help me in mulitclient of this applicaiton
hello every body,,,
i am a new contact to this forum, i am july doglas from USA..
i am working in this programe, i write a hangman game in client server architecture but when i try to convert it to multiple client i couldn't know how to do that!!
i want server connect to mulitple client and each new one start playing with the pervious clients ( not starting it's own game ),, i think that it's good to put an ordering between clients so there is turn for each one..
i hope i descripe my problem clearly, please help me as fast as you can
