for a 3D rotation RPG just have costumes on the sprite of every direction.then this is
the scripting bit
<when start clicked>
switch costume to:south
<forever> <if>
mouse down
<repeat until not mouse down>
switch costume to:<mouseX>
with a backgrondd you can choose to use the same script or to not use it,it really all depends on how you're making your RPG.check out my project '3D engine' to see one use of this scripting.
