Assumptions

• There is a set of one on one PvP arena maps
  • PvP arena maps have the no_save flag set
    • This means if someone dies or disconnects there, they will not get back into the game there and cannot disrupt future matches
  • one on one maps are 50 x 50 tiles
  • There are 4 possible start positions on a one on one map
    • They should be somewhat equally far from each other
    • A player is warped to a random start position on the map
• You can play for fame or a practice match
  • Only one fame match per day per character
• You can only invoke the related atcommands only from the Hurnscald map
• The ladder is viewable as a .txt on the web server
• If a player has not played a match for 30 days, there is a -100 fame (ELO) static penalty
  • This repeats every 30 days for the player in question if still no matches are played
  • This penalty cannot take you under 1000 fame ELO

Registration

Players are registered for the PVP ladder automatically at lvl80

• Their ELO is set to 1000
• Their PLAYED_ONE_ON_ONE_FAME_MATCHES is set to 0
  • Similarly WON_* and LOST_* are set to 0
  • They are considered a newbie until they have played 20 fame matches (this 20 match separation comes from the ELO specification and their new ELO is calculated differently)

Challenging

• @pvp_check <nick>
  • Returns rank ELO played won lost
• @challenge <nick> <map> <'fame'|'practice'>
  • Fails if
    • Challenged player does not exist
    • Challenged player is not currently seen by your character
    • Challenged player is not at least lvl80
    • Either player already has a challenge currently (bool CHALLENGED ?)
    • Either player has LAST_PLAYED_ONE_ON_ONE_FAME_MATCH == today
  • The challenged player is notified by a server message of challenging player rank, ELO (fame) and amount of played/won/lost fame matches
  • The challenged player has 5min to respond to the challenge or the challenge expires
    • The server message to the challenged player repeats every minute

Accepting / declining a challenge

• @accept_challenge (@ac ?)
• @decline_challenge (@dc ?)

A challenge is accepted

• If the requested ladder map is currently free (recheck every 1min)
  • Their status in the queue for the particular map should be announced to them every 1min
    • If either player is disconnected during queueing, a static -10 fame (ELO) penalty is applied to that player
      • Match is cancelled and both players are removed from the queue
      • No bonus fame (ELO) for the other player
  • Upon succesfully starting a match, set the appropriate LAST_PLAYED_*_MATCH (YYYY-MM-DD) for both players
    • Set PLAYED_*_MATCHES++
  • Give a countdown of 10 seconds to both players as whispers and warp them to the map
    • Lock the map for the duration of the match
    • Start a countdown of 5 minutes upon the match starting

End of battle

• After result calculation, announcement and a 30 second wait period, warp players out and free the map lock
  • Set appropriate WON_* and LOST_*
• If 5 minutes are full and both players are alive
  • -100 ELO (fame) static penalty for both, no real ELO calculation
• A player disconnects or times out or dies
  • Remaining player wins, count new ELO (fame) for both
  • Announce the result and ELO + ladder rank changes to both players with a 30s delay so they get the results when they're back in the normal game and not in the arena anymore
