This project supports to create a server side game application more efficiently and more quickly (use smartfox server engine)
1. Handle server ready event
@ServerEventHandler(event = ServerEvent.SERVER_READY)
public class ServerReadyHandler {
public void handle(AppContext context) {
context.command(CreateRoom.class)
.agents(RoomProvider.lobby()).execute();
MyRoom[] rooms = RoomProvider.gameRooms();
context.command(CreateRoom.class).agents(rooms).execute();
for(MyRoom room : rooms) {
context.command(UpdateRoom.class)
.toClient(true).room(room).execute();
}
}
}2. Handle user join zone event
@ServerEventHandler(event = ServerEvent.USER_JOIN_ZONE)
public class UserJoinZoneHandler {
public void handle(AppContext context, ApiZone zone, MyUser user) {
context.command(Log.class).from(this).info("user " + user.getName()
+ " join zone " + zone.getName());
context.command(JoinRoom.class)
.roomToJoin("Lobby").user(user).execute();
}
}3. Handle user join room event
@RoomName("v")
@ServerEventHandler(event = ServerEvent.USER_JOIN_ROOM)
public class UserJoinRoomHandler {
public void handle(AppContext context, MyRoom room, MyUser user) {
context.command(Log.class).from(this).info("user " + user.getName()
+ " joined room " + room.getName());
context.command(Response.class)
.command("1").recipient(user).data(room).execute();
}
}4. Listen a request from client and auto response
Let's say you want to listen a "bet" request from client and you also you want to response to that client, you can do like this:
@Data
@ClientResponseHandler // use this annotation to auto response to client
@ClientRequestListener(command = "2") // use this annotation to listen a request from client
public class BetRequestListener {
@RequestParam("1")
@ResponseParam("1")
private int money;
@RequestParam("2")
@ResponseParam("2")
private int roomId;
public void execute(AppContext context, MyUser user) {
MyRoom room =
context.command(FindRoom.class).by(roomId);
context.command(Log.class).from(this).info("user {} has just betted {} chips",
user.getName(), btype.getMoney());
user.decreaseMoney(btype.getMoney());
user.increaseGameMoney(btype.getMoney());
context.command(UpdateUser.class)
.toClient(true).user(user).execute();
context.command(UpdateRoom.class)
.room(room).toClient(true).execute();
}
}5. Intercept a request from client
Let's say you need validate a parameter in a request from client (i.e money in "bet" request) you can do:
@Data
@ClientRequestListener(command = "2", priority = -1)
public class BetRequestInterceptor {
@RequestParam("1")
@ResponseParam("1")
private int money;
@RequestParam("2")
@ResponseParam("2")
private int roomId;
public void execute(AppContext context, MyUser user) throws Exception {
if(money <= 0) {
context.command(Response.class)
.command("2").recipient(user).execute();
throw new BadRequestException();
}
}
}We have used smartfox server engine, we must use key-value object like SFSObject, SFSUser, SFSRoom e.t.c, they make our source code too complex, hard to read and hard to map, example:
// public user var
UserVariable avatarPic = new SFSUserVariable("pic", "GonzoTheGreat.jpg");
// private user var
UserVariable dbId = new SFSUserVariable("dbId", databaseId);
dbId.setHidden(true);
// Set variables via the server side API
getApi().setUserVariables(user, Arrays.asList(avatarPic, dbId));We must spend a lot of time to declare, init variables. Some time we also have two or three user agent for each game and mapping an user agent to key-value object is hard. We think using POJO is good idea, so we make this project.
