Help with an add-on?

I have the grapplehook add-on in my server and I don’t really like it because of how unreliable it is. However, I was in another server a couple days ago and the owner of the server had edited some .lua files and made it that you would go straight to the place where your grapplehook shot with barely any swinging. It was almost as if there was no gravity when you shot the hook because you would fly to it. The owner said he just messed around with some of the lua files to make it not glitch as much and that happened also. If anyone could tell me how to do that or edit it for me it would be a great favor :smiley: thanks
