What is the Object-Oriented Programming (OOP) concepts in Scratch

 Certainly! Here is the explanation of Object-Oriented Programming (OOP) concepts in Scratch in English.

In Scratch, you are actually using OOP principles every time you create a project. Here is how the core concepts map to Scratch features:

---

1. Objects and Classes

In Scratch, "Sprites" are the primary objects.

• Sprite (Object): Think of a sprite as an object that bundles together data (costumes, sounds) and behaviors (scripts).

• Cloning (Instantiation): When you use the "create clone of..." block, you are creating an instance of that sprite. The original sprite acts like a Class (the blueprint), and each clone is an individual Object created from that blueprint.

2. Encapsulation

This is about grouping data and methods together and restricting access to the inner workings.

• "For this sprite only" Variables: These are Private Variables. Other sprites cannot directly change them, which protects the data from being messed up by outside scripts.

• My Blocks (Custom Blocks): These allow you to hide complex code inside a single block. You don't need to know how the block works every time you use it; you just need to know what it does.

3. Inheritance

Inheritance is when one object takes on the properties of another.

• Clones: When a clone is created, it inherits all the scripts, costumes, and current variable values of the parent sprite. It starts its life as a "child" with all the characteristics of the "parent."

4. Polymorphism

This means "many shapes." In programming, it refers to different objects responding to the same command in their own unique way.

• Broadcasting Messages: If you "Broadcast [Start Game]," the Cat sprite might say "Let's go!", while the Goal sprite might show itself. One single signal (the broadcast) triggers different behaviors depending on which sprite receives it.
