i CompleteStack.Num(); i) {ClassKindLoadStack.Remove(CompleteStack[i]);delete CompleteStack[i];} }测试批量加载多个同类 UClass 资源 接下来是验证环节我们打算让多个 Actor 生成在场景中并且为了让它们不会挤到一块所以每次生成的时候将位置偏移一点。 WealthCallObject.h public:// 回调函数UFUNCTION()void LoadKindClass(TArrayFName BackNames, TArrayUClass* BackWealths);public:// 生成的偏移量UPROPERTY(EditAnywhere)float OffsetValue;WealthCallObject.cpp void UWealthCallObject::DDLoading() {// 测试完毕后记得注释掉LoadClassWealthKind(ViewActor, LoadKindClass); }void UWealthCallObject::LoadKindClass(TArrayFName BackNames, TArrayUClass* BackWealths) {for (int i 0; i BackWealths.Num(); i) {DDH::Debug() BackNames[i] DDH::Endl();GetDDWorld()-SpawnActorAActor(BackWealths[i], ViewTrans.GetLocation() FVector(OffsetValue * i, 0.f, 0.f), FQuat::Identity.Rotator());} }编译后在 Blueprint 文件夹下创建一个 ViewActor 文件夹将 ViewActor1 放进去并复制两个分别取名为 ViewActor2 和 ViewActor3。给它俩换一下网格体模型。 给 PlayerData 里再配置两个 Class 资源数据 打开 WealthCallObject 的蓝图设置 Offset Value 为 150。 运行游戏可见左上角输出了 3 个 Class 资源的名字场景内也出现了它们的实例。 在第一次运行后在 Deal{xxx}LoadStack() 方法里会给加载节点里的 UObject* / UClass* 赋值它们就不为空了也就不会进行异步加载为了让它每次都像第一次运行那样为了方便测试异步加载无误我们要修改一下代码让它在编辑器运行时每次都清空 WealthObject 和 WealthClass。这样就以后打包完游戏就不会自动清空。 DDWealth.cpp void UDDWealth::WealthBeginPlay() {for (int i 0; i WealthData.Num(); i) {// … 省略#if WITH_EDITOR // 循环设置 WealthObject 和 WealthClass 为空目的在于每次从编辑器启动游戏时资源 Asset 的状态都重置for (int j 0; j WealthData[i]-ObjectWealthData.Num(); j)WealthData[i]-ObjectWealthData[j].WealthObject NULL;for (int j 0; j WealthData[i]-ClassWealthData.Num(); j)WealthData[i]-ClassWealthData[j].WealthClass NULL; #endif} }47. 创建单个资源对象 我们先前写的逻辑都是加载资源然后将其返回给请求者接下来我们打算实现加载 UClass 资源并创建对象后将对象返回给请求者。 下图截取自梁迪老师的 DataDriven 文档 创建多个对象的方法里每帧都会创建一个对象创建足够数量的对象后才会将所有的对象返回给请求对象。 这节课我们先实现创建单个资源对象的功能。 DDWealth.h public:// 创建一个对象实例void BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName ObjectName, FName FunName, FTransform SpawnTransform);protected:// 生成三种资源对象的反射回调函数DDOBJFUNC_TWO(BackObject, FName, BackName, UObject, BackObject);DDOBJFUNC_TWO(BackActor, FName, BackName, AActor, BackActor);DDOBJFUNC_TWO(BackWidget, FName, BackName, UUserWidget, BackWidget);DDWealth.cpp // 给 UClass 加载节点补充另外的内容以便支持对象创建 struct ClassSingleLoadNode {TSharedPtrFStreamableHandle WealthHandle;FClassWealthEntry WealthEntry;FName ObjectName;FName FunName;// 生成位置FTransform SpawnTransform;// 是否只加载 UClass 资源bool IsLoadClass;ClassSingleLoadNode(TSharedPtrFStreamableHandle InWealthHandle, FClassWealthEntry* InWealthEntry, FName InObjectName, FName InFunName){WealthHandle InWealthHandle;WealthEntry InWealthEntry;ObjectName InObjectName;FunName InFunName;IsLoadClass true; // 添加}// 另一个构造函数ClassSingleLoadNode(TSharedPtrFStreamableHandle InWealthHandle, FClassWealthEntry* InWealthEntry, FName InObjectName, FName InFunName, FTransform InSpawnTransform){WealthHandle InWealthHandle;WealthEntry InWealthEntry;ObjectName InObjectName;FunName InFunName;SpawnTransform InSpawnTransform;IsLoadClass false;} };// 给处理方法增加判断是仅仅加载资源还是创建对象 void UDDWealth::DealClassSingleLoadStack() {TArrayClassSingleLoadNode* CompleteStack;for (int i 0;

