIncludeSuperFlag::Type IncludeSuper) const;
```
#### 查看继承
```c++
//得到类型对象后，也可以遍历查看它的继承关系。 遍历继承链条：
const UStruct* structClass; //结构和类
TArray<FString> classNames;
classNames.Add(structClass->GetName());
UStruct* superClass = structClass->GetSuperStruct();
while (superClass)
{
    classNames.Add(superClass->GetName());
    superClass = superClass->GetSuperStruct();
}
FString str= FString::Join(classNames, TEXT("->")); //会输出MyClass->UObject
//那反过来，如果想获得一个类下面的所有子类，可以这样：
const UClass* classObj; //结构和类
TArray<UClass*> result;
GetDerivedClasses(classObj, result, false);
//函数原型是
void GetDerivedClasses(UClass* ClassToLookFor, TArray<UClass *>& Results, bool bRecursive);
//那么怎么获取实现了某个接口的所有子类呢？
TArray<UObject*> result;
GetObjectsOfClass(UClass::StaticClass(), result);
TArray<UClass*> classes;
for (UObject* obj : result)
{
    UClass* classObj = Cast<UClass>(obj);
    if (classObj->ImplementsInterface(interfaceClass))//判断实现了某个接口
    {
        classes.Add(classObj);
    }
}
```
#### 获取设置属性值
```c++
template<typename ValueType>
ValueType* UProperty::ContainerPtrToValuePtr(void* ContainerPtr, int32 ArrayIndex = 0) const
{
    return (ValueType*)ContainerVoidPtrToValuePtrInternal(ContainerPtr, ArrayIndex);
}
template<typename ValueType>
ValueType* UProperty::ContainerPtrToValuePtr(UObject* ContainerPtr, int32 ArrayIndex = 0) const
{
    return (ValueType*)ContainerVoidPtrToValuePtrInternal(ContainerPtr, ArrayIndex);
}
void* UProperty::ContainerVoidPtrToValuePtrInternal(void* ContainerPtr, int32 ArrayIndex) const
{
    //check...
    return (uint8*)ContainerPtr + Offset_Internal + ElementSize * ArrayIndex;
}
void* UProperty::ContainerUObjectPtrToValuePtrInternal(UObject* ContainerPtr, int32 ArrayIndex) const
{
    //check...
    return (uint8*)ContainerPtr + Offset_Internal + ElementSize * ArrayIndex;
}
//获取对象或结构里的属性值地址，需要自己转换成具体类型
void* propertyValuePtr = property->ContainerPtrToValuePtr<void*>(object);
//包含对象引用的属性可以获得对象
UObject* subObject = objectProperty->GetObjectPropertyValue_InContainer(object);
//也因为获取到的是存放属性值的指针地址，所以其实也就可以*propertyValuePtr=xxx;方便的设置值了。当然如果是从字符串导入设置进去，UE4也提供了两个方法来导出导入：
//导出值
virtual void ExportTextItem( FString& ValueStr, const void* PropertyValue, const void* DefaultValue, UObject* Parent, int32 PortFlags, UObject* ExportRootScope = NULL ) const;
//使用
FString outPropertyValueString;
property->ExportTextItem(outPropertyValueString, property->ContainerPtrToValuePtr<void*>(object), nullptr, (UObject*)object, PPF_None);
//导入值
const TCHAR* UProperty::ImportText( const TCHAR* Buffer, void* Data, int32 PortFlags, UObject* OwnerObject, FOutputDevice* ErrorText = (FOutputDevice*)GWarn ) const;
//使用
FString valueStr;
prop->ImportText(*valueStr, prop->ContainerPtrToValuePtr<void*>(obj), PPF_None, obj);
```
#### 反射调用函数
```c++
//方法原型
int32 UMyClass::Func(float param1);
UFUNCTION(BlueprintCallable)
int32 InvokeFunction(UObject* obj, FName functionName,float param1)
{
    struct MyClass_Func_Parms   //定义一个结构用来包装参数和返回值，就像在gen.cpp里那样
    {
        float param1;
        int32 ReturnValue;
    };
    UFunction* func = obj->FindFunctionChecked(functionName);
    MyClass_Func_Parms params;
    params.param1=param1;
    obj->ProcessEvent(func, &params);
    return params.ReturnValue;
}
//使用
int r=InvokeFunction(obj,"Func",123.f);
```
ProcessEvent也是UE4里事先定义好的非常方便的函数，内部会自动的处理蓝图VM的问题。当然，更底层的方法也可以是：
```c++
//调用1
obj->ProcessEvent(func, &params);
//调用2
FFrame frame(nullptr, func, &params, nullptr, func->Children);
obj->CallFunction(frame, &params + func->ReturnValueOffset, func);
//调用3
FFrame frame(nullptr, func, &params, nullptr, func->Children);
func->Invoke(obj, frame, &params + func->ReturnValueOffset);
```
#### 运行时修改类型
让我们继续扩宽一下思路，之前已经详细讲解过了各大类型对象的构造过程，最后常常都是到UE4CodeGen_Private里的调用。既然我们已经知道了它运行的逻辑，那我们也可以仿照着来啊！我们也可以在常规的类型系统注册流程执行完之后，在游戏运行的半途过程中，动态的去修改类型甚至注册类型，因为说到底UE4编辑器也就是一个特殊点的游戏而已啊！这种方式有点类似C#的emit的方式，用代码去生成代码然后再编译。这些方式理论上都是可以通的，我来提供一些思路用法，有兴趣的朋友可以自己去实现下，代码贴出来就太长了。
1. 修改UField的MetaData信息，其实可以改变字段在编辑器中的显示信息。MetaData里有哪些字段，可以在ObjectMacros.h中自己查看。
2. 动态修改UField的相应的各种Flags数据，比如PropertyFlags，StructFlags，ClassFlags等，可以达成在编辑器里动态改变其显示行为的效果。
3. 动态添加删除UEnum对象里面的Names字段，就可以动态给enum添加删除枚举项了。
4. 动态地给结构或类添加反射属性字段，就可以在蓝图内创建具有不定字段的结构了。当然前提是在结构里预留好属性存放的内存，这样UProperty的Offset才有值可指向。这么做现在想来好像也不知道能用来干嘛。
5. 同属性一样，其实参照对了流程，也可以动态的给蓝图里暴露函数。有时候这可以达成某种加密保护的奇效。
6. 可以动态的注册新结构，动态的构造出来相应的UScriptStruct其实就可以了。
7. 动态注册新类其实也是可以的，只不过UClass的构造稍微要麻烦点，不过也没麻烦到哪去，有需求了就自然能照着源码里的流程自己实现一个流程出来。
8. 再甚至，其实某种程度上的用代码动态创建蓝图节点，填充蓝图VM指令其实也是可行的。只不过想了想好像一般用不着上这种大手术。
