unity3d中的玩家控制器無法正確跳躍

我正在制作一個帶有重力切換機制的 3d 游戲。我讓玩家在地圖上走動，它適用于所有角度，但是跳躍是一團糟。我想知道如何才能使跳躍起作用。

跳轉當前只是向本地向上向量添加一個值。我不知道如何解決它。我曾經讓它作業過，但后來我不得不切換到物理運動而不是靜態運動，現在它不起作用。

這是代碼：

void Update()
    {
        //think about moving
        isRunning = (Input.GetKey(KeyCode.LeftControl));
        isShifting = IntToBool((int)((BoolToInt(Input.GetKey(KeyCode.LeftAlt)))*BoolToInt(!isShiftable)) (BoolToInt(Input.GetKey(KeyCode.LeftShift))*BoolToInt(isShiftable)));

        Vector3 forward = transform.forward;//transform.TransformDirection(Vector3.forward);
        Vector3 right = transform.right;//transform.TransformDirection(Vector3.right);

        if (((isShifting && isRunning)||!(isShifting && isRunning))) {
            curSpeedX = walkingSpeed*Input.GetAxis("Vertical");
            curSpeedY = walkingSpeed*Input.GetAxis("Horizontal");
        }
        if (isShifting) {
            curSpeedX = ShiftSpeed*Input.GetAxis("Vertical");
            curSpeedY = ShiftSpeed*Input.GetAxis("Horizontal");
        }
        if (isRunning) {
            curSpeedX = runningSpeed*Input.GetAxis("Vertical");
            curSpeedY = runningSpeed*Input.GetAxis("Horizontal");
        }

        //jump
        if (!isGrounded) {
            ypoa -= gravity;
        }
        if (Input.GetKeyDown(KeyCode.Space)) {
            ypoa = jumpheight;
        }
        
        //actualy move
        moveDir = (ypoa*transform.up) (curSpeedX*transform.forward) (curSpeedY*transform.right);
        rb.velocity = (moveDir*speed);

        moveDir = new Vector3(0,0,0);
    }

    void OnCollisionEnter() {
        jumcount = 0;
        ypoa = 0;
        isGrounded = true;
    }

    void OnCollisionExit() {
        isGrounded = false;
    }

    void OnCollisionStay() {
        isGrounded = true;
    }

我正在使用 unity 2019.4.28f 并且在 Windows 10 上

幫助表示贊賞。

uj5u.com熱心網友回復：

嘗試將您的物理代碼移動到 FixedUpdate 中。如果這不起作用，請您詳細說明一下，例如按空格時會發生什么？

void Update()
    {
        //think about moving
        isRunning = (Input.GetKey(KeyCode.LeftControl));
        isShifting = IntToBool((int)((BoolToInt(Input.GetKey(KeyCode.LeftAlt)))*BoolToInt(!isShiftable)) (BoolToInt(Input.GetKey(KeyCode.LeftShift))*BoolToInt(isShiftable)));

        Vector3 forward = transform.forward;//transform.TransformDirection(Vector3.forward);
        Vector3 right = transform.right;//transform.TransformDirection(Vector3.right);

        if (((isShifting && isRunning)||!(isShifting && isRunning))) {
            curSpeedX = walkingSpeed*Input.GetAxis("Vertical");
            curSpeedY = walkingSpeed*Input.GetAxis("Horizontal");
        }
        if (isShifting) {
            curSpeedX = ShiftSpeed*Input.GetAxis("Vertical");
            curSpeedY = ShiftSpeed*Input.GetAxis("Horizontal");
        }
        if (isRunning) {
            curSpeedX = runningSpeed*Input.GetAxis("Vertical");
            curSpeedY = runningSpeed*Input.GetAxis("Horizontal");
        }

        //jump
        if (!isGrounded) {
            ypoa -= gravity;
        }
        if (Input.GetKeyDown(KeyCode.Space)) {
            ypoa = jumpheight;
        }
        
        //actualy move
        moveDir = (ypoa*transform.up) (curSpeedX*transform.forward) (curSpeedY*transform.right);
        rb.velocity = (moveDir*speed);

        moveDir = new Vector3(0,0,0);
    }

    void OnCollisionEnter() {
        jumcount = 0;
        ypoa = 0;
        isGrounded = true;
    }

    void OnCollisionExit() {
        isGrounded = false;
    }

    void OnCollisionStay() {
        isGrounded = true;
    }
