help with Fake spring !!

i´m looking inside on Transform Delay Script : http://forums.cgsociety.org/showthread.php?f=98&t=344485&highlight=delay+position

first test:

Yellow box (script from Transform Delay Script):

at time(F-1) Sphereoffset =$Box01.pos - [0,0,0]
mypos=[-20,0,0] + Sphereoffset
at time(F-1) mymy = $Box01.transform
mymy.pos = mypos
mymy


Blue box (position script) :

at time (currentTime-1)
(
dragPos = $Box01.pos.controller.Zero_Pos_XYZ.value
)
dragPos


Red Box as master, just animate.

work well in objects independents, wich have no Hierarquy......when inside a chain, totally falls apart and guess it happen double tramsforms.....Oo

perhaps the MASTER must be outside of hierarquy....

NOT REALTIME, but update when changing time slider...
animate the "Dummy" to get the effect....

...keep going....

[Polimeno]

i couldn´t think how to get the "fake" when you drives only the "MASTER dummy" (parent of entire chain)........

guess dependsOn can do this, but i´m tring to avoid it....


help, please....

please,
anyone can help me how to write variables of OldPos and NewPos ???


OldPos = [0,0,0]

NewPos =
(
at time (currentTime - 5)
(
AnimObj = $.pos.value
)
AnimObj
)

atTime (NewPos)
(
AnimObj - OldPos
)



i just couldn´t think how to force objects to back to standard pose after some frames of animated point stops......
oO?

Here is an example of constrain transforms, it's something i dont really see people doing here - but its great for facial animation etc.

first store the transform space of the target 'point03' relative to its constraining objects,

tm1 = $point03.transform * inverse $Point02.transform
tm2 = $point03.transform * inverse $Point01.transform

Once these are store, keep them as a constant. For this test just comment them out as they've become a global. But for real use a CA to store these.

Then make a viable for your blend,

t = 0.5

Then we make two new variables holding the transform space multiplications.

nm1 = tm1 * $Point02.transform
nm2 = tm2 * $Point01.transform

We then grab the blend of positions of these spaces,

pm = ((1 - t) * nm1.pos + t * nm2.pos)

And then the rotation,

rm = slerp nm1.rotation nm2.rotation t

We build a final matrix using the rotation,

fm = rm as matrix3

and amend the last row using the position 'pm',

fm.row4 = pm

This is final transform for our point,

$point03.transform = fm
