+	<Function name='tween' return= '' arguments='float time, TweenType type, table params'>
+		Uses type to determine the tween to use.  The type must be one of the TweenType enum values.  If the type is note TweenType_Bezier, the params table is ignored.  If the type is TweenType_Bezier, then the params table must have 4 or 8 numbers.  4 numbers in the params creates a 1 dimensional bezier curve, 8 numbers creates a 2 dimensional bezier curve.<br />
+		It's usually more convenient to use Actor:linear, Actor:accelerate, and so on, rather than using Actor:tween directly.
