统一播放器 controller 3d 没有正确跳跃

Question

i am making a 3d game with a gravity switching mechanic. i have the player walking around the map, and it works on all angles, however the jump is a mess. i was wondering how i could make the jump work.

the jump currently just adds a value to the local up vector. i have no idea how to fix it. i had it working at one point but then i had to switch to physical movement instead of static movement and now it doesn't work.

here is the code:

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;
    }

i am using unity 2019.4.28f and am on windows 10

help is appreciated.

Try to move your Physics code into FixedUpdate. If this doesn't work, could you please elaborate more eg What happens when you press space?

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;
    }