i CompleteStack.Num(); i) {ClassSingleLoadStack.Remove(CompleteStack[i]);delete CompleteStack[i];} }void UDDWealth::BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName ObjectName, FName FunName, FTransform SpawnTransform) {// 获取对应的资源结构体FClassWealthEntry* WealthEntry GetClassSingleEntry(WealthName);// 如果为空if (!WealthEntry) {DDH::Debug() ObjectName Get Null Wealth : WealthName DDH::Endl();return;}// 如果资源不可用if (!WealthEntry-WealthPtr.ToSoftObjectPath().IsValid()) {DDH::Debug() ObjectName Get UnValid Wealth : WealthName DDH::Endl();return;}// 资源类型是否匹配if (WealthEntry-WealthType ! WealthType) {DDH::Debug() ObjectName Get Error Type : DDH::Endl();return;}// 如果资源已经加载if (WealthEntry-WealthClass) {// 根据类型来执行不同生成逻辑并且传递对象到请求者if (WealthType EWealthType::Object) {UObject* InstObject NewObjectUObject(this, WealthEntry-WealthClass);InstObject-AddToRoot();// 传递对象到请求者BackObject(ModuleIndex, ObjectName, FunName, WealthName, InstObject);}else if (WealthType EWealthType::Actor) {AActor* InstActor GetDDWorld()-SpawnActorAActor(WealthEntry-WealthClass, SpawnTransform);BackActor(ModuleIndex, ObjectName, FunName, WealthName, InstActor);}else if (WealthType EWealthType::Widget) {UUserWidget* InstWidget CreateWidgetUUserWidget(GetDDWorld(), WealthEntry-WealthClass);// 避免回收GCWidgetGroup.Push(InstWidget);BackWidget(ModuleIndex, ObjectName, FunName, WealthName, InstWidget);}}else {// 异步加载获取加载句柄TSharedPtrFStreamableHandle WealthHandle WealthLoader.RequestAsyncLoad(WealthEntry-WealthPtr.ToSoftObjectPath());// 创建新加载节点ClassSingleLoadStack.Push(new ClassSingleLoadNode(WealthHandle, WealthEntry, ObjectName, FunName, SpawnTransform));} }补全 DDWealth – DDModule – DDOO – 对象 的调用链。 DDModule.h public: // 创建一个对象实例void BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName ObjectName, FName FunName, FTransform SpawnTransform);DDModule.cpp void UDDModule::BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName ObjectName, FName FunName, FTransform SpawnTransform) {Wealth-BuildSingleClassWealth(WealthType, WealthName, ObjectName, FunName, SpawnTransform); }DDOO 有些不一样它需要额外判断是否需要传入生成位置这是专门为 Actor 准备的。 DDOO.h protected:// 创建一个对象实例// 给 Object 和 Widget 用的void BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName FunName);// 给 Actor 用的void BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName FunName, FTransform SpawnTransform);DDOO.cpp void IDDOO::BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName FunName) {IModule-BuildSingleClassWealth(WealthType, WealthName, GetObjectName(), FunName, FTransform::Identity); }void IDDOO::BuildSingleClassWealth(EWealthType WealthType, FName WealthName, FName FunName, FTransform SpawnTransform) {IModule-BuildSingleClassWealth(WealthType, WealthName, GetObjectName(), FunName, SpawnTransform); }测试加载并创建单个 UClass 资源对象 我们打算只测试创建一个 Actor 资源对象并且让它一直旋转。 