Eva - basic Defold module, designed for mobile games with meta-game. It provides a lot of additional API and systems for easier game development. It contains a lot of different modules, which can be used separately.
DISCLAIMER: Eva is not documented well, some functions can be broken. Eva is in development, so API can be changed in future versions.
It is public in educational purposes, so you can see how I do different things and use it in your own projects. I will be glad if you will use it in your projects, but I can't guarantee that it will work well.

Setup
Eva setup and initial configuration is quite massive, please read install instruction here
Evadata format and export
For some modules there are defined specific basic structure.
Proto Eva data description can be found here.
Google document with data example can be found here.
Rules for export can be found here (using sheets-exporter).
Otherwise, all data can be filled manually with designed structure.
Tiled exporter
Eva have defined workflow with Tiled. There is a special module for that:
What it can do?
- Generate standalone Tiled tilesets from Defold assets folder
- Generate collection files with gameobjects, collections and tilemaps from created Tiled maps
- Generate Defold factory and collectionfactory for all tilesets used in generation. This is allow you create DLC folder assets for liveupdate for example
- Generate mapping file - list of all usable entities with a lot of additional info (size, properties, urls and other)
- Generate objects into Defold collections directly, without any code to spawn it (can be disabled via layer property)
Custom modules
Eva allows your to define new modules or rewrite existing one
