Release v3.0.0

[detomon]

Changes

• A completely new implementation that is frame rate independent.
• Added new DMWBWiggleRotationModifier3D and DMWBWigglePositionModifier3D nodes to replace the now deprecated WiggleBone node.
• The previous behaviour of using the acceleration instead of the velocity for movement turned out to be unstable. Now the velocity is used.

Updated examples can be found in the examples directory.

New features

• The new spring_freq property replaces the stiffness property. It allows to set an exact oscillation frequency and has an equivalent behaviour to the old stiffness property.
• Support for free rotating and hanging bones (with some limitations).

---

Note

The new implementation uses SkeletonModifier3D nodes and requires Godot 4.3. A fallback version with an alternative implementation for Godot 4.2 can be found in the godot-4.2 branch.

Is there a way for me to know, how to convert the old Wiggle Bone values to the new ones?
Because I'm want to use the framerate independent version, but the results are just too different.
And it's very difficult to even come close to the old version.

Anyways, great work 🎉

I agree, it is a bit less intuitive to get the values right at first with this implementation.
There is no direct way to reuse old values. Try the following steps and test the behaviour after each:

1. For rotation, set "Linear Scale" to a relatively high value (e.g. 5000).
2. Try to match the old wiggle speed with "Spring Frequency" (more stiffness → higher frequency).
3. Try to match the damping behaviour (how long it takes to come to rest) with "Angular Damp" (rotation) or "Linear Damp" (position). This should match the old behaviour, but with a higher value.
4. For rotation, adjust "Linear Scale" to match the influence when moving the skeleton. Generally it is higher for smaller bones and lower for larger bones.
5. If you are using gravity or other forces, set them last as this can change the spring frequency and it will need to be adjusted again.

There may be certain cases where the behaviour is different and cannot be reproduced.