WealthCallObject.h public:virtual void DDTick(float DeltaSeconds) override;// 回调方法UFUNCTION()void BuildActor(FName BackName, AActor* BackActor);public:// 保存返回的 ActorAActor* SingleActor;WealthCallObject.cpp void UWealthCallObject::DDLoading() {Super::DDLoading();IsAllowTickEvent true; // 实际上开启帧函数的bool值这个最好放在 DDInit()// … 省略// 测试完毕后记得注释掉BuildSingleClassWealth(EWealthType::Actor, ViewActor1, BuildActor, ViewTrans); }void UWealthCallObject::DDTick(float DeltaSeconds) {Super::DDTick(DeltaSeconds);if (SingleActor) {SingleActor-AddActorWorldRotation(FRotator(1.f, 0.f, 0.f));} }void UWealthCallObject::BuildActor(FName BackName, AActor* BackActor) {DDH::Debug() BackName DDH::Endl();SingleActor BackActor; }编译后运行游戏可以看见左上角输出了 ViewActor1场景中生成了 ViewActor1并且它一直在旋转。说明加载并创建 UClass 对象的逻辑写好了。 顺便打开 PlayerData 将 AutoActorData 下的两个对象去掉免得在场景里占位置。

1. 创建同类资源对象 接下来实现创建多个同种类名WealthKind的资源对象实例后返回给申请者。 DDWealth.h 里的反射回调函数的声明宏调整一下原本第一个参数的命名加一个 Single避免与最后一个参数重名。并且 .cpp 里对应的调用语句也要跟着修改。 DDWealth.h public:// 创建同资源种类名的对象实例同种类名下的每个资源链接创建一个对象实例void BuildKindClassWealth(EWealthType WealthType, FName WealthKind, FName ObjectName, FName FunName, TArrayFTransform SpawnTransforms);protected:// 给之前的生成单个对象的反射回调函数函数名后添加 “Single”DDOBJFUNC_TWO(BackObjectSingle, FName, BackName, UObject, BackObject);// 添加同种类 Object 的反射回调函数DDOBJFUNC_TWO(BackObjectKind, TArrayFName, BackNames, TArrayUObject, BackObjects);DDOBJFUNC_TWO(BackActorSingle, FName, BackName, AActor, BackActor);// 添加同种类 Actor 的反射回调函数DDOBJFUNC_TWO(BackActorKind, TArrayFName, BackNames, TArrayAActor, BackActors);DDOBJFUNC_TWO(BackWidgetSingle, FName, BackName, UUserWidget, BackWidget);// 添加同种类 Widget 的反射回调函数DDOBJFUNC_TWO(BackWidgetKind, TArrayFName, BackNames, TArrayUUserWidget, BackWidgets);DDWealth.cpp struct ClassKindLoadNode {TSharedPtrFStreamableHandle WealthHandle;TArrayFClassWealthEntry* UnLoadWealthEntry;TArrayFClassWealthEntry* LoadWealthEntry;FName ObjectName;FName FunName;// 多个生成位置TArrayFTransform SpawnTransforms;// 是否只加载 Classbool IsLoadClass;// 保存生成的对象与名字TArrayFName NameGroup;TArrayUObject* ObjectGroup;TArrayAActor* ActorGroup;TArrayUUserWidget* WidgetGroup;ClassKindLoadNode(TSharedPtrFStreamableHandle InWealthHandle, TArrayFClassWealthEntry* InUnLoadWealthEntry, TArrayFClassWealthEntry* InLoadWealthEntry, FName InObjectName, FName InFunName){WealthHandle InWealthHandle;UnLoadWealthEntry InUnLoadWealthEntry;LoadWealthEntry InLoadWealthEntry;ObjectName InObjectName;FunName InFunName;IsLoadClass true;
