If you have suggestions please help 
Hey!
It’s not too difficult to set up basic IK in Unity.
You will still need to build animations yourself that will help guide your character in the right direction, but the simple IK (Inverse Kinematics) solver in Unity allows for runtime adjustments of animations through scripting with very little overhead. Unity’s IK system supports the following functions:
- Placing hands where you want them.
- Placing legs where you want them.
- Causing the character to look somewhere with their head.
To get started with IK, I recommend the following couple of YouTube videos:
If you more prefer written documentation, Unity provides a walk-through of basic IK here:
Personally, I would suggest that you take the time to watch both videos AND follow the official written tutorial to get the most out of your IK solutions. It is, of course, your decision as a developer, though.
I myself have spent the last 3 days researching IK in Unity and just about everything simple is right here; past it gets very frustrating and complex. If you’re looking for more direct control & the resources I have given you here don’t cut it, I can expand upon them if you’re interested. Let me know if this helps, and if you run into any pitfalls, don’t hesitate to let me know.
Best of luck to you, and happy developing!!
