odin-ldtk

Loader for LDtk files. Uses Odin's core:json to unmarshal data into structs.

LDtk is a modern 2D level editor from the creator of Dead Cells, with a strong focus on user-friendliness.

Current version: 1.3.3

The data definitions were generated with JSON scheme and QuickType for rust and then manually edited.

How to use

Put the ldtk.odin file to a ldtk folder somewhere in your project. Then you can just do this (the path might be different):

import "../ldtk"

And then:

if project, ok := ldtk.load_from_file("foo.ldtk", context.temp_allocator).?; ok {
    for biome in project.defs.biomes {
        // use biomes ...
    }

    for level in proj.levels {
        for layer in level.layers {
            switch layer.type {
            case .IntGrid:
            case .Entities:
            case .Tiles:
            case .AutoLayer:
            }
        }
    }

    // ...
}

Note: value in Field_Instance can be a different type depending on the data. For this reason the type is json.Value, which works like any in this case, and you can do whatever you want with it.

Example

There is an example of a basic 2d platformer in the example folder. It uses raylib for the tilemap rendering. The initial implementation is by @Smilex.

Hot to use:

cd example
odin run .
