\"\"<\/p>\n

Testing one visibility cone idea for enemies. (later will check what other solutions there are..)<\/p>\n

Code:<\/strong><\/p>\n

    \n
  1. If enemy stays inside blue trigger area (attached to player) then\n
      \n
    1. If enemy view angle is towards the player (within view angle range) then\n
        \n
      1. Do Linecast(s) to player bounding circle\/sphere then\n
          \n
        1. if LineCast doesn’t hit obstacles, we can see the player<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

          Now just need to try that in Unity..<\/p>\n

          Version 1.0<\/strong> notes<\/strong>
          \n– Vector3.Dot<\/a> used to check if player is front of the enemy (theres ready code in docs)
          \n–           Physics.LineCast<\/a> for checking if there are any walls between player-enemy
          \n–           Quaternion.LookRotation<\/a> & Quaternion.Slerp<\/a> for rotating & turning towards the player
          \n–           Vector3.MoveTowards<\/a> for moving towards player<\/p>\n
