I want to create a hotkey to toggle between Weighted Tangent and Non-Weighted Tangent.

Hi! everyone

I am currently writing code to toggle between Weighted Tangent and Non-Weighted Tangent for the Graph Editor keys. To assign it to a hotkey. I found that this command can be used to toggle between Weighted Tangent and Non-Weighted Tangent.

import maya.cmds as cmds cmds.keyTangent(wt = True) import maya.cmds as cmds cmds.keyTangent(wt = False)

I want to switch using the if, but I can't do it. Why is it not working? What part of the program can I fix to have it work?

import maya.cmds as cmds cmds.keyTangent(wt = True) if cmds.keyTangent(wt = True): cmds.keyTangent(wt = False) else: cmds.keyTangent(wt = True)

Note: switching a curve from weightedTangents true to false and back to true again will not preserve fixed tangents properly.

I agree with this. Any advice you can give me would be appreciated.

Thanks,

Sorry for the late reply, @Anonymous on Twitter gave me the code: https://forums.autodesk.com/t5/maya-programming/python-using-if-and-else-to-toggle-between-a-weighted-tangent/td-p/1201111
The following code is based on the code he gave me. I hope it is useful.

import maya.cmds as cmds # Toggle Weighted Tangent, Non-Weighted Tangents. cmds.keyTangent(e = True, wt = not(cmds.keyTangent(q = True, wt = True)[0]))

import maya.cmds as cmds # Toggle Weighted Tangent, Non-Weighted Tangents by selected Anim Curves. selectedCurves = cmds.keyframe(q=True,name = True,selected = True) or [] for selectedCurve in selectedCurves: cmds.keyTangent(selectedCurve,e = True,wt = not(cmds.keyTangent(selectedCurve,q = True, wt = True)[0]))

Also, @Kahylan gave me a modified version of the code I posted in my Maya forum question. I think this will be useful as well.

import maya.cmds as cmds # set to Non-Weighted Tangents, False. if cmds.keyTangent(q = True, wt = True) == [True]: cmds.keyTangent(e = True, wt = False) # toggle Weighted Tangents. else: cmds.keyTangent(e = True, wt = True)

Thanks,

I Accept Solution to this answer but this is not by me, it was helped by @Anonymous and @Kahylan. But I accept the solution because it helps the community.
I would like to take this opportunity to thank @Anonymous and @Kahylan

Thanks to @Anonymous and @Kahylan's help, I was able to create a code to toggle between Lock Tangent Length and Free Tangent Length, so I will post it here as well.

import maya.cmds as cmds # Toggle Lock Tangent Length or Free Tangent Length. cmds.keyTangent(e = True, wl = not(cmds.keyTangent(q = True, wl = True)[0]))
