Guys guys!
I did it!
My floor loop for my OP anim...damn I spent a lot of time redoing it and redoing it
and redoing it and redoing it...(6 times i think) I just had to calculate like the distance betwen every line (10 in the top and 30 in the bottom).
It may look like something normal and simple... and it actually is, I just didn't know about perspective too much and this helped me to learn.
I'm just happy.
