This is a labyrinth software which can be edited by you. This is an example in which direction we go:

Our goal is to have contributors like you draw parts of the labyrinth (Inkscape or hand drawn or other techniques), embed them into a huge labyrinth. Possibly, we can have multiple levels all stuck together.

Motivation

In the past two years, we created Flappy SVG. We had problems coordinating because this is all one SVG file. This time, we can allow contributors to work independently on a level and coordination comes with embedding. This allows remixing of each other's work and thus collaboration in new ways such as:

Adding your tile to an existing labyrinth
Creating your own labyrinth from other tiles.

It is possible to extend the level in various ways: Keys, asking characters in the game, animation, moving through the game, multiple levels. Also, we can create apps, credit pages and various other things with it.

Implementation

This will be an HTML/JS only site.

Contributions, Bug Reports, Feature Requests

This is an Open Source project. We would be happy to see contributors who report bugs, file feature requests and submit pull requests as well. Please have a look at the Contributing file for ways to contribute.

Issue and Branch Policy

Before making a pull request, please file an issue. So, other developers have the chance to give feedback or discuss details.
After writing your first commit, please open a pull request.

Match every pull request with an issue please and add the issue number in description e.g. like "Fixes #123".

We have the following branch

master
This contains shipped code. After significant features/bugfixes are accumulated on development, we make a version update, and make a release.

How to add new tiles

Labyrinth allows you to add your tiles by customizing the required javascript and svg files. There are various types of svg files which are available such as doors, floors etc.

Currently the tiles are svg images which are embedded into a div via javascript. Floor tiles have a dimension of about 429.544 x 256.314 px (wxh) Tiles are present in the tiles folder within subdirectories corresponding to particular tiles such as door, floor etc.

To create a tile you may use an svg editor such as inkscape. However other photo editors and formats do work if they are imported into the editor and saved as a svg file with the specified dimensions.

Note: if you are copying the template of a tile(floor) from an existing tile, then do not edit it as a png but directly as a svg. This is so that errors in alignment do not exist and the tile(floor) is perfectly aligned.

After creating tiles add them to the specific sub folder inside tiles.

Now, we will move on to the javascript part. Each tile's attributes and specifications along with it's declaration is done in the js/tiles.js file. You may edit this file defining attributes such as how you could enter and exit out of the tile and so on. You can also specify the door it takes, it's closed exit paths etc. A sample implementation should go into the already defined door class like:

tile_name: Object.assign({}, OpenDoors, {
    canEnterFromTheRight() {return false;}, /* Set these to false to block movements on the right */
    canLeaveToTheRight() {return false;},
    /* Simillarly you can have canLeaveToTheTop(), canEnterFromTheTop() etc. */
    createImages: function() {
      this.wallTop = this.createImage("tiles/rooms/wall/top.svg"); /* Alter these attributes to specify a custom wall tile for the floor tile.  Do not forget to implement the movements with canEnter/LeaveFromTheRight, ... */
      this.wallRight = this.createImage("tiles/rooms/door/right.svg");
      this.ground = this.createImage("tiles/rooms/floor/svg_name.svg"); /*  svg_name is the name of your svg */
    },
  }),

If you want to display an alert box when the character reaches your tile, your implementation must be something like this :

    visit: function() {
        alertNormal("title", "text");
        this.wallTop.show();
        this.wallRight.show();
        this.ground.show();
     },

Replace alertNormal with either alertNormal, alertInfo, alertQuestion, alertSuccess, alertError or alertWarning. For more info, read this.

And replace title and text with whatever title or text you want to display. If you want to only have a title and not any text, keep text empty. Like this : "".

After doing so now let's call the tile from the level so that they are reachable. You may modify `/js/levels.js` (which is currently the only level to include your tile. Something like `door.tile_name` since we have added it (our object) to the door (which is a class). You may use css to animate the svg if you wish.

How to add a new character

Labyrinth allows you to add your characters by customizing the required javascript and svg files.

Currently the characters are svg images which are embedded into a div via javascript. Characters have a dimension of about 55 x 60 px (wxh) Characters are present in the characters folder.

