BlendTree Node to interpolate between values

[ca3games]

Describe the project you are working on

Fighting game

Describe the problem or limitation you are having in your project

I want to interpolate between rotations in the animations of a 2.5D fighting game.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

To allow AnimationTree 2D blend nodes to be used to interpolate the values of a variable, like having a certain rotation value set as the target of the animation 2D blend node, similar to how the tween node works.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

A node similar to the Tween node, but you can set diferent interpolation goals based on which current start value is closer to (Imagine a 3D sphere and your interpolation goal is the closest output goal you current value).

If this enhancement will not be used often, can it be worked around with a few lines of script?

It will be very useful as some kind of 2D blend lerp state machine.

Is there a reason why this should be core and not an add-on in the asset library?

No, this is a core function.
