Questions regarding Vector Array of Structs

Question

I made a post about this yesterday, but it is a fairly different question. Not sure if I should make a new question or just reply to the old one but here goes.

Basically I am setting up my vector array of structs as follows..

class Debugger : public Ogre::SimpleRenderable
{
    struct DebugVertex
    {
        Ogre::Vector3 v;
        unsigned int color;
    };

    typedef std::vector<DebugVertex> Buffer;

protected:

    Buffer              mLineBuffer;

The problem is occuring in the code for example...

mLineBuffer.reserve(128); reports it is not a member of Debugger::DebugVertex. This holds true with all vector operations such as reserve, empty, ptr, size, etc. They all exist but it is looking for them in the struct. How am I supposed to access these?

Answer 1

What's the exact compiler error? My guess is that DebugVertex does not conform to the interface required for inclusion in STL containers like std::vector, possibly because Ogre::Vector3 needs work.

Can you include the declaration for Ogre::Vector3?

Answer 2

Your typedef using a private struct, any code outside the Debugger class trying to use it will not compile.

std::vector is not part of your class...

Either make std::vector<DebugVertex> a friend class (didn't test, have to check) or simply make your structure public.
