Level Designer Toolkit (LDtk) is a modern, efficient and open-source 2D level editor with a strong focus on user-friendliness.

Getting LDtk latest version

Visit LDtk.io to get latest version.

Haxe compiler: you need an up-to-date and working Haxe install to build LDtk.
NPM: this package manager is used for various install and packaging scripts. It is packaged with NodeJS.

haxe setup.hxml

Install Electron locally and other dependencies through NPM (IMPORTANT: you need to be in the app dir):

cd app
npm i

First, from the root of the repo, build the electron Main:

haxe main.debug.hxml

This should create a app/assets/main.js file.

Then, build the electron Renderer:

haxe renderer.debug.hxml

This should create app/assets/js/renderer.js.

If you want to try a future version of LDtk, you can checkout branches named dev-x.y.z where x.y.z is version number.

IMPORTANT:

these dev branches might be unstables, or even broken. Therefore, it's not recommended to use, unless you plan to add or fix something on LDtk.
because dev branches might change quickly, you will need to update haxelibs often.
you will need to switch the LDtk haxe API to the same branch as LDtk repo. (adapt the branch name below accordingly):

haxelib git ldtk-haxe-api https://github.com/deepnight/ldtk-haxe-api.git dev-0.6.0

From a command line in the app folder, run:

npm run start
