There's so much more you can do to this simple tree, why don't you give some of these ideas a try?

  • Using a Dot Product node, make it so the AI Character only chases the player when they are in front of the AI. Bonus: Instead of using the AI Character's rotation as part of the Dot Product, use the rotation of the Head Joint. Double Bonus: In the Animation Blueprint add functionality to control the rotation of the head joint, then create a service that has the AI look around.

  • Add attack functionality to the AI Characters and their Behavior Tree.

  • Instead of storing the last known location of the player, store the last 3-5 known locations, then when the player character can no longer be seen, calculate the most likely vector they may have gone, and move along it for a time.

  • They currently just stand their ground when not chasing the character, make it so they move around a bit near their Home Location.

  • Create a patrol point Actor, and make the AI move randomly between them. Bonus: Have the patrol points store a linking patrol point so they will move in a pattern Double Bonus: Have the patrol points store a number of acceptable linking points, then have the AI choose between them. * **Super Bonus**: Use **Environment Query System** to choose the best point for them to patrol.

  • Integrate the Environment Query System into the Behavior tree to choose places to stand or mull around.

  • Change the move speed of the AI Character to a walk when they are patrolling, but make them run when they are chasing the player.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
