PC/Mac standalone build in Unity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a standalone build in Unity?

A standalone build is a version of your Unity project compiled to run independently on a specific platform like PC or Mac, without needing the Unity Editor.

beginner

Which Unity menu do you use to create a PC or Mac standalone build?

You use the File > Build Settings menu to open the build window and select PC or Mac as the target platform.

beginner

What file formats are common for PC and Mac standalone builds in Unity?

For PC, the build creates an .exe file with a _Data folder. For Mac, it creates an .app bundle folder.

intermediate

Why should you test your standalone build on the target platform?

Because some features or performance can differ outside the Unity Editor, testing ensures your game runs correctly on the actual PC or Mac system.

beginner

How do you switch the build target to Mac in Unity?

In Build Settings, select Mac OS X as the platform and click Switch Platform. This prepares Unity to build for Mac.

Which menu option in Unity lets you start building a PC or Mac standalone game?

A File > Build Settings

B Edit > Preferences

C Window > Package Manager

D Assets > Import Package

The Build Settings menu under File is where you select platforms and start the build process.

What file extension does a Windows standalone build usually have?

A .app

B .dmg

C .apk

D .exe

Windows standalone builds create an executable file with the .exe extension.

What must you do before building for Mac in Unity?

A Enable VR support

B Install Android SDK

C Switch platform to Mac OS X in Build Settings

D Change scripting backend to IL2CPP

You must switch the build target platform to Mac OS X before building for Mac.

Why is testing your standalone build important?

A To verify the game runs correctly on the target OS

B To update Unity to the latest version

C To check if the Unity Editor is installed

D To reduce the build file size

Testing ensures your game works properly on the actual PC or Mac outside the editor.

What folder usually accompanies the .exe file in a Windows standalone build?

A Assets folder

B _Data folder

C Scripts folder

D Plugins folder

The _Data folder contains game data and is required alongside the .exe file.

Describe the steps to create a PC standalone build in Unity.

Think about menus, platform selection, and output files.

Explain why switching the build platform in Unity is necessary before building for Mac or PC.

Consider how different computers run programs.

Practice

1. What is the main purpose of creating a PC/Mac standalone build in Unity?

easy

A. To create a separate app that can run outside the Unity editor

B. To edit game scripts directly in Unity

C. To test game performance inside the Unity editor

D. To upload the game directly to the Unity Asset Store

Solution

1. Step 1: Understand what a standalone build is

   A standalone build is a version of your game that runs independently from the Unity editor.

2. Step 2: Identify the purpose of the build

   This build lets players run the game as a normal app on PC or Mac without needing Unity.

3. Final Answer:

   To create a separate app that can run outside the Unity editor -> Option A

4. Quick Check:

   Standalone build = separate app outside Unity [OK]

Hint: Standalone builds run games outside Unity editor [OK]

Common Mistakes:

• Confusing builds with editing scripts
• Thinking builds only test performance inside Unity
• Believing builds upload games to Asset Store

2. Which Unity menu option do you use to start creating a PC/Mac standalone build?

easy

A. File > Build Settings

B. Edit > Preferences

C. Window > Package Manager

D. Assets > Import Package

Solution

1. Step 1: Recall where build options are located

   Unity places build options under the File menu in the Build Settings window.

2. Step 2: Confirm the correct menu path

   File > Build Settings is the correct path to select platform and build the game.

3. Final Answer:

   File > Build Settings -> Option A

4. Quick Check:

   Build Settings menu = File > Build Settings [OK]

Hint: Build Settings is always under File menu [OK]

Common Mistakes:

• Choosing Edit > Preferences which is for editor settings
• Selecting Window > Package Manager which manages packages
• Using Assets > Import Package which imports assets

3. Given this code snippet in Unity, what will happen when you build and run the PC/Mac standalone build?

void Start() {
    Debug.Log("Game started");
}

medium

A. The message "Game started" will appear in the standalone build's console window

B. The message "Game started" will appear in the Unity editor console only

C. The game will crash because Debug.Log is not supported in builds

D. Nothing will happen because Start() is not called in builds

Solution

1. Step 1: Understand Debug.Log behavior in builds

   Debug.Log messages appear in the Unity editor console but are not shown in the standalone build by default.

2. Step 2: Confirm what happens when running the build

   The standalone build runs the Start() method, but its console output is not visible to the user.

3. Final Answer:

   The message "Game started" will appear in the Unity editor console only -> Option B

4. Quick Check:

   Debug.Log visible in editor console, not in build [OK]

Hint: Debug.Log shows only in editor console by default [OK]

Common Mistakes:

• Thinking Debug.Log messages appear in standalone build window
• Believing Debug.Log causes crashes in builds
• Assuming Start() is not called in builds

4. You created a PC standalone build, but when you run it, the game window stays black and does not respond. What is the most likely cause?

medium

A. Your computer does not support Unity editor

B. You did not save the project before building

C. You forgot to add scenes to the Build Settings Scenes In Build list

D. You used Debug.Log in your scripts

Solution

1. Step 1: Identify common build issues

   If no scenes are added to the Build Settings, the build has no content to show, resulting in a black screen.

2. Step 2: Eliminate other options

   Not saving project does not cause black screen; computer support for editor is unrelated; Debug.Log does not cause black screen.

3. Final Answer:

   You forgot to add scenes to the Build Settings Scenes In Build list -> Option C

4. Quick Check:

   Missing scenes in build = black screen [OK]

Hint: Always add scenes to Build Settings before building [OK]

Common Mistakes:

• Assuming saving project fixes black screen
• Thinking computer must run Unity editor to run build
• Blaming Debug.Log for black screen

5. You want to create a PC standalone build that runs only in fullscreen mode and uses a specific resolution of 1920x1080. Which code snippet should you add to your game to enforce this when the build starts?

hard

A. void Update() { Screen.SetResolution(1920, 1080, false); }

B. void Start() { Application.fullScreen = false; Screen.SetResolution(1920, 1080, false); }

C. void Awake() { Screen.fullScreenMode = FullScreenMode.Windowed; }

D. void Start() { Screen.SetResolution(1920, 1080, true); }

Solution

1. Step 1: Understand how to set resolution and fullscreen

   Screen.SetResolution(width, height, fullscreen) sets resolution and fullscreen mode at runtime.

2. Step 2: Choose the correct method and parameters

   void Start() { Screen.SetResolution(1920, 1080, true); } sets 1920x1080 resolution and enables fullscreen in Start(), which runs once at game start.

3. Step 3: Eliminate incorrect options

   void Start() { Application.fullScreen = false; Screen.SetResolution(1920, 1080, false); } disables fullscreen; void Awake() { Screen.fullScreenMode = FullScreenMode.Windowed; } sets windowed mode; void Update() { Screen.SetResolution(1920, 1080, false); } sets resolution every frame, which is inefficient.

4. Final Answer:

   void Start() { Screen.SetResolution(1920, 1080, true); } -> Option D

5. Quick Check:

   SetResolution with fullscreen true in Start() [OK]

Hint: Use Screen.SetResolution(width, height, true) in Start() [OK]

Common Mistakes:

• Setting fullscreen false by mistake
• Changing resolution every frame in Update()
• Using wrong fullscreen mode property
