How to animate a models position and scale in RealityKit
To animate a models scale and position, create a new transform that adjusts its scale and translation and use a FromToByAnimation.
The code for the demonstration detailed on this post can be found at the tutorials/immersive-spaces/position-and-scale-animation branch of our open source tutorial linked below.
Specifically, the code that creates the animation can be found in the SampleImmersiveView under line 24.
This code:
- Creates a new transform based on the models current transform.
- Adapts the newly created transforms translation and scale.
- Creates the FromToAnimation using the transform derived in the previous point and that of the model.
- Applies the animation to the model using AnimationResource.generate(...).
