Need to learn sliding style

Hello
I’m new in here and started to learn UE4 buy designing my own character for my project platform 2d game
I selected 2d side scroller game .
I’m looking for a video tutorial about creating slide on ground movement while running
does any one know how ?

This is probably not the best place to ask you would be a lot better off asking things like this in the blueprint section or something. There are plenty of examples out there but the only ones that come to mind are for wall slides or dashing etc. A floor slide is actually easier than that but you could probably use the same thing as a dash and simply change your animation to a floor slide since they are very similar.

Since you are new to this my suggestion is to watch this tutorial and also search for other 2d platformer tutorials that explain movement mechanics. The tutorial I am linking to explains wallslides and wall jumping which are common in 2d platformers. The concepts should help you better understand how to create a slide on the floor though as well as other movement types.
