Unity CLIの使い方

9 min read

ビルドシステムつくったりで、必要なコマンドオプションを調べることはありつつ、
どんなことできるかあんまり知らなかったなと思ったので、ざっくり調べてみた.

環境

  • PC: mac
  • OS: macOS Montery
  • Unity: 2021.1.28f1

Usage

まずはInstall Locationを確認

/Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity

help

help optionはないっぽい. GUI文化だ.
使い方はwebのdocを見るほかなさそう

version

定番のversion表示

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity -version
2021.1.28f1

license

CI組み込もうとするとたまにつかうやつ.
GUIでログイン済みならSkipでOK.

$ /Applications/Unity/Unity.app/Contents/MacOS/Unity \
  -quit \
  -batchmode \
  -serial SB-XXXX-XXXX-XXXX-XXXX-XXXX \
  -username 'JoeBloggs@example.com' \
  -password 'MyPassw0rd'

返却

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity \
  -quit \
  -batchmode \
  -returnlicense

create project

-createProject <Project> でプロジェクトが作れるっぽい
1分くらいかかる感じだった. プロジェクトの様子が見えないので、手元ではGUIで作る方が楽ちんではあるかも.
作成自動化作業とかがある場合は、便利そう!

あとは CLIとして使う時には、 -batchmode -quit 常時つける感じがよさそう.
-logfile - はLogの標準出力だった。

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity \
  -batchmode \
  -quit \
  -createProject GreatSampleUnity \
  -logfile -
...

Exiting batchmode successfully now!

.sln も作られるのは地味にありがたい. Scenesフォルダは作られないみたいだった

$ ls -lha GreatSampleUnity

build

まずビルドスクリプトを書く (雑)

namespace Sample
{
    public static class Builder
    {
        public static void Build()
        {
            var scenes = EditorBuildSettings.scenes.Select(x => x.path).ToArray();
            var options = new BuildPlayerOptions
            {
                target = BuildTarget.WebGL,
                targetGroup = BuildTargetGroup.WebGL,
                locationPathName = "Build",
                scenes = scenes,
            };

            if (!Directory.Exists("Build"))
            {
                Directory.CreateDirectory("Build");
            }

            BuildPipeline.BuildPlayer(options);
        }
    }
}

あとは -executeMethod <NamespaceName.ClassName.MethodName> で行ける.
-projectPath での指定も忘れずに

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity \
  -quit \
  -batchmode \
  -projectPath . \
  -executeMethod Sample.Builder.Build


Aborting batchmode due to fatal error:
It looks like another Unity instance is running with this project open.

Multiple Unity instances cannot open the same project.

Project: /path/to/GreatSampleUnity


zsh: abort      /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity -quit   .

すでにlocalでUnityのGUIモードを起動中だと↑のようなエラーになるので注意.

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity \
  -quit \
  -batchmode \
  -projectPath . \
  -logfile - \
  -executeMethod Sample.Builder.Build

logfileは付けておかないと動いてるのかどうか怪しくなってprocess killしたくなるので付けておくのが吉.

ちゃんと出力されている.

$ ls -lha Build
total 16
drwxr-xr-x   5 mattak  staff   160B 12 16 00:00 .
drwxr-xr-x  14 mattak  staff   448B 12 16 00:00 ..
drwxr-xr-x   6 mattak  staff   192B 12 16 00:00 Build
drwxr-xr-x  12 mattak  staff   384B 12 16 00:00 TemplateData
-rw-r--r--   1 mattak  staff   4.8K 12 16 00:00 index.html

test

-runTests, -testResults -testPlatform あたりがそのオプションだった.

$ /Applications/Unity/2021.1.28f1/Unity.app/Contents/MacOS/Unity \
  -batchmode \
  -projectPath . \
  -logfile - \
  -runTests \
  -testResults ./results.xml \
  -testPlatform EditMode

exit codeが成功時は0/失敗時はそれ以外になるようだけど、unity cliはたまにバグって信用ならないので、xmlも見るのが吉.

成功
