GUI show only while mouse is held down

This script controls the cameras FOV when "Fire2" is pressed as well as displaying a GUI texture. However, once the user presses the button once, the texture displays and does not disappear until the button is pressed again - I want it to only show when the button is held down?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class awpScopeIn : MonoBehaviour {
5.  
6.     public Texture scopeGUI;
7.     private bool _isScoped = false;
8.     public Color color = Color.black;
9.     private Camera cam;
10.     public GameObject awp_graphics;
11.  
12.     void Start()
13.     {
14.         cam = GetComponentInParent( typeof(Camera) ) as Camera;
15.         cam.clearFlags = CameraClearFlags.SolidColor;
16.         cam.fieldOfView = 70f;
17.     }
18.    
19.     void OnGUI()
20.     {
21.         float width = 600;
22.         float height = 600;
23.        
24.         if (_isScoped) {
25.             GUI.DrawTexture (new Rect ((Screen.width / 2) - (width/2), (Screen.height / 2) - (height/2), width, height), scopeGUI);  
26.         }
27.     }
28.    
29.     void Update()
30.     {
31.         if(Input.GetButtonDown("Fire2"))
32.         {
33.             _isScoped = !_isScoped;
34.             cam.backgroundColor = color;
35.             cam.fieldOfView = 45f;
36.             awp_graphics.gameObject.SetActive(false);
37.         }else if(Input.GetButtonUp("Fire2"))
38.         {
39.             cam.fieldOfView = 70f;
40.             awp_graphics.gameObject.SetActive(true);
41.         }
42.    
43.     }
44. }
45.  

 

You forgot to set isScoped to false once getButtonUp is called. Right now, you have isScoped being toggled on button down, so it toggles once the button is pressed again.

 

Oh right yeah, my bad thanks
