couple scripts to simulate skating/skiing movement
i had something like this in mind
though mine is a very basic attempt - i just threw it together to see if it was possible in GG, if i get chance i should rewrite it to be a much better version
slopes work best on terrain mode but if you want to use actual objects as your ski surfaces (allows you to be more specific about when and where the player will ski/skate) you can assign skateable.lua to them (and make sure you set some value in skate_surface_name = )
make sure skating.lua is always active = yes
p.s. only works in third person right now, you need to add some nil checks if you want to use it in first person
