Crowd Toolkit enabled in the Plugins window

TIP

Crowd Toolkit ships with example maps and example Blueprints (BP_Crowd, BP_CrowdRenderer, BP_RtsController). They live in the plugin's content folder (enable Show Plugin Content in the Content Browser). BasicExample wires up the full selection → order → render loop from Quick Start, NavMeshExample seeds walls from a nav mesh, and FollowExample makes a crowd follow an actor.

Requirements


Engine	Unreal Engine 5.5
Platform	Win64
Module type	Runtime (loaded by default)

Blueprint or C++

Everything in Crowd Toolkit is exposed to Blueprint - you can ship a game with it without writing any C++. The Quick Start shows every step both ways.

To call the API from C++, add the module to your *.Build.cs dependencies:

PublicDependencyModuleNames.AddRange(new[] { "CrowdToolkit" });

Then include the headers you need:

#include "CrowdToolkitActor.h"     // ACrowdToolkitActor - the crowd actor
#include "CrowdToolkitLibrary.h"   // UCrowdToolkitLibrary - GetCrowd + bulk math nodes
