使用说明

1、把 DebugConsole.cs 放在 Standard Assets 目录下（重要）

2、如果你想修改 DebugConsole的一些参数，把DebugConsole.cs拖给一个GameObject，在属性面板修改属性。

属性解释

    • Debug GUI : Drag the guiText you created here if you wish to override the default.
    • defaultGuiPosition : A vector for the starting position of the first line of output. If you provide your own GUIText then it's position overrides this property.
    • defaultGuiScale : A vector for the scale of the individual lines. Again, this is overridden if you provide your own GUIText.
    • The three colors : are for normal, warning, and error. Set to whatever you like or leave alone.
    • Max messages : How many message lines we will put on the screen at once.
    • Line Spacing : A float for how far down we will move each new line.
    • Draggable : True means you can drag the output around with the mouse at runtime, false means position is locked from mouse input. To drag output at runtime, click once on the uppermost output line to connect it to the mouse, then move to where you want the output displayed and click the mouse again to release it.
    • Visible : The default setting for visibility of the debug output. If set to false (unchecked), you can send data but it wont show until you tell it to, if set to true (checked) it will show all debug output until you tell it not to.
    • PixelCorrect : If set to true and LineSpacing to be on-screen pixels or not, very much like the GUIText property of the same name. Default: false LineSpacing will be in screen coordinates (0.0 - 1.0)

类方法

Log (string message, string color)

  • Adds a message to the list. The color is a string either "normal", "warning" or "error". The color argument is optional and if omitted, the color will default to "normal".

Clear()

  • Clears all of the messages from the list and the screen.

To toggle the visibility use:isVisible (true, false)

  • The property to set the visiblility of the debug output. This property _not_ clear the message list, just hides it. You need to use the Clear() method to clear the list.

To toggle the mouse drag functionality use:isDraggable (true, false)

So for a simple example, to add hello world in warning color (yellow), we type: DebugConsole.Log("hello world", "warning");

To hide the output we type: DebugConsole.isVisible = false;

UseDebugConsole.cs

using UnityEngine;
using System.Collections;

public class UseDebugConsole : MonoBehaviour
{

    // Use this for initialization
    void Start()
    {
        DebugConsole.Log("use debugconsole normal");
        DebugConsole.Log("use debugconsole warning", "warning");
        DebugConsole.Log("use debugconsole error", "error");
    }

    void OnGUI()
    {
        //开始区域
        GUILayout.BeginArea(new Rect(200,10,100,200));
        if (GUILayout.Button("Clean"))
        {
            DebugConsole.Clear();
        }
        if (GUILayout.Button("My Print"))
        {
            DebugConsole.Log("My Print");
        }
        if (GUILayout.Button("isVisible"))
        {
            DebugConsole.isVisible = !DebugConsole.isVisible;
        }
        if (GUILayout.Button("isDraggable"))
        {
            DebugConsole.isDraggable = !DebugConsole.isDraggable;
        }
        GUILayout.EndArea();
    }
}

DebugConsole.cs

/*==== DebugConsole.cs ====================================================
* Class for handling multi-line, multi-color debugging messages.
* Original Author: Jeremy Hollingsworth
* Based On: Version 1.2.1 Mar 02, 2006
* 
* Modified: Simon Waite
* Date: 22 Feb 2007
*
* Modification to original script to allow pixel-correct line spacing
*
* Setting the boolean pixelCorrect changes the units in lineSpacing property
* to pixels, so you have a pixel correct gui font in your console.
*
* It also checks every frame if the screen is resized to make sure the 
* line spacing is correct (To see this; drag and let go in the editor 
* and the text spacing will snap back)
*
* USAGE:
* ::Drop in your standard assets folder (if you want to change any of the
* default settings in the inspector, create an empty GameObject and attach
* this script to it from you standard assets folder.  That will provide
* access to the default settings in the inspector)
* 
* ::To use, call DebugConsole.functionOrProperty() where 
* functionOrProperty = one of the following:
* 
* -Log(string message, string color)  Adds "message" to the list with the
* "color" color. Color is optional and can be any of the following: "error",
* "warning", or "normal".  Default is normal.
* 
* Clear() Clears all messages
* 
* isVisible (true,false)  Toggles the visibility of the output.  Does _not_
* clear the messages.
* 
* isDraggable (true, false)  Toggles mouse drag functionality
* =========================================================================*/
