[Current situation]
According to the attached Godot official documentation in the guide below, to create an IK chain, you must select multiple bones and choose “Make IK Chain”. However, when attempting the same operation on Action Game Maker, the “Make IK Chain” option does not appear at all. Is Action Game Maker not compatible with IK chains?
The IK chain can be used there as well, since no changes were made from Godot in that area.
This guide uses Sprite2D.
It appears to differ from the guide that uses Skeleton2D and Bone2D. (The guide information may be outdated.)
When using Skeleton2D/Bone2D, IK can be configured via the “Modification Stack” option in the Skeleton2D node.
Thank you very much for the prompt and courteous explanation. It seems I will be able to complete the setup successfully using the procedure you provided!
