Major Differences Between C# and Unity JavaScript - Unity 4 Game Development - page 635

// JavaScript user:
class MyClass {
var myVar = 1;
function MyClass() {
Debug.Log("Hello World!");
}
}
// C# user:
class MyClass {
public int myVar = 1;
void MyClass() {
Debug.Log("Hello World!");
}
}
Note
If you are inheriting from MonoBehaviour , you should not use constructors or de-
structors. Instead, use the event handler functions such as Start() , Awake() , and
OnEnabled() .
