Multiple issues fixed for seamless transitions:
Server lifecycle:
- SV_Shutdown before devmap in SVD_Play_f: drops old clients so
spectator doesn't land in slot 0 (recorded player collision)
- SVD_IsStarting flag prevents cleanup hooks from destroying demo
state during our own SV_Shutdown/SV_SpawnServer calls
- SV_SpawnServer stops demo playback on non-demo map changes
via SVD_CleanupPlayback (no disconnect, just state cleanup)
- SVD_CleanupPlayback made non-static for use from sv_init.c
Cvar handling:
- Use Cvar_Set2 with force=qtrue for CVAR_ROM sv_demoplaying
- Set cvar AFTER SV_Shutdown (old game module gone) but BEFORE
devmap (so new G_InitGame reads correct value)
- Set CS_SVDEMO configstring after devmap as backup for cgame
Game module:
- ClientBegin: set pm_type=PM_SPECTATOR after ClientSpawn (which
memsets ps). ClientThink_real normally sets this but is disabled
in demo mode.
- G_WriteSessionData: skip during demo playback so forced
TEAM_SPECTATOR doesn't persist to next normal game
- ClientThink: return early in demo mode (no server-side movement)
Removed debug prints and unused SVD_GetPlayMaxClients.
