I have a class that calls another class. but when i call it it says it''s not there.
Particle particle = new Particle();
for example. it says it''s not there but it is definately there and compiled properly.
I use Microsoft visual studio c++ 6.0. do i have to tell it where to find the file or something????

another question. I want to program a particle engine. Nehe''s tutorial is good but i don''t think the data structure is very reusable. Does anyone have any good ideas on what kindof data structure I would need. I think a good oo approach with vectors(the push pop ones. not the xyz ones) would work good. So i can just say, a group of particles there. and add another group with totally different properties somewhere else very easily.

   class TParticleBase{  protected:    TVector3f* Particles;    int NumParticles;    DWORD Type;  public:    TParticleBase() { };    virtual void Render() { };    virtual void Iterate() { };} class TParticleFire : public TParticleBase{  private:    TColor ColorFire;    TColor ColorFlame;    float Falloff;    TVector3f Direction;    /*any other variables you might want*/  public:    void Render()      {      //draw your fancy fire here      }    void Iterate()      {      //claculate new particle positions (based on time elapsed, for instance)      }}class TParticleHalo : public TPasrticleBase{//bla-bla - mostly same as TParticleFire}void WinMain(...){TParticleBase* Flame = new TParticleFire;TParticleBase* Halo = new TParticleHalo;while(true)  {  glTranslate(pos_of_flame);  Flame->Iterate();  Flame->Render();  glTranslate(pos_of_halo);  Halo->Iterate();  Halo->Render();  } }
