How to make the FPS controller slipping

Hello everybody !

Everything is in the title, how to make the FPS controller from standart assets slipping like it’s on icy ground ? Hard to go at full speed and hard to stop completely.

I found a tread about this problem but it was 5 years ago with a different FPS controler from, and I don’t find other help anywhere so I’m asking the question again if you don’t mind.

I’m new with Unity, I know I’ll have to modify some things in the FPS script and it looks like terrifying lol ^^. But I really want to learn how to do that because that’s something I’ll use again later.

Thank you very much for the help !

Can you show me your FPS controller script and I’ll see if I can figure out how to make it work.
