How can i take only one finger swerve input-CodePudding

My project is a Runner game where character constantly moves forward and if player slides left or right, character moves that position too. But in mobile, if i slide with one finger and touch with my other finger in the mean time, character starts to take 2 inputs and move wrong directions.

This is my code below:

private void Update(){
float newz = transform.position.z   movementSpeed * Time.deltaTime;
float newx = 0, swipeDelta = 0;
      
        if(Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Moved)
        {
            swipeDelta = Input.GetTouch(0).deltaPosition.x / Screen.width;
        }

        newx = transform.position.x   swipeDelta * 5f *Time.deltaTime;

        transform.position = new Vector3(newx, transform.position.y, newz);

}

I have set Input.touchCount to 1 because i want it to get only 1 finger input but it did not work. What should i do to make it work with one finger and make it accurate?

From your code it seems that as soon as you touch with second finger it will just not read location of your first finger.

Input.touchCount == 1 in your if statement looks like a problem for me, it means that if statement will only execute if you have a single finger on your screen. if you change it to Input.touchCount > 0 it will execute even if there are more fingers on the screens and should work correctly since you are already only taking one input with Input.GetTouch(0).

private void Update(){
float newz = transform.position.z   movementSpeed * Time.deltaTime;
float newx = 0, swipeDelta = 0;
  
    if(Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved)
    {
        swipeDelta = Input.GetTouch(0).deltaPosition.x / Screen.width;
    }

    newx = transform.position.x   swipeDelta * 5f *Time.deltaTime;

    transform.position = new Vector3(newx, transform.position.y, newz);

}

Changing Input.touchCount == 1 to Input.touchCount > 0 did not solve my problem. I solved it by adding this line of code in the PlayerController script's Start function:

Input.multiTouchEnabled = false;
