Battleship Engine: Legacy Refactoring & Object-Oriented System Design in C++

High-performance computing requires a deep understanding of memory management, hardware interaction, and low-level architecture. To demonstrate our foundational engineering capabilities, we undertook the complete architectural refactoring of the Battleship Engine, transitioning a legacy procedural C++ codebase into a robust, Object-Oriented system powered by the Allegro framework.

The original deployment interface (shown below) was maintained while the entire underlying logic was rewritten for maximum efficiency.

The Problem: The Cost of Spaghetti Code and Technical Debt

The initial iteration of this software was built under extreme constraints—developed in under 48 hours without proper software engineering modeling. The result was a monolithic “spaghetti code” structure. While functional, it lacked scalability, maintainability, and testing capabilities. In enterprise environments, this type of technical debt is a severe liability that prevents feature expansion and causes system crashes.

The Solution: Complete Architectural Redesign

Rather than applying superficial patches, we executed a full software engineering lifecycle process to rescue the codebase. We stripped the procedural logic and designed a strict Object-Oriented Architecture.

  • Separation of Concerns (MVC-Inspired): As seen in the structural class diagram below, we isolated the BattleshipGameEngine from the View interfaces. This decoupling ensures that the core game logic (ships, states, grids) is completely independent of the graphical rendering engine (Allegro 4.4.3), making the system modular and highly testable.
  • Behavioral Flow Optimization: We modeled the entire system behavior to ensure predictable state management. As the activity diagram illustrates, the flow handles complex branching—from AI opponent logic to sequential turn processing and event-driven mouse/keyboard inputs—without blocking the main execution thread.
  • AI Implementation: We integrated an algorithmic opponent capable of strategic decision-making (random searching combined with proximity-based targeting once a hit is confirmed), proving capabilities in state-tracking and logic algorithms.

The Impact

The Battleship Engine project stands as a testament to the value of proper software design. By conquering massive technical debt and applying strict OOP principles in C++, we transformed a fragile script into a scalable, high-performance software architecture. It showcases our ability to not just write code, but to rescue, refactor, and architect systems that are built to last.

The Architecture Behind the Build Complex integrations require a clear vision. The underlying architecture and core development of Battleship Engine were spearheaded by our Solutions Architect, Israel Villaroel, ensuring the system wasn’t just intelligent, but built to scale and deploy seamlessly into real-world enterprise environments.

What does your system engineering and consulting involve?

Before writing code, we start with a deep technical diagnosis. We analyze your entire infrastructure, software, and daily operations to identify risks and real opportunities for system improvement.

Based on the initial diagnosis, we design a clear architecture and a realistic technical roadmap. Every single decision considers stability, scalability, and compatibility with your ongoing operations. We never apply generic fixes to complex tech systems.

Finally, we execute structural changes in a controlled and documented manner, strictly aligned with your internal teams. Execution is just a part of the process, not the end. We provide continuous tech support to ensure full platform adoption, smooth continuity, and the absolute capacity for future evolution.

We focus on the complexity of your systems rather than just the size of your company. We partner with organizations that already have running operations but face technical limits due to fast growth.

Often, companies scale their operations rapidly without establishing a solid technical architecture. They end up dealing with accumulated technical debt, unscalable software, or critical infrastructure that is simply too difficult and costly to maintain.

Whether you are a mid-sized team or a large enterprise, our tech interventions are always progressive and highly conscious. We deeply respect your ongoing processes and existing teams. Our main objective is to enable true technical evolution without ever putting your daily operational continuity at risk.

Yes, we frequently intervene in existing platforms that suffer from accumulated technical debt.

Before any intervention, we completely analyze the entire system: your infrastructure, software, and processes. This allows us to spot operational risks and find the safest path to refactor your tech debts.

Our interventions are always progressive and highly conscious. We redesign the architecture and implement structural improvements without ever risking your daily operational continuity.

We never rely on generic tools. Our tech stack is chosen based on your specific system needs. We utilize cloud infrastructure, robust software frameworks, and automated deployments to ensure solid stability.

We build robust backend architectures with Python and Laravel, and scalable applications using React Native. Our cloud infrastructure is strictly powered by Docker, Kubernetes, and GCP to ensure high availability.

For complex data and AI, we leverage TensorFlow and NLP models. Every tool is implemented with strict operational control and continuous support.

Yes, we do. In codesPACT, execution is merely a part of the process, not the end. We provide continuous tech support to ensure your systems evolve with absolute stability, proper control, and a clear technical direction long after the initial deployment phases.

We accompany the transition to assure full adoption, continuity, and future evolution capacity. We do not just deliver the system; we make sure that your internal teams operate it securely.

This approach allows real improvements without generating unnecessary dependencies. Our ongoing role is to act as your technical partner for strategic decisions.
