title: Unity Tag and Collider problem while player is jumping
body: <p>This is my player's jump code:</p>
  
  <pre><code>void Update()
  {
      float oldmoveHorizontal = moveHorizontal;
      moveHorizontal = Joystick.Horizontal;
      moveVertical = Joystick.Vertical;    
  
      if (isJumping == false &amp;&amp; moveVertical &gt;= .7f)
      {
          moveVertical = Speed * 70;
          isJumping = true;
      }
  
      ball_move = new Vector2(moveHorizontal, moveVertical);         
      ball_rigid.AddForce(ball_move);
  
      void OnCollisionEnter2D(Collision2D col)
      {
          if (col.gameObject.tag == "Ground")
           {
               isJumping = false;
           }        
      }
  }
  </code></pre>
  
  <p>When ball touches under of the collider it can jump again. How can i block this situation ?
