How To Get List Of Key Frames?

[sumo-kun]

Hi, can anyone tell me if its possible to get a list of all the keyframes for an object with a single command?
I've tried the findKeyframe function with various flags and it doesn't seem to work...
I'm thinking of maybe resorting to using a big loop to go through the animation and look for keys that way but that will be real slow!

Thanks for any help!

I'm not exactly sure what you want to know, and how you want Maya to present it to you..? do you want to know what frames have keys? or what the key values are? or something else?
I mean a single object can have hundreds of separate animation curves assigned to it.. each with different keyframes and values..

if you animate a cube (pCube1) moving and rotating then do:

listConnections -type "animCurve" pCube1;

you'll get a list of 6 anim curves, each one of which will (may) have different keyframes. If you do:

keyframe -q pCube1_translateX

you'll get the frames.. and if you do:

keyframe -q -vc pCube1_translateX

you'll get the values.. even if you could do all this with one command how would you interpret the result..?

does this help you any?

Ah, sorry, I should have made the question a bit clearer.
I would like to know which frames have keys for a specific object, on any curve. This is represented in Maya with the red ticks in the time slider isn't it? I was looking for a function which would return the time values of ALL the red ticks in a float array or something. I can get one at a time but not all of them it seems... As you can probably imagine, getting one at a time by scanning through the time slider for every joint is extremely time consuming!
Sorry if this is a bit of a dumb question. I'm a programmer making tools for artists

Thanks for any help!

Honestly best is you are a bit of an artist yourself if you do this job. Programmers often do not understand how Maya works and what is already build in to script it. But coding skills is always cool.

For your problem:
You actually want to know the times where keys are applied to an object, right?

With keyframe -q "pCube1" you get all times of all animated attributes. But you can't just querry a certain attr. because you don't know if there are others that have a different keycount.
So there is stringArrayRemoveDuplicates. Of course its for stringArrays but you can have a look inside it and modulate it top get a floatArray-version to use with keyframe -q "pCube1";.

CODE
global proc float [] floatArrayRemoveDuplicates(float $list[])
{
    float $item, $results[];
    int $index = 0, $found;

    for ($item in $list)
    {
        $found = 0;
        for ($result in $results)
            if ($result == $item)
                $found = 1;
        if (!$found)
            $results[$index++] = $item;
    }
    return $results;
}

floatArrayRemoveDuplicates(keyframe -q "pCube1");
// Result: 0 11 22 //

like this?

Ah!! Thanks!! That helps a load!! Just what I was looking for!

Yeah, I literally had to learn Maya in like a week and I am not quite familiar with all the funtions
Thanks for the help!

Yes this is the problem, it takes a 1 year to understand the basic ideas fully. This is also why you cant just take any programmer of the shelf. Because if you just have tradditional coding skills it dont take you very far im afraid. Youd still need the guidance of a experienced maya TD.

This usalay leads to coding by force (this happens because you must justify your job bt you cant) wich is NOT A good idea
