Implementing the Visitor Pattern in Game Engines with C++

The Visitor Pattern is a design pattern that allows you to separate an algorithm from the objects on which it operates. This is particularly useful in game engines for handling various types of game objects in a flexible manner without modifying their classes.

        // Visitor interface
        class IVisitor {
        public:
            virtual void visit(class Player& player) = 0;
            virtual void visit(class Enemy& enemy) = 0;
        };

        // Game objects
        class GameObject {
        public:
            virtual void accept(IVisitor& visitor) = 0;
        };

        class Player : public GameObject {
        public:
            void accept(IVisitor& visitor) override {
                visitor.visit(*this);
            }
        };

        class Enemy : public GameObject {
        public:
            void accept(IVisitor& visitor) override {
                visitor.visit(*this);
            }
        };

        // Concrete Visitor
        class DamageCalculator : public IVisitor {
        public:
            void visit(Player& player) override {
                // Calculate damage for player
                std::cout << "Calculating damage for player" << std::endl;
            }

            void visit(Enemy& enemy) override {
                // Calculate damage for enemy
                std::cout << "Calculating damage for enemy" << std::endl;
            }
        };

        // Usage
        int main() {
            Player player;
            Enemy enemy;
            DamageCalculator damageCalculator;

            player.accept(damageCalculator);
            enemy.accept(damageCalculator);

            return 0;
        }
