DOTS Traffic Core

DOTS Traffic Core is a powerful tool for creating city traffic - Design it from the ground up or customise any existing asset pack to fit your vision!

It uses the extremely powerful DOTS Entities package to simulate thousands of vehicles with unbelievable performance!

Seamlessly integrates into classic workflows: fully compatible with your standard MonoBehaviour and GameObject-based systems.

• Mobile friendly
  Simulate thousands of interacting vehicles and pedestrians, even on mobile devices.
• Performance
  Experience the performance firsthand in our various platform-specific demo projects or just check out the final screenshots to see the results.
• Rapid integrationIntegrate any city asset pack in a heartbeat with our convenient templates and tools.
• SimulationSimulate thousands of entities without relying on physics or raycasting (although physics simulation is also available).
• Monobehaviour support
  Not familiar with DOTS? No problem! The project is fully compatible with MonoBehaviour scripts in hybrid mono mode (check out the Hybrid Mono sample scene).
• EditorMany flexible tools to bring life to the city of your dreams.
• Demo
  Demo sample scene included!
• Sound
  Integration of the FMOD sound engine into bursted jobs (the built-in Unity audio engine is also supported).
• Documentation
  All components of DOTS Traffic Core are linked to online documentation.
• Source codeAll code included.
• Vehicle controllerDOTS physics vehicle controller included!
• You can also use Edy's, RCC or NWH & other custom vehicle controllers for both player and traffic.
• Modular architecture
  Allows you to integrate the project into your existing game without hassles.
• Netcode For Entities
  A new demo scene showcases a network solution based on pure DOTS.
• A* navigation
  Set to follow a car to a given node using the built-in A* pathing.
• Upgrade
  The tool can be upgraded to DOTS Traffic City.

Key features:

🚗 Traffic

• Physics
  Vehicles can use either:
• Simple physics.
• Custom physics (custom physics controller included).
• Hybrid mono physics.
  Any monobehaviour controller can be integrated into the traffic.
• No physics.
• Trailers
  Support for vehicles with trailers (supported for both DOTS Entities and Hybrid Mono).
• Motorcycles & 3-Wheelers
  Support for two-wheeled bikes and three-wheeled vehicles (supported for Hybrid Mono mode only).
• Speed controlAutomatic vehicle speed control depending on lane speed limit, traffic lights and other traffic.
• Lane changingAutomatic vehicle lane changing based on traffic congestion or road type, including overtaking via the oncoming lane when safe and permitted.
• Traffic groupsRestrict lanes to certain traffic group types.
• Fast creationQuick and easy tool for adding any vehicle into the city.
• AvoidanceThe avoidance system makes sure that vehicles don’t collide with each other and will stop and move away if another vehicle is blocking their path.
• Obstacle AvoidanceBypassing a player or specified custom obstacles.
• Driving stylesThere are different types of driving styles on the road: considerate, passive, and aggressive.
• PriorityVehicles pass through the intersections according to road priority.
• Emergency vehiclesSupport for AI and player-controlled priority vehicles (police, ambulances, etc.) with dynamic traffic avoidance (yielding, pulling over, lane changing).
• AntistuckAn Antistuck system that automatically despawns the entity if it gets stuck for a while and isn't visible in the player's camera.
• Traffic JamsGridlock prevention: Vehicles hold before intersections if the exit lane is blocked.
• Custom PathAllows vehicles to navigate directly to target nodes via A* pathing.
• Left-hand traffic
  Starting with version 1.1.0, driving on the left is available.
• CullingVehicles only spawn around the player.
• Combined physicsLimit physics to only the vehicles closest to the player in order to improve performance.
• LODsLOD system for the vehicles depending on the distance to the camera.
• TestsA handy traffic test scene where most traffic situations can be tested with all available parameters.

🏙️ City

• Traffic roadMultiple road templates and custom road customization tools.
• Road APIGenerate road segments from raw data or unity splines.
• CullingAll entities in the city change their behaviour depending on the culling state (including traffic).
• Physics cullingOnly the physics objects close to the player are involved in the physics evaluation.
• Traffic lightQuick and easy creation of traffic lights. Automatically connect hundreds of traffic lights across your entire city in just one click.
• DebugConvenient visualisation of data on scene.

🛠️ Tools

• Road segment creatorA Tool containing the 10 most commonly used road templates, allowing you to quickly and easily set waypoints and route settings of any complexity.
• Auto-crossroad generationNew option to create crossroads with a single click.
• Car prefab creatorA Tool that quickly converts 3D models of vehicles to traffic entities in just a few clicks.
• Global traffic light settingsA tool to connect traffic lights and traffic nodes, crossroads, and visually display the timings of each traffic light on the scene.
