Executing Delegates Dynamic Delegates Dynamicdelegatescan be serialized, their functions can be found by name, and they are slower than regular delegates.

DECLARE_DYNAMIC_DELEGATE_RetVal_OneParam( ReturnValueType, DelegateName, Param1Type, Param1Name ) 例如: DECLARE_DELEGATE_RetVal_OneParam(bool, FIsMontagePlayingExceptSlots, const TArray<FName>&); 补充点: 多播委托与单播委托都支持多参数传入,引擎支持最多9个参数。 委托的命名开头必须为F,否则会编译报...
在UE4中,委托参数主要分为两种类型:动态多播委托(Dynamic Multicast Delegate)和动态单播委托(Dynamic Delegate)。 1. 动态多播委托 动态多播委托允许多个函数同时注册到同一个委托对象上,并按照注册顺序进行调用。当委托对象触发时,所有注册的函数都会被依次调用。这种委托参数适用于需要同时通知多个对象的场景,比如游戏中...

非dynamic delegate不支持。issus/128 不可以直接导出类的static成员,但可以为它封装一个static方法。issus/22 不支持绑定lua脚本到对象实例,NewObject指定的脚本是绑定到UCLASS的。issus/134 调用父类函数 在UEC++中,当我们重写了一个父类的虚函数,可以通过调用Super::来指定调用父类实现,但是在Lua中不同。