To create a character you may use an svg editor such as inkscape. However other photo editors and formats do work if they are imported into the editor and saved as a svg file with the specified dimensions.

After creating characters add them to the characters folder.

Now, we will move on to the javascript part. Each character has only difference in it's appearance and hence can be injected via putting its name and location to the svg file in gui.js. Follow the format while adding to gui.js (To be precise add it to the swal box input values collection i.e, into the inputOptionsPromise variable under the resolve sub class.)

"character_src": "character_name",

How to add new theme

Adding new theme is basically adding new tiles in a constant object:

const yourThemeName = {
  your tiles go here
},

While adding new theme you have to keep in mind theme structure. You can take a look at already existing themes.

After adding your theme to tiles.js file, you have to declare it in levels.js. Exactly its function, so it's going to create new tiles:

function createXLevel() {
  return new Level("X", [
    [X.none, X.right, X.right, X.right, X.right, X.none],
    [X.none, X.top, X.both, X.both, X.both, X.both],
    [X.none, X.top, PlayerStartsAt(X.start), X.both, X.both, X.top],
    [X.none, X.top, X.both, X.both, X.both, X.top],
    [X.none, X.top, X.top, X.both, X.top, X.top],
    [X.none, X.top, X.both, X.both, X.both, X.top],
    [NullTile, X.none, X.none, X.none, X.none, X.none],
  ]);
}

That's just an example of this function. Note that all these functions in levels.js file are looking very similar. Instead of X sign insert your theme name.

To make the level available to the player, best if you also add a tile which you place in an existing level which you want the player to explore before. This tile then calls player.addReachableLevel(createXLevel()) to make the level available to the player.

visit: function(player) {
    player.addReachableLevel(createXLevel());
    // ...
  },

How to add a new translation

Labyrinth needs your translations for make the game famous world-wide.

Go to the js\translate.js and find English text(like following) that you have to translate.
Check your language where there is or isn't. If not you can go to your language translation and find new strings not tranlated but in English translation

  'language': 'Select your language',
  'how': 'How to play',
  'credit': 'Credits',
  'game': 'Game',
  'contribute': 'Contributors',
  'statistics': 'Statistics',
  'moved': 'Player Moved :',
  'times': ' Times',
  'audio': 'Audio',
  'now': 'Now Playing : ',
  'by': ' by ',
  'share': ' Share Game ',
  'follow': 'Follow us on',
  'invent': 'Inventory',
  \\like these

Copy all the strings in English translate. And paste it after to last translation.
Change en to two or three letters related for your language. Those two or three letters must be not used earlier for any translate. Ex:- For Sinhala use si, for Polski use pl
Translate all the strings to your language and save it.
Add flag that realated to the laguage in icons(You can find flag from this place https://en.wikipedia.org/wiki/Gallery_of_sovereign_state_flags). The flag must be 255 X 128 pixels and it must be png file.
Go to HTML files(index.html, howtoplay.html, credits.html, contributors.html) from your code editor.
Then find following code from all the HTML files given and copy and past it after last language.

<div class="hover-black">
  <a class="translate translate-language-choice waves-effect waves-light btn blue-grey darken-2" id="en">
    <img src="icons/UnitedKingdom.png" alt="" class="translation-flag" />
     English
  </a>
</div>

Change img src="icons/UnitedKingdom.png" to your flag and change " English" to your language name. (There must be a space before language name.)
Now check all the pages from your internet browser and see it works.
Done, Push your changes and create a pull-request and have it merged.

How to Animate a Tile

Open the SVG file in Inkscape.
Click on the element you like to animate.
Go to Object > Object Properties or press Control+Shift+o.
Choose an Id for the object e.g. asdf. Please be aware that if you choose to animate a group, you may need to set the id again after you ungroup it.

Now, you described what to animate. Here is what you can do to add an animation:

Close Inkscape
Edit the SVG-File with a Text-Editor
Add the tag <style> to it and close it with </style>.
In between, you can add animations, see this tutorial using your Id, e.g. #asdf {}
When you animated something, you can view it in your browser.
