(Python) Using if and else to toggle between a weighted tangent and a non-weighted tangent not working.

[amaterasu-qbb]

I am not sure how to fix the problem. The else does not work.

https://forums.autodesk.com/t5/maya-forum/i-want-to-create-a-hotkey-to-toggle-between-weighted-tange...

import maya.cmds as cmds

# Non-Weighted Tangents. This is depends on preferences.
cmds.keyTangent(e = True, wt = False)

# set to Weighted Tangents.
cmds.keyTangent(e = True, wt = True)

# set to Non-Weighted Tangents, False.
if cmds.keyTangent(q = True, wt = True):
    cmds.keyTangent(e = True, wt = False)

# toggle Weighted Tangents.
else:
    cmds.keyTangent(e = True, wt = True)

It works until if. But I am unable to toggle Weighted Tangents and Non-Weighted Tangents using else. Any kind of suggestions are appreciated. I want to register and use this code as a hotkey.

Thanks,

Hi! everyone.

I found a code that works on Twitter and I want to share it.

The author of the code is @Anonymous on Twitter.

import maya.cmds as cmds

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

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]))

The last code is a great code that allows toggle Weighted Tangents and Non Weighted Tangents for each Graph in the Graph Editor.

Any advice or feedback you can give me would be appreciated.

Thanks,

Hi!

Your code works for me. Could it be that you left lines 2-8 in so you automatically set it to weighted before the if statement every time?

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)

Hi! @Kahylan .

Sorry for the delay in responding, thanks for your reply.

I appreciate your compliments on my poorly written code. I have asked for feedback in many places, but only you have given me feedback.

You have always helped me.

Maybe I am missing some basics. I tried to make a flowchart, but I was confused and could not write the code.

This led me to create 2 to 8 lines of code.

I thought I could toggle it with 9 to 15 lines of code, but in reality it was tough.

I didn't know about the 4-line technique in your code where you put == [True]: after the if.
