Configuring System Entities

A single system entity lives at the heart of every Lumberyard application. The system entity's components, known as system components, power major systems within Lumberyard. You can use the Project Configurator's System Entity Editor to choose and configure the system components for your project. Editing the system entity for your project is like editing an entity in the Entity Inspector.

To configure system entities

  1. Compile a profile build of your project so that the Project Configurator can load your project's compiled code.

  2. Go to your lumberyard_version\dev\Bin64\ directory, and then launch ProjectConfigurator.exe.

  3. In the Project Configurator, select your project.

  4. Click Advanced Settings.

          Click Advanced Settings in the Project Configurator.

    The first time that you use the System Entity Editor, it performs the following tasks.

    1. Loads the configuration for your system entity.

    2. Identifies system components that are missing.

    3. Adds the missing system components to the configuration.

    4. Displays the list in the Added required components dialog box. The following image shows an example.

          Added required components in the System Entity Editor.


    Some system components are optional, and some are required. Both the Lumberyard engine and the gems that your project uses can require certain components.

  5. In the Added required components dialog box, click OK.

  6. The Project option shows the project that you selected. Use the drop-down menu to select a different project to edit.

          Choose a project in the System Entity Editor
  7. For the Configuration option, choose Game if you want to make changes to the system entity for the Game (launcher), or Editor to modify the system entity for the Editor.

          Choose the Game system entity or the
              Editor system entity

    The System Entity tab lists any components that have already been added.

          Added components for the system entity.
  8. To add a component to the system entity, click Add Component.

          Click Add Component to add a component to the system
  9. To see more information about a component before you add it, pause your pointer over the name.

          For a brief description of the component, see its tooltip
  10. To add the component to the system entity, select the component, and then click Save. The component appears in the list of components for the system entity.

  11. To delete, disable, or change a component's position, right-click the component and choose the corresponding action.

          Right-click a component to delete, disable, or move it.
  12. To configure system memory options, choose the Memory Settings tab.

          System memory settings in the System Entity Editor,
  13. Click Save to save your changes to disk. The changes that you make on the System Entity and Memory Settings tabs are saved to a Game.xml or Editor.xml application descriptor file.

Application Descriptor Files

When you edit a system entity's configuration with the Project Configurator Advanced Settings dialog box, you are actually editing an application descriptor file.

Application descriptor files list all modules that a project uses. Each project requires a Game.xml and an Editor.xml application descriptor file in its asset directory:



In the Project Configurator Advanced Settings dialog box, these files correspond to the Game and Editor options in the Configuration menu.

The following example shows the beginning of a Game.xml file. Both the Game.xml file and the Editor.xml file have the same structure.

The list of system components in the application descriptor file corresponds to the list of components on the System Entity tab in the Project Configurator, Advanced Settings, System Entity Editor dialog box. Each component can have its own settings. The application descriptor file also contains properties that determine how to allocate memory. These correspond to the settings on the Memory Settings tab in the System Entity Editor dialog box.
