Mobile Pedestrian System

About Mobile Pedestrian System – Unity Editor Tool & Plugin

Unity Pedestrian System and Pedestrian AI

Mobile Pedestrian System provides pedestrian AI for Unity with grid pooling, waypoint pathfinding, obstacle avoidance, pedestrian zone restrictions, and traffic-light-aware street crossings. It can manage pedestrian density around the player, route individual characters to destinations, and connect crossing logic with vehicle systems, while requiring no coding for the initial setup.

Pedestrian Navigation and Crowd Behaviour

The system uses a waypoint-based navigation network with shortest-path calculation, direct route assignment, and destination routing. Priority waypoints let you influence where pedestrian density is concentrated, while decision-making allows pedestrians to choose when to cross, wait, or navigate around obstacles. Grid pooling dynamically manages pedestrians around the player, and additive scene loading supports open-world environments.

• Dynamic obstacle avoidance around fixed environment assets and moving objects.
• Custom pedestrian types with zone and access restrictions.
• Custom behaviours that can add AI logic without changing the core system code.
• Custom waypoint events for triggering gameplay logic when a pedestrian reaches a designated waypoint.

Crosswalks and Traffic Systems

Crossings support both traffic-light-controlled and non-signaled streets. An independent crossing component can be used with custom vehicle systems, while Mobile Traffic System integration synchronizes pedestrian crossings with vehicle yielding and traffic-light coordination.

Characters and Animation

Pedestrians support any humanoid rig or character model and use Apply Root Motion from the character Animator for movement. The package includes Die, Idle, Revive, Run, and Walk animations from Unity's character example. The supplied configuration uses a blend tree with a turn animation and a walk animation, while other animations and behaviours can also be integrated.

Performance and Editor Workflow

The technical architecture uses a parallel job system driven by the Unity Burst Compiler, together with pooling and layer management. A Waypoint editor assists with semi-automatic waypoint generation, while custom editor windows provide setup automation. The package includes complete commented source code with no DLLs.

Unity 2021.3 LTS or above is required, with compatibility for Unity 6. The system supports the Built-in Render Pipeline, URP, and HDRP, and works on platforms that support the Burst Compiler.

Included Content

• 1 production-ready pedestrian.
• 1 mobile production-ready car with 3 LODs and changeable colors.
• 9 road tiles for assembling complex road layouts.
• 20 simple city buildings for environment population.
• 1 demo scene combining the included content.

Use Cases

• City and open-world projects that need pooled pedestrians distributed across waypoint networks.
• Driving environments where pedestrians and vehicle traffic need coordinated crosswalk behaviour.
• Games using custom humanoid characters and root-motion animation controllers.
• Urban scenes requiring pedestrian groups to follow different area restrictions or trigger scripted events at specific locations.
