Bug Fixing

So, I finished modifying the character controller code, reverting back to the original method I was using to control the character and camera, and the problem still persists. It appears to be controlling some of the IK handles in local space, and others in world space, which is very problematic.
I checked the documentation, and found that the function for moving an IK handle in space, "Animator.SetIKPosition" only works in world space by default, and there seems to be no way in the function to set it to local space. Even though I had parented the IK handles, they were still moving around in world space, making it impossible to control my character's hands' positions relative to the character. I noticed that the only IK handle that was cooperating was the left hand grab handle, located deep in the hierarchy, parented to the rifle. I have no idea why this is the case. If parenting causes IK handles to work in local space, then they should, no matter how dep in the character's hierarchy they are parented. I have parented all of the hand IK locator objects to the rifle in the character's right hand, which may produce better results anyway.

It did not achieve better results, because they are parented beneath the root bones in the hierarchy, and therefore, they don't aim directly to the center of the screen, but rather wherever the character is facing in the animation, which causes the character to aim to the right whenever I press the fire button, instead the center of the screen, which is not what I want.

I re-parented the right hand IK locator objects, which control the shooting, to the character rig, and somehow it is miraculously working. The character's hands and rifle now stay where they are supposed to be relative to the character's position/rotation in space. I have also successfully rewritten my IK Control script.

So, I am back where I was before with the hands instantaneously moving to the positions of the IK handles. The coroutine waitforseconds values are also the same as before, to try and fake smoothness. I tried multiple methods to translate the handles or to somehow blend the weights, none of them worked. So, now it is time to move on and build other features. As you may notice, I also have a test environment built using Sabre CSG, a free Unity Asset Store plugin that works similar to Unreal's built-in level builder tool, using boolean tools I will build on this test environment as needed and use it to rest my character's abilities. We will see more of it later:

Here is the new IK Control script:
