Your <code>Fire</code> class doesn't have an assignment operator, or it is not accessible.

But the <code>vector::erase()</code> implementation must need it because, as <a href="http://www.cplusplus.com/reference/vector/vector/erase/" rel="nofollow">http://www.cplusplus.com/reference/vector/vector/erase/</a> points out, erasing elements might cause elements to be relocated.

blocks|key|1729742|text|我认为您的基本问题是，您试图设计一个单独的类，它执行两种不同的操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1729743|包含一个火灾向量|unordered-list-item|1729744|实现火灾的行为|1729745|1729746|1729747|一个更好的设计是有两个独立的类。|1729748|1实现火灾行为的类|1729749|2一个类，它包含一个火灾向量，并实现方法，如update，以迭代该向量中包含的火，调用fire方法。|1729750|看起来是这样的：|1729751|class+Fire+{
++//+implements+individual+method+on+an+instance+of+fire,+such+as++liefetime
};

class+FireContainer+{
++//+implements+method+to+deal+with+all+the+fires,+such+as+update
++std::+vector<+Fire+>+myFires;

};|code-block|syntax|javascript|1729752|但是，如果您想继续使用单个类，并且将火灾向量作为全局(通常认为是不好的做法)，那么方法更新不应该是Fire类的成员，而应该是一个免费的函数。|1729753|entityMap^0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Z|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|10|8|@]|9|@]|A|$]]|$1|E|3|F|5|D|7|11|8|@]|9|@]|A|$]]|$1|G|3|-4|5|6|7|12|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|13|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|14|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|15|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|16|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|17|8|@]|9|@]|A|$]]|$1|Q|3|R|5|S|7|18|8|@]|9|@]|A|$T|U]]|$1|V|3|W|5|6|7|19|8|@]|9|@]|A|$]]|$1|X|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|Y|$]]

I think that your basic problem is that you have tried to design a single class which does two different things:

<ul>
<li>Contains a vector of fires</li>
<li>Implements the behaviour of a fire</li>
</ul>

A much better design is to have two separate classes

1 A class to implement the behaviour of a fire

2 A class which contains a vector of fires, and implements methods, such as update, to iterate over the fires contained in the vector, invoking the fire methods.

It would look like this:

<pre><code>class Fire {
 // implements individual method on an instance of fire, such as liefetime
};

class FireContainer {
 // implements method to deal with all the fires, such as update
 std:: vector&lt; Fire &gt; myFires;

};
</code></pre>

However, if you want to continue with a single class, and have the vector of fires as global ( usually considered bad practice ) then the method update should not be a member of the Fire class, but a free function.

My vector.erase() function gives me an error -> "error C2582: 'operator =' function is unavailable in 'Fire'

here is the code and the vector is declared in the header file.

any help is appreciated.

<pre><code>//header
std::vector&lt;Fire&gt; _fires;

//cpp
void Fire::update()
{
 for (unsigned int i = 0; i &lt; _fires.size(); i++)
 {

 _fires[i].lifeTimer(); // updates the lifetime for all objects

 if (_fires[i]._lifetime &gt;= 200)
 {
 _fires.erase(_fires.begin() + i); //erase not working
 }
 }
}
</code></pre>
