I am new to Game Studio, and while I am beginning to learn it in a class that I am taking on game development, I do need a bit of help. Everytime I look up to find tutorials online, I do not have much luck. I know there is an official guide coming out at the end of this month, but I need to get started now. Can anyone suggest some good links for tutorials (that if needed to be downloaded are compatible with a Mac) or tutorials that do not need to be downloaded?
Also, I know Game Studio comes with a couple of meshes, but I am working from a project that was started before me, so can I get a little help with characters? Like, perhaps, how do you make a mesh a little smaller than it was before? The character is supposed to be an old man, and his body is the size of a football player. How can I make him look a little frailer?
Yes, people, I know I sound dumb, but this project began before I got a chance to learn the software. The quicker I can get the help, the better.

You probably need access to a PC to use any of the tutorials. There are some good ones, especially George Pirvu's C-Script tut.

To put your football player on a diet,
open him up in MED
select all
set the restrict button to horizontal
in the side window use the scale button to make him skinny
in the front window do the same

Voila! I wish my diet was that easy.
