顺便说一下,引擎的 Blueprint Nativization 功能就是用来避免这种开销。如果启用了蓝图本地化,那么脚本编译器不会生成脚本字节码,而是会吐出 C++ 源代码,该源代码可以直接编译为机器代码;生成的代码不具备可读性,也无法编辑: void AWeapon_C__pf2513711887::bpf__RunWeaponTrace__pf(FTransform bpp__MuzzleTransfor...
直接的蓝图通信(Direct blueprint communication)。 强制转换(casting):允许访问不同蓝图(强制转换蓝图)的特定函数和变量。 蓝图接口(Blueprint Interface):定义一组可由多个蓝图实现的函数。它们提供了在不同对象之间建立公共通信协议的方法。 事件分发器(Event Dispatcher):允许蓝图触发其他蓝图可以侦听和响应的事件。 ...
virtual void PostEditChangeProperty(FPropertyChangedEvent& PropertyChangedEvent) override; 這個函數將在每次變數在editor內被修改時呼叫 函數最後要加 Super:: PostEditChangeProperty(PropertyChangedEvent); 可以用下面的code來判斷是哪個成員被改動 FName PropertyName = (PropertyChangedEvent.Property != nullptr) ?

There are a few options for each UE version that change the internal structs of the Engine (WITH_CASE_PRESERVING_NAME, UE_BLUEPRINT_EVENTGRAPH_FASTCALLS, ..., all found under Engine/Userdefined/UEdefinitions.h). Make sure to know them! Keep in mind that some games (e.g Fortnite or ...
