# Fleeing

Add a hazardous obstacle to a crowd simulation and script agents to flee for a set duration.

In this tutorial students will learn how to add a dangerous obstacle to a crowd simulation and program the agents to flee for a specified amount of time.

## Materials

## 1. Fleeing Part 1

[Video](https://connect-mediagw.unity.com/h1/20220906/videos/be1f0ecd-7fa4-4db8-8127-4ec7f87dfb4a_S0904.mp4) ([Transcript (en)](https://connect-mediagw.unity.com/h1/20221012/bfe64f77-a4d6-4a17-9664-39ef464b1422_S0904.vtt))

In this lecture students will setup a project to drop an obstacle into the scene that the agents in the crowd will flee from.

## 2. Fleeing Part 2

[Video](https://connect-mediagw.unity.com/h1/20220906/videos/4fe6eba0-a554-44c5-be45-67de779c81f0_S0905.mp4) ([Transcript (en)](https://connect-mediagw.unity.com/h1/20221012/40b628c5-f916-489a-bca7-6236eb7fa160_S0905.vtt))

In this lecture students will complete the fleeing simulation by adding code to the agents controller to calculate a flee direction.
