Legacy PawnScript Project: Anti-AFK Captcha System

⚠️ Historical Note: This repository contains code developed entirely by me when I was 16 years old. It represents my beginnings in programming logic and server scripting (SA-MP), long before the rise of generative AI. It is shared to document my early problem-solving skills and my ability to design complex systems at a young age.

Project Context

At the time, many online gaming communities (specifically SA-MP servers) faced a major challenge: users utilizing automation tools (bots) to farm in-game rewards by leaving their characters working for long periods of time.

By observing the behavior of major servers from a player's perspective, I decided to replicate and develop from scratch a functional human verification system (Captcha). At just 16, I achieved this through functional reverse engineering, without access to any external source code or proprietary implementations.

Technical Challenges Overcome

• Functional Reverse Engineering: Replicating complex user-end logic and server-side validation flows based solely on external observation.
• Verification Logic: Implementing a robust flow where the system detects task completion and withholds rewards until a successful real-time validation is performed.
• Dynamic UI/UX: Utilizing TextDraws and Dialogs to create interactive interfaces that force human input before processing server-side variables.
• State Management: Controlling player states (freezing movement and blocking commands) to ensure the integrity of the verification process.

What This Project Demonstrates

1. Analytical Thinking: Identifying a systemic problem (inflation/automation) and crafting a technical solution to mitigate it.
2. Event-Driven Architecture: A deep understanding of how to handle requests, timers, and callbacks in a high-concurrency multiplayer environment.
3. Foundation & Evolution: It showcases the logical mindset and persistence I possessed as a teenager, which served as the foundation for my professional career.
