Scene Manager Session Example

Reviewed on: 2020-02-04

This directory contains an example implementation of a session that uses a SceneManager, specifically the FlatSceneManager, to handle rendering things to the screen.

Building scene_manager_session

The example sessions are included in the build when you include //src/session with your fx set:

fx set <PRODUCT>.<BOARD> --with-base=//src/session,//src/session/bin/session_manager:session_manager.config

To see a list of possible products, run: fx list-products.

To see a list of possible boards, run: fx list-boards.

Running scene_manager_session

Boot into scene_manager_session

To boot into scene_manager_session, first edit the session manager cml file to set the input session's component url as the argument:

args: [ "-s", "fuchsia-pkg://fuchsia.com/scene_manager_session#meta/scene_manager_session.cm" ],

and run

fx update

To build the relevant components and boot into the session, follow the instructions in //src/session/README.md.

Launch scene_manager_session from Command Line

To instruct a running session_manager to launch the session, run:

fx shell session_control launch fuchsia-pkg://fuchsia.com/scene_manager_session#meta/scene_manager_session.cm

Testing

Add --with //src/session:tests to your existing fx set command to include the scene_manager_session unit tests in the build. The resulting fx set looks like:

fx set <PRODUCT>.<BOARD> --with-base=//src/session,//src/session/bin/session_manager:session_manager.config --with //src/session:tests

To see a list of possible products, run: fx list-products.

To see a list of possible boards, run: fx list-boards.

The tests are available in the scene_manager_session_tests package. To run the tests, use:

$ fx test scene_manager_session_tests

Source Layout

The entry point and session units tests are located in src/main.rs.
