Variables Namespace

Values you set on the dashboard and read while your app runs. Change one without shipping a new build.

The three accessors

// Read three keys you set on the dashboard.
std::string banner = Atlas::Variables::Fetch("update_banner");
bool        debug  = Atlas::Variables::FetchBool("debug_enabled");
int         cap    = Atlas::Variables::FetchInt("max_users");
 
if (!banner.empty()) {
    ui::ShowBanner(banner);
}
