Script which downloads all mixamo animations for one character.
// Mixamo Animation downloadeer
//
// Author: Antonio Aloisio <gnuton@gnuton.org>
// Contributions: kriNon
//
// The following script make use of mixamo2 API to download all anims for a single character that you choose.
// The animations are saved with descriptive long names instead of the short ones used by default by mixamo UI.
//
// This script has been written by gnuton@gnuton.org and the author is not responsible of its usage
//
// How to use this script
// 1. Browse mixamo.com
// 2. Log in
// 3. Open JS console (F12 on chrome)
// 4. Download an animation and get the character ID from the Network tab
// 5. Then past the character id in the "character" variable at beginning of this script
// 6. Copy and paste the full script in the mixamo.com javascript console
// 7. The script will open a new blank page.. you will start to see animations downloading
// 8. keep the blank page opened and keep on pressing "Allow multiple downlaods"
// NOTE. This doesn't really work for me, but it was supposed too
// Chrome will ask you all the time to allow multiple downloads
// You can disable this as follow:
// chrome://settings/ > Advanced > Content > Automatic downloads > uncheck "Do not allow any site to download multiple file automatically"
// CHANGE THIS VAR TO DOWNLOAD ANIMATIONS FOR A DIFFERENT CHARACTER
// const character = 'aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee'
const character = 'ef7eb018-7cf3-4ae1-99ac-bab1c2c5d419'

@gnuton please can you update the script to include a delay in downloading the next animation? I've tried using this multiple times & while it's great, the duplicate downloads are causing it to bypass some downloads, leaving around 1000 animations unobtainable via this method. Unfortunately I don't know JS enough to add this in.

Yo. I made a few fixes to the original script. Posting it here in case it helps people.
This version prevents the script from downloading multiple copies of a file, and when the API throws a 429 error it will wait 0.5 seconds and try again (until it eventually works).

For inplace animations add this before line 155:
gmsHashArray[0].inplace = true;

Hi, actually I changed it to 104 since I saw this is the last page number, and the problem occurs with that number. Another issue I now noticed is that it downloads a lot of duplicates, i.e it sometimes downloads the same animation several times. Thank you for your help!

I think it does that cause there's more than one like "jumping down" for example

If anybody is using this script try it in Microsoft Edge I did it in windows 11 and it worked just fine I got them all in Chrome it was a little hairy
