You can add DragonBones to Flash pro allthough it´s not the same and not all that useful for animators, for video and movies. For game animations and other small or scripted animations it´s a nice tool. http://dragonbones.github.io/getting_started_en.html
Dragonbones is an extension for Flash and can be installed from: http://dragonbones.github.io/getting_started_en.html
Few things to check:
1) Did you restart flash after the extension was installed. The extension loads only after flash is relaunched.
2) If you still dont see the extension -
If on Windows, do check the c:\users\<username>\AppData\Local\Adobe\Flash CC\ folder.
You should see only one locale folder here. if you see 2 folders then copy the contents of the folder that contains the Dragon bones swf to the other folder(which may be named like en_US). This can happen if the locale of Flash install and locale of extension install are different. Restart Flash.
You should have following files under <AppData>local\Adobe\Flash CC\<locale e.g en_US>\Configuration\WindowSWF folder
Else can you search for these files and copy it under the above mentioned lcoation.
Adobe Extension Manager is not installed along with Flash Pro CC installation.
When you open Flash and click on Help->Manage Extensions, if Extension Manager is not present the installation of this will be triggered via the creative cloud app automatically. Once this is installed you can install the required extensions.
Adobe plans to release a more streamlined animation workshop than flash. Flash has not been updated (it's codebase) much since it's release, and it's too resource-heavy on the client machine.
Also, there has been major pressure from Apple (a long-time ally of Adobe) to drop flash, as they do not support it in their mobile i-devices (not including laptops).
Long story short, Flash is likely to be deprecated.
As to whether Flash will be dropped or not - I do not think so: merely its role has changed/ Adobe did drop the ball in regards to the animation market, however. I think the loss of the bones tool is in line with this change in direction.
Perhaps the devs will bring back similar functionality in a future version of Flash, but I doubt it. The animation market is quite specialized, and products like Toonboom and Anime Studio have filled the gap.
For those who miss the bone tool, I suggest to invest in a tool like Anime Studio (the non-pro version is very inexpensive), which has an excellent bone-based IK system with full contraints (and is far more controllable and powerful than the old bones system in Flash ever was). My workflow consists of animating characters in AS, then import into Flash if required.
We are in the process of bringing back some of the features including motion editor, IK/Bone tool etc. with improved work flows along with a host of new features in the near future. With the transition to the creative cloud, we are planning to have multiple updates to the product throughout the year and you will see these features in an upcoming release.
Finally! Some communication! That is great news.
It´s just a mystery how bad Adobe has become about communicating positive news about Flash and how much that hurts us who use it and love it still.
Well, count me surprised. Let's just hope then the tools will be improved with real editable motion curves.
On the other hand, I've heard this song before now from Adobe, and I will believe it when I see it.
