To apply on screen several Joysticks and buttons, first i created one base class called MultiTouch:

This MultiTouch class, detects touchs on screen 1 time per frame.

After, I created two derived class of this, one for Joysticks (MultiTouchJoystick) and one for the buttons (MultiTouchButton), including a system of events that invokes a specific method:

MultiTouchJoystick envent methods: JoystickNone, JoystickEnter, JoystickStay, JoystickExit.
MultiTouchButton event methods: TouchNone, TouchEnter, TouchStay, TouchExit.

Event System incorporates 4 states types: None, Enter, Stay, and Exit.

HOW TO USE

To use these two types of controls (Joystick and Button) must create derived class of MultiTouchJoystick or MultiTouchButton.

For example, if you want two buttons A and B, you create two derived class called ButtonA and ButtonB of MultiTouchButton.

Then you can use the event system (None, Enter, Stay, Exit) adding methods: TouchNone, TouchEnter, TouchStay and TouchExit.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class ButtonA : MultiTouchButton {
5.  
6.     bool show = false;
7.  
8.  
9.     void TouchEnter(){
10.  
11.         Debug.Log("EnterButtonA");
12.     }
13.  
14.     void TouchStay(){
15.  
16.         show = true;
17.  
18.     }
19.  
20.     void TouchExit(){
21.  
22.         show = false;
23.         Debug.Log("ExitButtonA");
24.  
25.     }
26.  
27.     void OnGUI(){
28.  
29.         if(show) GUILayout.Label("FireButtonA");
30.  
31.     }
32.  
33. }

Similarly, if you want to create two Joystick, you create two derived class called Joystick1 and Joystick2 of MultiTouchJoystick.

Then you can use the event system, adding methods: JoystickNone, JoystickEnter, JoystickStay, JoystickExit.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class JoystickA : MultiTouchJoystick {
5.  
6.     public Rect rect;
7.  
8.     void JoystickEnter(){
9.    
10.         Debug.Log("EnterJoystickA");
11.     }
12.  
13.  
14.     void JoystickExit(){
15.    
16.         Debug.Log("ExitJoystickA");
17.    
18.     }
19.  
20.     void OnGUI(){
21.    
22.         GUI.Label(this.rect, "JoystickA,  X: "+this.Horizontal+"   Y: "+this.Vertical);
23.    
24.     }
25.  
26. }
