Question by MrCrumbl3d · Jan 12, 2018 at 07:42 AM · touchdelaytouchphase

How to apply Time.deltaTime here?

It makes me more touch delay because of this. So help me how to reduce touch delay? If time.deltatime is working then where can i put it?

 if (Application.isMobilePlatform)
         {
             if (Input.touchCount > 0)
             {
                 for (int t = 0; t < Input.touchCount; t++)
                 {
                     Touch touch = Input.GetTouch(t);
                     TouchPhase phase = touch.phase;
 
                     if (phase == TouchPhase.Began)
                     {
                         aimTouchPosition = Camera.main.ScreenToWorldPoint(touch.position);
                         Shoot(aimTouchPosition);
                     }
                 }
             }
         }
     }
 
     public void Shoot(Vector3 aimPosition)
     {
         RaycastHit2D raycastHit2D = Physics2D.Raycast(aimPosition, Vector2.zero);
         if (raycastHit2D.collider != null)
         {
             if (raycastHit2D.collider.tag == "Enemy")
             {
                 raycastHit2D.collider.gameObject.GetComponent<CSGTEnemy>().hit();
             }
            
         }
     }

Looks like you need to set Application.targetFrameRate = 60; .

Hey @MrCrumbl3d i think this line making the delay Camera.main.ScreenToWorldPoint(touch.position);

Because "Camera.main" every time find the camera having MainCamera tag and Finding something in Update function is expensive........... So I tried to optimize your code here it is..............

     Camera cam;
     void Start()
     {
         cam = Camera.main;
     }

     if (Application.isMobilePlatform)
     {
         int total_touches = Input.touchCount;
         if (total_touches > 0)
         {
             Touch[] touches = Input.touches;

             for (int t = 0; t < total_touches; t++)
             {
                 if(touches[t].phase == TouchPhase.Began)
                 {
                     aimTouchPosition = cam.ScreenToWorldPoint(touch.position);
                    Shoot(aimTouchPosition);
                 }
             }
         }
     }




I hope it helps...............
