[SOLVED] Limit Mouse Look View

Hi everyone, I have this SimpleSmoothMouseLook script and i wanna limit it to a specific area like mouse look should only work on half screen not everywhere is it possible and how? Here's the script:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. [AddComponentMenu("Camera/Simple Smooth Mouse Look ")]
5. public class SimpleSmoothMouseLook : MonoBehaviour
6. {
7.     Vector2 _mouseAbsolute;
8.     Vector2 _smoothMouse;
9.    
10.     public Vector2 clampInDegrees = new Vector2(360, 180);
11.     public bool lockCursor;
12.     public Vector2 sensitivity = new Vector2(2, 2);
13.     public Vector2 smoothing = new Vector2(3, 3);
14.     public Vector2 targetDirection;
15.     public Vector2 targetCharacterDirection;
16.    
17.     // Assign this if there's a parent object controlling motion, such as a Character Controller.
18.     // Yaw rotation will affect this object instead of the camera if set.
19.     public GameObject characterBody;
20.    
21.     void Start()
22.     {
23.         // Set target direction to the camera's initial orientation.
24.         targetDirection = transform.localRotation.eulerAngles;
25.        
26.         // Set target direction for the character body to its inital state.
27.         if (characterBody) targetCharacterDirection = characterBody.transform.localRotation.eulerAngles;
28.     }
29.    
30.     void Update()
31.     {
32.         // Ensure the cursor is always locked when set
33.         Screen.lockCursor = lockCursor;
34.        
35.         // Allow the script to clamp based on a desired target value.
36.         var targetOrientation = Quaternion.Euler(targetDirection);
37.         var targetCharacterOrientation = Quaternion.Euler(targetCharacterDirection);
38.        
39.         // Get raw mouse input for a cleaner reading on more sensitive mice.
40.         var mouseDelta = new Vector2(Input.GetAxisRaw("Mouse X"), Input.GetAxisRaw("Mouse Y"));
41.        
42.         // Scale input against the sensitivity setting and multiply that against the smoothing value.
43.         mouseDelta = Vector2.Scale(mouseDelta, new Vector2(sensitivity.x * smoothing.x, sensitivity.y * smoothing.y));
44.        
45.         // Interpolate mouse movement over time to apply smoothing delta.
46.         _smoothMouse.x = Mathf.Lerp(_smoothMouse.x, mouseDelta.x, 1f / smoothing.x);
47.         _smoothMouse.y = Mathf.Lerp(_smoothMouse.y, mouseDelta.y, 1f / smoothing.y);
48.        
49.         // Find the absolute mouse movement value from point zero.
50.         _mouseAbsolute += _smoothMouse;
51.        
52.         // Clamp and apply the local x value first, so as not to be affected by world transforms.
53.         if (clampInDegrees.x < 360)
54.             _mouseAbsolute.x = Mathf.Clamp(_mouseAbsolute.x, -clampInDegrees.x * 0.5f, clampInDegrees.x * 0.5f);
55.        
56.         var xRotation = Quaternion.AngleAxis(-_mouseAbsolute.y, targetOrientation * Vector3.right);
57.         transform.localRotation = xRotation;
58.        
59.         // Then clamp and apply the global y value.
60.         if (clampInDegrees.y < 360)
61.             _mouseAbsolute.y = Mathf.Clamp(_mouseAbsolute.y, -clampInDegrees.y * 0.5f, clampInDegrees.y * 0.5f);
62.        
63.         transform.localRotation *= targetOrientation;
64.        
65.         // If there's a character body that acts as a parent to the camera
66.         if (characterBody)
67.         {
68.             var yRotation = Quaternion.AngleAxis(_mouseAbsolute.x, characterBody.transform.up);
69.             characterBody.transform.localRotation = yRotation;
70.             characterBody.transform.localRotation *= targetCharacterOrientation;
71.         }
72.         else
73.         {
74.             var yRotation = Quaternion.AngleAxis(_mouseAbsolute.x, transform.InverseTransformDirection(Vector3.up));
75.             transform.localRotation *= yRotation;
76.         }
77.     }
78. }

Any Help would be highly Appreciated...

 

You already have a spot where I see you are clamping. So you just need to clamp what value you can lerp to.

 

Thank u so much for the info..i'm kinda noob in C# but i understand little so can you tell me how can i clamp values so that mouse look script should only work on half screen or something? it'll be really helpful!

 

Thanks but your method was to clamp the radius/view i see so my player won't look/rotate up/down or left/right after reaching the decided clamp value but that's not i wanted.....BTW Thanks and I figured it out and customized it how i wanted...i am making a mobile fps game so i needed something to look around and this was working perfectly with touch so instead of limiting mouse view's area i got the code which was in update method and placed it in Repeat OnGUI Button and scaled it to the area i wanted the mouse look to work like half screen so on touching below that area the mouse look doesn't work and my player doesn't go crazy.....anyways i think i puzzled everyone....here's the script Hope it'll help someone else too.
