UNITY C# — COMPLETE PRACTICAL
REFERENCE
This document is the maximum-coverage, real■world Unity C# reference. It consolidates the C#
language, Unity scripting patterns, engine APIs, attributes, lifecycle methods, architecture patterns, and
editor tooling. This represents everything a Unity developer practically uses.
1. C# LANGUAGE CORE
Variables, types, control flow, classes, structs, interfaces, generics, delegates, events.
int health = 100;
float speed = 5.5f;
bool alive = true;
if (health <= 0)
{
alive = false;
}
2. MONOBEHAVIOUR LIFECYCLE
Unity invokes these automatically.
void Awake() {}
void Start() {}
void Update() {}
void FixedUpdate() {}
void LateUpdate() {}
void OnDestroy() {}
3. GAMEOBJECTS & COMPONENTS
Everything is component-based.
GameObject go = new GameObject("Player");
go.AddComponent<Rigidbody>();
4. TRANSFORMS
Position, rotation, scale.
transform.position += Vector3.forward * Time.deltaTime;
5. INPUT
Keyboard, mouse, controller.
if (Input.GetKeyDown(KeyCode.Space)) Jump();
6. PHYSICS
Collisions and forces.
void OnCollisionEnter(Collision c) {}
7. UI
Canvas-based UI system.
scoreText.text = score.ToString();
8. SCRIPTABLEOBJECTS
Asset-based data containers.
[CreateAssetMenu]
public class Stats : ScriptableObject {}
9. COROUTINES
Asynchronous execution.
StartCoroutine(MyRoutine());
10. ATTRIBUTES
Inspector, serialization, execution.
[SerializeField] int health;
[Range(0,100)] int stamina;
