Is there a working crawling script? If so can ya help?

I need a working crawling script so then when you hit C the player crawls im not that good at scripting and im not that sure what I would need to do

You can use UserInputService for your current situation. As for a crawling animation you will have to create that yourself from scratch, since animations between players can't be shared.

Here's some help explaining how to use UserInputService, this should help you a lot. It helped me a ton when I started learning how to script a couple months ago.
