MrxSound

Byte-for-byte identical to resident/MrxSound — see that page for full documentation of its functions, inheritance, and events.

In the shell context

Defines the paired EnterShellState()/ExitShellState() functions for the front end specifically — called directly from MrxGuiShell._OpenShell/_CloseShell to load the ui_shell/ui_hud/music sound and wave banks and transition to the “shell” music state. The rest of this file’s paired Enter/Exit functions (pause, cinematic, attract, PDA, hijack, survival) are the same shared state façade used by both trees — written once to serve every caller regardless of which build reaches them.
