Question

我可以使用更大的鼠标输入在轴上旋转立方体，但是不知道如何阻止短轴的输入直到鼠标移开。

脚本包含最近90度角的捕捉。不是那么优雅，但我会把它留给另一个帖子。

这是我的代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class s_rotate_test : MonoBehaviour {
    float mouseX;
    float mouseY;

    public float rotationSpeed = 100f;
    public float smoothing = 2f;

    // Use this for initialization
    void Start ()  {
        Debug.Log (transform.rotation.x + " | " + transform.rotation.y + " | " + transform.rotation.z);
    }

    // Update is called once per frame
    void Update () {
        if(Input.GetMouseButton(0)) {
            mouseX = Input.GetAxis("Mouse X");
            mouseY = Input.GetAxis("Mouse Y");

            float rotationY = -mouseX * rotationSpeed * Time.deltaTime;
            float rotationX = mouseY * rotationSpeed * Time.deltaTime;

            if (mouseX * mouseX > mouseY * mouseY) {
                transform.Rotate (0, rotationY, 0 /*, Space.World*/);
            } else if (mouseY * mouseY > mouseX * mouseX) {
                transform.Rotate (rotationX, 0, 0/*, Space.World*/);
            }
        }
        if (Input.GetMouseButtonUp (0)) {
            // Y AXIS SNAPS -------------------------------------------------------------------------------------------
            if (transform.rotation.eulerAngles.y > 0 && transform.rotation.eulerAngles.y <= 45) {
                Quaternion targetRotation = Quaternion.Euler (0, 0, 0);
                transform.rotation = Quaternion.Lerp (transform.rotation, targetRotation, smoothing);
            }
        }
    }
    //------------------------------------------------------------------------
}

您需要一些东西来跟踪当前的拖动状态。

public enum State{
  Normal,
  DraggingX,
  DraggingY
}
// This is a field
State draggingState = State.Normal;

使用此设置，仅在状态为Normal时才检查最大输入。确定正确的轴后，将状态设置为DraggingX（或Y）。按下鼠标时，执行以下操作：

switch(dragginState){
  case State.Normal:
    // Get Greatest input (suppose it's X)
    draggingState = State.DraggingX;
    break;
  case State.DraggingX:
    // Use only X input
    break;
  case State.DraggingY:
    // Use only Y input
    break;
}

发布后，您再次设置draggingState = State.Normal;。
