 === C# Basics ===
-> **Classes and Structures**
-One of the basic design decisions every framework designer faces is whether to design a type as a **class (a reference type)** or as a **struct (a value type)**.
-**Similarities:**
-  * Both are _container_ types, meaning that they contain other types as members.
-  * Both have members, which can include constructors, methods, properties, fields, constants, enumerations, events, and event handlers.
-  * Members of both can have individualized access levels. For example, one member can be declared `Public` and another `Private`.
-  * Both can implement interfaces.
-  * Both can have shared constructors, with or without parameters.
-  * Both can expose a _default property_, provided that property takes at least one parameter.
-  * Both can declare and raise events, and both can declare delegates.
-**Differences:**
-The Main difference between reference types **(Class)** and value types **(Struct)** we will consider is that reference types are allocated on the heap and garbage-collected, whereas value types are allocated either on the stack or inline in containing types and deallocated when the stack unwinds or when their containing type gets deallocated.
-  * Structures are **_value types_**; classes are **_reference types_**. A variable of a structure type contains the structure's data, rather than containing a reference to the data as a class type does.
-  * Structures use stack allocation; classes use heap allocation.
-  * All structure elements are `Public` by default; class variables and constants are by `Private` default, while other class members are by `Public` default.
-  * A structure must have at least one nonshared variable or nonshared, noncustom event element; a class can be completely empty.
-  * Structure elements cannot be declared as `Protected`; class members can.
-  * Structures are not inheritable; classes are.
-  * A structure does not require a constructor; a class does.

+> **Variables and Parameters**
+Variables can be controlled from the Unity Editor as parameters, as long as they are defined public or serializable.
+We can use both simple variable or arrays.
+<code>
+public float speed;
+public Sprite[] images;
+private float internalBleed; //cannot be controller from Unity Editor interface
+[SerializeField]
+private Text scoreText;
+[SerializeField]
+private GameObject[] enemyTypes;

-Parametri se pot controla in editor atat timp cat sunt definiti ca variabile publice sau serializabile.

-<code>
-public float speed;
-public Sprite[] images;
-[SerializeField]
-private Text scoreText;
-[SerializeField]
-private GameObject[] enemyTypes;
-</code>
-=== Instantierea obiectelor ===
-Obiectele se pot instantia folosind functia
-<code>
-newobj = Instantiate(objTemplate) as ObjType;
-//from pregab - prefab must be in Resources folder
-newobj1 = Instantiate(Resources.Load("enemy"));
-// Instantiate the projectile at the position and rotation of this transform
-Rigidbody projectile;
-Rigidbody clone;
-clone = Instantiate(projectile, transform.position, transform.rotation);
-enemyOrc = Instantiate(Orc) as Enemy;
-</code>
-=== Transformari ===
-Transformarile unui obiect se pot accesa prin atributul `transform` (https://docs.unity3d.com/ScriptReference/Transform.html)
-<code>
-Vector3 objectPosition = GameObject.transform.position;
-GameObject.transform.position = new Vector3(posX, posY, posZ);
-transform.Translate(Vector3.up * Time.deltaTime, Space.World);
-transform.Rotate(Vector3.up * Time.deltaTime, Space.World);
-</code>
-=== Random ===
-Pentru a genera valori random puteti folosi clasa Random
-<code>
-Random.Range(-10.0f, 10.0f)
-Random.Range(0, 8);
-</code>
-=== Controlul unor obiecte sau componente ===
-Afisarea sau ascunderea unui obiect din scena se poate face prin functia de activare
-<code>
-myObject.SetActive(false); // ascunde
-myObject.SetActive(true); // arata
-</code>
-Similar, se pot controla componentele unui obiect
-<code>
-this.GetComponent<BoxCollider>().SetActive(false); // dezactivare
-this.GetComponent<SpriteRenderer>().sprite = image; //setarea unei imagini
-myObject.GetComponent<Text>().text = '123' //setarea unui text
-</code>
-De asemenea se pot accesa elemente copil sau parinte
-<code>
- childObject=parentObject.GetChild("child_name");
- //setarea unei componente a elementului copil
- parentObject.GetChild("child_name").GetComponent<SpriteRenderer>().sprite = image;
-</code>
-=== Asteptari/Wait  ===
-Daca vreti veti sa introduceti asteptari in rularea unui script/functii puteti folosi corutine.
-Corutinele sunt folosite pentru a porni functii asincrone, care se pot intinde pe mai multe frame-uri, si in care se poate pune pauza (wait).
-<code>
-void Start()
 {
-    StartCoroutine(Example());
+    // Destroy the gameObject after clicking on it
-}
+    Destroy(gameObject);
+}
-IEnumerator Example()
-{
-    print(Time.time);
-    yield return new WaitForSeconds(5);
-    print(Time.time);
-}
 </code>
-=== Evenimente de Input ===
-Pentru a putea detecta daca un element a fost apasat, se poate folosi functia OnMouseDown
+> **Debug**
-<code>
-void OnMouseDown()
+<code c#>
-{
+Debug.Log(transform.position);
-      gameObject.SetActive(false);
+Debug.Log("text");
-}
 </code>
-<note important>Atentie! Aceasta functie este activa doar in cazul in care utilizatorul apasa cu mouseul peste un elemente de UI sau un Collider</note>
