Touch: move left and right

Hello everyone,

I'm developing a simple mobile game where you have to move the object left and right by tapping or holding one of the two halves of the screen but i don't know how to do that, I didn't found out any tutorials that explain exactly what I'm looking for. Can you help me please?
Thanks

 

There are tons of examples of this across the internet, so you might want to work on your web searching skills.

You can start with checking out the documentation for Touch input events.

If you want to know if any touches are currently happening, you can check Input.touchCount, which tells you the number of touches happening.
http://docs.unity3d.com/ScriptReference/Input-touchCount.html

You can get info about a specific touch by using Input.GetTouch(0). The zero means the first touch, if you wanted the second touch you would give one as the parameter.
http://docs.unity3d.com/ScriptReference/Input.GetTouch.html
http://docs.unity3d.com/ScriptReference/Touch.html

Then to see what the touch is doing this frame, you can use TouchPhase.
http://docs.unity3d.com/ScriptReference/TouchPhase.html

So here's an example of getting the touch and checking which side of the screen its on.

Code (CSharp):

1. using UnityEngine;
2. public class HalfScreenTouchMovement : MonoBehaviour
3. {
4.     private float screenCenterX;
5.  
6.     private void Start()
7.     {
8.         // save the horizontal center of the screen
9.         screenCenterX = Screen.width * 0.5f;
10.     }
11.  
12.     private void Update()
13.     {
14.         // if there are any touches currently
15.         if(Input.touchCount > 0)
16.         {
17.             // get the first one
18.             Touch firstTouch = Input.GetTouch(0);
19.  
20.             // if it began this frame
21.             if(firstTouch.phase == TouchPhase.Began)
22.             {
23.                 if(firstTouch.position.x > screenCenterX)
24.                 {
25.                     // if the touch position is to the right of center
26.                     // move right
27.                 }
28.                 else if(firstTouch.position.x < screenCenterX)
29.                 {
30.                     // if the touch position is to the left of center
31.                     // move left
32.                 }
33.             }
34.         }
35.     }
36. }
