Hello @ferdinand,
This is the final script for PositionX.
I made it a bit shorter for making it more easy to adapt this to PosYZ/RotXYZ/SclXYZ.
And I added a possibility to undo the complete action (e.g. if there was already a key, which got overridden and the user wants to revert this). I am not sure, whether the undo commands are in the right place, but after some research I placed the AddUndo before the stuff begins and it works so far. For all selected objects.
Just wanted to post it, because maybe some else needs something like this.
"""Sets the current relative pos/rot/scl x/y/z-component of the selected object as a keyframe at the current
time.
"""

Is there a documentation how to make a PlugIn of my 9 scripts?
I mean, atm I just saved them into ..\Maxon Cinema 4D 2023_0AF8E603\library\scripts
Maybe it's enough doing a nicely named subfolder there and to add the folder to search location. I don't know. I'll try it out. Never installed a plugin or had a look into a plugin structure yet.
Thank you very much again for your help, Sir!
Kind regards
Vannipo
