Flow-Field Crowd Pathfinding Tool

Unity | C#

2024

A drag-and-drop solution for performant, weighted crowd pathfinding.

Flow Field pathfinding is a pathfinding method used to cost-effectively direct high numbers of agents simultaneously - often used in crowd simulations or RTS games.

A flow field method uses only one pathfinding calculation per crowd of agents rather than a calculation per agent, significantly reducing performance overhead.

Quick Setup

Setup is as easy as adding a component into your scene and your character.

---

In-Editor GUI

Quick implementation of traversal costs/weights and blocking out obstacles in terrain.

---

Movement groups

Agents can at any time be assigned to, or removed from movement groups, allowing them to move together or individually.

Other features

• Performant - can direct thousands of agents with little performance impact.

• Uses scriptable objects to store node weight data, which can be dragged and dropped into the Flow Field component - enabling users to easily switch between configurations.

• Demo scenes and example scripts show how and where the tool can be used.
