Is it possible in final ik to set additional gun mesh to the fps arms skeleton and link it with a constraint to use it as an ik target. I prefer a trigometric/fabrik.
example videos how it should look:
If you already know a script that would be awesome
Yes!
It’s not too difficult to set up basic IK in Unity.
You will need to deal with finger animations yourself using an external animation program, but the simple IK (Inverse Kinematics) solver in Unity allows for quick and simple IK solving with very little overhead. Unity’s IK system supports the following functions:
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.
Best of luck to you, and happy developing!!
