What is the output of this Unity build script snippet?

Consider this C# script snippet used in Unity Editor to build a standalone PC/Mac application. What will be the output in the console after running this method?

Unity

using UnityEditor;
using UnityEngine;

public class BuildScript {
    public static void BuildGame() {
        string path = "Builds/MyGame.exe";
        BuildPlayerOptions buildPlayerOptions = new BuildPlayerOptions();
        buildPlayerOptions.scenes = new[] {"Assets/Scenes/Main.unity"};
        buildPlayerOptions.locationPathName = path;
        buildPlayerOptions.target = BuildTarget.StandaloneWindows64;
        buildPlayerOptions.options = BuildOptions.None;

        var report = BuildPipeline.BuildPlayer(buildPlayerOptions);
        if (report.summary.result == UnityEditor.Build.Reporting.BuildResult.Succeeded) {
            Debug.Log("Build succeeded: " + report.summary.totalSize + " bytes");
        } else {
            Debug.Log("Build failed");
        }
    }
}

A Build succeeded: 0 bytes

B Build failed

C Build succeeded: [some positive number] bytes

D Compilation error due to missing using directive

💡 Hint

Think about what BuildPipeline.BuildPlayer returns and what the summary.totalSize represents.

The BuildPipeline.BuildPlayer method returns a BuildReport object. If the build succeeds, the summary.result is Succeeded and totalSize is the size of the built player in bytes, which is a positive number. So the output will be "Build succeeded: [some positive number] bytes".

Which build target should you choose for a Mac standalone build in Unity?

You want to create a standalone build for Mac OS using Unity. Which BuildTarget enum value should you use?

A BuildTarget.StandaloneWindows64

B BuildTarget.WebGL

C BuildTarget.iOS

D BuildTarget.StandaloneOSX

💡 Hint

Mac standalone builds require a specific target for Mac OS.

For Mac standalone builds, Unity uses BuildTarget.StandaloneOSX. Windows builds use StandaloneWindows64. iOS and WebGL are for different platforms.

Why does this PC build fail with 'Missing scenes' error?

Look at this build script snippet. The build fails with an error about missing scenes. What is the cause?

Unity

BuildPlayerOptions options = new BuildPlayerOptions();
options.scenes = new string[] {"Assets/Scenes/Level1.unity", "Assets/Scenes/Level2.unity"};
options.locationPathName = "Builds/MyGame.exe";
options.target = BuildTarget.StandaloneWindows64;
BuildPipeline.BuildPlayer(options);

A The scene paths are incorrect or scenes are not added to the build settings

B The locationPathName must end with .app for Windows builds

C BuildTarget.StandaloneWindows64 is deprecated and causes errors

D BuildPipeline.BuildPlayer requires a callback parameter

💡 Hint

Check if the scenes are included in the Unity build settings and if the paths are correct.

Unity requires scenes to be added to the build settings or referenced correctly. If the scene paths are wrong or not included in build settings, the build fails with missing scenes error.

Which option correctly sets the build location for a Mac standalone build?

Choose the correct way to set the build output path for a Mac standalone build in Unity.

A options.locationPathName = "Builds/MyGame.app";

B options.locationPathName = "Builds/MyGame.exe";

C options.locationPathName = "Builds/MyGame";

D options.locationPathName = "Builds/MyGame.dmg";

💡 Hint

Mac standalone builds produce an application bundle with a specific extension.

Mac standalone builds produce an application bundle with the .app extension. Using .exe is for Windows, and .dmg is a disk image, not the build output.

How many scenes will be included in this PC build?

Given this build script snippet, how many scenes will be included in the final build?

Unity

string[] scenes = new string[] {
    "Assets/Scenes/Main.unity",
    "Assets/Scenes/Intro.unity",
    "Assets/Scenes/Level1.unity"
};

BuildPlayerOptions options = new BuildPlayerOptions();
options.scenes = scenes;
options.locationPathName = "Builds/GameBuild.exe";
options.target = BuildTarget.StandaloneWindows64;
BuildPipeline.BuildPlayer(options);

A 0

B 3

C 1

D Depends on build settings scenes

💡 Hint

When you specify scenes explicitly in BuildPlayerOptions, those scenes are included regardless of build settings.

When you provide the scenes array explicitly in BuildPlayerOptions, Unity includes exactly those scenes in the build, ignoring the build settings scenes list.
