IK in Unity

jhopppppp

How hard is it to do IK in Unity3D with the latest pro version of Spine?

I am making a game where an animated character will need to look at a ball and catch a ball with their hands using IK.

And will I still be able to use Mechanim in Unity?

Thank you,

Joe

Built in Spine IK is not supported once converted to Mecanim native animations. You can uncheck the IK option of the baking system and implement your own solution or a 3rd party ones since the target bones are exported correctly regardless. FinalIK is overkill for this kind of task, there are a few relatively easy to use free IK examples on the asset store.

Unity5 is introducing behavior graphs so it may be a moot point heh

Thank you for the response. I don't completely understand what you are saying, so I will try out the free version to test spine's capabilities once in Unity.

I think the answer is:
If you know how to program and use Unity, it's not hard to use Spine's IK in Unity. If you're new to Unity or to programming in general, you may have a hard time, as you would doing many other things.

Spine-Unity already has some built-in solutions you can use to get results faster.
You also have the option of coming up with your own solution if you really wanted to, since the source code for Spine runtimes are readable and editable for your needs.
If you do get stuck somehow, you can always ask questions here in the forums.

Spine-Unity doesn't really work with Mechanim pre-Unity 5 because Spine doesn't use Unity's animation system (since Unity's system has limitations).
But Unity 5's Mechanim is more flexible. And when it comes out, Spine and Mechanim will be able work together, once their interface gets implemented.
