How to stop character jumping again if I press space twice in Standard assets (firstpersoncontroller.cs)

Hi everyone

I am fairly new to this, and can’t seem to find the ‘standard assets’ version of the answer.

Currently, my character is bouncing a second time if they land and I pressed the space bar while they were midair. I am trying to alter the firstpersoncontroller.cs to fix this. Could anyone please point me in the right direction?

Ideally, I would only want the character to respond to spacebar if they have already landed on the ground. I thought if (m_CharacterController.isGrounded && !m_Jumping) would fix this.

Here is the main code that seems to contribute below (not mine, from standard unity assets) - scroll down to ‘Where I’ve gone wrong’ to see which part I’ve experimented with…

Note, I’ve also changed it so private bool m_PreviouslyGrounded = true; This prevents the initial landing sound on character start up.

    private Camera m_Camera;
    private bool m_Jump;
    private float m_YRotation;
    private Vector2 m_Input;
    private Vector3 m_MoveDir =;
    private CharacterController m_CharacterController;
    private CollisionFlags m_CollisionFlags;
    private bool m_PreviouslyGrounded = true;
    private Vector3 m_OriginalCameraPosition;
    private float m_StepCycle;
    private float m_NextStep;
    private bool m_Jumping;
    private AudioSource m_AudioSource;

    // Use this for initialization
    private void Start()
        m_CharacterController = GetComponent<CharacterController>();
        m_Camera = Camera.main;
        m_OriginalCameraPosition = m_Camera.transform.localPosition;
        m_HeadBob.Setup(m_Camera, m_StepInterval);
        m_StepCycle = 0f;
        m_NextStep = m_StepCycle/2f;
        m_Jumping = false;
        m_AudioSource = GetComponent<AudioSource>();
		m_MouseLook.Init(transform , m_Camera.transform);

    // Update is called once per frame
    private void Update()
        // the jump state needs to read here to make sure it is not missed
        if (!m_Jump)
            m_Jump = CrossPlatformInputManager.GetButtonDown("Jump");

        if (!m_PreviouslyGrounded && m_CharacterController.isGrounded)
            m_MoveDir.y = 0f;
            m_Jumping = false;
        if (!m_CharacterController.isGrounded && !m_Jumping && m_PreviouslyGrounded)
            m_MoveDir.y = 0f;

        m_PreviouslyGrounded = m_CharacterController.isGrounded;

Where I’ve gone wrong

I’ve tried to say ‘if the player is not jumping’ as a condition, under the assumption that this cannot be true when the character is in the air, but this doesn’t seem to work sadly.

        if (m_CharacterController.isGrounded && !m_Jumping)
            m_MoveDir.y = -m_StickToGroundForce;

            if (m_Jump)
                m_MoveDir.y = m_JumpSpeed;
                m_Jump = false;
                m_Jumping = true;                 

Did you ever figure out an answer to this?
