Code examples

I am looking at the UltimaSDK for a couple ideas and having never seriously examined it before I was particularly interested in seeing some code examples. The following are the posts I found in this forum which offer code snippets for which no one protested. I make no claims for accuracy or suitability or versioning, I only gathered these posts together. (Primarily for my own benefit.)

If any veteran users have working code examples for simple or not-so-simple tasks to offer new users, please post them here.

I have been working on a program dealing with the new Ultima.dll here and wanted to post a few code snippets.


Playing the sound:

    public static void PlaySound(MemoryStream ms)
    {
        System.Media.SoundPlayer sp = new System.Media.SoundPlayer();
        sp.Stream = ms;
        sp.Play();
    }

Get sound file name with the sound id:

    public static string GetSoundName(int soundID)
    {
        if (soundID < 0) { return null; }

        m_Index.BaseStream.Seek((long)(soundID * 12), SeekOrigin.Begin);

        int offset = m_Index.ReadInt32();
        int length = m_Index.ReadInt32();
        int extra = m_Index.ReadInt32();
        if ((offset < 0) || (length <= 0))
        {
            if (!m_Translations.TryGetValue(soundID, out soundID)) { return null; }
            m_Index.BaseStream.Seek((long)(soundID * 12), SeekOrigin.Begin);
            offset = m_Index.ReadInt32();
            length = m_Index.ReadInt32();
            extra = m_Index.ReadInt32();
        }
        if ((offset < 0) || (length <= 0)) { return null; }
        byte[] buffer = newbyte[40];
        m_Stream.Seek((long)(offset), SeekOrigin.Begin);
        m_Stream.Read(buffer, 0, 40);
        return System.Text.Encoding.UTF8.GetString(buffer);
    }

Sorry, that was basicly a rip off from GetSound lol. I needed a quick fix and that should do it.

That would be very nice.

Here's an example of how to use the new StringList methods:

using System;
using Server;
using Ultima;

namespace Joeku.Test
{
	public class Test_Main
	{
		public static StringList StringList = new StringList( "ENU" ); // Initialize an instance of the StringList.

		public static void Initialize()
		{
			// If you want to simply convert a cliloc into a string...
			Console.WriteLine( StringList.Table[1076267] ); // Boiling Cauldron
				// Boiling Cauldron

			// If you want to format a cliloc with args...
			Console.WriteLine( StringList.Format( 1070749, "John", "Amy" ) ); // ~1_val~ has joined ~2_val~.
				// John has joined Amy.

			// If you want to format a cliloc with a single arg string that is separated by tabs...
			string args = "Jim\tKelly"; // "\t" is the Tab character
			Console.WriteLine( StringList.SplitFormat( 1070749, args ) ); // ~1_val~ has joined ~2_val~.
				// Jim has joined Kelly.
		}
	}
}

Fully compiled and functional with RunUO 2.0 RC2.

Here is little example how to obtain string from cliloc with Ultima SDK.

using Ultima;

private static readonly StringList list =  new StringList();
public string GetString(int number)
{
    return list.Table[number] as string;
}

If the Cliloc entry doesn't exist method will return null. I hope it is what you want.

You should know that a hue isn't just a color. It's a list of colors (otherwise, hueing an item would like pretty bad).

You can get a System.Drawing.Colors from a Hue - for example the first one from the list - by...

Hue hue = Ultima.Hues.List[<HueID>];
Color color = hue.getColor(0);

Sorry for my stupidity, but I don't actually get how that Client.FindLocation() works...?
What variabes should I give for it, or does it just return something...?

Yeah, just begining with this kind of stuff...


Edit:
Okey... After little googleing...
Got how ref variables works, and here's finally my code for character position:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Ultima;


namespace UORadar
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            Ultima.Client.Calibrate();

            int CharX;
            int CharY;
            int CharZ;
            int CharF;
            CharX = 0;
            CharY = 0;
            CharZ = 0;
            CharF = 0;
            Ultima.Client.FindLocation(ref CharX, ref CharY, ref CharZ, ref CharF);
            Bitmap radarmap = Ultima.Map.Felucca.GetImage(CharX / 8, CharY / 8, 100, 100);
            pictureBox1.Image = radarmap;
            xpos.Text = Convert.ToString(CharX);
            ypos.Text = Convert.ToString(CharY);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string viesti = ": " + msg.Text;
            Client.SendText(viesti);
        }
    }
}

Something like that

I know this post is pretty old but just wanted to say thanks as its helpful as an intro into what the UO sdk code actually looks like before delving in.
