Joystick UI

Hi, i am trying to make a joystick to move my character.
This is my code.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine.UI;
4. using UnityEngine.EventSystems;
5. using UnityEngine;
6.  
7. public class VirtualJoystick : MonoBehaviour , IDragHandler, IPointerDownHandler, IPointerUpHandler
8. {
9.  
10.     private Image BgIMG,JoystickIMG;
11.     private Vector3 InputVector;
12.     private void Start()
13.     {
14.         BgIMG = GetComponent<Image>();
15.         JoystickIMG = transform.GetChild(0).GetComponent<Image>();
16.     }
17.     public virtual void OnDrag(PointerEventData ped)
18.     {
19.         Vector2 pos;
20.         if(RectTransformUtility.ScreenPointToLocalPointInRectangle(BgIMG.rectTransform, ped.position,ped.pressEventCamera,out pos))
21.         {
22.      
23.             pos.x = (pos.x / BgIMG.rectTransform.sizeDelta.x);
24.             pos.y = (pos.y / BgIMG.rectTransform.sizeDelta.y);
25.  
26.             InputVector = new Vector3(pos.x * 2 + 1, 0, pos.y * 2 - 1);
27.             InputVector = (InputVector.magnitude > 1.0f) ? InputVector.normalized: InputVector;
28.  
29.             //Move joystick image
30.             JoystickIMG.rectTransform.anchoredPosition = new Vector3(InputVector.x * (BgIMG.rectTransform.sizeDelta.x / 3), InputVector.z * (BgIMG.rectTransform.sizeDelta.y / 3));
31.             Debug.Log(pos);
32.         }
33.     }
34.     public virtual void OnPointerDown(PointerEventData ped)
35.     {
36.         OnDrag(ped);
37.     }
38.     public virtual void OnPointerUp(PointerEventData ped)
39.     {
40.         InputVector = Vector3.zero;
41.         JoystickIMG.rectTransform.anchoredPosition = Vector3.zero;
42.  
43.     }
44.     public float Horizontal()
45.     {
46.         if (InputVector.x != 0)
47.         {
48.             return InputVector.x;
49.         }
50.         else return Input.GetAxis("Horizontal");
51.     }
52.     public float Vertical()
53.     {
54.         if (InputVector.z != 0)
55.         {
56.             return InputVector.z;
57.         }
58.         else return Input.GetAxis("Vertical");
59.     }
60. }
61.  

And this is my code in my player

Code (CSharp):

1.     private Vector3 MoveInput()
2.     {
3.         Vector3 dir = Vector3.zero;
4.         dir.x = Joystick.Horizontal();
5.         dir.z = Joystick.Vertical();
6.         if (dir.sqrMagnitude > 1)
7.             dir.Normalize();
8.  
9.         return dir;
10.  
11.     }

The joystick is moving and get back to his place when i release the mouse, but the character is not moving.

 

I'd add debugging to determine if dir.x and dir.y are getting non-zero values in MoveInput(). If so then I'd look at how you are using MoveInput()'s return value to move the character.

 

it's zero, what should i change?

 

Anyone?

 

I'd continue adding debugging to figure out where that value is breaking down. Are you properly setting "Joystick" for example? Is OnPointerUp getting called, which resets InputVector to all 0's, before MoveInput is called? Put debugging everywhere and track what is getting called in what order, what values things have, and what might not be behaving as you expect.
