Select the key only on the active channel

[dg3duy]

How is it possible to select the key only on the active channel and not on all other channels?

cmds.selectKey(time=(cmds.currentTime(q=1), cmds.currentTime(q=1)))

This code is thanks to the user of this forum mcw0

Hi!

The problem with this, is that you first need to know if the grapheditor exists, then you need to know if a curve is shown in the grapheditor. If one of these is not the case the script would throw an error that a normal user wouldn't understand. So you have to either add special error messages or result to just selecting every channel on the selected object again.

with custom error messages:

import maya.cmds as cmds

if cmds.ls(sl = True) != None:
    if cmds.animCurveEditor( 'graphEditor1GraphEd', exists=True ) == True:
        channels = cmds.animCurveEditor('graphEditor1GraphEd',q= True, cs = True)
        if channels != None:
            for c in channels:
                cmds.selectKey(c, time=(cmds.currentTime(q=1), cmds.currentTime(q=1)), add = True)
        else:
            cmds.error("No channel shown in Graph Editor")
    else:
        cmds.error("No existing Graph Editor found")
else:
    cmds.error("No object selected")

with defaulting to selecting every channel on selected objects:

import maya.cmds as cmds

if cmds.ls(sl = True) != None:
    if cmds.animCurveEditor( 'graphEditor1GraphEd', exists=True ) == True and cmds.animCurveEditor('graphEditor1GraphEd',q= True, acs = True) ==True:
        channels = cmds.animCurveEditor('graphEditor1GraphEd',q= True, cs = True)
        for c in channels:
            cmds.selectKey(c, time=(cmds.currentTime(q=1), cmds.currentTime(q=1)), add = True)

    else:
        cmds.selectKey(time=(cmds.currentTime(q=1), cmds.currentTime(q=1)), add = True)

I hope it helps!

@Kahylan it's a very good explanation, thank you very much! it's perfectly what I was needing to use.
