C#/XNA: Simple mouse control with custom pointer

One of the most common tasks of making a game is making a custom pointer for the mouse. This short class allows to add any 2D texture as the mouse pointer.

It also reads mouse position and buttons statuses.

LIBRARY:

DOWNLOAD: XNAMouse.cs

EXAMPLE OF USE:

First of all you will have to make default pointer invisible. Preferably you can put the code in your Game.Initialize() method:

this.IsMouseVisible = false;

Then initialize the XNAMouse object somewhere and use XNAMouse’s Render method inside the Game’s Draw method, XNAMouse’s Update inside Game’s Update method and XNAMouse’s Dispose method inside Game’s UnloadContent method:

public class Game1 : Microsoft.Xna.Framework.Game {
...
   public XNAMouse mouse = new XNAMouse(this.spriteBatch, Texture2D.FromStream(graphics.GraphicsDevice, File.OpenRead("your\\path")), mouse_size);
...
   protected override void Update(GameTime gameTime) {
   ...
      mouse.Update();
   ...      
   }

   protected override void Draw(GameTime gameTime) {
   ...
      mouse.Render();
   ...
   }

   protected override void UnloadContent() {
   ...
      mouse.Dispose();
   ...
   }
}

You give mouse size and texture as arguments in the XNAMouse’s constructor.

I also put button check methods inside this class. I used a little trick to check if mouse buttons were pressed and released:

public bool leftMouseButtonState() {
    if (mouseState.LeftButton == ButtonState.Pressed) LMBpressed = true;
    if (mouseState.LeftButton == ButtonState.Released && LMBpressed) { LMBpressed = false; return true; }
    return false;
}
