1. DECLARE_DYNAMIC_DELEGATE_OneParam 代理会回传一个float给绑定的参数,2.TimeLine.AddInterpFloat(CurveFloat, TimeLineDelegate);可将曲线与时间轴绑定,从而回传曲线在当前时间的值给绑定的函数。也可以不同曲线不同绑定混合再一起组合不同的功能。3. TimeLine.TickTi
执行代理方法通常涉及宏FUNC_DECLARE_DYNAMIC_DELEGATE，该宏接收多个参数，如弱指针类型、代理名、执行函数接口、参数类型列表、真正传给绑定函数的参数等。这些参数在执行函数接口中整合，实现动态代理的执行。动态单播代理的父类TBaseDynamicDelegate内部定义了TMethodPtrResolver，用于处理代理的绑定。__Internal...
