Draw pixel-perfect 2D lines in the scene with any thickness and use them as if they were sprites. Lines are affected by layers, 2D lights, sorting layers and post-processing FXs. Add as many points as you need to create line strips and represent your ropes or cables, and update them every frame. Enable any of the visual effects available out of the box like dotted lines, textured lines, gradients, and more.
