Hi, I'm Daniel and fairly new to programming but I have this, probably a simple task, but I can't quite solve it. :-/ I have to rotate/move the line using a slider so that like the bottom of the line stays in the same place. I would love to post a picture to show what I mean but I can't since I'm not really active. But I really need some help or an example so I can try it by myself. I apologies in advance for my bad English or explanation.
