Rotate gameObject with touch controls OR gameObject follow finger

I am making a simple and my first 2d game like super hexagon… I just made it for windows but I want to make it for android but I don’t know how to control player with touch in android. Do someone have any solution?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class Player : MonoBehaviour {

	public float moveSpeed = 600f;
	float movement = 0f;
	// Update is called once per frame
	void Update () {
		movement = Input.GetAxisRaw("Horizontal");
	}

	private void FixedUpdate() {
		transform.RotateAround(Vector3.zero, Vector3.forward, movement * Time.fixedDeltaTime * -moveSpeed);
	}

	private void OnTriggerEnter2D(Collider2D collision) {
		SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
	}

}

Hey, how are you? Super Hexagon has a kind of “locked” player that only moves by rotating itself, and I honestly don’t like it that way, I prefer it to be freely moved, so the Player script for touch only should be like this:

 `

    using System.Collections;
     using System.Collections.Generic;
     using UnityEngine;
     using UnityEngine.SceneManagement;
     
     public class Player : MonoBehaviour {
     
    	 //determines the player speed
         public float moveSpeed;
    
         // Update is called once per frame
         void Update () 
    	 {
    		 
    		 	//touch screen movement
    				 if(Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved){
    			 Vector2 TouchPosition = Input.GetTouch(0).deltaPosition;
    			 transform.Translate(TouchPosition.x * moveSpeed * Time.deltaTime, TouchPosition.y * moveSpeed * Time.deltaTime, 0);
    		 }
    
    		 }
     
     }

`

Here, moveSpeed is a float that determines the player speed, a value around 5 should be fine (it’s customizable on “Inspector” panel.

Also, you should create a new script for your player, to define screen size limits, I called mine “ScreenLimits”, and used Mathf.Clamp for it, see below:

 

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    
    public class ScreenLimits : MonoBehaviour {
    
    	void Update() {
    
    		//the values of X and Y are customizable as the screen size of your mobile device
    		transform.position = new Vector3(Mathf.Clamp(transform.position.x, -7.7f, 7.7f),
    		Mathf.Clamp(transform.position.y, -14f, 14f), transform.position.z);
    	}
    }

As I put in the script, the value of X and Y are from your mobile screen size, so it can change according to your preferences.

Hope it helps you!
