// l4d2-finale-next-campaign.sp — Left 4 Dead 2 SourceMod plugin
//
// On every successful finale, waits 10 seconds and then auto-rotates the
// server to the next campaign in a fixed order. Loops back to the start
// after Dead Center. Set-and-forget map rotation for 24/7 servers — no
// votes, no RTV waits, the game just keeps going.
//
// Build:
//   spcomp l4d2-finale-next-campaign.sp -o l4d2-finale-next-campaign.smx
// Drop the .smx into  addons/sourcemod/plugins/  on the server.
//
// Rotation order (13 campaigns total, L4D2 then L4D1):
//   Dark Carnival → Swamp Fever → Hard Rain → The Parish → The Passing →
//   The Sacrifice → No Mercy → Crash Course → Death Toll → Dead Air →
//   Blood Harvest → Cold Stream → Dead Center → (wrap)
//
// State:
//   g_CampaignIndex is in-memory — resets to 0 on plugin reload / server
//   restart. For persistent rotation across restarts, swap it for a
//   KeyValues file or a simple Cookie/SaveTextFile pair.
//
// Mission-lost handling:
//   Event_MissionLost is hooked but no-ops on purpose. L4D2's default
//   behavior on wipe (restart the same chapter) is preserved, so a wiped
//   team doesn't get cheated of a successful run by being yanked to a new
//   campaign. Only finale_win advances the rotation.
