'''Game state''' is the subsystem that
==
The startup function, <code>StartupGame</code>, only calls <code>StartGame</code>.
=== StartGame ===
<code>StartGame</code> calls <code>UnloadGame</code> followed by <code>WipeToWorldWarp</code>.
==== UnloadGame ====
<code>UnloadGame</code> is called during startup and during a level transition if the ClearGame transition flag is set. It calls <code>InitGameState</code>, <code>OnDifficultyGameLoad</code>, and <code>RetryGame</code>. It also disables cheat codes by setting <code>g_grfcht</code> to <code>GRFCHT::None</code> and it sets the stored value for the previous level ID to <tt>-1</tt>.
===== InitGameState =====
The <code>InitGameState</code> function at 1605e8 resets fields on the global <code>g_gs</code> instance to their defaults. Specifically, it sets the following values:
{| class="wikitable"
▲|+
!Field
!Value
|-
|gameworldCur
! Address !! Type !! Name▼
|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, <code>UpdateGameState</code>, takes the current frame's <code>dt</code> as input and updates the play times on the global <code>g_gs</code> instance. Specifically, it adds the <code>dt</code> value to the current game play time (<code>g_pgsCur->dt</code>), the current world play time (<code>g_wsCur->dt</code>), and the current level play time (<code>g_lsCur->dt</code>). It does not call any other functions.
==Global values==
{| class="wikitable"
|-
|g_pgsCur||GS*||0x2623c0||Pointer to current game state
|-
|g_pwsCur||WS*||0x2623c4||Pointer to current world state
|-
|g_plsCur||LS*||0x2623c8||Pointer to current level state
|}
