Interactions Between Objects
Explore how objects interact in C++ by using memory references to modify real data. Learn to build a battle simulator where players attack, heal, and perform special moves with realistic effects. Understand pass-by-reference, random damage, and dynamic turn-based interactions to simulate a game environment.
The project
In the previous lesson, you designed a Player class complete with fields like name, health, and attackPower, plus a method to display player stats and perform a basic attack.
That was a huge step! You successfully made one object affect another.
Now, it’s time to take that foundation further.
You’ll learn how and why objects interact the way they do in memory, and then you’ll simulate a real battle loop where two players continuously attack each other until one wins. This is where your simulator truly becomes a game—where code isn’t just static, but dynamic and alive.
The programming concept
The primary concept for this lesson is the interaction between objects—when one object utilizes another’s data or methods to produce an outcome. In C++, this happens through memory references. When you pass one object into another’s function (like attack(Player &target)), you aren’t sending a copy—you’re passing a reference to the same memory location.
This allows both objects to share and modify real data during the program’s execution.
