This is only a proof of concept. The goal is get a 5 - 10s load time for a game (10 including offerings animation).
Easy, DbD has 3 simple advantages (and an uneccessary disadvantage):
- All players have the same game data and version
- All skins and map data are already stored on the users' systems, they've essentially been cached
- Updates are required, so each player's system knows what everything looks like and their rules of engagement
- Characters are static
- Characters do not change skins in-game
- Killer's stance (if applicable)
- Killer's power status
- Survivors' status (
HealtyInjuredDying)- Survivors' carried item
- Killer's stance (if applicable)
- The game has a ready-up feature (the 5s countdown)
- Once the 5s timer starts nothing can be changed: the map offerings (if used) can be read, decided, and produce a viable map
- Additionally, there is no need to "load" players into a lobby
- The player's screen is the same as the lobby screen... Why are they being moved?
- The sound notification can still be played, just load the other players onto the screen and change the angle
- This can be accomplished by setting a variable (
GAME_TOKENfor example) to the connected session's ID
- This can be accomplished by setting a variable (
After the 5s timer has started, the server could send back JSON data (for example) of what the map looks like, and where everything important is: players' location (5), killer's item locations (if applicable), generators' location (7), totems' location (5), chests' location (1 - 11), hooks' location (6 - 10, excluding basement), basement location, hatch location, exit gate locations (2), crows' locations, windows' locations, pallets' locations, lockers' locations, and mist level
