Use WSAD to move it. Very similar to the 3D example I made, so use WSAD to push it against the sides to bend it, like real copper wire.
All by me. The way it moves in the 3d way, is it makes an amount of clones, and each clone moves a speed depending on its size, so smaller segments(farther away ones) move slower, and the bigger(closer) ones move faster. Take a look inside to see!
