python pygame - 多人游戏

Question

我想创建一个 "画点什么 "的游戏，至少有三个来自不同电脑的参与者。

我有一个代码，适用于两个玩家。有谁知道如何能让三个人或更多人参与？

...............................................................

这是我的服务器代码。

...............................................................

server = ""
port = 5555

games = {}
idCount = 0
currentPlayer = 0

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

s.bind((server, port))

s.listen()
print("Waiting for a connection, Server Started")

class Game:
    def __init__(self, id):
        self.connected = False

players = [Player(0), Player(1)]

def threaded_client(conn, player, gameId):
    global idCount
    conn.send(pickle.dumps(players[player]))
    reply = ""
    while True:
        try:
            data = pickle.loads(conn.recv(2048))
            players[player] = data
            if gameId in games:
                game = games[gameId]
                if not data:
                    print("Disconnected")
                    break
                else:
                    if player == 1:
                        reply = players[0]
                    else:
                        reply = players[1]

                conn.sendall(pickle.dumps(reply))
        except:
            break

    print("Lost connection")
    try:
        del games[gameId]
        print("Closing game", gameId)
    except:
        pass
    idCount -= 1
    conn.close()

while True:
    conn, addr = s.accept()
    print("Connected to:", addr)

    idCount += 1
    p = 0

    gameId = (idCount - 1) // 2

    if idCount % 2 == 1:
        games[gameId] = Game(gameId)
        players[0].connected = True
        print("Creating a new game")
        print("Waiting for another player")
    else:
        games[gameId].connected = True
        p = 1
        players[1].connected = True
        print("Game is available")



    start_new_thread(threaded_client, (conn, currentPlayer, gameId))
    currentPlayer += 1

我不知道这是否有帮助，但我有一个旧的2人游戏。

客户端：

    import socket, pickle, pygame, pygame.gfxdraw
    pygame.init()
    screen = pygame.display.set_mode((800, 800))
    pygame.display.set_caption('client')
    mysocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    port = int(input(f'port: '))
    mysocket.connect((socket.gethostname(), port))
    def player(pos, color):
        x1, y1 = pos
        x2 = x1+10
        y2 = y1
        x3 = x1+10
        y3 = y1+10
        x4 = x1
        y4 = y1+10
        pygame.gfxdraw.filled_polygon(screen, [(x1, y1), (x2, y2), (x3, y3), (x4, y4)], color)
    player1 = (0, 0)
    up, down, left, right = False, False, False, False
    while True:
        tosend = player1
        mysocket.send(pickle.dumps(tosend))
        player2 = pickle.loads(mysocket.recv(1024))
        screen.fill(0)
        player(player1, (0, 255, 0))
        player(player2, (0, 0, 255))
        pygame.display.flip()
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                break
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_UP:
                    up = True

                    left = False
                if event.key == pygame.K_RIGHT:

        else:

        x, y = player1
        x += xchange
        y += ychange
        player1 =(x, y)
    mysocket.send(pickle.dumps('stop'))
    mysocket.close()
