How to achieve Grapple Hook like Fortnite and Batman Series

I want to achieve Grapple Hook like in Fortnite, I found a video on Youtube Video about Grapple Hook Tutorial, But that’s not what i actually want to achieve, it just dashes me into the Hit Point. In Fortnite you land on the surface of the object that you Hook. And i also want to control the velocity of the Grapple like in Batman Series. I am not good in maths and physics, i tried to launch My character at middle, but it just not working out. Please help me guys, Thanks in advance and Sorry for the bad English.
