Learn to add and order scenes in Build Settings.
Build Settings and Scenes In Build
Which scenes are packaged into the final game executable and loadable through code is configured in File -> Build Settings. Scenes absent from the Scenes In Build list are omitted from the compiled project and cannot be accessed at runtime.
// Scene index and build list
// File -> Build Settings -> Add Open ScenesThe Add Open Scenes button quickly registers whichever scene is currently open in the editor into this list.
Build Index and Startup Scene
Each scene in the Scenes In Build list receives an integer (Build Index) starting from 0. The scene placed at the very top with index 0 automatically serves as the initial scene when the game launches.
// Scene at index 0 is the entry scene
// Index 0 -> MainMenu.unity
// Index 1 -> Level1.unityTypically, main menus or intro logos are placed at index 0 to kickstart the gameplay flow.
Practice Print scene index and name
Assign 0 to sceneIndex and "MainMenu" to sceneName. Print Index: 0 | Scene: MainMenu to the console.
Starter code
using System;
class Program
{
static void Main()
{
// sceneIndex ve sceneName değerlerini tanımlayıp yazdır
}
}Sample solution
using System;
class Program
{
static void Main()
{
int sceneIndex = 0;
string sceneName = "MainMenu";
Console.WriteLine("Index: " + sceneIndex + " | Scene: " + sceneName);
}
}Expected output
Index: 0 | Scene: MainMenu
