Composition over Inheritance

Short summary

A C++ developer reflects on switching from inheritance-based class hierarchies to composition patterns while building a game. The author demonstrates how multiple powerup classes share identical constructor patterns and behavior logic, suggesting deeper design issues. The post hints at how composition could eliminate unnecessary inheritance layers.

• •Inheritance created deeply-nested class hierarchies (Fallable → PowerUp → PUdoubleBar, etc.)
• •All powerup subclasses repeat nearly identical constructors and two core methods
• •Composition pattern could simplify the design and eliminate inheritance overhead
