Only one animation playing NON-STOP!!?

Can you post a GIF of the problem?

Watching a character jumping up and down isn't going to tell us anything we don't know already.

If you have the window for your animator open and deselect maximize on play you can see what settings are being triggered. Assu$$anonymous$$g you're using $$anonymous$$ecanim when you say Animator.

@wojtask12 If you mean the functions from the script, then it is the FixedUpdate function -

 private void FixedUpdate()
         {
             m_Grounded = false;
 
             // The player is grounded if a circlecast to the groundcheck position hits anything designated as ground
             // This can be done using layers ins$$anonymous$$d but Sample Assets will not overwrite your project settings.
             Collider2D[] colliders = Physics2D.OverlapCircleAll(m_GroundCheck.position, k_GroundedRadius, m_WhatIsGround);
             for (int i = 0; i < colliders.Length; i++)
             {
                 if (colliders[i].gameObject != gameObject)
                     m_Grounded = true;
             }
             m_Anim.SetBool("Ground", m_Grounded);
         }
 

then the move function-

 public void $$anonymous$$ove(float move, bool jump)
         {
             //only control the player if grounded or airControl is turned on
             if (m_Grounded || m_AirControl)
             {
                 // The Speed animator parameter is set to the absolute value of the horizontal input.
                 m_Anim.SetFloat("Speed", $$anonymous$$athf.Abs(move));
 
                 // $$anonymous$$ove the character
                 m_Rigidbody2D.velocity = new Vector2(move*m_$$anonymous$$axSpeed, m_Rigidbody2D.velocity.y);
 
                 // If the input is moving the player right and the player is facing left...
                 if (move > 0 && !m_FacingRight)
                 {
                     // ... flip the player.
                     Flip();
                 }
                     // Otherwise if the input is moving the player left and the player is facing right...
                 else if (move < 0 && m_FacingRight)
                 {
                     // ... flip the player.
                     Flip();
                 }
             }
             // If the player should jump...
             if (m_Grounded && jump && m_Anim.GetBool("Ground"))
             {
                 // Add a vertical force to the player.
                 m_Grounded = false;
                 m_Anim.SetBool("Ground", false);
                 m_Rigidbody2D.AddForce(new Vector2(0f, m_JumpForce));
             }
         }

@wojtask12 @Cherno Turns out the jumping is a collider problem.

It looks like he is floating on a platform.

Any Ideas?

BTW, he is not jumping.
