Enemy AIs will flee and seek cover from the Player or any NPC. They will crouch or stand behind cover depending on the cover setting.
No coding is required for implementation. Everything is drag and drop, the settings are set in the Inspector.
IMPORTANT
This system uses the NavMesh, the Ethan model, and the ThirdPersonCharacter Script from the Standard Assets to move and animate the AIs. You will be required to import the Characters and Cameras Standard Assets separately.
