Touch Controls

Hello,

I was wondering how I could convert this script into using touch controls on Android or IOS.

Would it be as easy as just replacing Input.getMouseButttonDown or Input.mousePosition with GetTouch?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DragObject : MonoBehaviour
6. {
7.     [SerializeField] float moveSpeed;
8.     [SerializeField] float saveDelay = 0.2f;
9.                      float power = 5f;
10.    
11.     Rigidbody2D rb;
12.  
13.     Vector2 dir;
14.     Vector2 lastPosition;
15.  
16.     DestroyObject inAir;
17.    
18.  
19.     bool nextSave = true;
20.     bool canBePushed;
21.     private bool following;
22.    
23.  
24.  
25.     // Use this for initialization
26.     void Start()
27.     {
28.         following = false;
29.         lastPosition = transform.position;
30.         rb = GetComponent<Rigidbody2D>();
31.  
32.         inAir = FindObjectOfType<DestroyObject>();    
33.     }
34.  
35.  
36.  
37.     // Update is called once per frame
38.     void Update()
39.     {
40.         MouseClicksToDrag();
41.     }
42.  
43.  
44.     //drags objects
45.     private void MouseClicksToDrag()
46.         //detects if object has mouse clicked on it
47.     {
48.         if (Input.GetMouseButtonDown(0))
49.         {
50.             RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector3.forward);
51.  
52.             if (hit.collider != null && hit.collider.gameObject == this.gameObject)
53.             {
54.                
55.                 following = true;
56.             }
57.         }
58.  
59.         // detects if object has been released to add forces
60.         if (Input.GetMouseButtonUp(0) && following)
61.         {
62.             following = false;
63.             dir = (Vector2)transform.position - lastPosition;
64.            
65.             canBePushed = true;
66.            
67.         }
68.  
69.         if (following)
70.         {
71.             transform.position = Vector2.Lerp(transform.position, Camera.main.ScreenToWorldPoint(Input.mousePosition), moveSpeed);
72.         }
73.  
74.         if (nextSave)
75.         {
76.             StartCoroutine("SavePosition");
77.         }
78.        
79.     }
80.  
81.     void FixedUpdate()
82.     {
83.             IfCanBePushed();    
84.     }
85.  
86.  
87.     private void IfCanBePushed()
88.     {
89.        
90.         {
91.             if (!inAir.IsFallingTrue())
92.             {
93.                
94.                 if (canBePushed)
95.                 {
96.                    
97.                     canBePushed = false;
98.                     rb.velocity = dir * power;
99.                 }
100.  
101.             }
102.            
103.         }  
104.  
105.  
106.     }
107.  
108.     IEnumerator SavePosition()
109.     {
110.         nextSave = false;
111.         lastPosition = transform.position;
112.         yield return new WaitForSeconds(saveDelay);
113.         nextSave = true;
114.     }
115.  
116.  
117.  
118.  
119.  
120. }
121.  
122.  

 

I don't have any device to test, also you can try to make it working Just as example for touch input

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DragObject : MonoBehaviour
6. {
7.     [SerializeField] float moveSpeed;
8.     [SerializeField] float saveDelay = 0.2f;
9.     float power = 5f;
10.  
11.     Rigidbody2D rb;
12.  
13.     Vector2 dir;
14.     Vector2 lastPosition;
15.  
16.     DestroyObject inAir;
17.  
18.  
19.     bool nextSave = true;
20.     bool canBePushed;
21.     private bool following;
22.  
23.     bool isTouched = false, endTouch = false;
24.     Vector3 touchPosition;
25.     int touchId;
26.  
27.  
28.     // Use this for initialization
29.     void Start()
30.     {
31.         following = false;
32.         lastPosition = transform.position;
33.         rb = GetComponent<Rigidbody2D>();
34.  
35.         inAir = FindObjectOfType<DestroyObject>();
36.     }
37.  
38.  
39.  
40.     // Update is called once per frame
41.     void Update()
42.     {
43.         //here you can try to use Input.GetTouch(0), "for loop" is for multitouch
44.         //maybe you should use id of the touch too, int touchID = touch.fingerId;
45.         //the id can be needed by check if the needed touch was moved
46.         //like if (touch.fingerId == touchId) do something
47.         for (int i = 0; i < Input.touchCount; i++)
48.         {
49.             Touch touch = Input.GetTouch(i);
50.             if (touch.phase == TouchPhase.Began)
51.             {
52.                 isTouched = true;
53.                 touchPosition = touch.position;
54.                 //touchId = touch.fingerId;
55.             }
56.  
57.             if (touch.phase == TouchPhase.Ended)
58.             {
59.                 endTouch = true;
60.             }
61.  
62.             if (touch.phase == TouchPhase.Moved)
63.             {
64.                 //if (touch.fingerId == touchId)
65.                 touchPosition = touch.position;
66.             }
67.         }
68.  
69.         MouseClicksToDrag();
70.     }
71.  
72.  
73.     //drags objects
74.     private void MouseClicksToDrag()
75.     //detects if object has mouse clicked on it
76.     {
77.         //if (Input.GetMouseButtonDown(0))

81.             //RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector3.forward);
82.             RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(touchPosition), Vector3.forward);
83.             if (hit.collider != null && hit.collider.gameObject == this.gameObject)
84.             {
85.  
86.                 following = true;
87.             }
88.         }
89.  
90.         // detects if object has been released to add forces
91.         //if (Input.GetMouseButtonUp(0) && following)
92.         if (endTouch && following)
93.         {
94.             endTouch = false;
95.  
96.             following = false;
97.             dir = (Vector2)transform.position - lastPosition;
98.  
99.             canBePushed = true;
100.  
101.         }
102.  
103.         if (following)
104.         {
105.             //transform.position = Vector2.Lerp(transform.position, Camera.main.ScreenToWorldPoint(Input.mousePosition), moveSpeed);
106.             transform.position = Vector2.Lerp(transform.position, Camera.main.ScreenToWorldPoint(touchPosition), moveSpeed);

112.         }
113.  
114.     }
115.  
116.     void FixedUpdate()
117.     {
118.         IfCanBePushed();
119.     }
120.  
121.  
122.     private void IfCanBePushed()
123.     {
124.  
125.         {
126.             if (!inAir.IsFallingTrue())
127.             {
128.  
129.                 if (canBePushed)
130.                 {
131.  
132.                     canBePushed = false;
133.                     rb.velocity = dir * power;
134.                 }
135.  
136.             }
137.  
138.         }
139.  
140.  
141.     }
142.  
143.     IEnumerator SavePosition()
144.     {
145.         nextSave = false;
146.         lastPosition = transform.position;
147.         yield return new WaitForSeconds(saveDelay);
148.         nextSave = true;
149.     }
150. }
151.  

 

thank you very much, I will try to test this out soon and let you know if this works!
