What does your .gitignore file look like for a Unity project?

Question

I'm starting out with Unity and I've noticed that even with small code changes result in a large git diff.

Originally, my .gitignore just had this: Temp/

but it's not doing much heavy lifting.

I found this .gitignore template on Github, but I'm curious if anyone else uses this--either as a starting point or as-is.

Answer 1

I use to use that same .gitignore with no issues at all, as-is. Works on both macOS and Windows.

/[Ll]ibrary/
/[Tt]emp/
/[Oo]bj/
/[Bb]uild/
/[Bb]uilds/
/Assets/AssetStoreTools*

# Visual Studio 2015 cache directory
/.vs/

# Autogenerated VS/MD/Consulo solution and project files
ExportedObj/
.consulo/
*.csproj
*.unityproj
*.sln
*.suo
*.tmp
*.user
*.userprefs
*.pidb
*.booproj
*.svd
*.pdb


# Unity3D generated meta files
*.pidb.meta

# Unity3D Generated File On Crash Reports
sysinfo.txt

# Builds
*.apk

Answer 2

I use Unity .gitignore template then added with *.unitypackage.meta From my experience, it is crucial to add *.unitypackage.meta so it won’t mess up when other PC clone the project that contains Unity Packages.

Why mess up? - "It's very common that an asset from the Unity Asset Store comes with .unitypackage files for optional features or compatibility add-ons. In such a case, the importer's machine will contain a .unitypackage and .unitypackage.meta file. The .unitypackage file is ignored by this template, but the .unitypackage.meta file is not.", Explain link.

Edited this might also serve the same purpose, !/[Aa]ssets/**/*.meta. Doc link
