unity 3d 中的播放器控制器无法正确跳跃

Question

我正在制作一款带有重力切换机制的 3d 游戏。我让玩家在地图上四处走动，它适用于所有角度，但是跳跃一团糟。我想知道我怎样才能让跳跃成功。

目前的跳跃只是给局部向上向量加了一个值。我不知道如何解决它。我让它在某一时刻工作，但后来我不得不切换到物理运动而不是静态运动，现在它不起作用了。

代码如下：


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 并在 windows 10

感谢帮助。

尝试将您的物理代码移至 FixedUpdate。如果这不起作用，请您详细说明一下，例如按 space 会发生什么？

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;
    }
