call action with typed params

[SteveSuv]

I can get state in client:

this.room.state.players.get(room.sessionId).x

why not use action like this:

this.room.action.startMove({ direction: 1 })

in server we can write:

export class CmdStartMove extends Command<GameRoom, { direction: number }> {
  execute({ client, direction }) {
      const player = this.state.players.get(client.sessionId);
      player.position.x += direction * SPEED
  }
}

export class GameRoomAction extends Action<GameRoom> {
    startMove = CmdStartMove
}

this.setState(new GameRoomState());
this.setAction(new GameRoomAction());

then the client not have to use room.send, but call the action with typed params.

it's be inspired by trpc

Hi @SteveSuv, thanks for your suggestions.

A trpc-inspired API would be super nice to have on the "final" Colyseus 1.0 version. I'd love to get there eventually. I think I'll be able to progress towards this only next year, though.
