how to press gui button at the same time??

i have 2 gui buttons...and i want to press it at the same time...how???

Code (CSharp):

1.  
2.  
3. using UnityEngine;
4. using System.Collections;
5.  
6.  
7.  
8. public class Tap : MonoBehaviour
9. {
10.     public Texture2D buttonImage = null;
11.     public GameObject objectToMove;
12.    
13.     private float timer;
14.    
15.     void Start()
16.     {
17.         timer = 0.0f;
18.     }
19.    
20.     void Update()
21.     {
22.         timer += Time.deltaTime;
23.  
24.     }
25.    
26.     private  void OnGUI()
27.     {
28.         if (timer > 4.0f)
29.         {
30.             if (GUI.Button (new Rect(50,350,300,100),buttonImage))
31.             {
32.                 this.transform.position += new Vector3(-1.0f, 0.0f, 0.0f) ;
33.             }
34.             if (timer > 4.0f) {
35.                 if (GUI.Button (new Rect (400, 350, 300, 100), buttonImage)) {
36.                     this.transform.position += new Vector3 (1, 0, 0);
37.                 }
38.             }
39.         }
40.     }
41. }
42.  

 

Do you mean tap two buttons at the same time on a touch device?

 

I haven't tested the following, but here is the general idea:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Tap : MonoBehaviour
5. {
6.     public Texture2D buttonImage = null;
7.     public GameObject objectToMove;
8.  
9.     private float timer;
10.  
11.     private readonly Rect firstButtonPosition = new Rect(50,350,300,100);
12.     private readonly Rect secondButtonPosition = new Rect(400, 350, 300, 100);
13.  
14.     void Start()
15.     {
16.         timer = 0.0f;
17.     }
18.  
19.     void Update()
20.     {
21.         timer += Time.deltaTime;
22.  
23.         int touchCount = Input.touchCount;
24.         for (int i = 0; i < touchCount; ++i)
25.         {
26.             var touch = Input.GetTouch(i);
27.             if (touch.phase == TouchPhase.Began)
28.             {
29.                 // Get touch point and invert Y-axis.
30.                 var touchPoint = touch.position;
31.                 touchPoint.y = Screen.height - touchPoint.y;
32.  
33.                 if (firstButtonPosition.Contains(touchPoint))
34.                 {
35.                     OnFirstButtonTapped();
36.                 }
37.                 if (secondButtonPosition.Contains(touchPoint))
38.                 {
39.                     OnSecondButtonTapped();
40.                 }
41.             }
42.         }
43.     }
44.  
45.     private void OnGUI()
46.     {
47.         // Here we just draw the buttons without checking for touch input!
48.         if (timer > 4.0f)
49.         {
50.             GUI.Button (firstButtonPosition, buttonImage);
51.             if (timer > 4.0f)
52.             {
53.                 GUI.Button (secondButtonPosition, buttonImage);
54.             }
55.         }
56.     }
57.  
58.     private void OnFirstButtonTapped()
59.     {
60.         // Tapped first button!
61.         this.transform.position += new Vector3(-1.0f, 0.0f, 0.0f) ;
62.     }
63.  
64.     private void OnSecondButtonTapped()
65.     {
66.         // Tapped second button!
67.         this.transform.position += new Vector3 (1, 0, 0);
68.     }
69. }

 

yes

 

Assets/Script/Tap.cs(27,55): error CS0117: `UnityEngine.TouchPhase' does not contain a definition for `Begin'

 

That is a typo which should have read "TouchPhase.Began":

Like I said, this code has not been tested
