Learn to edit component values in the Inspector window.
Inspector window
The Inspector window displays all details of the item selected in the Hierarchy or Project panel. When a GameObject is selected, its name, tag, layer, and all attached components are listed here.
// Transform fields visible in Inspector:
// Position: (0, 0, 0)
// Rotation: (0, 0, 0)
// Scale: (1, 1, 1)Developers can edit numerical values of components directly through these fields in the window.
Inspector fields and SerializeField
In your C# scripts, public variables automatically appear as editable fields in the Inspector window. To keep a variable private yet expose it in the Inspector, use the [SerializeField] attribute.
public float speed = 5.0f;
[SerializeField] private int health = 100;This allows you to quickly test and balance gameplay mechanics from the Inspector without editing code.
Practice Print Inspector field values
Define speed (value 5.5) and health (value 100) representing two Inspector fields. Print Speed: 5.5 | Health: 100 to the console.
Starter code
using System;
class Program
{
static void Main()
{
// speed ve health alanlarını tanımlayıp yazdır
}
}Sample solution
using System;
class Program
{
static void Main()
{
double speed = 5.5;
int health = 100;
Console.WriteLine("Speed: " + speed + " | Health: " + health);
}
}Expected output
Speed: 5.5 | Health: 100

1 What happens to modifications made in the Inspector window while the game is running in Play mode?
- Unity automatically compiles the entire project from scratch.
- All components in the scene are instantly deleted.
- When exiting Play mode, values revert back to their pre-test state. Correct answer
- Changes are permanently saved to disk and cannot be undone.
Explanation: Inspector modifications during Play mode are temporary; they revert to original values when playback stops.
2 Expose private variable to Inspector
[____] private float jumpForce = 8.5f;[SerializeField] private float jumpForce = 8.5f;Explanation: The [SerializeField] attribute allows private fields to appear in Unity's Inspector panel.
