I tried what you suggested but I get a: "syntax error : missing ';' before identifier 'game'" in the extern HekkusSample game; line.
Even so, is this is a good way (maybe the only way) to access a variable from an outside file? From what i've understand the compiler will not allocate memory for the variable. Which sounds not so good performance wise (since the variable is a huge game object).
Thanks for looking at my problem. I send Conan my zipped project and he's looking at it right now. It seems like a great rescourse for me this forum
