This is a list of all the avaliable functions that Zedd offers, as well as
which arguments they take and what values they return.  Functions marked with a * are
not included if you are installing a custom build of Zedd without the subroutine module

FUNCTION NAME		ARGUMENTS			RETURN		DESCRIPTION
----------------------------------------------------------------------------------------------------------------------
LoadZ(r1,r2)		r1 = X acceleration		None		Clears the Zedd object buffer, as well
			r2 = Y acceleration				as sets the global acceleration to
									r1,r2

AddZ(r1,r2,r3,r4,r5,r6)r1 = X position (pixels)	Index of	Adds a new object to the simulation, with
			r2 = Y position (pixels)	Object		position r1,r2 dimensions r3,r4 mass r5,
			r3 = Width (pixels)				and a sprite number of r6.  The objects
			r4 = Height (pixels)				frictional constant is set to the default
			r5 = Mass
			r6 = Sprite #

Del(r1)		r1 = Object Index		None		Deleted an object with index r1
									Object at the end of the list is shifted into
									vacant position

*PushZ(r1,r2,r3)	r1 = X acceleration		None		Accelerates an object with r1,r2 force, applied	
			r2 = Y acceleration				in 1/256 pixels per frame per frame
			r3 = Object index
	
*VelZ(r1,r2,r3)	r1 = X velocity			None		Sets the velocity to r1,r2, in 1/256 pixels per frame
			r2 = Y velocity
			r3 = Object index

*Fix(r1,r2,r3)		r1 = X fix flag			None		Sets the Axis locking on the object.  1 represents
			r2 = Y fix flag					fixed, while 0 represents free motion
			r3 = Object index

*FricZ(r1,r2)		r1 = frictional constant	None		Sets the frictional constant of an object
			r2 = object index

*X(r1)			r1 = Object Index		X location	Returns the objects X location in pixels
							(pixels)

*Y(r1)			r1 = Object Index		Y location	Returns the objects Y location in pixels
							(pixels)

*Xs(r1)			r1 = Object Index		X location	Returns the objects X location in sub pixels
							(sub pixels)

*Ys(r1)			r1 = Object Index		Y location	Returns the objects Y location in sub pixels
							(sub pixels)

*Vx(r1)			r1 = Object Index		X velocity	Returns the objects X velocity in 1/256 pixels 	per frame

*Vy(r1)			r1 = Object Index		Y velocity	Returns the objects Y velocity in 1/256 pixels 	per frame

*ObjAt(r1,r2)		r1 = Screen X			Object		Returns the object that is located at position r1,r2
			r2 = Screen Y			Index		Returns 0 if no object was found
