Player want to move left and right from single - touch (Unity) - unity3d

Question

I made the game in Unity Space Shooter. In my Space shooter there is 2 button it work for Left and Right moving. I want when we touch the left button player go to left only in Single Touch same like Right Button also.
This , are the some codes which i used in Game. Please Help me out from this.
TouchControl.cs
using UnityEngine;
using System.Collections;

private Weapon[] weapons;
void Start()
{
playerMove = player.GetComponent<PlayerMovement> ();
}
void CallFire()
{
weapons = player.GetComponentsInChildren<Weapon> ();
foreach (Weapon weapon in weapons) {
if(weapon.enabled == true)
weapon.Fire();
}
}
void Update()
{
// int i = 0;
if(Input.touchCount > 0)
{
for(int i =0; i < Input.touchCount; i++)
{
// if(moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
// {
// if(Input.touchCount > 0)
// {
// playerMove.MoveLeft();
// }
// }
// if(moveRight.HitTest(Input.GetTouch(i).position, Camera.main))
// {
// if(Input.touchCount > 0)
// {
// playerMove.MoveRight();
// }
// }
// if(moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
// {
// if(Input.touchCount > 0)

// Touch t = Input.GetTouch(i);
Touch t = Input.GetTouch (i);
Input.multiTouchEnabled = true;
if(t.phase == TouchPhase.Began || t.phase == TouchPhase.Stationary)
{
if(moveLeft.HitTest(t.position, Camera.main))

Answer 1

In the Player Controller script Create:
public Vector3 playerDirection = Vector3.zero;
Then in touch control instead of:
if (moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
{
if (Input.touchCount > 0)
{
playerMove.MoveLeft();
}
}
if (moveRight.HitTest(Input.GetTouch(i).position, Camera.main))
{
if (Input.touchCount > 0)
{
playerMove.MoveRight();
}
}
Use:
if (moveLeft.HitTest(Input.GetTouch(i).position, Camera.main))
{
if (Input.touchCount > 0)
{
playerMove.playerDirection = Vector3.left;
}
}
if (moveRight.HitTest(Input.GetTouch(i).position, Camera.main))
{
if (Input.touchCount > 0)
{
playerMove.playerDirection = Vector3.right;
}
}
Then in the Update method of Player Controller use:
transform.Translate(playerDirection * speedMove * Time.deltaTime);

Answer 2

public class PlayerController {
public EPlayerState playerState = EPLayerState.Idle;
void Update () {
// If click right button
playerState = EPlayerState.MoveRight;
// Else if click left button
playerState = EPlayerState.MoveLeft
if (playerState == EPlayerState.MoveRight)
// Move player right;
if (playerState == EPlayerState.MoveLeft
// Move player right;
}
}
public enum EPlayerState {
Idle,
MoveRight,
MoveLeft
}
You can also use something like a boolean called isRight, move right when it's true and left when it's false. Then when you click left or right button just change the variable.

Answer 3

`using UnityEngine;
public class HalfScreenTouchMovement : MonoBehaviour
{
private float screenCenterX;
private void Start()
{
// save the horizontal center of the screen
screenCenterX = Screen.width * 0.5f;
}
private void Update()
{
// if there are any touches currently
if(Input.touchCount > 0)
{
// get the first one
Touch firstTouch = Input.GetTouch(0);
// if it began this frame
if(firstTouch.phase == TouchPhase.Began)
{
if(firstTouch.position.x > screenCenterX)
{
// if the touch position is to the right of center
// move right
}
else if(firstTouch.position.x < screenCenterX)
{
// if the touch position is to the left of center
// move left
}
}
}
}
}`

May be helpfull
create script. for example player.cs
public class PlayerController : MonoBehaviour
{
bool swipeRight = false;
bool swipeLeft = false;
bool touchBlock = true;
bool canTouchRight = true;
bool canTouchLeft = true;
void Update()
{
swipeLeft = Input.GetKeyDown("a") || Input.GetKeyDown(KeyCode.LeftArrow);
swipeRight = Input.GetKeyDown("d") || Input.GetKeyDown(KeyCode.RightArrow);
TouchControl();
if(swipeRight) //rightMove logic
else if(swipeLeft) //leftMove logic
}
void TouchControl()
{
if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved && touchBlock == true)
{
touchBlock = false;
// Get movement of the finger since last frame
var touchDeltaPosition = Input.GetTouch(0).deltaPosition;
Debug.Log("touchDeltaPosition "+touchDeltaPosition);
if(touchDeltaPosition.x > 0 && canTouchRight == true)
{
//rightMove
swipeRight = true; canTouchRight = false;
Invoke("DisableSwipeRight",0.2f);
}
else if(touchDeltaPosition.x < 0 && canTouchLeft == true)
{
//leftMove
swipeLeft = true; canTouchLeft = false;
Invoke("DisableSwipeLeft",0.2f);
}
}
}
void DisableSwipeLeft()
{
swipeLeft = false;
touchBlock = true;
canTouchLeft = true;
}
void DisableSwipeRight()
{
swipeRight = false;
touchBlock = true;
canTouchRight = true;
}
}
