Programming style from "Game Coding Complete"
<p>I have recently read Mike McShaffry's <a href="http://rads.stackoverflow.com/amzn/click/1584506806" rel="nofollow">Game Coding Complete</a> and noticed the code style I haven't seen elsewhere yet. The more important things I noticed were the names of base classes defining interfaces starting with an I like <code>IActor</code>, protected member variables' names starting with m_ like <code>m_Type</code> and names of virtual methods like <code>VSetId()</code>. To show a bigger, more readable example:</p>

<pre><code>class BaseActor : public IActor 
{ 
    friend class BaseGameLogic;
protected: ActorId m_id; 
    Mat4×4 m_Mat; 
    int m_Type; 
    shared_ptr &lt;ActorParams&gt; m_Params; 
    virtual void VSetID(ActorId id) { m_id = id; } 
    virtual void VSetMat(const Mat4×4 &amp;newMat) { m_Mat = newMat; } 
public: 
    BaseActor(Mat4×4 mat, int type, shared_ptr&lt;ActorParams&gt; params) 
        { m_Mat=mat; m_Type=type; m_Params=params; } 
    /* more code here */
};
</code></pre>

<p>I pretty much like this style: it seems justified and looks like it helps increase the overall readability of the code. <strong>The question is:</strong> Is it a more-or-less established standard? Is there any more to it than the things I mentioned?</p>
