🎮 Game
Road Tool is a spline-based authoring and runtime library for roads, rails, intersections, parking lots, and traffic. In the editor it builds meshes for road surfaces, sidewalks, lines, bridges, rails, and decals, adapts terrain, and spawns helper prefabs like lampposts and crosswalks. At runtime it builds a lane graph and streams NPC vehicles and pedestrians, with a simple demo car controller and AI TrafficVehicle that can drive physics or kinematic cars.
🔧 Editor
An editor extension that lets creators place and edit road splines and intersections, and align or paint terrain around them. It adds EditorTools and an overlay window with gizmos for spline points and tangents, creation buttons for roads and intersections, and sidebar panels for terrain apply and paint with undo support. Selection changes propagate to the window, which draws handles and manages insert, move, and delete actions on spline points.
