Okay.I'll be totally honest with you.It doesn't work.Yeah,it does the job,it IS artificial intelligence,just a dumb one.I have no idea how to make it check player's moves.I'm a beginner,so please understand and help me.I really need help.Thank you in advance.
if i remember correctly there is an artificial intelligence engine called minimax. that is a very simple artificial intelligence that is really well made for this. also using functions and/or classes makes this so much simpler.
Minimax huh...I guess I went to far ahead beyond my abilities.I'll probaly leave this project for a while until I grasp more knowledge from C++.Thank you for you reply: D
