Raw

Main Goal:

  • Import the shape raw data from an animate js.
  • We seem to have most or all of the data. Now it's an organization and cleanup question.

Subtasks: [x] Monkey patch createjs apis (see them execute) [x] How are shapes referenced in raw data [x] Animations are referenced and can be nested. [x] We can expose lib from an mutation (composition).

Preformatting steps for animate JS file:

  1. Remove self executing function and export as default
  2. Replace all references to createjs with cjs
  3. Replace all AdobeAn references with an

Entry point

There is only ever 1 animation. It is the name of the file and it's attached to lib as a MovieClip.

To get the lib.<filename>, return it from the an.compositions. The id corresponds to the lib.properties.id.

Next steps:

  • Access lib from the an file.
  • Private animation names don't matter.
  • Start fleshing out a parse method that is wired to the tests.
  • Hard to test Animate against Flash because Containers are replaced with Animations.

The relationships of Movieclips, Tweens, Containers, Shapes.

A Movieclip (animation) is comprised of: Any number of movieclips, containers or shapes being tweened. Has a bounding box and frame bounds.

From a coding perspective. We start with a root movieclip. It contains tweens of shapes/movieclips, and instantiates them.

Then you can recursively walk these shapes/movieclips.

A container

  • Grouping around movieclips, containers and shapes.

A shape

  • Base case - Path and fill and other shape vector properties.

A tween:

  • Andrew believes is only ever in a movieclip.
  • Moves a shape, container or movieclip.

Know issues

Raw shapes don't work correctly in our engine. They work when you import. But they stop working via an Action referencing an Animation.

Thoughts going forward:

  • Is wrapping a shape in a container an easy fix?

  • [YES] Is our game engine fundamentally broken for frame by frame animation.

  • [NO] What if the shape in the animate file is grouped before being tweened?

    • Andrew checked. Even if you group shapes. Animate unwraps them.

NEXT STEPS:

  • NOT DOING - Add CONTAINERS extension
  • named items
  • Deterministic imports of IDs for color tintings
  • Can we automatically determine entrypoint?
  • Deduping shapes
