Game state is the subsystem that manages the current state of the game world. It manages a global instance of the GS struct, which keeps track of things such as the quantity of keys, coins, and charms collected; unlocked powerups; which cutscenes have been watched; and more.
Startup
The startup function, StartupGame, only calls StartGame.
StartGame
StartGame calls UnloadGame followed by WipeToWorldWarp.
UnloadGame
UnloadGame is called during startup and during a level transition if the ClearGame transition flag is set. It calls InitGameState, OnDifficultyGameLoad, and RetryGame. It also disables cheat codes by setting g_grfcht to GRFCHT::None and it sets the stored value for the previous level ID to -1.
InitGameState
The InitGameState function at 1605e8 resets fields on the global g_gs instance to their defaults. Specifically, it sets the following values:
| Field | Value |
|---|---|
| gameworldCur | GAMEWORLD::Intro |
| grfvault | 0 |
| gsv | 0x12 |
| cbThis | 0x1a00 |
| worldlevelCur | WORLDLEVEL_2 |
| clife | 5 |
| last_powerup | -1 |
It then calls a function which resets the game settings to their defaults.
Update
The update function, UpdateGameState, takes the current frame's dt as input and updates the play times on the global g_gs instance. Specifically, it adds the dt value to the current game play time (g_pgsCur->dt), the current world play time (g_wsCur->dt), and the current level play time (g_lsCur->dt). It does not call any other functions.
