# Bouncing Ball Example

This directory contains an example application which draws an animated bouncing
ball using Scenic.

## Source layout

- `main.cc`: Main entrypoint for the component binary

## Before you begin

1.  Start a FEMU instance:

    ```
    $ ./third_party/fuchsia-sdk/bin/femu.sh --image workstation.qemu-x64-release -N
    ```

1.  Start a local package repository instance:

    ```
    $ ./third_party/fuchsia-sdk/tools/x64/fserve --image workstation.qemu-x64-release
    ```

> Note: This sample requires an image configuration that supports graphical
> sessions, such as `workstation`.

## Build the sample

1.  Run the build script to compile and package the sample:

    ```
    $ ./scripts/build.sh
    ```

1.  Publish the FAR package to your local package repository:

    ```
    $ ./third_party/fuchsia-sdk/tools/x64/fpublish out/x64/bouncing_ball.far
    ```

## Run the sample

1.  Launch the sample component using `ffx session add`. This resolves the
    component from the package repository and adds it to the session manager:

    ```
    $ ffx session add fuchsia-pkg://fuchsia.com/bouncing_ball#meta/bouncing_ball.cm
    ```

1.  Verify that you can see the bouncing ball animation on your display.

1.  If you have an input device attached, click the button to restart the
    animation.
