Use Pinup and PinupManager to Create pinups in XNA, WPXNA (17)

Introduction/Catalog

I have developed some games on Windows Phone. Here, I'll share my experiences and gradually upload some classes, no good name, I just call it WPXNA. (Some example code may not be stringent enough.)

• Pinup
• PinupManager
• Example

Pinup

In the game, pinup can be used to display content such as text or a picture. For example: display "good", "amazing", it can also be used to show HP.

We define the Pinup class to represent the pinup, it is a very simple class.

internal abstract class Pinup
 : Spirit
{

 protected Pinup ( IPlayScene scene, int type, Vector2 location, 
    string movieName, float speed, int angle, int width, 
    int height, double destroySecond )
  : base ( scene, type, location, movieName,
  null,
  speed,
  angle,
  null,
  width, height, destroySecond,
  true,
  false,
  false,
  0
  )
 { }

 protected override Vector2 getMovieLocation ( )
 { return this.Location - this.halfSize; }

 protected override void updateSpeed ( )
 {
  this.xSpeed = Calculator.Cos ( this.angle ) * this.speed;
  this.ySpeed = Calculator.Sin ( this.angle ) * this.speed;

  base.updateSpeed ( );
 }

 protected override void move ( )
 {
  this.Location.X += this.xSpeed;
  this.Location.Y += this.ySpeed;
 }

}

As members of this class have no special, so you can reference the Spirit class.

PinupManager

PinupManager class is derived from class SpiritManager<T>, the default order is 4000.

internal class PinupManager
 : SpiritManager<Pinup>
{

 internal PinupManager ( )
  : base ( 4000 )
 { }

}

Example

SceneT18 is an extension of SceneT17, in addition to the functions of SceneT17, it will also display a pinup.

We have defined a class MyHit which represents a pinup, we will show MyHit after the first shot.

internal class MyHit
 : Pinup
{

 internal MyHit ( IPlayScene scene, Vector2 location )
  : base ( scene, 1, location, "mypinup", 0, 0,
  30, 30,
  1
  )
 { }

}

Then, we define some fields.

private PinupManager pinupManager;

private bool is1Hit = false;

Field is1Hit is used to indicate whether the bird is hit for the first time.

internal SceneT18 ( )
 : base ( Vector2.Zero, GestureType.None, "background1",
 new Resource[] {
  new Resource ( "bird2.image", ResourceType.Image, @"image\bird2" ),
  new Resource ( "bullet.image", ResourceType.Image, @"image\bullet" ),
  new Resource ( "item.image", ResourceType.Image, @"image\item" ),
  new Resource ( "pinup.image", ResourceType.Image, @"image\pinup1" ),
  new Resource ( "go.image", ResourceType.Image, @"image\button1" ),
 },
 new Making[] {
  new Movie ( "bird", "bird2.image", 80, 80, 5, "live",
   new MovieSequence ( "live", true, new Point ( 1, 1 ), new Point ( 2, 1 ) )
   ),
  new Movie ( "mybutton", "bullet.image", 10, 10, 0, "b",
   new MovieSequence ( "b", new Point ( 1, 1 ) )
   ),
  new Movie ( "myitem", "item.image", 30, 30, 0, "i",
   new MovieSequence ( "i", new Point ( 1, 1 ) )
   ),
  new Movie ( "mypinup", "pinup.image", 100, 50, 0, "p",
   new MovieSequence ( "p", new Point ( 1, 1 ) )
   ),
  new Button ( "b.go", "go.image", "GO", 
  new Vector2 ( 10, 690 ), 100, 50, new Point ( 1, 1 ) ),
 }
 )
{
 // ...

 this.pinupManager = new PinupManager ( );
 this.pinupManager.Scene = this;

 // ...
}

In the SceneT18 constructor, we'll create a new PinupManager.

private void bulletHitTesting ( object sender, BulletHitAreaEventArgs e )
{

 if ( !this.bird.IsDied && e.HitArea.HitTest ( this.bird.HitArea ) )
 {
  e.IsHit = true;
  e.Targets = new IAssailable[] { this.bird };

  if ( !this.is1Hit )
  {
   this.is1Hit = true;
   this.pinupManager.Append ( new MyHit ( this, new Vector2 ( 0, 400 ) ) );
  }

 }

}

We use field is1Hit to decide whether to display the pinup, and display time is 1 second.
