So I have a 2D game I have been working on. I used unity 2d IK and animation. I even entered it into the unity 2d challenge last year. https://connect.unity.com/p/jungles-of-maxtheria Here is blow on how to use them. It does not mention anything: https://blogs.unity3d.com/2018/11/09/getting-started-with-unitys-2d-animation-package/ I am now using 2019.1.3 and they are gone. In the package manager they no longer exist. Now they were preview packages but still. I looked in the asset store and could not find them. The baddies I created need the scripts so now they won't work at all. Anyone? Bueller?
