#define SHIT_API
定义 Core.h:14
Shit::Game::IsPaused
static bool IsPaused()
是否处于暂停状态
定义 Game.h:31
Shit::Game::operator=
Game & operator=(Game &&)=delete
Shit::Game::run
void run()
启动主循环（阻塞直至窗口关闭）
Shit::Game::operator=
Game & operator=(const Game &)=delete
Shit::Game::Game
Game(const Game &)=delete
Shit::Game::SetPaused
static void SetPaused(bool paused)
全局暂停（冻结 Behavior/物理，UI 叠层照常）
定义 Game.h:30
Shit::Game::Destroy
static void Destroy()
反初始化，按依赖逆序清理子系统（init 部分失败时也能安全调用）
定义 Game.h:28
Shit::Game::IsRunning
static bool IsRunning()
主循环是否仍在运行
定义 Game.h:29
Shit::Game::Run
static void Run()
定义 Game.h:27
Shit::Game::GetInstance
static Game & GetInstance()
Shit::Game::Init
static bool Init()
定义 Game.h:26
Shit::Game::init
bool init()
初始化引擎所有子系统
Shit::Game::Game
Game(Game &&)=delete
