ldtk-rs

Trying to integrate LDtk editor files as a bevy plugin (eventually). So far, have just mapped the JSON structure to Rust data structures (for the most part).

TODO

• fix linting errors
• finish the missing fields/types ("Objects" etc.)
• add a lot of deserialisation tests (deserialise)
• actually deserialise from a .ldtk file
• bevy
  • make it work
  • make it good
    • set up a custom asset + loader
    • design an API that makes use of this, i.e. map from the ldtk file to a bevy scene (entities, resources, components) and rust types
    • hot reloading
    • hot partial-reloading with diffing
• keep up with the changes to the LDtk file format

optional

• change from arrays of ints, to structs
• change from structs with optional fields, to enums with unique structs (challenging)
• add a lot of serialisation tests to ensure reproducability / round-trippability
• (bevy) make it interactive the other way (changes from the bevy app write to the ldtk file)
  • note: ldtk editor doesn't hot reload though

other ideas

• actually draw to a texture - see SiO2 or bevy::sprite::TextureAtlasBuilder
• construct a tilemap mesh, where its vertices UV-map many-to-many with a tileset (sprite sheet / texture atlas) texture - see bevy_tiled (but I think bevy_tilemap abstracts this away from us)
