Setting keyTimeValue.keyTime with setAttr

[Eduardo Grana]

Hello Guys,

Just a simple question.

I'm trying to set the time for a keyframe with

setAttr since i'm exporting and importing some curva data,

and with keyframe is a little more verbose and less code friendly

(for example keyframe -option over -index 0 -absolute -timeChange 2 pSphere1_translateX ;)

So I'm running into this error when i do
timeVar = 0
crv = 'pSphere1_translateX'
mc.setAttr(crv+'.keyTimeValue[0].keyTime', timeVar)
# RuntimeError: Maya command error #

and maybe you guys can give me some tip about whats going on.
Here is the simple code for you to test:

Thanks is advance.

Cheers!

Using the keyframe command doesn't seem too verbose or less code friendly to me. It feels like you have a lot of control over what you are changing, versus having to format a string in setAttr:

timeVar = 2
crv = 'pSphere1_translateX'
mc.keyframe(crv, e=True, index=(0,), o="over", tc=timeVar)

​

Does this not work for your needs?

Hey Justin,

Thanks for the reply.

Yes, I ended up doing some command call like that, but i was very curious about

what was the 'Maya command error' about, and how to set that 'time' attribute.

Another thing that i noticed, is that you get different data depending how you query,

for example

import maya.cmds as mc

# createa a sphere and set a keyframe
sphere = mc.polySphere()[0]
mc.setAttr(sphere+'.r', 17,17,17)
 
mc.setKeyframe()
 
 # get animation curve
crv = mc.listConnections(sphere+'.ry')[0] # rotation curve this time
 
# query values for key 0
time0, value0 = mc.getAttr(crv+'.keyTimeValue[0]')[0]

value1 = mc.getAttr(crv+'.keyTimeValue[0].keyValue') # same keyframe as before

print value0, value1, value0 == value1 # value0 is in radians and value1 is in degrees
>>> 0.296705972839 17.0 False

So if you want the values that you see in the graph editor, you have to be careful how you query.

Cheers!

Eduardo
