PropertyScope

Description

创建一个属性封装器，可用于使常规 GUI 控件与 SerializedProperty 配合使用。

大多数 EditorGUI 和 EditorGUILayout GUI 控件已具有与 SerializedProperty 配合使用的重载。 但是，对于不处理 SerializedProperty 的 GUI 控件，您可以按以下所示示例将它们封装到 BeginProperty 和 EndProperty 中。 您也可以将其用于自己的自定义 GUI 控件。

BeginProperty and EndProperty automatically handle default labels, bold font for Prefab overrides, revert to Prefab right click menu, and setting showMixedValue to true if the values of the property are different when multi-object editing.

using UnityEngine;
using UnityEditor;

public class ExampleClass : MonoBehaviour
{
    // A slider function that takes a SerializedProperty
    void Slider(Rect position, SerializedProperty prop, float leftValue, float rightValue, GUIContent label)
    {
        using (var scope = new EditorGUI.PropertyScope(position, label, prop))
        {
            label = scope.content;
            EditorGUI.BeginChangeCheck();
            var newValue = EditorGUI.Slider(position, label, prop.floatValue, leftValue, rightValue);
            // Only assign the value back if it was actually changed by the user.
            // Otherwise a single value will be assigned to all objects when multi-object editing,
            // even when the user didn't touch the control.
            if (EditorGUI.EndChangeCheck())
                prop.floatValue = newValue;
        }
    }
}
