相机相对运动

Question

我运行遇到了一个我无法完全解决的问题。

我正在通过 Unity 制作一个俯视视角的 3D 游戏。我有一个控制器，可以让我的角色在按下移动键时旋转和移动。例如按 "D" 会将播放器对象旋转到面向右，然后 rigidBody 朝那个方向移动，但是如果我旋转相机，播放器将不会相对于相机方向向右移动。

运动：

    //Player Movement
    void HandleMove()
    {
        if (canMove == true)
        {
           //Detect input movement
            var moveHorizontal = Input.GetAxis("Horizontal");
            var moveVertical = Input.GetAxis("Vertical");
            IsMoving = moveHorizontal != 0 || moveVertical != 0;

            Vector3 relative = transform.rotation.eulerAngles;
            relative.y = pCamera.playerRelativeAngle;

            //Rotate the character
            var movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
            var rot = movement * (speed / 10);

            if (attackTimer <= 0 && movement != Vector3.zero)
            {
                Vector3 temp = transform.rotation.eulerAngles;
                var newRotation = Quaternion.LookRotation(rot);
                transform.rotation = Quaternion.RotateTowards(transform.rotation, newRotation, 10F);
            }

            //Move the character
            if (IsMoving && offset.y != 0f)
            {
                movement.y = offset.normalized.y * movement.magnitude;
            }

            var characterMovement = transform.position + movement;
            if (attackTimer <= 0 || !IsGrounded)
            {
                rbody.MovePosition(characterMovement);
            }
    }

我对要做什么有一点想法，但我不能完全掌握它，我有一个相机设置可以 return 它的欧拉角，我正试图找出一种使用它的方法用于相对运动，但我不确定在我的运动控制器中在哪里或如何应用它。

相机：

//Find camera angle
public static float playerRelativeAngle;

//On awake, do this
void Awake()
{
    //Get the cameras angle so we can move the player relative to it???
    playerRelativeAngle = this.transform.localEulerAngles.y;
}

//Update every frame
void Update()
{
    playerRelativeAngle = this.transform.localEulerAngles.y;

    //If the right key is pressed then the caerma rotates to the right 
    if (Input.GetKey("right"))
    {
        this.transform.RotateAround(target.transform.position, Vector3.down, cameraSpeed * Time.deltaTime);
    }
    if (Input.GetKey("left"))
    {
        this.transform.RotateAround(target.transform.position, Vector3.down, -cameraSpeed * Time.deltaTime);
    }
}

非常感谢任何建议。

我设法找到了我的问题的解决方案。

运动：

                //Rotate the character relative to the camera direction
            if (attackTimer <= 0 && moveDirection != Vector3.zero)
            {
                var targetDirection = new Vector3(Input.GetAxis("Horizontal"), 0f, Input.GetAxis("Vertical"));
                targetDirection = Camera.main.transform.TransformDirection(targetDirection);
                targetDirection.y = 0.0f;
                Quaternion targetRotation = Quaternion.LookRotation(targetDirection, Vector3.up);
                float rotationSpeed = 100.0f;
                Quaternion newRotation = Quaternion.Lerp(rbody.rotation, targetRotation, rotationSpeed * Time.deltaTime);

                //Apply the rotation
                rbody.MoveRotation(newRotation);
            }

            //Move the character
            if (IsMoving == true)
            {

                if (Input.GetAxis("Vertical") != 0) //Vertical movement (Up/Down)
                {
                    if (attackTimer <= 0 || !IsGrounded)
                    {
                        rbody.AddForce(transform.forward * speed);
                    }
                }

玩家对象现在相对于相机旋转，然后在按下移动键时向玩家向前方向施加力。

这不是一个完美的解决方案，但希望这对将来的人有所帮助。
