绘制内置检视面板。
在 OnInspectorGUI 方法中调用此函数可绘制自动检视面板。
如果您不想重新绘制整个检视面板，但又想向其中添加一些按钮，
则可以使用此方法。
另请参阅：OnInspectorGUI。
// This example shows a custom inspector for an
// object "MyPlayer", which has a variable speed.
using UnityEngine;
using UnityEditor;
using System.Collections;
[CustomEditor(typeof(MyPlayer))]
public class Example : Editor {
public override void OnInspectorGUI() {
MyPlayer targetPlayer = (MyPlayer)target;
EditorGUILayout.LabelField ("Some help", "Some other text");
targetPlayer.speed = EditorGUILayout.Slider ("Speed", targetPlayer.speed, 0, 100);
// Show default inspector property editor
DrawDefaultInspector ();
}
}
