Introduction
This daz script is similar to mcjCycle filter,
it lets you synthesize animation curves or modify existing ones.
The name of the script comes from the fact that i needed to shift an animated figure up to ground-level,
but did not want to do it using null nodes.
Unlike mcjCycleFilter, there's no graphical plot of the animation curves
for long animations ( example 1800 frames ) displaying animation curves is very slow and not that useful.
History December 14th 2013 8 PM - fixrf issue with the extremities of looping-time-shifted. implemented the ''curPos'' constant and the ''pos'' variable December 13th 2013 released
Installation
C:\Program Files\DAZ\Studio\content\ C:\Program Files (x86)\DAZ\Studio\content\
once installed, it will appear in your content library, under Studio / Scripts / mcasual
or C:\Users\Public\Documents\My DAZ 3D Library\
USE Select the node to be processed
Launch the script
 Select the property or morph channel to be modified
in the example above i selected the Scale property
select the "Processing" to be performed
in the example above i selected the "set" process
which means that the "Scale" for the selected node will be replaced by the value i supply in the Parameter field
here i supplied the parameter 2
i could also type in a short script ... more about this later
specify the range of frames to be processed in the Time-Range section
here i selected the whole playrange
click the "do it" button
for each frame of the playrange , Scale will be set to 2
The Add function the value you type in the Parameter field will be added to the current value of the selected channel across the specified time-range
The Smooth function for each frame, an average will be computed it's the sum of the current value and its 2 neighbors, divided by 3
the extremities of the selected range are not modified
The Maintain Current function the value for the current timeline frame will be applied for the whole specified range
The Time shift function the animation curve will be shifted by the specified number of frames
negative numbers can be used
note that the mcjReTime script is better suited for cases where you want to time shift a whole pose-animation https://sites.google.com/site/mcasualsdazscripts2/mcjretimeanimation
The Looped Time shift function the animation curve will be shifted by the specified number of frames
the keyframes that "fall off" the end of the selected time-range are shifted at the start of the time-range
so if your animation was a looping animation, it will still loop after this
negative numbers can be used  The Reversed Time function the animation curve will be mirrored in time
so an object that was moving from position 0 to 10 will now move from position 10 to 0
Expert mode for nerds if you know a programming language like C or javascript or Daz Script,
then in the parameter field you can type script statements instead of a number
for example, if you select the "Add" process
you could type
as it processes the animation curve frame by frame, the script updates a few variables, and "ang" is one of those variables variables
fr : current frame processed, according to the specified time range ( so the first one is not necessarily zero ). ( modifying fr may lock D|S )
iFr : the current frame , zero based, the first frame processed is zero, the last one is numFrames-1 ( iFr = fr - startFrame ) x : progression along the range of frames, Zero for the first frame, 1 for the last frame ( x = iFr / ( numFrames - 1 ) ) ang is 0 radians for the first frame and 2π for the last frame processed ( ang = x * 2 * pi )
t : the Time, in internal Daz Studio units ( t = fr * tick )
val : the value of the selected prop for the currently processed frame
pos the World position of the selected node for the currently processed frame. A DzVec3. ( curPos.x, curPos.y, curPos.z );
constants numFrames: the number of frames in the timeRange;
startFrame the first frame of the range; endFrame the last frame of the range; curVal the value of the selected property at the current timeline frame;
node the selected node. a DzNode.
prop the selected property, always a DzFloatProperty
curPos the World position of the selected node for the current timeline frame. A DzVec3. ( curPos.x, curPos.y, curPos.z );
by default you must access the Math functions using for example Math.sin( ang )
but for your convenience i defined shorthand version for the most common like sin
so you can type sin( ang );
Typical script statements 30 * sin( ang * 3 + pi / 4 ) //3 Hertz sine-wave with a 45 phase
x * 100; // Ramp going from 0 to 100 over the time range
val / 2 // half the current value
30 * abs( sin( ang * 2 ) ) // rectified 2Hz sine-wave, looks like a bouncing ball
Save f(x) and Load f(x) buttons The content of the "Parameter" field can be saved as a text file and later re-used
