最近在學(xué)unity，想在unity調(diào)用python。因此學(xué)習(xí)了使用udp來建立通信。

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
serverAddressPort = ("127.0.0.1", 10086)      # 5052 定義localhost與端口，當(dāng)然可以定義其他的host

count = 0
while True:
    sock.sendto(str.encode(str(count)), serverAddressPort)
    count += 1
    time.sleep(1)
