从检查器调试菜单或Unity编辑器中的检查器中自由编辑四元数 [英] Freely edit quaternion from inspector debug menu or inspector in Unity editor

问题描述

我有一个四元数，我想将其设置为Unity编辑器中对象的transform属性. 检查器"选项卡中的调试模式显示四元数的当前值，并且该值是可编辑的，但是如果不立即将它们覆盖，则无法一一设置字段.看起来Unity在每次编辑后都会尝试对其进行规范化/规范化.如何禁用此功能?还有其他方法可以在统一编辑器中输入四元数的值吗?

I have a quaternion that I would like to set as a transform property on an object in the Unity editor. The debug mode in the inspector tab shows the current value of the quaternion and it is editable, however I can't set fields one by one without them being overwritten immediately. It looks like Unity tries to properize/normalize it after each edit. How can I disable this? Is there any way other way to just type in the value of a quaternion in the unity editor?

将其转换为欧拉角"不是对此问题的可接受答案.

"Convert it to euler angles" is not an acceptable answer to this question.

推荐答案

据我所知，不能禁用该功能.

As far as I know, that functionality can't be disabled.

但是，如果可以使用常规检查器，那么定制检查器可以在这里为您提供帮助.

However, if using the normal inspector is acceptable, a custom inspector can help you here.

首先，一个用于收集局部旋转的类.包含一个布尔值，在您对其进行编辑之前要取消选中该布尔值，以阻止值被更新/覆盖. Vector4在此处用于允许方便的PropertyField出现在自定义编辑器中:

First, a class to collect the local rotation. Includes a boolean to uncheck before you edit it, to stop the values from being updated/overwritten. Vector4 is used here to allow the convenient PropertyField to appear in the custom editor:

using UnityEngine;

public class Demo : MonoBehaviour
{
    public Vector4 rotation;
    public bool updateFromTransform = true;

    void Update()
    {
        // for testing purposes
        // transform.Rotate(0.3f * Vector3.up); 

        if (updateFromTransform)
        {
            rotation.x = transform.localRotation.x;
            rotation.y = transform.localRotation.y;
            rotation.z = transform.localRotation.z;
            rotation.w = transform.localRotation.w;
        }

    }
}

还有一个自定义编辑器，其中包括一个按钮，用于将对Vector4的更改应用于本地旋转:

And a custom editor including a button to apply changes to the Vector4 to the local rotation:

using UnityEngine;
using UnityEditor;

[CustomEditor(typeof(Demo))]
public class DemoEditor : Editor

    SerializedProperty rotation
    SerializedProperty updateFromTransform;
    private void OnEnable()
    {
        rotation = serializedObject.FindProperty("rotation");
        updateFromTransform = serializedObject.FindProperty("updateFromTransform");
    }

    public override void OnInspectorGUI()
    {
        Demo d = (Demo)target;
        serializedObject.Update();

        EditorGUILayout.PropertyField(updateFromTransform);
        EditorGUILayout.PropertyField(rotation);

        serializedObject.ApplyModifiedProperties();

        if (GUILayout.Button("Apply as local rotation"))
        {
            d.updateFromTransform = true;
            d.transform.localRotation = 
                    new Quaternion(d.rotation.x, d.rotation.y, d.rotation.z, d.rotation.w);
        }

    }
}
