Как я могу добавить поддержку сенсорного экрана для ОС Android в сценарий моего проигрывателя в Unity С#?

Мне нужно добавить сенсорное управление в мою игру, я не знаю, как это сделать. В моей игре шкала времени очень важна, я прочитал много руководств, и это не работает. Я думаю о чем-то вроде половины экрана слева и половины экрана справа, карта — это дорога, но я думаю, что это не важно. Помоги мне, пожалуйста.

Это игра, как бесконечный бегун. Я очень плохо разбираюсь в сценариях.

public float death =0f;
public float timee;
public float points = 0f;
public float distance = 0f;

{
    timee = Time.timeScale;
}

    {
        GameObject.Find("player").transform.position -= new Vector3((Time.deltaTime * 3.5f )* timee ,0, 0);
    }
    if (Input.GetKey(KeyCode.D) && transform.position.x < 2.5f && transform.position.x > -12.5f)
    {
        GameObject.Find("player").transform.position += new Vector3((Time.deltaTime * 3.5f) * timee , 0, 0);
    } 
    distance = distance + 15 * Time.deltaTime;
