My whole help file is not uploaded yet. It's there to merely give you an idea of what it will be like.
To make the character swim, you would simply have an OnControl event, and make water a certain control colour. When the ego is on that control, change the view to a swimming one.
Note that for doing that, you'd use the class system, not the kernels. When making your game, you should ALWAYS use the class system rather than kernels.
