No really - that's what it is! And it'll be functional once I get the script in it. However at the moment my attempts to navigate the wiki explanations of vehicle scripts are making my eyes cross. I will perservere! I thought that - although people could bring skates to use on the winter isle - having sleighs there would be fun. :)
Update: I found a simple vehicle script that I could modify and: Yes! It moves, it goes up and over bumps and hills, it comes back down, it turns, it stops. :) I even managed to find a simple "skate on ice" sound that doesn't work too badly.
It's these little triumphs that keep us going. :)
