This page will guide you through the process of implementing NPC pathing and patrols. It's assumed that you know how to do things such as creating a level and using the Root Template Panel. It's recommended you get a feel for the engine by looking through some pages in the Getting Started section.
Different Patrol types
A spline patrol is the simplest form of patrol. It uses a spline to create a pathway that a character will walk along. There's a basic spline patrol creation guide included below.
A patrol set up using triggers. This type of patrol has more control than a spline patrol however it is limited in length to 7 waypoints.
Guide - Basic Spline Patrol
Creating the Static NPC
To get started, place a character on your level using a character root template. For this tutorial, I've made a dog.
Select your character and edit it however you like. We'll come back to it a bit later.
Creating the Patrol Route
In the Root Templates, right-click the Spline section and add a Spline to the level.
Select it and you will have a new tool on the left.
Select the tool, click the spline, and click the point that you want the patrol to begin. Continue adding points to make the patrol route. (You'll be able to make your NPC pause at each of these points if you wish, so keep that in mind when placing them.)
When you're done, select the spline once more and copy the GUID value.
Adding the Patrol Script to Your NPC
The Divinity Engine 2 comes with quite a few premade scripts you can add to your characters and items. Select your NPC and find the scripts option in the sidebar under the Character section. It should look something like this:
Open it and find GEN_SplinePatrol. Assign it to the NPC using the arrows in the middle. Select it and change the SplineGUID to the value we copied earlier. SleepAtNode and SleepOnEveryNode can be used to make the NPC pause along the patrol route.
Click "Ok" and playtest the level. The NPC will follow the route of the spline.
