Basic AI

This is the recreation of the Basic AI project from the good folks of Renaissance Coders over on Youtube. It was created with Unity 2017.2.0f3.

this is from a previous project, the code is identical to this repository

gif is not identical to the scene in this project

Step By Step

  • import characters from standard assets (menu assets/import package/characters). If you don't see the package you need to re-run the installer.

  • create a plane (menu game object/3d object/plane)

  • scale the plane to 3,0.1,3

  • set the plane to 'navigation static' in the upper right corner of the inspector

  • reveal the navigation menu (menu Window/Navigation)

  • save the scene

  • in the new navigation tab in the inspector, go to bake and then press the bake button

  • go to project/assets/standard assets/characters/ThirdPersonCharacter/Prefabs

  • drop a ThirdPersonController onto the plane

  • set the tag to 'player'

  • position the main camera behind it

  • drag and drop the main camera into ThirdPersonController/EthanSkeleton

you should be able to run around with Ethan now

  • create a sphere

  • rename it to sphere0

  • check isTrigger in the sphere collider

  • duplicate it and move the copy elsewhere

  • rename the copy to sphere1

  • drop an AIThirdPersonController onto the plane

  • remove the 'AI Character Control' component

  • create a folder named 'scripts'

  • create a C# script in it called basicAI

  • drop this text into the script

  • add basicAI component to AI

  • set waypoints to 2

  • add spheres as Element 0 and Element 1

the AI should now walk to sphere0 and 1 and back

  • add component physics/sphere collider

  • check isTrigger

  • set radius to 5 (or whatever)

Once the player approaches the AI, it should start to chase him.
