I'm about to try my hand at games programming and need lots of
help.  I want to make a few board games and need to know how to 
handle game pieces.  I need to be able to grab the pieces with the 
mouse, move them around tha  play area, rotate them, then drop them
in place.  Now I've read up on bobs and sprites in the RKM's, so I 
have an idea of how to program them, but how about rotating them on 
screen?  

Say I have a triangle piece and want to rotata it in one of eight
directions, is there a command that will let me do that, or do I 
need to make an image of it in each direction and redisplay it at
each rotation?  Also, how do I get it to follow the mouse pointer
when I hit the left mouse button?  One last question - when the piece
gets rotated, do I have to figure out all the aspect ratios, or will
the bob commands do that for me?

Thanks alot,

Matt Pierce
