WAYPOINT PATH SYSTEM

Visual NavMesh route authoring for Unity

A production-focused path system that lets designers create and edit NPC routes directly in the Scene View, then drive individual agents or crowds through configurable paths without setup boilerplate.

01 · The problem

NPC paths are spatial. Their authoring should be too.

Route systems are often configured through long Inspector lists, disconnected scene objects, or project-specific scripts. That makes a spatial task slow to understand and easy to misconfigure.

I designed Waypoint Path System around direct manipulation: create the route where it exists, see useful measurements while editing, and keep detailed behavior available without burying the common workflow.

Place the route in the Scene View. See what the agent will do before pressing Play.

02 · My contribution

A complete authoring-to-runtime workflow.

Scene View tooling

Built click-to-place routes with insertion, reordering, labels, colors, snapping, shortcuts, live distance readouts, and full Undo support.

Paths & curves

Implemented OneShot, Loop, PingPong, and weighted Random traversal with straight, Catmull–Rom, and Bézier path shapes.

Production control

Added per-waypoint behavior, interruption and resume, animation syncing, save and restore, crowd controls, and UnityEvent hooks.

03 · The work

Tooling designed around real editing.

Direct manipulation

Waypoints are placed and adjusted in context. The Inspector remains available for precision, while the Scene View handles the spatial work.

Progressive depth

A basic route works with a small setup, while traversal modes, curve controls, waypoint timing, events, and runtime priorities are available when a project needs them.

Unity-native behavior

The tool integrates with NavMeshAgent, Animator, UnityEvents, and Undo so it behaves like part of the editor rather than a disconnected layer.

05 · Shipped result

A reusable tool, not a project-specific script.

Waypoint Path System packages the authoring experience, runtime control, documentation surface, and expected Unity editor behavior into one workflow. It is released as version 1.0.0 on the Unity Asset Store.
