i have a pure virtual base class for entities, called cObject, with basic methods: update( float timeDelta ); render(); setPosition( int x, int y ); ////etc i derive off of this class for sprites, animations, particle systems.. all renderable objects. the only problem is.... the particle system one doesnt work. i add them to objectLists that old cObjects. and if i write to my log file every time cParticle::render() is called... i check the log and its not there. so when i add this particle to the list and i call objectList->render() (Which just calls render for all of the objects ) it doesnt seem to be called the cParticle's render method. any clues why?

actually i did overload the render method, but i found the problem. i have an isActive() method that tells the object list if the sprite should be deleted or not. my logic for this was flawed with the cParticle class (i was doing it based on particle count, not lifetime ) but now it works fine. thanks anyway.
