gameserver-sandbox-rs
This is a sandbox repository that implements a very small game server using actix and embedded DB sled.
This was inspired by Game Server in 150 lines of Rust.
It is also based on the DDD architecture.
Cuz a very simple implementation, an Entity has only a unique ID and position data.
However, cuz the DDD architecture, so probably easily extensible.
Purpose
Study of actix, sled, DDD architecture.
The purpose is not to make a full-fledged game server.
contribute
I am still new to Rust and DDD.
so, Any PR is welcome!
Todo
- create index route
- put html file for View
Process to actually CRUD the Entity, at this time GameServer does not process the Entity yetdone- Refactor(I don't know if this is necessary, the initial goal is to create a small game server, not to write good code.)
Simple specifications
This game server can only handle very simple entities.
Entity holds only id: u32 and pos: (i32, i32).
The id is randomly generated and shared as the ws session ID and Entity unique ID.
pos is the position data of the Entity, and the client draws another Entity based on pos.
# when client connected
When the client connects to the game server, the game server creates a new Entity with pos: (0, 0).
Next, register the id in the game server session list and send the id and other client entities data to ownself and the entity data to all other clients.
# when entity updated
When the client moves in the game, send the json of {x: X coordinate, y: Y coordinate} to the game server.
The game server updates the Entity position based on the received json and sends the updated Entity data to all other clients.
# when client disconected
When a client disconnects from game server, the game server removes the client's id from the session and send all other clients a {id: client.id, x: -1, y: -1} json.
The client must implement from this json to stop drawing the entity of the disconnected client.
