Constant Movement Problem

[Zvjezdan23]

Hi everyone! =) Since my teacher can't help me out or doesn't respond when his hours say he's in his online office, I need some help. I am coding Tetris; and I have to say I'm doing a decent job so far. I just need help with constant movement. =/ I have made some test code that I am currently working on and using in my project. Can anyone help me out please??? =/ I really need the help.
