3D Inverse Kinematics Godot 4 Conversion (Partial)

[chrisl8]

This is an initial attempt to convert the 3D Inverse Kinematics demo, related to updating all Demos to Godot 4 Issue #697

The project doesn't entirely work yet, but it runs. I am still working on making it work fully, but at least it starts now instead of crashing and you can cycle through the scenes and read all of the text.

I'll keep updating this when I make more parts work. I leave it up to you if you want to merge it now or wait until I have made it more functional.

I hit some of the files with my code formatter, if white-space updates are not wanted I can remove those.

As I wrestled with this, somebody told me that Skeleton3D is going away, because it doesn't work. Is that true? It would explain why I'm struggling with it so much.

Now that we have Godot4.3 beta with feature freeze, it is time to implement this demo correctly

It needs to stress that this partial demo is not up to date with the latest 4.3 skeletonModifier.

there is now a project in c# using the latest skeleton3Dmodifier for IK

Thanks, and acknowledged that my work got the demo past some basic "won't even start in Godot 4" issues, but is far from a solution to the real problem.

Unfortunately my free time to work on this has evaporated. Glad I could help. I'll jump in again if I get time again, but for now I must leave what i was able to do here.
