How do I make a grappling hook ?

I know, there is a tutorial, but i dont want that specific of grappling hook.

I would like to aim and click on a " hook " object in the scene. In my 2D plateformer.

When the player click on the hook, i want him to go the the hook and adding force to get a projection from the hook. Like thumbs.gfycat.com/VibrantHilariousFoal-size_restricted.gif
