Hi everyone! I wanted to ask you guys a question. I was referred to this website by a friend of mine and I synced this account with my Facebook. I am new to computer programming, but I understand the beginning basics of C++ (i.e. cin, cout, void, float, vector, functions, structures, and so on). I am having difficult making a Snake/Tron-like game, which is why I am going to you guys. So here is my question: How can I make it to where a piece of mine keeps moving while a key is not held down / clicked? I have tried different ways, including the do this while (movement == KEYEVENTF_KEYUP); I need some help and it would really help me if I can get this accomplished.
Thank You Guy and Gals for looking at my post and code.
Sincerely,
-- Zvjezdan Veselinovic
