Question by igorjuszczak07 · Apr 12, 2020 at 01:04 PM · unity 2djump

Why does unity not detect any keys except "a" and "d"

I am following this https://www.youtube.com/watch?v=QGDeafTx5ug tutorial and Unity does not detect the "w" key being pressed, it detects "a" and "d" completely fine but it doesn't detect "W" or "space". here is my code:

     public float speed;
     public float jumpforce;
     private float moveinput;
     public Rigidbody2D rb;
     private bool facingright = true;
     private bool isgrounded;
     public Transform groundcheck;
     public float checkradius;
     public LayerMask whatisground;
     private int Jumps;
     public int JumpsValue;
 
     void start()
     {
         rb = GetComponent<Rigidbody2D>();
         Jumps = JumpsValue;
     }
 
     void FixedUpdate()
     {
         moveinput = Input.GetAxis("Horizontal");
         rb.velocity = new Vector2 (moveinput * speed, rb.velocity.y);
 
         if (facingright == false && moveinput > 0)
         {
             flip();
         }
         else if (facingright == true && moveinput < 0)
         {
             flip();
         }
 
         isgrounded = Physics2D.OverlapCircle(groundcheck.position, checkradius, whatisground);
     }
 
     void update()
     {
         if (isgrounded == true)
         {
             Jumps = JumpsValue;
         }
         if  (Input.GetKeyDown(KeyCode.W) && Jumps > 0)
         {
             Debug.Log("WHY AREN'T YOU JUMPING");
             rb.velocity = Vector2.up * jumpforce;
             Jumps--;
         }
     }
     void flip()
     {
         facingright = !facingright;
         Vector3 Scaler = transform.localScale;
         Scaler.x *= -1;
         transform.localScale = Scaler;
     }

sorry about any grammar/spelling mistakes english isn't my first language
