Question Help me i joined unity 4 months ago and i dont know how to fix the error CS0138:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine.Debug;
3. using UnityEngine;
4.  
5. public class JoyStickAttack : MonoBehaviour
6. {
7.     private Vector2 startingPoint;
8.     private int leftTouch = 99;
9.  
10.     // Update is called once per frame
11.     void Update()
12.     {
13.         //  Identifying if the button was just pressed or pressed or not pressed
14.         int i = 0;
15.         while (i < Input.TouchCount)
16.             Touch t = Input.GetTouch(i);
17.             Vector2 touchPos = getTouchPosition(t.position) * -1;
18.             if(t.phase == TouchPhase.Began)
19.             {
20.                  if(t.position.x > ScreenWidth / 2)
21.                  {
22.                      shootBullet();
23.                  }
24.                  else
25.                  {
26.                 leftTouch = t.fingerId;
27.                 startingPoint = touchPos;
28.                  }
29.  
30.             }else if(t.phase == TouchPhase.Moved)
31.             {
32.  
33.             }else if(t.phase == TouchPhase.Ended)
34.             {
35.  
36.             }
37.     }
38.  
39.     //Identifyies where is the finger touching
40.     Vector2 getTouchPosition(Vector2 touchPosition)
41.     {
42.         return GetComponent<Camera>().ScreenToWorldPoint(new Vector3(touchPosition.x, touchPostion.y, transform.position.z));
43.     }
44.  
45.  
46.  
47.  
48.     void CharacterMovement(Vector2 direction)
49.     {
50.        
51.     }
52.  
53.     void shootBullet()
54.     {
55.        
56.     }
57. }
58.  

 

Get rid of

using UnityEngine.Debug

.

 

the error is:
error CS0138: A 'using namespace' directive can only be applied to namespaces; 'Debug' is a type not a namespace. Consider a 'using static' directive instead

 

i tried it gave me 5 new errors

 

it gave me the errors
error CS0117: 'Input' does not contain a definition for 'TouchCount'
error CS1023: Embedded statement cannot be a declaration or labeled statement
error CS0103: The name 't' does not exist in the current context
The name 'ScreenWidth' does not exist in the current context
error CS0103: The name 'touchPostion' does not exist in the current context

 

Should be "touchCount", with a lowercase 't'.
https://docs.unity3d.com/ScriptReference/Input-touchCount.html

You're missing curly braces in your while-loop statement.
It looks like you're also creating an endless loop as well, since you're not incrementing the

i

variable that the while-loop's condition is checking.

Why not use a for-loop instead?

Code (CSharp):

1. for(int i = 0; i < Input.touchCount; i++)
2. {
3.    Touch t = Input.GetTouch(i);
4.    //etc...
5. }

You haven't declared a "ScreenWidth" variable anywhere in your script. You're also using a "TouchPhase" variable, but this variable hasn't been declared anywhere either.

You misspelled "touchPosition".

 

oops btw thanks bro
