Csharp 在 Unity Inspector 窗口中获取选定的组件

发布于05月28日

我正在try 制作一个自定义判断器，其功能适用于所有类型的内置组件.

What I'm really trying to do is get as a string the name of the property selected in blue in the inspector when I select it. Is there any way? Example: When highlighting Local Position, is there any way to get "Transform Component - LocalPosition (0,0,0);

我试着阅读API，想知道是否有什么东西可以帮助我，但没有任何运气.还try 使用CustomEditor(TypeOf(Transform))，但在突出显示时无法访问值.

任何帮助都将不胜感激！

推荐答案

FocusInEvent个对你有用吗？

您必须 for each VisualElement或通过根循环添加一个事件，并找到所有VisualElement并将事件添加到其中.然后，您可以获得VisualElement的名称，并在处理事件时使用该名称.

从关于focus events的文档中

public void CreateGUI()
{
    TextField textField = new TextField();
    textField.value = placeHolderText;
    rootVisualElement.Add(textField);

    textField.RegisterCallback<FocusInEvent>(OnFocusInTextField);
    textField.RegisterCallback<FocusOutEvent>(OnFocusOutTextField);
}

private void OnFocusInTextField(FocusInEvent evt)
{
    // If the text field just received focus and the user might want to write
    // or edit the text inside, the placeholder text should be cleared (if active)
    if (placeHolderMode)
    {
        var textField = evt.target as TextField;
        textField.value = "";
    }
}

我已经添加了一个工作示例，正如您所说，它似乎不适用于编辑器.编辑器实现在我的unity版本(2020.3.30f1)中使用以下代码.

using UnityEngine;

public class FocusScript : MonoBehaviour
{

}



using UnityEditor;
using UnityEngine;
using UnityEngine.UIElements;

[CustomEditor(typeof(FocusScript))]
public class CustomEditorFocus : Editor
{
    public override VisualElement CreateInspectorGUI()
    {
        VisualElement myInspector = new VisualElement();

        TextField textField = new TextField();
        textField.name = "test text field";
        textField.value = "test";
        textField.label = "test label";
        myInspector.Add(textField);

        textField.RegisterCallback<FocusInEvent>(OnFocusInTextField);
        return myInspector;
    }

    private void OnFocusInTextField(FocusInEvent evt)
    {
        var textField = evt.target as TextField;
        Debug.Log("Testing with field: " + textField.name);
    }
}
