Hey so I was following this guide on how to make a frame independent game loop, but it made my game loop complex enough to warrant it's own file, pretty much I made a new file and have the game loop logic stored in there and I can start the game loop by passing in some functions to it:
void GameLoop::start(
double update_rate_hz,
const std::function<void(double)>& fixed_timestep_update_func,
const std::function<void()>& non_rate_limited_update_func,
const std::function<int()>& termination_condition_func
) {
(you can think of fixed_timestep_update_func as your physics update call, non_rate_limited_updated_func your render and termination_condition_func as the condition to the while/game loop stopping)
In my main file, I am trying to avoid using global state and I'm just passing things in to certain functions that need them. For example in the past I had
void render(Character character, Model map, Hud hud) { ... }
But due to this refactor I had to make those 3 parameters global because my game loop forces it's signature to be const std::function<void()>& non_rate_limited_update_func and it had to be like this because the game loop doesn't have access to character, map, hud because I wanted that not to be of it's concern.
If I want to not have globals how would I get myself out of this pickle?
