2d Platformer Jumping Issue plz help.

hi guys I have problem with my jumping code for 2d platformer. it have multipe jumps feature but when i start jumping from fall i have 1 less jump. I think solution can be when jumping from ground -1 jump or when from fall +1 jump but i dont know how to do that. Can someone help me figure it out? Thanks.<3

Code (CSharp):

1.  private void Update()
2.     {
3.         isGrounded = Physics2D.OverlapCircle(groundCheck.position, checkRadius, WhatIsGround);
4.         if(isGrounded == true)
5.         {
6.             extraJumps = 2;
7.         }
8.         if ((Input.GetKeyDown(KeyCode.UpArrow) && extraJumps > 0) || (Input.GetKeyDown(KeyCode.W) && extraJumps > 0))
9.         {
10.             rb.velocity = Vector2.up * jumpForce;
11.             extraJumps--;
12.         }

 

You could add an else if after the grounded check:

Code (csharp):

1.  
2.  private void Update()
3.     {
4.         isGrounded = Physics2D.OverlapCircle(groundCheck.position, checkRadius, WhatIsGround);
5.         if(isGrounded == true)
6.         {
7.             extraJumps = 2;
8.         } else if(extraJumps > 1) // we know we aren't grounded
9.         {
10.             extraJumps = 1;
11.         }
12.         if ((Input.GetKeyDown(KeyCode.UpArrow) && extraJumps > 0) || (Input.GetKeyDown(KeyCode.W) && extraJumps > 0))
13.         {
14.             rb.velocity = Vector2.up * jumpForce;
15.             extraJumps--;
16.         }

 

That only -1 the jump count and ive figured it out myself i needed to - counter when the button is released.

Code (CSharp):

1.  void Update()
2.     {
3.         if(groundCheck.GetComponent<GroundCheck>().GHit)
4.         {
5.             extraJumps = 2;
6.         }
7.  
8.         if((Input.GetKeyDown(KeyCode.W) && extraJumps > 0) || (Input.GetKeyDown(KeyCode.UpArrow) && extraJumps > 0))
9.         {
10.             rb.velocity = Vector2.up * jumpForce;
11.         }
12.  
13.         if(Input.GetKeyUp(KeyCode.W) || Input.GetKeyUp(KeyCode.UpArrow))
14.         {
15.             extraJumps--;
16.         }
17.     }
