Developed an extensibility enhancement for the Qbox-project/qbx_core repository by implementing a server-side Paycheck Event Hook, enabling third-party integrations to respond to paycheck events without altering the core configuration. Leveraging event-driven architecture and Lua, this feature introduced the qbx_core:server:onPaycheck event, which is triggered after each successful paycheck distribution. The event payload was designed to align with existing conventions, ensuring consistency within the current eventing model. This approach established a standardized integration point for external resources, streamlining partner integration and reducing friction. The work focused on game server development, prioritizing maintainability and future extensibility through a modular, event-based solution.
