Describe a kind of thing once, then create individual objects that carry their own data and behavior.
A blueprint describes what a kind of object should know and what it should be able to do.
An object is one actual instance made from that blueprint. Two Player objects can follow the same blueprint but have different names and scores.
The blueprint defines the data. Then we create one Player object and give it values.
BLUEPRINT Player
CREATE name AS ""
CREATE score AS 0
END BLUEPRINT
CREATE Player AS playerOne
CHANGE playerOne.name TO "Brian"
CHANGE playerOne.score TO 10
SHOW playerOne.name
SHOW playerOne.scorePython classes commonly initialize each object inside __init__.
class Player:
def __init__(self):
self.name = ""
self.score = 0
playerOne = Player()
playerOne.name = "Brian"
playerOne.score = 10
print(playerOne.name)
print(playerOne.score)JavaScript uses class and constructor for this style of object.
class Player {
constructor() {
this.name = "";
this.score = 0;
}
}
const playerOne = new Player();
playerOne.name = "Brian";
playerOne.score = 10;
console.log(playerOne.name);
console.log(playerOne.score);C# properties define the data each Player object can hold.
class Player
{
public string Name { get; set; } = "";
public int Score { get; set; } = 0;
}
Player playerOne = new Player();
playerOne.Name = "Brian";
playerOne.Score = 10;
Console.WriteLine(playerOne.Name);
Console.WriteLine(playerOne.Score);Java fields can store the same name and score values on each Player object.
class Player {
String name = "";
int score = 0;
}
Player playerOne = new Player();
playerOne.name = "Brian";
playerOne.score = 10;
System.out.println(playerOne.name);
System.out.println(playerOne.score);C++ classes can expose data members that belong to each object.
class Player
{
public:
std::string name = "";
int score = 0;
};
Player playerOne;
playerOne.name = "Brian";
playerOne.score = 10;
std::cout << playerOne.name << '\n';
std::cout << playerOne.score << '\n';
