Character Arm Joints.
I am currently working on a 2D game for a college project. I have a character and I want to try and simulate a semi-realistic joint between the upper arm and the lower arm of the character. The upper arm and lower arm are separate objects however I was wondering if there is a good way to simulate a hinge like joint between the lower and upper arm as the characters gun moves around. Looking at the image below may help explain it a bit better.
I could just parent the lower arm to the gun and rotate around where the lower arm is however that would probably look quite bad. I have been experimenting with Character Joints and I think that these may be the best way to do it.
I am just wondering what the best method would be to create this kind of behavior?

Traditionally you would parent the gun to the lower arm, lower arm to upper arm, upper arm to body, etc. That's the common setup for regular animated characters. If you want to move the gun and have that movement drive the arm, then look into IK, specifically 2 joint solvers, or even more specifically 2D 2 joint solvers.
I looked into I$$anonymous$$ however I saw that it was a pro - only feature so I was looking for an easy free alternative. I am on quite a short timeframe now and I would like to use the easiest possible method to produce this effect. I did mess around with character joints and they seem to be close to what I want, but they dont seem to work perfectly. Also I cannot use the animation system because the gun will be pulling the arm dynamically, not with an animation.
A little Googling ("unity I$$anonymous$$ script") goes a long way.
