Rain Meadow

What is Rain Meadow

Henpemaz - I'm really torn between naming Rain Meadow just the game-mode that we're making, or maybe the multiplayer engine underneath it. Doesn't matter a whole lot atm though.

Core ideas

(read these thrice)

It's p2p and there is no central host* - There is no individual client responsible for loading all rooms and all worlds.

Players self-host whenever applicable - If for instance a player the only one to be using a room/region, then it's totally autonomous in managing the physics and everything in it. If an entity is closely related to a player, then that player should be the one responsible for simulating that entity so that it has zero lag.

No resource is simulated by two distinct players - For each resource there is an assigned owner, and that owner is the only one responsible for simulating it, and it's results are absolute.

Resources and Entities

Resources follow a lease transaction model - Resources such as room, worlds, can be leased and released. Who it gets leased to becomes the host, or owner, of that resource.

Leased resources can be subscribed to - If a resource (room, world) is already leased, it can be subscribed to. The host for that resource produces the data, and the subscribers consume the data.

Entities follow an ownership model - Entities can be added to resources, and removed from them. Entities have an owner and it is the owner's responsibility to fire events and update state for that entity.
