如何在 Unity 检查器中根据其他变量值隐藏变量

Question

如何根据统一检查器中的其他变量值隐藏变量。基本上想象一下：如果我有一个名为“CanSprint”的布尔值和一个浮点数“SprintSpeed”，那么我想使它在布尔值为真时显示浮点数，但当布尔值为假时，浮点数隐藏。这只是为了更整洁一点。 谢谢！

您需要查看自定义编辑器脚本 (https://docs.unity3d.com/Manual/editor-CustomEditors.html)，使用自定义编辑器脚本可以随时显示变量。这是使用链接信息的布局：

[CustomEditor(typeof(MyBehaviourClass))]
public class MyEditorClass : Editor
{
    public override void OnInspectorGUI()
    {
        // If we call base the default inspector will get drawn too.
        // Remove this line if you don't want that to happen.
        base.OnInspectorGUI();

        MyBehaviourClass myBehaviour = target as MyBehaviourClass;

        target.myBool = EditorGUILayout.Toggle("myBool", target.myBool);

        if (target.myBool)
        {
            target.someFloat = EditorGUILayout.FloatField ("Some Float:", target.someFloat);

        }
    }
}

请务必将此脚本粘贴在“Editor”文件夹中，将“MyBehaviourClass”更改为您的类类型，将“someFloat”更改为您的浮点数，将“myBool”更改为您的布尔变量。

使用 SetBools 方法和 HideIf(bool name, bool value, object to hide)

using UnityEditor;
using UnityEngine;
using System.Collections.Generic;
using System.Reflection;

public class ExampleClass : MonoBehaviour
{
    public bool exampleBoolA = true;
    public float varToHideA;
    public bool exampleBoolB = false;
    public float varToHideB;
}

[CustomEditor(typeof(ExampleClass)), CanEditMultipleObjects]
public class ExampleEditor : Editor
{
    private List<boolStruct> structList;
    public void OnEnable()
    {
        structList = new List<boolStruct>();
        SetBools();
    }
    private void SetBools()
    {
        HideIf("exampleBoolA", false, "varToHideA");
        HideIf("exampleBoolB", true, "varToHideB");
    }
    private void HideIf(string boolName, bool boolValue, string fieldName)
    {
        boolStruct _boolStruct = new boolStruct()
        {
            targetBoolName = boolName,
            targetBoolValue = boolValue,
            targetVarName = fieldName,
        };
        structList.Add(_boolStruct);
    }
    public override void OnInspectorGUI()
    {
        serializedObject.Update();
        var obj = serializedObject.GetIterator();
        if (obj.NextVisible(true))
        {
            do
            {
                bool visible = true;
                foreach (var i in structList)
                {
                    if (i.targetVarName == obj.name)
                    {
                        FieldInfo boolName = target.GetType().GetField(i.targetBoolName);
                        var boolValue = boolName.GetValue(target);
                        if (boolValue.ToString() != i.targetBoolValue.ToString())
                            visible = false;
                        else
                        {
                            visible = true;
                            break;
                        }
                    }
                }
                if (visible)
                    EditorGUILayout.PropertyField(obj, true);
            } 
            while (obj.NextVisible(false));
        }
        serializedObject.ApplyModifiedProperties();
    }
    private struct boolStruct
    {
        public string targetBoolName {get;set;}
        public bool targetBoolValue {get;set;}
        public string targetVarName {get;set;}
    }
}
