Timeline Move Undo Off Please?

[neverman]

Is there a way to make timeline movements not que themselves into the undo function.
I do not want the timeline change to undo if i use the undo function.

I would think that this would be an option somewhere but i cant seem to find it. Has anyone found out how this can be done?

thanks alot :]

yes thats true ,,, its very annoying... even i hav suffered a lot of times......

many a times i lose my poses and i hav to do it all again...

i have never thought of taking timeline changes out of undo que... its a nice idea.....

but i have thought of another idea and that is to make a script that will save the poses and then we can import it to maya....
let see what we can do... keep this thread up

Well the timeline changes can be removed form the undoqueue with sacriptjob that monitors that last command queue.

But thing is what use is undo if it does nothing? I mean if posintt inst udoable what the hell is the use of it if you mispose? BEsides maya has n way pof knowing whether movins something should be undoable or is aprt of posing! Anyway i dont actualy see why undoing is so destructive for yoru posing, imean isnt the pose what your trying to undo!?

Anyway why dont you jsut redo stuff wnhen you undid too much? And yes maya can undo stuff withouf uing undo.

bBIggest problem of this is however thant maya will undo stuff invisibly from you if you diasble the timeline ops in the undoqueue leaving you quite blind of what you just did. wich can vreak havoc more then you expect.

I will try and work with the scriptjob monitor.

I have no problem with the undo not visualy on the frame i am on.
I would much prefer that the timeline was not in my undo que.

If i get something good working ill come back and post it.

I looked into this and the timeline is a bit problematic here. what id do is make a command with api that mimics currentTime and name that commend current time, the ctach it now overrides current time then jsut dont implement undo for it.

This is prettymucgh teh simplest api task you could psosibly manage to do.

Doing this with mel is rwelay hard to do without crashing some parts of maya with overrides.

HWEVER you can remeke the global timeline not to use currentTime directly but rather wrap it in a undoInfo -stateWithoutFlush 0 and undoInfo -stateWithoutFlush 1;

looking into it now

[joojaa]

Okay the timeline can be fixed by

CODE
timeControl -e -pc "undoInfo -stateWithoutFlush 0;" $gPlayBackSlider;
timeControl -e -rc "undoInfo -stateWithoutFlush 1;" $gPlayBackSlider;

but now this only applies to the timeline slider if you change time elsewhere it does not protect them so what youd need to do is find all the ways that you change time in and place similliar protectionblocks there

so fi for exa,mpe you use the k (time dragger tool) then you need to add similliar options there and in the dpe sheet etc etc.

Excellent - thanks a lot joojaa!

this is exactly what i needed.
i appreciate your time and effort in finding this solution.

One backlash i have found with this method is that not only does it remove scrubbing from the undo que but it also removes any key edits that you do on the timeline (move / scale - with the red shift select function) though other timeline edits like copy paste of keyframes seem to work.

[joojaa]

try adding a more undo togle into ..../mayaX/scripts/others/timeSlider.mel specificaly the prcedure playbackStateChanged. because the key edit come in between 2 calls of playback state changed, but the timeline move does not as far as i can see.

You cant have it all youknow. But you cant tell me i didnt do what you asked now can you i told you itll have drawbacks, in makeing this. But not what i tought of at the time but yes i didnt test it i just implemented tested that it does not undo and then left it at that. But yeah i knew it woudld probably have soe drawbacks.

[neverman]

heh ^^ correct you are Joojaa

if i find a fix i will post it - thanks for all the advice and implementation ^^

[joojaa]

try if this works any better for you:

CODE
timeControl -e -pc "undoInfo -stateWithoutFlush 0;" $gPlayBackSlider;
timeControl -e -rc "undoInfo -stateWithoutFlush 1;" $gPlayBackSlider;
condition -dependency playingBack -script
    "undoInfo -stateWithoutFlush (!undoInfo -q -stateWithoutFlush)"
    EnableKeyMove;

Atleast it worked for me, in brief testing. Let me lnow if it has some problems

oh PS to toggle this behaivour off (if you wanted to for some reason) use :

CODE
timeControl -e -pc "" $gPlayBackSlider;
timeControl -e -rc "" $gPlayBackSlider;
condition -delete EnableKeyMove;

[neverman]

Works perfect!
thanks Joojaa

I know this is a very old post, but I'm hopeing you can help me out.

This worked like a charm for the Timeline:

 timeControl -e -pc "undoInfo -stateWithoutFlush 0;" $gPlayBackSlider;
timeControl -e -rc "undoInfo -stateWithoutFlush 1;" $gPlayBackSlider;
condition -dependency playingBack -script
    "undoInfo -stateWithoutFlush (!undoInfo -q -stateWithoutFlush)"
    EnableKeyMove;

But I don't know Maya scripting well enough at all to know how to apply this to the other ways the Timeline can be effected.
What script should I use for:

The Play Button
Scrubbing with K inside the Curve editor 

Thanks
