In this tutorial, we build on the procedural road network and vehicle AI system, enhancing its functionality and efficiency. You’ll learn how to adjust the first and last path nodes to refine primary vehicle path, ensure vehicle stay on the right side of the road, and implement advanced spatial queries using a Quadtree for more efficient pathfinding. We also cover how to find splines within a specific area to improve the system’s efficiency. Lastly, we guide you through fixing any packaging issues to ensure your project is ready for deployment.
