         }
 
         private void Update()
         {
             Time.timeScale = 0.075f;
         }
 
         public void OnJumpPressed()
         {
             control.Jump = true;
         }
 
         public void OnJumpReleased()
         {
             if (!control.Start)
             {
                 control.Start = true;
             }
 
             control.Jump = false;
         }

         {
             control.Dash = true;
         }

             }
             control.Dash = false;
         }
 
         public void OnSlidePressed()
         {
             control.isOnSlope = true;
         }
 
         public void OnSlideReleased()
         {
             if (!control.Start)
             {
                 control.Start = true;
             }
             control.isOnSlope = false;
         }
     }
 }

MY SCRIPT for double jump

         {
             if (!control.Start)
             {
                 control.Start = true;
             }
             control.isOnSlope = false;
         }
     }
 }

Problem is double jump is detecting even if i press it single time. can' figure out how to make, Event trigger to detect Double Tap

Things to know

• I am using Finite state machine for player Control (combination with scriptable objects).

• thing are working fine when i use mouse click for jump.

• i am using Event Trigger. PointerDown & PointerUp to be extact.

• My project is on github i'll share if anyone willing to Help.
