I would like to change the tangent type of a selected key. The controller is a position xyz.

The script will create a key, select it and change the tangent type to constant.

This is what I got now: c = $.pos.controller[2]
k = addNewKey c currentTime #select
k.outTangentType = #step

The bold line doesn't work, does anybody know why ?

Thanks!

Just make another assignment of the Key and configure it:

...
k = c.keys[1] -- replace "1" for the keyframes' index in the controller.
k.outTangentType = #step

Thanks!

Your help has been helpful but I'm still having a problem. I want to change the tangent of a key for which I dont know the time.

Knowing the keys[x] select the x'th key I have adjusted my script like this

c = $.pos.controller[2]
k = addNewKey c currentTime
selectKeys c 0 currentTime
n = numSelKeys c ((-- No ""numSelKeys"" function for SubAnim:Zero_Pos_XYZ))
c.keys[n]
k.outTangentType = #step

Do you know why the numSelKeys doesn't work, or do you know an other way to select a key at the current time and change the tangent?

Thx again!

What's the actual error you're getting?

You're probably trying to move forward with an undefined "k", as RodBiffi suggested.

Also, are you trying to set all keys on c to stepped at the currentTime, or just the new/selected key?
