Vector is not a Template?
提问by OmniOwl
I am currently trying to follow a tutorial on making a simple 2D tile engine for top-down RPGs. For some reason though I get the intellisense error
我目前正在尝试学习为自上而下的 RPG 制作简单 2D 磁贴引擎的教程。出于某种原因，虽然我收到了智能感知错误
vector is not a template
vector is not a template
The word "vector" is underlined with red. Why does this not work? Why is it telling me that it's a template, and why does the mean the program won't work?
“矢量”一词用红色下划线标出。为什么这不起作用？为什么它告诉我它是一个模板，为什么这意味着程序不起作用？
#ifndef _IMAGEMANAGER_H
#define _IMAGEMANAGER_H
#include <vector>
#include <SFML\Graphics.hpp>
class ImageManager
{
private:
vector<sf::Texture> textureList;
public:
ImageManager();
~ImageManager();
void AddTexture(sf::Texture& texture);
sf::Texture& GetTexture(int index);
};
#endif
Errors I get (no doubt some of these spawn from the error of this part above):
我得到的错误（毫无疑问，其中一些是从上面这部分的错误中产生的）：

回答by 0x499602D2
vectoris from the stdnamespace, so you must use std::to specify:
vector来自std命名空间，因此您必须使用std::来指定：
std::vector<sf::Texture> textureList;
Or you can use a usingstatement:
或者你可以使用一个using语句：
using std::vector;
vector<sf::Texture> textureList;
回答by Shafik Yaghmour
Since I don't see any usingstatements in your code sample, I am pretty sure you need to add std::to your vectordeclaration, like so:
由于我using在您的代码示例中没有看到任何语句，我很确定您需要添加std::到您的vector声明中，如下所示：
std::vector<sf::Texture> textureList;
