Navigation animation

In this example we are using Entering- and ExitingAnimation to make an interesting card swipe mechanism.

The card class

We define a class for our cards using the ux:Class syntax.

<Panel ux:Class="Card" Height="256" Width="256" Alignment="Bottom" ux:Name="p">
    <Rectangle Color="#eee" Opacity="0" ux:Name="overlayRect" CornerRadius="25" Layer="Overlay"/>
    <EnteringAnimation Scale="0.35">
        <Move X="-4" RelativeTo="Size" />
    </EnteringAnimation>
    <ExitingAnimation Scale="0.1">
        <Move RelativeTo="Size" Easing="QuadraticOut" Y="-1.3" Duration="1"/>
        <Move RelativeTo="Size" KeyframeInterpolation="CatmullRom">
            <Keyframe X="0.15" Time="0.15"/>
            <Keyframe X="0.2" Time="0.3"/>
            <Keyframe X="0.25" Time="0.45"/>
            <Keyframe X="0.2" Time="0.6"/>
            <Keyframe X="0" Time="1"/>
        </Move>

        <Change overlayRect.Opacity="1" Duration="1" Easing="QuadraticInOut"/>

        <Scale Factor="0.4" Duration="1" />
        <Rotate Degrees="-50" Duration="1" Easing="QuadraticInOut"/>
    </ExitingAnimation>
</Panel>

Navigation animation

We assign the Scale-property of our EnteringAnimation and ExitingAnimation in order to achieve the longer navigation animation. We use Move together with Rotate in order to achieve the curly movement. Keyframes are used to tweak this curl a bit further. It allows us to define a custom path for our animation.

<ExitingAnimation Scale="0.1">
    <Move RelativeTo="Size" Easing="QuadraticOut" Y="-1.3" Duration="1"/>
    <Move RelativeTo="Size" KeyframeInterpolation="CatmullRom">
        <Keyframe X="0.15" Time="0.15"/>
        <Keyframe X="0.2" Time="0.3"/>
        <Keyframe X="0.25" Time="0.45"/>
        <Keyframe X="0.2" Time="0.6"/>
        <Keyframe X="0" Time="1"/>
    </Move>

    <Change overlayRect.Opacity="1" Duration="1" Easing="QuadraticInOut"/>

    <Scale Factor="0.4" Duration="1" />
    <Rotate Degrees="-50" Duration="1" Easing="QuadraticInOut"/>
</ExitingAnimation>

Our resources

Our cards content is just an image asset. This is just to make the example smaller, since the focus is to illustrate the use of EnteringAnimation and ExitingAnimation.

Notice how we generate our items in JavaScript, and we data-bind directly to the file paths relative to project root. We can do that, because we have included the images in our bundle by adding this to our .unoproj file "Includes" section: "Assets/*.png:Bundle.

<App Background="#eeeeeeff">
