3D drag move by touch - Space Shooter

Hi Everybody,

I'm looking since 2 days already but I can't find the solution.
I followed the Space Shooter tutorial, but the TouchPad does'nt fit me.

I found other scripts in order to move the GameObject to my finger's position on the screen, but the gameObject is only moving correctly left-right. Unofrtunately, he is also moving to the top of the screen and stops at my top boundary.

I couldn't find another thread about this issue yet, but if you have a link, please let me know.

Here is the code :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5.  
6. public class SimpleTouchPad : MonoBehaviour
7. {
8.  
9.     private Vector3 touchPosition;
10.     public Rigidbody Player;
11.     private Vector3 direction;
12.     public float moveSpeed = 10f;
13.  
14.     private void Update()
15.     {
16.         if(Input.touchCount > 0)
17.         {
18.             Touch touch = Input.GetTouch(0);
19.             touchPosition = Camera.main.ScreenToWorldPoint(touch.position);
20.             touchPosition.z = 0;
21.             direction = touchPosition - transform.position;
22.             Player.velocity = new Vector3(direction.x, 0.0f, direction.y) * moveSpeed;
23.  
24.  
25.             if (touch.phase == TouchPhase.Ended)
26.                 Player.velocity = Vector3.zero;
27.         }
28.     }
29.  
30. }

Your help would be much appreciated.

Nicolas.

 

How are you debugging? Debug.Log is your friend

 

Hi Jeff,

I was replying to my topic, as I just found the solution.

Camera had a rotation of 90° on the X axis.
I had to use y=0 instead of z=0 on the ScreenToWorld touch position, as the camera was a y=10.

Here below the now code :

Code (CSharp):

1. public class SimpleTouchPad : MonoBehaviour
2. {
3.  
4.     private Vector3 touchPosition;
5.     public Rigidbody Player;
6.     private Vector3 direction;
7.     public float moveSpeed;
8.  
9.     private void FixedUpdate()
10.     {
11.         if(Input.touchCount > 0)
12.         {
13.             Touch touch = Input.GetTouch(0);
14.             touchPosition = Camera.main.ScreenToWorldPoint(touch.position);
15.             touchPosition.y = 0;
16.             Vector3 movement = touchPosition - Player.transform.position;
17.             Player.velocity = movement.normalized * moveSpeed;
18.  
19.  
20.             if (touch.phase == TouchPhase.Ended)
21.                 Player.velocity = Vector3.zero;
22.         }
23.     }
24.  
25. }

Hope this will help someone else!
