PopLottie - Lottie Animation Renderer for Unity UIToolkit

Issues

Please submit any problems with rendering, with a lottie file, and ideally, what it should look like, with a ticket in github issues.

• Unity's ellipse renderer does not have 2D scaling, so is only scaled on the X.
• Trim-Path shapes are not implemented
• Rectangle shapes are not implemented
• Text layers not implemented

Usage

• Add this package to Unity Packages with Add Package from Git URL: https://github.com/NewChromantics/PopLottie.UnityPackage.git
• Add A LottieVisualElement to a UIDocument
• Set the Resource Filename to a file within your Assets/Resources/ folder. The filename needs to exclude the extension.
  • We're promised future versions of unity will allow asset-selection, but for now, we cannot implement custom inspector drawers, so filenames must be set manually.

Future Plans

Contributions for these are all welcome.

• Split BodyMovin parser from the renderer.
  • Options to output variables/uniforms for animated parts, to allow future use in shaders, or manual interpolation in render-command-cache
  • Options to output Editor/handle-control references back to layers & shapes to ease in-unity-editor editing
• Correct timing for user to control 0th frame time.
• async functions to play & wait for animations
• Looping controls
• Preview render of assets
• Swift Version
• Javascript version
• Shader renderer for use in texturing, projection, world space use.
• Optimisation!

Performance Notes

• Strokes are very expensive in unity's renderer! Having EnableDebug=true, which causes lots of control points of paths to be drawn, causes a large FPS hit!
