Had to watch it a couple of times to figure stuff out, and I still missed the. I have some ideas on why it is not working and some potential solutions I can try to implement.Īssuming I can get it working, I'll make a post about it here on the forums in the future :smile:
Without constraints, it reaches the target as expected, so I'm probably just missing something. Right now I have the base solver finished, but I cannot seem to clamp the rotation to the min/max angles without Godot going crazy. It should be a tad faster though, since it is written in C++ instead of GDScript.Ĭurrently I'm playing around with taking the CCDIK solver in this Unity repository and converting it to Godot. Last I knew, the SkeletonIK node also has no joint constraints, making it not quite as useful as I hoped when I first read about it. The SkeletonIK node also uses a FABRIK solver, though I think the implementation is slightly different. This makes the IK solver not quite as useful for simulating organic joints. Without joint constraints, sometimes joints, like elbows, can bend backwards. I kinda worked around it by making a middle joint target, but it is not ideal. The only thing that the IK demo does not have that can be a deal breaker is no joint constraints. Unfortunately, it seems the wiki page has since been taken down.

The article explains how the solver works and the code samples, with a little work, were relatively easy to convert to GDScript. I wrote the plugin based on this FABRIK IK solver from, surprisingly, the Roblox wiki. I'm glad the IK demo is of some help! Hopefully it shows how the plugin can be used through the examples. Self.rotate_y(-self.rotation_speed * delta) Self.rotate_y(self.rotation_speed * delta) Otherwise, when it comes to the time that I need a solution, I'll do my best make one that works well and will share it.Įxport(float) var translation_speed = 0.5 I figured I'd have to make my own implementation because I haven't found anything in Godot or from others that works well yet, but please let me know if such a thing exists. 3D Skeleton IK is something I'll probably want to be using in the future for 2 bone character arms and legs.

If anyone has any insight into how to make this work better, I'd also like to know about it. However, I'll share what I was able to produce below.
I spent some time experimenting with the node and so far I've found that it isn't super great, but it could be that I just don't know how to implement it well. 3D Skeleton IK has been a bit of a source of frustration with me too in Godot. I didn't actually know about the SkeletonIK node until reading this, so thanks for that.
