C++ Class Access Management

I'm developing a game using OpenGL. I have a Game class that contains all the environment variables (by environment, I mean things like gravity or tile sets). There's only one Game object. I also have another class called Entity, which contains properties to display objects on the screen.

I'm finding myself needing access to more and more Game variables in my Entity class. At the moment i'm just using parameters to pass data into each function, but I'm considering just passing a pointer to the Game class? Is there anything wrong with that? Is there a better way?

I think this is good practice. It is good idea to replace a group of parameters with a parameter object.

Just make sure that Game remains cohesive. The variables contained within Game should be related.

Make Entity a Friend of the Game class.

Please see

Note: If this is ever done in C#, there isn't a friend keyword or exact equivalent.
