统一固定四元数旋转

Question

我有这段代码，但我无法找到一个合适的解决方案来将 X 轴夹在 2 个角度值之间。这种情况下怎么办？

public class CameraController : MonoBehaviour {
    public float cameraSmoothness = 5f;

    private Quaternion targetGlobalRotation;
    private Quaternion targetLocalRotation = Quaternion.Identity;

    private void Start(){
        targetGlobalRotation = transform.rotation;
    }

    private void Update(){
        targetGlobalRotation *= Quaternion.Euler(
            Vector3.up * Input.GetAxis("Mouse X"));
        
        targetLocalRotation *= Quaternion.Euler(
            Vector3.right * -Input.GetAxis("Mouse Y"));

        transform.rotation = Quaternion.Lerp(
            transform.rotation,
            targetGlobalRotation * targetLocalRotation,
            cameraSmoothness * Time.deltaTime);
    }
}

为此，您宁愿使用欧拉角，并且仅在应用夹子后将它们转换为Quaternion！

切勿直接触摸Quaternion 的各个组件，除非您真的知道自己在做什么！一个Quaternion 有四个 组件x、y、z 和w，它们都在-1 到1 的范围内移动，所以你尝试的意义不大;)

可能是这样的，例如

// Adjust via Inspector
public float minXRotation = 10;
public float maxXRotation = 90;

// Also adjust via Inspector
public Vector2 sensitivity = Vector2.one;

private float targetYRotation;
private float targetXRotation;

private void Update()
{
    targetYRotation += Input.GetAxis("Mouse X")) * sensitivity.x;      
    targetXRotation -= Input.GetAxis("Mouse Y")) * sensitivity.y;

    targetXRotation = Mathf.Clamp(targetXRotation, minXRotation, maxXRotation);

    var targetRotation = Quaternion.Euler(Vector3.up * targetYRotation) * Quaternion.Euler(Vector3.right * targetXRotation);

    transform.rotation = Quaternion.Lerp(transform.rotation, targetRotation, cameraSmoothness * Time.deltaTime);
}
