ShowChallengeEvent

Announces one fight that has just started on the map the character is on, as a FightCommonInformation: the fight id, its FightType, the teams, the cells where each team's swords stand and each team's options.

WHAT TO DO WHEN YOU RECEIVE IT

1. Add the fight to the fights you track for the map. It is the same record, and the client turns it into the same client object with the same routine, as each entry of MapComplementaryInformationEvent.fights: a map's fights are known from its contents, and fights that start later arrive one by one in this message. 2. SEND NOTHING BACK. No handler of this message builds a request, and nothing the handling reaches does either. 3. Joining the fight or spectating it are separate player actions with their own requests; this message only makes the fight visible.

WHAT THE CLIENT DOES. The map-fights service converts the record and hands it on to the map's fight display. The same service also handles the map's fight count (MapFightCountEvent) and updates to a fight's teams. Adding a fight here does not change that count; on 3.6.12.16 only MapFightCountEvent sets it above zero.

YOUR OWN FIGHT IS ANNOUNCED TOO. The fight carries every team member, your character included when it is one of them, so a fight you just started by attacking appears here like any other.

ONE DECLARED MEMBER IS REAL. Builds pad this message with an optional int64, a second message member or a nested decoy; the client reads only ShowChallengeEvent.fight_information.
