// Inserting components inside a scene patches its content
MyScene [ // basically a div
Size { width: "100%", height: "50%" } // those components are just flexbox style options
Margin { top: "25%" }

AlignContent { kind: "Center" }
Size { width: "50%" }

Nice blog post! On the topic of scene/prefab formats, have you had a look at this?
It supports nested prefabs, field overrides in referenced prefabs, diffs/patches for fields etc.
Looks like we've been working on similar problems in different parts of the Rust community 😄

Hey guys, I have a few questions as I'd like to help out how I can...
Are Entity, MyScene,Container keywords? Perhaps they are structures within Bevy that are registered for usage?
Are there any current plans to use scenes within scenes - for example: QML would have "MyScene" be defined in a separate file.
Are there any current plans to add reactiveness and expressions to values? Such as width: otherContainer.width???
Are there any current plans to simplify the syntax? - instead of "50%" - just ignore the quotations?
What thoughts have been put in for the data to interact with a database?
How would a programmer know what data-types are usable?
Are there any current plans for "arrays" of entities?
I'm GUESSING that the entire scene here is more of a "template" - and Entity(5646142) is how you create a SPECIFIC entity - am I about right on that?

@kabergstrom @zutils I have a feeling those comments here are a bit hard to find here as comments on a gist. There is an issue in the bevy repository which is a bit more visible than than comments here. bevyengine/bevy#92

Hey sorry everyone I let this get buried in my email. Lets definitely move the conversation to github. Lots of good ideas here. @zutils maybe just copy/paste your questions there and i'll answer them.

@kabergstrom: we've already synced up on this, but im definitely excited for collaboration on this front :)
