Anti cheat tricks - Variable offset

Eine kleine Klasse die zeigt wie manche Developer Werte in ihren Games obfuskieren um Memory-Editing zu verhindern.

Diese Technik fügt einen zufälligen Offset zu gespeicherten Werten hinzu, was sie schwerer in Memory-Scannern zu finden und zu modifizieren macht.

#include <iostream>
template<typename T>
class OffsetVariable {
private:
  T value;
  int offset;
public:
  explicit OffsetVariable(T initial) {
    offset = 1337; // Generate a random number here
    value = initial + offset;
  }
  T get() {
    return value - offset;
  }
  void set(T v) {
    value = v + offset;
  }
};
int main() {
  OffsetVariable<int> health(100);
  OffsetVariable<float> mana(100);
  std::cout << "Player health: " << health.get() << std::endl;
  std::cout << "Player mana: " << mana.get() << std::endl;
  health.set(50);
  mana.set(25);
  std::cout << "Player health: " << health.get() << std::endl;
  std::cout << "Player mana: " << mana.get() << std::endl;
  return 0;
}
