# Level editing - Basics

Level editing is currently supported on desktop only. You will need a built copy of the consuming game (an executable launcher and the corresponding `<game>-x.x.x.jar`). The JAR contains all the resources the game needs at runtime — it is essentially a zip file and can be unpacked with [7-Zip](https://www.7-zip.org/).

Extract the `data` folder next to the JAR. The structure used by Lisa Engine is:

```
data/
├── levels/
│   ├── objects/
│   │   └── *.png
│   ├── world1/
│   │   ├── level1.tmx
│   │   ├── level2.tmx
│   │   ├── levelN.tmx
│   │   ├── ...
│   │   ├── rule1.tmx
│   │   ├── rule2.tmx
│   │   ├── rule3.tmx
│   │   └── rules.txt
│   ├── world2/
│   │   └── ...
│   ├── worldN/
│   │   └── ...
│   ├── blocks.tsx
│   ├── objects.tsx
│   ├── tileset1.tsx
│   ├── tileset2.tsx
│   └── tilesetN.tsx
├── scripts/
│   ├── cutscenes/
│   │   └── *.json
│   └── *.json
└── resources.json
```

* `levels`: _Tileset_ `tsx`, _Tilemap_ `tmx`, and _Rules_ `tmx`/`txt` files.
  * `objects.tsx` — the _Objects_ that can be placed on the _Objects layer_.
  * `blocks.tsx` — the _Tiles_ used on the _Blocks layer_.
  * `tilesetN.tsx` — _Tiles_ for any other (purely visual) layer.
  * `rule1.tmx` — automapping rules for the _Ground layer_.
  * `rule2.tmx` — automapping rules for the _Grass layer_.
  * `rule3.tmx` — automapping rules for the _Water layer_.
  * `rules.txt` — list of rules applied on `Ctrl + M` (automapping).

* `scripts`: JSON files for cutscene scripts and in-game scripts.
  * `cutscenes/` — cutscene scripts, kept separate from in-game scripts.

* `resources.json`: registry of all resources used by the game (worlds, levels, textures, sounds, animations, …) in JSON format.
