Class Declaration

Classes in Morph define objects with fields and methods.

---

Basic Syntax

Player class {
    name is "Unknown" as string;
    health is 100 as int;
}

Convention: Omit is for class declarations (it's optional).

---

With is (Also Valid)

Player is class {
    name is "Unknown" as string;
}

Both forms compile identically. Omitting is is the recommended style.

---

One Class Per File

Morph enforces a strict one-class-per-file rule. The class name must match the filename:

File	Class Name
Player.mx	Player class { }
Vector2.mx	Vector2 class { }
Main.mx	Contains Init method (no class required)

This is enforced by the compiler when max_classes_per_file = 1 in .morphsettings.

---

Creating Instances

Call the class name as a function:

p is Player();
Print(p.name);     // "Unknown"
Print(p.health);   // 100

---

Access Modifier on Class

Player public class {
    // visible outside this module
}

---

Generic Classes

Classes can accept type parameters:

Box class<T> {
    value is T;
}

b is Box<int>();
b.value is 42;

See Generic Classes.
