A tool on the Unity Asset Store: u3d.as/content/inicus-qvist/destructible-rope-cable-tool/bU1
Connect any two points with an automatically LODing destructible cable. Drag and drop into an industrial or city environment to add some interesting physics behaviour or an environmental hazard to your level.
• Specify two points and it will connect them with a physics rope, cable or pipe of any length.
• The physics rope is destructible, and comes with electricity particle effects and behaviour: Whenever an object comes too close, it will arc to it and send it flying away, and will also spark occasionally according to a random timer that you can adjust.
• Automatically changes LOD (Level of Detail) according to camera distance.
