曠野的呼聲

好貼，轉了。

還是剛才那句話，沒源碼能讓你發瘋。
無論是kismet還是matinee還是材質編輯器，都非常牛叉。其實還有更多的資料沒有公用許可，需要花美刀去購買的。其實Epic這么干無非是先讓你嘗鮮，然后再勾引你去買，這樣的話他的目的就達到了，就像微軟并沒有真正意義上的變態的打擊盜版一樣。。。55555555555.。。樓主，以后多聯系。。。不過很少上cppblog.祝你愉快。

光是UDK用起來還是沒有有代碼好，至少有代碼上手比較快。當然有代碼也有悲劇的時候，特別是遇到有的時候升級造成的難以察覺的Bug。我就遇到過Content瀏覽器的一個Bug，哎，悲劇~~

郁悶的是UDK都免費了，nFringe卻收費了，郁悶啊，那該死的UDE也太難用了，還是VS用著爽。可惜可惜。

我是樓上。

悲劇啊，最新版的nfringe貌似收費了啊，郁悶。要在VS里面調試的話，還得用老版本，還好我有老版本可以用，要不然就徹底悲劇了。

我又回來了。
FStringNoInit
FName...
如果樓主能分享一下autoexp.dat就好了，哈哈。

謝謝樓主，哈哈。

這個方法不佳。。。
誰有沒有更好的方法提出來哈，呵呵。

6.2. Requirements for Call Wrapper Types
TR1 defines some additional terms that are used to describe requirements for callable types.

First, INVOKE(fn, t1, t2, ..., tN) describes the effect of calling a callable object fn with the arguments t1, t2, ..., tN. Naturally, the effect depends on the type of the callable object. INVOKE is defined as follows:

(t1.*fn)(t2, ..., tN) when fn is a pointer to a member function of a class T and t1 is an object of type T or a reference to an object of type T or a reference to an object of a type derived from T

((*t1).*fn)(t2, ..., tN) when fn is a pointer to a member function of a class T and t1 is not one of the types described in the previous item

t1.*fn when fn is a pointer to member data of a class T and t1 is an object of type T or a reference to an object of type T or a reference to an object of a type derived from T

(*t1).*fn when fn is a pointer to member data of a class T and t1 is not one of the types described in the previous item

fn(t1, t2, ..., tN) in all other cases

What this amounts to is that when the callable object is an ordinary function or a pointer to an ordinary function, INVOKE means to call that function, passing the rest of the arguments to the function call. When the callable object is a pointer to member, the next argument refers to the object that it should be applied to. That argument is the object itself, a reference to the object, a pointer to the object, or some kind of smart pointer that points to the object. The rest of the arguments are passed to the function call.

Second, INVOKE_R(fn, t1, t2, ..., tN, Ret) describes the effect of calling a callable object fn with an explicit return type, Ret. It is defined as INVOKE(fn, t1, t2, ..., tN) implicitly converted to Ret.[5]

[5] In the TR, this metafunction is named INVOKE; although I'm one of the people responsible for this name overloading, I've now concluded that it's too clever and shouldn't be used.

Third, some call wrapper types have a weak result type; this means that they have a nested member named result_type that names a type determined from the call wrapper's target type, Ty.

If Ty is a function, reference to function, pointer to function, or pointer to member function, result_type is a synonym for the return type of Ty

If Ty is a class type with a member type named result_type, result_type is a synonym for Ty::result_type

Otherwise, result_type is not defined[6]

[6] That is, not defined as a consequence of having a weak result type. Some call wrapper types have a weak result type in certain circumstances, have a specific type named result_type

A few examples will help clarify what this rather dense text means:

struct base {
void f();
int g(double);
int h(double,double);
};
struct derived : base {
};

base b;
derived d;
base& br = d;



With these definitions, rule 1 gives the following meanings to these uses of INVOKE .

Phrase
Meaning

INVOKE (&base::f, b)
(b.*f)()

INVOKE (&base::g, d, 1.0)
(d.*f)(1.0)

INVOKE (&base::h, br, 1.0, 2.0)
(br.*f)(1.0, 2.0)





That is, the pointer to member function is called on the object or reference named by t1:

derived *dp = new derived;
base *bp = dp;
shared_ptr<base> sp(bp);



With these additional definitions, rule 2 gives the following meanings to these uses of ( INVOKE):

Phrase
Meaning

INVOKE (&base::f, bp)
((*bp).*f)()

INVOKE (&base::g, dp, 1.0)
((*dp).*f)(1.0)

INVOKE (&base::h, sp, 1.0, 2.0)
((*sp).*f)(1.0, 2.0)





That is, the pointer to member function is called on the object that the argument t1 points to. Since it uniformly dereferences that argument, the rule works for any type whose operator* returns a reference to a suitable object. In particular, the rule works for shared_ptr objects.

Rules 3 and 4 give similar meanings to INVOKE uses that apply pointers to member data:

void func(base&);
struct fun_obj {
void operator()() const;
bool operator()(int) const;
};
fun_obj obj;



With these additional definitions, rule 5 gives the following meanings to these uses of INVOKE:

Phrase
Meaning

INVOKE (func, d)
func(d)

INVOKE (obj)
obj()

INVOKE (obj, 3)
obj(3)

@金慶
呵呵，我是說這個名字怎么這么面熟呢？
有時間把asio翻譯翻譯吧，哈哈。。。
我英語不是很好，簡單點的還成，稍微復雜點的句子就迷糊了，呵呵。
asio東拼西湊的看了一些資料，由于沒有完整的理解到所有的東西，所以用的時候總是畏首畏尾的，呵呵。

樓主，學習C++和Boost的時候看到了您的很多資料，非常感謝您的無私奉獻！
現在大學要畢業了，以后可能沒這么多時間像現在一樣學習了，呵呵。
感謝樓主!感謝金慶。
您是google的boost翻譯組的嗎？我看到了您的一些貢獻。

《實時計算機圖形學》第三版都出了，強烈期待中文翻譯版本啊，英文我瞅不懂。

厲害啊！！！！

樓主好！
