Expand description
A thin crate for people who just want to use ldtk files freely.
Why did I create this nonsense?
- LDtk-rs
uses code generation, it does not get autocomplete support from rust-analyzer.Also, there are special license restrictions on using that crate. - ldtk_rust uses
.except()
inside the crate, you can’t handle errors.
Supported LDtk file versions
^1.0.0
Usage
cargo add ldtk2
use std::{error::Error, path::Path, convert::TryInto};
fn main() -> Result<(), Box<dyn Error>> {
use ldtk2::Ldtk;
let map = Ldtk::from_path("tests/example.ldtk")?;
// or
let map: Ldtk = Path::new("tests/example.ldtk").try_into()?;
// or
let map = Ldtk::from_str(include_str!("../tests/example.ldtk"))?;
// or
let map: Ldtk = include_str!("../tests/example.ldtk").try_into()?;
Ok(())
}

Structs
This complex section isn’t meant to be used by game devs at all, as these rules are completely resolved internally by the editor before any saving. You should just ignore this part.
If you’re writing your own LDtk importer, you should probably just ignore most stuff in
the defs
section, as it contains data that are mostly important to the editor. To keep
you away from the defs
section and avoid some unnecessary JSON parsing, important data
from definitions is often duplicated in fields prefixed with a double underscore (eg.
__identifier
or __type
). The 2 only definition types you might need here are
Tilesets and Enums.
In a tileset definition, enum based tag infos
This section is mostly only intended for the LDtk editor app itself. You can safely ignore it.
This object is used in Field Instances to describe an EntityRef value.
This object is just a grid-based coordinate used in Field values.
This object is not actually used by LDtk. It ONLY exists to force explicit references to all types, to make sure QuickType finds them and integrate all of them. Otherwise, Quicktype will drop types that are not explicitely used.
IntGrid value definition
IntGrid value instance
This file is a JSON schema of files created by LDtk level editor (https://ldtk.io).
This section contains all the level data. It can be found in 2 distinct forms, depending
on Project current settings: - If “Separate level files” is disabled (default):
full level data is embedded inside the main Project JSON file, - If “Separate level
files” is enabled: level data is stored in separate standalone .ldtkl
files (one
per level). In this case, the main Project JSON file will still contain most level data,
except heavy sections, like the layerInstances
array (which will be null). The
externalRelPath
string points to the ldtkl
file. A ldtkl
file is just a JSON file
containing exactly what is described below.
Level background image position info
Nearby level info
In a tileset definition, user defined meta-data of a tile.
This structure represents a single tile from a given Tileset.
The Tileset
definition is the most important part among project definitions. It
contains some extra informations about each integrated tileset. If you only had to parse
one definition section, that would be the one.
This object represents a custom sub rectangle in a Tileset image.
IMPORTANT: this type is not used yet in current LDtk version. It’s only presented here as a preview of a planned feature. A World contains multiple levels, and it has its own layout settings.
