瞄见UHT(Unreal Header Tool)的时候,我想到了Qt的Moc(Meta Object Compiler),工作流程就是扫描代码头文件,得到一些信息,然后生成新的代码文件添加到构建目标中,使用它来实现UE的代码反射,而通过反射,可以实现基于类型的控件,基于对象的面板,还能自行组织反射数据,从而实现像蓝图这样的可视化编程脚本。
Objects Instead of Pointers 任何声明为UObject 类型的变量,自动变成 object 的引用。没有指针。没有->arrow,只有. dots。( Cpp 的引用,本质上是不能为空的指针。) 不用特意将 property 声明为UPROPERTY()以防止被垃圾回收。脚本的所有 object references 都自动插入 GC 。 void TeleportActorToOtherActor(AActor...
Monoscopic far field rendering can provide a big performance boost by only rendering distant objects once!Stereo divergence decreases as objects are rendered farther from the camera. At a certain distance, the stereo rendering of distant objects is indistinguishable from a regular monoscopic rendering. ...
This is a much lower-level construct than Actor, but still has features that you will expect from a Unreal class, such as Reflection and Serialization. Object is a very basic class we use when we need to define a new type that just does not fit the mold of an Actor. For...

Each menu isconstructedvia theConstruct()function, which adds all of the necessary menu items, including sub-items, and attaches delegates to them where necessary. This is done using the helper methods -AddMenuItem(),AddMenuItemSP(), etc. - defined in theMenuHelpernamespace in theSPlatformer...
The element type is the type of the objects that will be stored in the array.TArrayis what is called a homogenous container, meaning that all of its elements are strictly the same type; you cannot store elements of different types in a singleTArray. ...
CesiumFeatureTexturePropertyhandled property values using specialized structs namedCesiumIntegerColorandCesiumFloatColor, which held the channel values of a pixel from the property’s texture. Developers would have to determine the property's type, then manually construct the correct metadata value from ...
Start withConstruct Json Objectthen set any desired fields. In this instance we wanted to make the JSON{“myString”:“Hello”}so we usedSet String Fieldand then auto-convert the object into a message. Complex Json By combining arrays and objects you can form almost any data type, nest aw...
