### The simplest way
[Go back to top](https://github.com/drgomesp/Fibula#navigation)

The simplest way to draw a tile map is to manually create the tile set, the layers 
and the actual map itself. Those are the basic components that make a tile map at the end.

> **Notice:** **Fibula** requires all image resources to be previously loaded. You can solve this
> issue by using asset management libraries, such as [PxLoader](https://github.com/thinkpixellab/PxLoader).

#### Orthogonal tile map

Suppose you have the following tile set:

![orthogonal-tileset](http://i1.wp.com/blog.sklambert.com/wp-content/uploads/2013/07/tileset.png?resize=512%2C512)

To get a simple example working, you first need to create a `TileSet` object. We're going to use
PxLoader to show you how to solve the asset management issue:

```javascript
var loader = new PxLoader(),
    tileSetImage = loader.addImage("http://i1.wp.com/blog.sklambert.com/wp-content/uploads/2013/07/tileset.png");
```

Now, we'll place our code inside of the callback function of the PxLoader library,
which will run as soon as the image is loaded and ready:

```javascript
loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage);
});
```

Here, we've passed the background image.

After having created a `TileSet` object, we need two more steps:

1. Create a first tile layer
2. Create the tile map and add the first layer to it
3. Create a renderer and actually render the tile map

So let's create the first tile layer, using the `TileMapLayer` object:

> *Notice:* All code from here will be place inside the addCompletionListener callback
function.

```javascript
loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage);
});
```

Now, let's create a first layer that will go on the tile map:

```javascript
loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage),
        layer1data = [

    var layer1 = new Fibula.TileMapLayer({
         name: 'layer 1',
         tileSet: tileSet,
         data: layer1data,
         visible: true,
         opacity: 1
     });    
});
```

Here we are doing some basic 2D mapping. The `layer1data` variable holds a simple 2d array
with 20 rows and 32 columns – which are the dimensions – in *tiles* – for our tile map, as you'll see
later. The numbers of each individual cell represents a spot on the tile set.

To understand this better, imagine you have each individual tile on the tile set
marked with a number - considering each tile having 32x32 dimensions, like the 
following image:

![orthogonal-tileset-marked](http://i2.wp.com/blog.sklambert.com/wp-content/uploads/2013/07/tileset_marked.png?resize=513%2C513)

So the next step is to create the `TileMap` object and the `Renderer` that will render it:

```javascript
loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage),
        layer1data = [

    var layer1 = new Fibula.TileMapLayer({
         name: 'layer 1',
         tileSet: tileSet,
         data: layer1data,
         visible: true,
         opacity: 1
     });
     
    var tileMap = new Fibula.TileMap({
        tileWidth: 32,
        tileHeight: 32,
        layers: [layer1]
    });
    
    var renderer = new Fibula.OrthogonalRenderer({
        tileMap: tileMap
    });
});
```

Here you see the usage of the `OrthogonalRenderer`, that knows how to render an
orthogonal tile map, and the actual `TileMap` object, holding the first layer.

The last step is to render the tile map. Here's an interesting part: you get to 
simulate a camera viewport and choose what part of the map is going to be rendered
and also the size of the camera viewport:

```javascript
renderer.render({
    x: 0,
    y: 0,
    width: 1024,
    height: 640
});
```

Here, we are rendering the whole map, starting by 0 on the `x` axis – left to right – and
0 on the `y` axis – from top to bottom.

Now, outside of the PxLoader callback function, we'll start to load the images and
the callback function will be triggered as soon as everything is ready:

```javascript
loader.start();
```

We should get a result like this:

![orthogonal-tilemap-ground](http://i1.wp.com/blog.sklambert.com/wp-content/uploads/2013/07/tileset_ground.png?resize=512%2C320)

As you can see, this is a one-layer tile map - which represents the ground of our 
map, and it's not very interesting. Let's create a second layer to add some objects 
on top of the ground:

```javascript

var layer2 = new Fibula.TileMapLayer({
    name: 'layer 2',
    tileSet: tileSet,
    data: layer2data,
    visible: true,
    opacity: 1
});
```

After the render, the result should look like this:

Amazing, right?!

With the layering system, you can work with collision detection by having the ability
to decide which layer will the player collide against and which the player will not.

Now, you can simulate a camera by passing custom view areas for the renderer:

```javascript
renderer.render({
    x: 200,
    y: 200,
    width: 300,
    height: 300
});
```

Here, we're using a camera with 300x300 dimensions and we start rendering the map on the 
200 pixel of the `x` axis and 200 pixel of the `y` axis. The result should look like this:

![orthogonal-tilemap-two-layers-camera](http://s13.postimg.org/9gdse24tz/Captura_de_Tela_2014_04_29_s_20_45_13.png)

#### Isometric tile map
[Go back to top](https://github.com/drgomesp/Fibula#navigation)

If you want to create an isometric tile map, the code for it is almost the same as
for the orthogonal. Suppose you have the following isometric tile set:

![isometric-tileset](http://s27.postimg.org/6c9sa3s0j/isometric_grass_and_water.png)

The first thing we need to do is create the first layer that will go into the tile map:

```javascript
var loader = new PxLoader(),
    tileSetImage = loader.addImage('assets/isometric.png');

loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage),
        layer1data = [
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 0]
    ];

var layer1 = new Fibula.TileMapLayer({
        name: 'layer 1',
        tileSet: tileSet,
        data: layer1data,
        visible: true,
        opacity: 1
    });
});
```

Now, we need to create our tile map object and the renderer:

```javascript
var loader = new PxLoader(),
    tileSetImage = loader.addImage('assets/isometric.png');

loader.addCompletionListener(function() {
    var tileSet = new Fibula.TileSet(tileSetImage),
        layer1data = [
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 3],
        [3, 3, 3, 3, 0]
    ];

var layer1 = new Fibula.TileMapLayer({
        name: 'layer 1',
        tileSet: tileSet,
        data: layer1data,
        visible: true,
        opacity: 1
    });
    
    var tileMap = new Fibula.TileMap({
        tileWidth: 64,
        tileHeight: 32,
        layers: [layer1]
    });

var renderer = new Fibula.IsometricRenderer({
        tileMap: tileMap
    });
});
```

Now let's render our tile map:

```javascript
renderer.render({
    x: 0,
    y: 0,
    width: 320,
    height: 320
});
```

> Notice here the usage of a 64x32 tile size for the map, which differs from the size
> of the tiles on the tile set in this case – 64x64 on tile set.

The result should look like this:

![isometric-tilemap-ground](http://s27.postimg.org/nqlsh6kr7/Captura_de_Tela_2014_04_25_s_15_31_15.png)

Now, let's add a new layer and make this map a little bit more interesting:

```javascript
 var layer2data = [
    [null, null, null, 4, 16],
    [null, null, null, 19, 23],
    [null, null, null, 19, 23],
    [null, null, null, 19, 23],
    [null, null, null, 19, 23]
];

var layer2 = new Fibula.TileMapLayer({
    name: 'layer 2',
    tileSet: tileSet,
    data: layer2data,
    visible: true,
    opacity: 1
});
```

After the render, the result should look something like this:

![isometric-tilemap-two-layers](http://s14.postimg.org/po0e3sic1/Captura_de_Tela_2014_04_25_s_15_34_12.png)

Amazing, right!?
