In unity 3D I want to create a game where the user gets to create a 3D bridge between two 3D islands. I'm new to unity/C#. So I need some suggestions on what should I use and how to use them. I'm looking for a step by step instructions on this issue or some chunks of code that I can edit and combine. (I've seen some 2D videos about it, but they're not so helpful in my situation)
any help is appreciated, thanks in advance.
