Imagine you create a game in Unity. Why should you consider deploying it on multiple platforms like Windows, Android, and iOS?
Think about how many different devices people use to play games.
Deploying on multiple platforms lets more people play your game, no matter what device they have. This increases your audience and potential success.
Consider this Unity C# code that checks the platform and prints a message:
using UnityEngine;
public class PlatformCheck : MonoBehaviour {
void Start() {
#if UNITY_ANDROID
Debug.Log("Running on Android");
#elif UNITY_IOS
Debug.Log("Running on iOS");
#else
Debug.Log("Running on another platform");
#endif
}
}If you run this on an Android device, what will be printed in the console?
Look at the platform symbols used in the preprocessor directives.
The code uses preprocessor directives to detect the platform at compile time. On Android, UNITY_ANDROID is defined, so it prints "Running on Android".
You have a Unity project that builds and runs fine on Windows. But when you try to build for iOS, it fails with errors related to file paths. What is the most likely cause?
Think about differences in file systems between Windows and iOS.
Windows uses backslashes (\) in file paths, but iOS uses forward slashes (/). Using Windows-style paths causes errors on iOS builds.
Choose the code that correctly detects if the game is running on Android during runtime.
Check the correct way to compare enums in C#.
Application.platform returns a RuntimePlatform enum. Comparing it to RuntimePlatform.Android is correct. Option A uses a compile-time symbol incorrectly. Option A compares enum to string. Option A reverses enum and variable.
You want to create a Unity game that works well on PC, mobile, and consoles. Which practice best supports smooth cross-platform deployment?
Think about how to write code that works everywhere without changes.
Using platform-independent APIs and avoiding hardcoded paths ensures your game runs on all platforms. Testing on devices helps catch platform-specific issues early.
