Preview窗口除了可以预览模型之外,我们还可以做别的操作。
今天我们来写个小工具在Preview窗口中显示调试信息。
可以看下面的图,同样是打印 health 和 power 的日志,在 Preview 中显示比在 Console 中显示舒服多了。
左边是Console中显示,右边是Preview窗口中显示。
创建Editor目录,然后把下面的脚本放进去

using UnityEngine; using UnityEditor; [CustomEditor( typeof (Object), true )] public class PreviewGUIEditor : Editor { /** Update every 15th frame. */ private const int updateOnFrame = 15; private GUIStyle _previewLabelStyle; private GUIStyle previewLabelStyle { get { if (_previewLabelStyle == null ) { _previewLabelStyle = new GUIStyle( "PreOverlayLabel" ) { richText = false , alignment = TextAnchor.UpperLeft, fontStyle = FontStyle.Normal }; // Try to get a fixed-width font on macOS. var font = Font.CreateDynamicFontFromOSFont( "Monaco" , 12); // Failing that, try to get a fixed-width font on Windows. if (font == null ) font = Font.CreateDynamicFontFromOSFont( "Lucida Console" , 12); // XXX What fixed-width font should I request if we're on Linux? if (font != null ) _previewLabelStyle.font = font; // Debug.Log("Fonts: \n" + string.Join("\n", Font.GetOSInstalledFontNames())); } return _previewLabelStyle; } } public override bool HasPreviewGUI() { return Application.isPlaying; } public override bool RequiresConstantRepaint() { // Only repaint on the nth frame. return Application.isPlaying && Time.frameCount % updateOnFrame == 0; } public override void OnPreviewGUI(Rect rect, GUIStyle background) { string str = target.ToString(); GUI.Label(rect, str, previewLabelStyle); } } |
在我们需要打印日志的类里面 重载ToString()函数,返回需要在preview中输出的内容。
下面是上面截图的示例,一个Player类,在ToString()函数中返回了 health 和 power的输出内容。

using UnityEngine; public class Player : MonoBehaviour { public int health = 10; public int power = 10; // Use this for initialization void Start () { } // Update is called once per frame void Update () { health += 1; power += 2; Debug.LogError( "health = " + health); Debug.LogError( "power = " + power); } public override string ToString() { return "health = " + health+ "\n" + "power = " + power; } } |
