Addkeys to polygon vertex

[kakushi_52]

I'm new to pythonAPI.
MEL and python's setKeyframe is really slow and my computer freezes.
There is a polygon mesh which has about 10000 vertices and each vertex moves.

I have found the sample code at Autodesk website.

Creating keyframes for an animated curve

import maya.OpenMaya as om
import maya.OpenMayaAnim as oma
def addkeys(plugName, times, values, changeCache):
   # Get the plug to be animated.
   sel = om.MSelectionList()
   sel.add(plugName)
   plug = om.MPlug()
   sel.getPlug(0, plug)
   # Create the animCurve.
   animfn = oma.MFnAnimCurve()
   animCurve = animfn.create(plug, oma.MFnAnimCurve.kAnimCurveTL)

   # Copy the times into an MTimeArray and the values into an    MDoubleArray.
   timeArray = om.MTimeArray()
   valueArray = om.MDoubleArray()
   for i in range(len(times)):
      timeArray.append(om.MTime(times[i], om.MTime.uiUnit()))
      valueArray.append(values[i])
   # Add the keys to the animCurve.
   animfn.addKeys(
      timeArray,
      valueArray,
      oma.MFnAnimCurve.kTangentGlobal,
      oma.MFnAnimCurve.kTangentGlobal,
      False,
      changeCache
   )

The sample code:

addkeys('pCube1.tx', [1.0, 3.0, 5.0], [0.6, 1.2, 2.4], None)
 works well but, I can't select vertex like the following.

addkeys('pCube1.vtx[0]', [1.0, 3.0, 5.0], [0.6, 1.2, 2.4], None)

 Is there any way to do like it?

Many thanks.

Hello Hirofumi,

in this example

    "addkeys('pCube1.tx', [1.0, 3.0, 5.0], [0.6, 1.2, 2.4], None)"

you take an attribute of an object and make modification on it (translateX), but in this example:

     addkeys('pCube1.vtx[0]', [1.0, 3.0, 5.0], [0.6, 1.2, 2.4], None)

you try to make modification directly on the object (on the vertex).

If you want to make modification on vertexes you should write something like this:

    addkeys('pCubeShape1.pnts[2].pntx', [1.0, 3.0, 5.0], [0.6, 1.2, 2.4], None)

Dear Remus Avram,

Thank you so much for quick response.
It worked well!

Again, thank you so much.
