Ignoring Folder Meta Files On Version Control In Unity – Ignoring folder meta files in version control systems (VCS) like Git when working with Unity projects is a good practice. Here’s how you can handle ignoring .meta
files effectively:
Understanding .meta
Files in Unity:
- Purpose: Unity uses
.meta
files to store metadata associated with assets and folders in your project. This metadata includes information like import settings, GUIDs (Globally Unique Identifiers), and references needed for Unity to properly import and manage assets. - Version Control Considerations:
- Git: In Git, ignoring
.meta
files prevents unnecessary conflicts and reduces repository size. Since Unity can regenerate these files when importing assets, it’s safe to ignore them. - Other VCS: Similar principles apply to other version control systems like Mercurial (Hg) or SVN, though the specifics of how to ignore files might differ.
- Git: In Git, ignoring
Steps to Ignore .meta
Files in Unity with Git:
1. Modify .gitignore
:
-
- Edit the
.gitignore
file located at the root of your Git repository (if it doesn’t exist, create it). - Add a line to ignore all
.meta
files within the Assets directory and its subdirectories:
- Edit the
2. Apply Changes:
-
- Save the
.gitignore
file.
- Save the
3. Remove Tracked .meta
Files (if any):
- If you have already committed
.meta
files to your repository, you need to remove them from tracking:
This command removes .meta
files from the repository (but not from your local disk) and stops tracking them.
4. Commit Changes:
- Commit the changes to
.gitignore
and any modifications related to removing.meta
files from tracking:
5. Verify Ignoring:
- Verify that
.meta
files are no longer tracked by Git:
It should not show .meta
files as modified or untracked.
Notes:
- Regeneration: Unity will regenerate
.meta
files as needed when you import or modify assets. This ensures that Unity can maintain asset links and settings properly. - Collaboration: Ensure that all team members have the same
.gitignore
rules applied to avoid conflicts related to.meta
files. - Exceptions: Sometimes, there are specific cases where you might need to include certain
.meta
files (e.g., when sharing custom editor scripts or packages). In such cases, handle them judiciously to avoid breaking Unity’s asset references.
By ignoring .meta
files in your Unity project, you streamline version control operations and reduce unnecessary clutter in your repository, improving collaboration and maintenance of the project over time.
