A.I. Turret Min and Max Rotation Help?

Unity Engine
1

Note: I’m flexible at scripting, so if you code in C# I’ll try to convert it into Javascript.

Ok, so my main problem is having the turret not target the player at a certain angle. There’s a ton of ways to code the same thing. I just need a little help in fixing this puzzle. So, right now I got the turret to target at a radius, and when the player goes in that. The turret simply looks at the player within’ that looking radius. I already know about coding the attack. But just right now, I’ll keep it simple.

Another example, think of it this way. The turret is on a wall. So it of course has a 180 degrees looking before it attacks itself or the building/wall it is on. Now, I have the turret set on its maximum rotation 150 degrees and the minimum rotation 30 degrees. Also the turret is a child object inside its parenting object I would also like to note. When I tried to track it in the inspector. The rotation of the child turret was below -0 and over 0, jumping everywhere. Do I need to try Quaternion or Euler angles?. The code is below.

If you want me to make it more simpler, let me know and I’ll also draw a diagram explaining more about my concept I’m trying to accomplish.
