Question by niter412 · Dec 30, 2009 at 04:18 AM · iphone

Message Displayer

Hi,

I have question about this:

http://www.unifycommunity.com/wiki/index.php?title=MessageDisplayer

using UnityEngine; using System.Collections;

// Use this script on a guiText object to have status messages // Just call messageDisplayerObject.DisplayMessage("hello") and you'll // get a line of self disappearing messages.

public class MessageDisplayer : MonoBehaviour { ArrayList messages = new ArrayList();

 public void DisplayMessage(string message)
 {
     messages.Add(message);
     UpdateDisplay();
     Invoke("DeleteOldestMessage", 5F);
 }

 void DeleteOldestMessage()
 {
     // The following "if statement" protects this function from
     // getting called by SendMessage from another script and
     // crashing.
     if (messages.Count > 0)
     {
         messages.RemoveAt(0);
         UpdateDisplay();
     }
 }

 void UpdateDisplay()
 {
     string formattedMessages = "";

     foreach (string message in messages)
     {
         formattedMessages += message + "\n";
     }

     guiText.text = formattedMessages;
 }

}

If I would like to use messageDisplayerObject.DisplayMessage("hello"), do I have to create an object of MessageDisplayer? If so how can I do that?

Thank you very much.

Or how can I make this static so I do not have to create an object every time when I want to use the Dispaly$$anonymous$$essage function? I added the static before the void but it is saying that UpdateDispaly() also needs to be static so I changed that to static as well and now it's saying: An object reference is required for the nonstatic field, method or property.

Thank you!

You need to attach this script to a GUIText object. Then, you can make a call to nameOfYourGUITextObject.DisplayMessage in any script which has a reference to your GUIText object in order to display a message.

What you mean by reference to my GUIText object?

A variable declared in some script which has your GUITextObject as a value.
