使用自定义检查器扩展 Unity UI 组件 [英] Extending Unity UI components with custom Inspector

问题描述

是否可以扩展新的 unity ui 组件，例如转换组件?因为当我尝试扩展按钮时没有任何反应，而不是转换组件

Is it possible to extend the new unity ui components like for example the transform component? Because nothing happens when i try to extend the button, instead of the transform component

using UnityEditor;
using UnityEngine;
[CustomEditor(typeof(Transform))]
public class CustomTransform : Editor
{
    public override void OnInspectorGUI()
    {            
    }
}

推荐答案

是的，您可以扩展 UI 组件并为它们编写自己的自定义检查器.您只需要记住使用正确的命名空间并从正确的 Inspector 类继承即可.

Yes you can extend UI components and write them their own custom inspector. You just need to remember to use right namespaces and also inherit from the right Inspector class.

你当然也可以覆盖！

这里的例子是一个 UISegmentedControlButton

Example here is a UISegmentedControlButton

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
using System.Collections;

public class UISegmentedControlButton : Button {

public Sprite offSprite;
public Sprite onSprite;
public Color offTextColor = Color.white;
public Color onTextColor = Color.white;

private bool isSelected;
public bool IsSelected {
    get {
        return isSelected;
    }
    set {
        isSelected = value;

        Text text = this.transform.GetComponentInChildren<Text>();

        if (value) {
            this.GetComponent<Image>().sprite = onSprite;
            text.color = onTextColor;
        } else {
            this.GetComponent<Image>().sprite = offSprite;
            text.color = offTextColor;
        }
    }
}




public override void OnPointerClick(PointerEventData eventData) {

    this.transform.parent.GetComponent<UISegmentedControl>().SelectSegment(this);
    base.OnPointerClick(eventData);
}

}

和它的编辑器类:

附言ButtonEditor 与 UnityEditor.UI.ButtonEditor 不同，因为第一个来自 UnityEngine.ButtonEditor.要从 UnityEditor 访问 .UI，您需要将编辑器脚本放在 Editor 文件夹下

P.S. ButtonEditor is different from UnityEditor.UI.ButtonEditor as the first one is from UnityEngine.ButtonEditor. To access .UI from UnityEditor, you need to put your Editor script under Editor folder

using UnityEngine;
using UnityEditor;
using UnityEngine.UI;
using System.Collections;

[CustomEditor(typeof(UISegmentedControlButton))]
public class UISegmentedControlButtonEditor : UnityEditor.UI.ButtonEditor {


public override void OnInspectorGUI() {

    UISegmentedControlButton component = (UISegmentedControlButton)target;

    base.OnInspectorGUI();

    component.onSprite = (Sprite)EditorGUILayout.ObjectField("On Sprite", component.onSprite, typeof(Sprite), true);
    component.onTextColor = EditorGUILayout.ColorField("On text colour", component.onTextColor);
    component.offSprite = (Sprite)EditorGUILayout.ObjectField("Off Sprite", component.offSprite, typeof(Sprite), true);
    component.offTextColor = EditorGUILayout.ColorField("Off text colour", component.offTextColor);

}
}
