这样,Character 所拥有的技能在类的成员变量表示就不能是TArray<TSubclassOf<UAbilityOwned>> AbilitesOwned;(不能是 UClass),而是TArray<TObjectPtr<UAbilityOwned>> AbilitesOwned;(UObject 的形式),通过为 Object 赋值成员变量来做到函数参数的传递。就像上述代码中的 1TObjectPtr<UAbilityOwned> NewAbilityCDO =...

let you avoid allocating an entire TArray just to return a variable number of values. Easier for you to write, easier for the compiler to optimize, you only need O(1) storage instead of O(N) for N items, what’s not to like? List of features The following links will get you to ...
