Preface

Time for action – adding the UIHelper class


In order to add the static helper class, perform the following steps:

  1. 1. Add a new class file called UIHelper.cs to the Tank Battles project.

  2. 2. Add the following usi ng directives at the beginning of the UIHelper class file:

    using Microsoft.Xna.Framework;
    using Microsoft.Xna.Framework.Graphics;
    using Microsoft.Xna.Framework.Input;
  3. 3. Modify the declaration of the class to add the modifier static before it. The new class declaration should read:

    static class UIHelper
  4. 4. Add fields to the UIHelper class as follows:

    #region Fields
    public static Texture2D ButtonTexture;
    public static SpriteFont ButtonFont;
    #endregion
  5. 5. Add methods to the UIHelper class as follows:

    #region Helper Methods
    public static UIButton CreateButton(
        string id, 
        string text, 
        int x, 
        int y)
    {
        UIButton b = new UIButton(
            id,
            new Vector2(x,y),
            new Vector2(25 - ButtonFont.MeasureString(text).X / 2, 10),
            ButtonFont,
            text,
       ...
