Plastic SCM plugin for Unity (beta)

Plastic SCM provides version control functionality for teams to collaborate on Unity projects.

The Plastic SCM plugin for Unity (beta) provides source control functionality from within the Unity Editor. The Plastic SCM window in the Unity Editor displays a list of new or changed files in your local project. From here you can check these files into Plastic SCM.

Any files you update in Unity are automatically checked out. This prevents other users from updating them until you check them back in.

The Plastic SCM plugin for Unity (beta) is supported for Unity 2018.4 LTS and above for macOS and Windows. Note: The plugin is not currently supported for Unity 2020.1 and above on Windows. Unity will add support for these versions in a future version of the plugin.

Getting started with Plastic SCM

Installing the Plastic SCM plugin for Unity

The Plastic SCM plugin for Unity is available on the Asset Store. To install the Plastic SCM plugin:

  1. Select Assets > Import Package > Custom Package…
  2. Select the PlasticSCMForUnity package.
  3. In the Import Unity Package window:
    1. Select All.
    2. Select Import.

The Plastic SCM plugin is now enabled on your project. To access the Plastic SCM window in the Unity Editor, select Window > Plastic SCM.

Creating a new workspace

To use the Plastic SCM plugin on a Unity project, you must create a workspace for the project in the Plastic SCM window or in the Plastic SCM GUI.

To create a new workspace for your project in the Unity Editor: 1. Select Window > Plastic SCM. 2. Specify the repository name, workspace name and path to the project. By default, the existing project path and name are used. 3. Choose whether you want to use Plastic SCM as a developer (for full Plastic SCM functionality) or an artist (for a simplified workflow).

Once you’ve created your workspace, the Plastic SCM window displays your project files. Additionally, Plastic SCM automatically creates an ignore file in the workspace, that is, your project folder.

Committing your project files to source control

Once you’ve connected your project to a Plastic SCM workspace, the Pending Changes tab of the Plastic SCM window displays all your existing project files as Added and private. To include these files in the workspace, you must check them in.

Once you have checked in your files, the Pending changes tab refreshes and no longer lists the files you have checked in. Additionally, the Plastic SCM GUI now displays:

  • Your project files in the Workspace Explorer
  • Your latest check-in in the Changesets view

Using the Plastic SCM plugin

The Plastic SCM plugin enables the Plastic SCM window in the Unity Editor. Use the Plastic SCM window to manage your file changes, including:

  • Link your project to source control
  • Check-in files
  • Undo changes
  • Compare file revisions

The Plastic SCM window displays a list of new and changed files in your project. When you add a new file, or save changes to an existing file, the Plastic SCM window automatically displays the affected files.

To open the Plastic SCM window, select Window > Plastic SCM.

Checking in files

To check in files:

  1. Select Window > Plastic SCM.
  2. In the Plastic SCM window, select the files you want to check in.
  3. In the text field, enter a comment to explain your changes.
  4. Select Checkin.

Your changes are listed in the Plastic SCM GUI, in the Changesets view.

Ignoring files

When you create a workspace using the Plastic SCM plugin, it automatically creates an ignore file in your workspace. This contains a default list of file types and paths to exclude from source control. If there are other files in your project that you want to exclude from the shared repository, add them to the ignore file:

  1. In the Plastic SCM window, right-click the file you want to ignore.
  2. Select Add to ignored list.
  3. Select the file name.

The files you choose to ignore are removed from the Pending changes list. You can ignore specific file names, whole folders, and all files with a specific extension.

Learn more about ignore files.

Viewing file changes

To compare an updated file with the previous version, right-click the file in the Plastic SCM window and select Diff. This opens the Differences view, which compares the repository source with your local copy. This is a text-only view.

Reverting file changes

If you’ve made changes in your project that you don’t want to keep, you can revert back to the previous version, that is, the latest checked-in version. To revert changes to a file, select the file in the Pending changes tab and select Undo changes.

Migrating to Plastic SCM

Plastic SCM provides a migration wizard to help you migrate projects from Collaborate to Plastic SCM. To migrate a project to Plastic SCM:

  1. Go to the migration wizard.
  2. Enter your Unity ID login details.
    1. Select Log in.
  3. Create a Plastic SCM organization.
    1. Select a region in the region dropdown.
    2. Select Next.
  4. Choose the projects to migrate.
    1. Select Next.
  5. Select the team members from your organization to join Plastic SCM.
    1. Select Next.
  6. Select Confirm.

Once you’ve completed the steps in the migration wizard, Plastic SCM migrates your projects from Collaborate to Plastic SCM. Plastic SCM also sends email invitations to the invited team members to get started with Plastic SCM.
