i’m not add a curve in a keyblock of a mesh object (a curve for animation for a especific key = shape)
import Blender
from Blender import *
obj = Blender.getSelected()[0] #select active object
mesh = obj.getData() # get mesh data of object
mykey = mesh.getKey() # get datablock of keyframes information
myIpo = myKey.getIpo() # get Ipo datablock for keys (vertex animation, each blue line is a shape)
consts_in_myIpo = myIpo.curveConsts # give me a list of names (strings) of shapes in Ipo key datablock
curves_in_myIpo = myIpo.getCurve() # give me all curves of animation (name of curve = name of shape) ipoCurve object
how can i ADD a curve into a shape (that not have one yet) ?
this:
Shape Key Ipos are handled differently from other Ipos. The user can rename the curves, so string are used to access them instead of constants. The [Ipo.curveConsts](file:///media/usbdisk/CJD/Python/BPY%20API%20CVS%207-6-2006/BPY%20API/members.iinet.net.au/_cpbarton/ideasman/BPY_API/Ipo.Ipo-class.html#curveConsts) attribute for Shape Key Ipos returns a list of all defined key names.
dont work or i can’t understand it
Hi CJD, may I ask why you need this, is it about initializing the key curves, that is, just creating them with a default value?
Since the name of Key Ipo curves is the key’s name, there are no valid names for addCurve() when it is a Key Ipo, so I can’t add any new curves (“NameError: curve name is not valid”).
Or with
myKey.ipo['Key 5']=(1,0)
I get: “TypeError: creation or deletion of Shape Keys not supported”
From a quick test, I found out I can assign a full Ipo object to the key, like
i need copy shapes from diferent instances of a mesh to a final mesh, it’s rigth, but y like copy animation curves too.
if you copy shape to shape (based on scipt rvk1torvk2 from JMS) create new shape and copy ver location one by one, but can’t create or add new curve to shapes.
sombody have some idea? the API not work? i am an idiot (don’t reply this, please)?
I guess I am trying to do something similar as CJD, to append keys from morph targets saved as text files to an object using insertKey() and then add curves to the new keys. I am actually trying to copy the drivers, but at least getting the curves saves me some work.
CJD, Under 2.41, you can get the key curves with myIpo.getCurve(X), where X is the index of the shape key, not by name, if there is no curve, getCurve() returns None. I tried but could never guess that! (is that documented anywhere?)
Then you can create a new curve in the key ipo (ipo2) of the second object with ipo2.createCurve(‘Key X’) (regardless of how the key is named), and then add the nodes.
In the same way and the same problem, it seems that the Shape Widget Wizard returns the same error with the Blender 2.42 RC 1 or 2 .
I recovered the python/api_2x/ipo.c made just after the merging between the official CVS and the Orange projetc CVS : http://projects.blender.org/viewcvs/viewcvs.cgi/checkout/blender/source/blender/python/api2_2x/Ipo.c?rev=1.49&cvsroot=bf-blender&sortby=date&content-type=text/plain
to make a compilation and the function works correctly .
IPO.addCurve(“everything”) work if key named “everithing” exists, and (NOTE) name duplicates don’t are possibles now for adding names news. (it’s wight)
bye bye! nothing to wath here…
(coming soon i publish copy_all_shapes whith curves and ipo drivers support, and… size aplly factor!)
Base button “SI” or “Yes” for copy the first shape (basis shape)
select first destination mesh and last “from” mesh.
FACTOR is a mult size for shapes “copies”, NOTE: if basis shape its’n same “size” with new shapes, add weight modifi size. delete basis shape its a good idea here.
