Coding Information

1. About WindMill rotating

Based on the code below in file SpinMe.cs :

float xDegreesPerFrame = Time.deltaTime / 60 * 360 * xRotationsPerMinute;
transform.RotateAround(transform.position, transform.right, xDegreesPerFrame);
float yDegreesPerFrame = Time.deltaTime / 60 * 360 * yRotationsPerMinute;
transform.RotateAround(transform.position, transform.up, yDegreesPerFrame);
float zDegreesPerFrame = Time.deltaTime / 60 * 360 * zRotationsPerMinute;
transform.RotateAround(transform.position, transform.forward, zDegreesPerFrame);

2. About Enemy Path finding

1. Using Nevigation and PathFinding( AI tool ) in Unity to find walkable ground in the environment item.

2. Add nav mesh agent and AI character control functions
3. using the nav mesh agent and AI character control functions in Enemy.cs:

if(distanceToPlayer <= attackRadius)
      {
           aiCharacterControl.SetTarget(player.transform);
       }
       else
       {
           aiCharacterControl.SetTarget(transform);
       }

The enemy will stop when player character run away.

            case walkableLayerNumber:
                // navigate to point on the ground
                walkTarget.transform.position = raycastHit.point;
                aiCharacterControl.SetTarget(walkTarget.transform);
                break;
