:space_invader: About

TileMap Editor is a fat-free tile map editor with zero dependencies and a scalable, mobile-friendly interface.

:gift: features

• Multiple tileset support
• Multiple tilemap support
• Multi-tile selection and painting (drag select multiple tiles from the tileset)
• Tileset meta-data editing (Assign tags to tiles, automatic assignment of symbols to tiles)
• Animated tiles support
• Flipped tiles support
• Tilemap layers (as many as you like) with opacity and visibility
• Export boilerplate code for kaboomjs https://kaboomjs.com/ (wip)
• Customizable export data
• Resizable tilemap - non destructive too
• Paint tool, Pan tool, eraser tool, Bucket fill tool, Random tile tool, Pick tile tool
• Undo/redo system
• Responsive interface (scales down to portrait mode on mobile)
• Tiny footprint
• Easy I/O api that lets you transform and save data with ease

Planned:

• Paint tool modes (line, square, circle,etc)
• tiled i/o

Multiple tilemaps and tilesets are supported in one file/session

It also scales all the way down to a smartphone screen in portrait mode

You can flip tiles

It can even do animated tiles

The random tile brush can also use animation frames to place a random frame

:cyclone: Reason

But Todor, why are you making another tilemap editor with all these other ones out there?

While I am a big fan of Tiled and LdTk, for my case I was looking for something that neither had:

• Tiny footprint. Other tilemap editors are 60-100+ mb and require installation. Tilemap-editor is 30kb as of the time of writing this.
• Can be used by other js projects/web apps/websites. It has been designed to be a module, which you can plug in your project easily.
• No build process required, no webpack, no transpiling. Thats true, it's a single js+css file with no external dependencies!
• Runs everywhere - mobile too. The other available options can not run on android or ios.
• Responsive interface that scales all the way down to a portrait mode smartphone. Thats right, one of the goals is to let you make maps on your phone.
• Again it just uses vanilla javascript, no react, no webpack, no 1gb+ eaten by the node modules folder. Inspect its code in the browser and it all there clear as a day.
• No complicated build processes. Since it's just a js file, you don't need to wait for it to rebuild every time you change it

:eyeglasses: Getting started

$ git clone https://github.com/blurymind/tilemap-editor.git
$ yarn
$ yarn start

:book: Api

To get it from npm, you can run

$ npm i tilemap-editor
or
$ yarn add tilemap-editor

To use it, you can import it via require or in the index file like so

// include the js and css files
<link rel="stylesheet" href="styles.css"/>
<script src="tilemap-editor.js"></script>

<script>
TilemapEditor.init("tileMapEditor",{ // The id of the element that will become the tilemap-editor (must exist in your dom)
 // loads tilemap data which was saved before. undefined will start you with an empty map.
 // Takes a parsed json object with a data struct that tiled-editor can read (an object with maps and tileSets):
 // { maps : {...}, tileSets: {...}}
 tileMapData: ioJsonData,
 // tileSize is used to slice the tileset and give the tilemap the right sized grid
 tileSize: 32,
 // How many tiles is the initial map wide
 mapWidth: 20,
 // How many tiles is the initial map tall
 mapHeight: 20,
 // tileset images src (required)
 tileSetImages: ["https://i.imgur.com/ztwPZOI.png", "./free.png"],
 // You can write your own custom load image function here and use it for the tileset src. If you dont, the base64 string will be used instead
 tileSetLoaders: {
     fromUrl: {
         name: "Any url", // name is required and used for the loader's title in the select menu
         prompt: (setSrc) => { // Pass prompt ot onSelectImage. Prompt lets you do anything without asking the user to select a file
             const fileUrl = window.prompt("What is the url of the tileset?", "https://i.imgur.com/ztwPZOI.png");
             if(fileUrl !== null) setSrc(fileUrl)
         }
     },
     imgur: {
         name: "Imgur (host)",
         onSelectImage: (setSrc, file, base64) => { // In case you want them to give you a file from the fs, you can do this instead of prompt
             uploadImageToImgur(file).then(result=>{
                 console.log(file, base64);
                 console.log("Uploaded to imgur", result);
                 setSrc(result.data.link);
             });
         },
     },
 },
 // You can write your own tilemap exporters here. Whatever they return will get added to the export data you get out when you trigger onAppy

     kaboomJs: { // the exporter's key is later used by the onApply option

             downloadAsTextFile(text, "KaboomJsMapData.js");// you can use this util method to get your text as a file
         }
     },
 },
 tileMapImporters: {
     //similar to the exporters, you can write your own data importer, which will then be added to the file menu
     tiledImport: {
         name: "Import Tiled json file (TODO)", // name of menu entry
         onSelectFiles: (setData, files) => { // callback that is triggered when file(s) are selected.

             readFile.onload = (e) => {
                 const json = JSON.parse(e.target.result);
                 // At this point we got the json data from the tiled file. We need to convert it into
                 // a data struct that tiled-editor can read (an object with maps and tileSets):
                 // { maps : {...}, tileSets: {...}}
                 alert("Not implemented yet... pr welcome ;)");
                 return;// TODO tiled json file parser

                 setData(json); // Finally pass that to the setData function, which will load it into tiled-editor
             };
             readFile.readAsText(files[0]);
         },
         acceptFile: "application/JSON" // You can control what files are accepted
     }
 },
 // If passed, a new button gets added to the header, upon being clicked, you can get data from the tilemap editor and trigger events
 onApply: {
     onClick: ({flattenedData, maps, tileSets, activeMap}) => {
         console.log("onClick, gets the data too")
         const copyText = document.createElement("input");
