Examples
Using an image as the background
If you want to use an image for the background, remember you first have to declare your image assets and place all your files under the assets/scenes/ directory.
Script
Scenes Assets
1
Monogatari.script ({
2
    'Start': [
3
        'show background mountain'
4
        'end'
5
    ]
6
});
Copied!
1
Monogatari.assets ('scenes', {
2
    'mountain': 'mountain.png',
3
    'sea': 'sea.png'
4
});

Using CSS properties as the background
If you'll use CSS to set a custom background, you can use any valid non-spaced value for the background-image or background-color  CSS properties. Using CSS is perfect for when you want your background to be a solid color. Here are some valid statements:
1
Monogatari.script ({
2
    'Start': [
3
        'show background #fff'
4
        'show background rgb(0, 0, 0)'
5
        'show background url("assets/scenes/mountain.png")'
6
        'end'
7
    ]
8
});
Copied!
You can also use CSS gradients for backgrounds.
1
Monogatari.script ({
2
    'Start': [
3
        "We're about to show a linear gradient.",
4
        "show background linear-gradient(to right, red, yellow)",
5
        "Isn't that lovely?",
6
        "end"
7
    ]
8
});
Copied!
Using Animations
Monogatari comes with some built-in animations ready for you to use, you can see the list of animations and visualize them here. Using animations is as simple as indicating their name!
Script
Scenes Assets
1
Monogatari.script ({
2
    'Start': [
3
        'show background sea with fadeIn'
4
        'end'
5
    ]
6
});
Copied!
1
Monogatari.assets ('scenes', {
2
    'mountain': 'mountain.png',
3
    'sea': 'sea.png'
4
});
Copied!
Modifying an animation duration
The following will set the background to a solid color using a CSS value and modify the duration of the fadeIn animation to 20 seconds.
1
Monogatari.script ({
2
    'Start': [
3
        'show background #424242 with fadeIn duration 20s'
4
        'end'
5
    ]
6
});
Copied!
Creating a custom animation
You can also use CSS to create your own animations, you'll have to apply them to a CSS class and then use the show background statement as follows:
For example, note the following CSS code creating a simple Ken Burn Animation:
Script
Scenes Assets
CSS
1
Monogatari.script ({
2
    'Start': [
3
        'show background mountain with ken-burn'
4
        'end'
5
    ]
6
});
Copied!
1
Monogatari.assets ('scenes', {
2
    'mountain': 'mountain.png',
3
    'sea': 'sea.png'
4
});
Copied!
1
.ken-burn {
2
    animation-name: ken-burns; /* Name of the animation to use */
3
    animation-duration: 30s;
4
    animation-iteration-count: infinite; /* 1 if it should only move once */
5
    animation-timing-function: ease;
6
    animation-fill-mode: forwards;
7
    animation-delay: 0s;
8
    -moz-transition: ease 1s all;

    -o-transition: ease 1s all;

    -webkit-transition: ease 1s all;

    transition: ease 1s all;
12
}

@keyframes ken-burns {
15
    0%    { 
16
        transform: translateX(0); 
17
    }
18
    50%    {
19
        transform: translateX(-500px);
20
    }

    100%  {
