Error C3867 in C++
提问by Xturbed1442
My code was working fine until I reloaded the program a few hours later. Now I get these this error:
我的代码运行良好，直到几个小时后我重新加载了程序。现在我得到这些错误：
error C3867: 'player::getxPos': function call missing argument list; use '&player::getxPos' to create a pointer to member
error C3867: 'player::getyPos': function call missing argument list; use '&player::getyPos' to create a pointer to member
错误 C3867：“player::getxPos”：函数调用缺少参数列表；使用 '&player::getxPos' 创建指向成员的指针
错误 C3867：“player::getyPos”：函数调用缺少参数列表；使用 '&player::getyPos' 创建指向成员的指针
This is the code in question:
这是有问题的代码：
if (P->shoot())
{
shotVector.push_back(shot());
eS = shotVector.size();
shotVector[eS-1].initShot(
P->getxPos, // C3867
P->getyPos // C3867
);
}
I'm trying to call two functions from a class called player and these two functions look like this:
我正在尝试从名为 player 的类中调用两个函数，这两个函数如下所示：
int player::getxPos(){
return xPos;
};
int player::getyPos(){
return yPos;
};
What's being done is that I'm trying to ask for the players position and then use that to decide where to shoot from.
正在做的是我试图询问球员的位置，然后用它来决定从哪里射门。

shotVector[eS-1].initShot(P->getxPos, P->getyPos);- you are trying to call the getxPos()and getyPos()members without ().
shotVector[eS-1].initShot(P->getxPos, P->getyPos);-你试图调用getxPos()和getyPos()成员没有()。
Use getxPos()and getyPos().
使用getxPos()和getyPos()。

You forgot the parenthesis, which tell the compiler that you want a method call:
你忘记了括号，它告诉编译器你想要一个方法调用：
P->getxPos
vs
对比
P->getxPos()
If you instead used &P->getxPos, that would give you a pointer to the member function itself.
如果您改为使用&P->getxPos，那会给您一个指向成员函数本身的指针。

shotVector[eS-1].initShot(P->getxPos(), P->getyPos());
