Hello All,[/font]

I am having trouble keeping track of which sprite i want to control in game for eaxmple getting into a car sprite that is in a list of sprites and controlling it. i tried using a for statement but it didnt work the way i like ive been told to look into a foreach statement for this.


///////////////////////////// CollisionDetection.cs //////////////////////////////////////
public void Players_selected_Car(GameTime gameTime, Players player, Cars pCars, CarManager carManager)
{
foreach (Cars Cars in pCars)
{
currentState = Keyboard.GetState();
if (player.myPlayer.BoundingBoxRec.Intersects(pCars.myCar.BoundingBoxRec)
&& currentState.IsKeyDown(Keys.E) && !previousState.IsKeyDown(Keys.E))
{
player.PlayersDriving = !player.PlayersDriving;
}
previousState = currentState;
}
}
//////////////////////////////////////////////////////////////////////////////////////////////////////////

///////////////////////////////////// CarManager.cs /////////////////////////////
public void LoadContent(ContentManager Content)
{
pcarTexture = Content.Load<Texture2D>("Cars Spritesheet");
this.initialFrame = new Rectangle(0, 0, 54, 70);
this.frameCount = 0;
pcarTexture.Bounds.Equals(new Rectangle(0, 0, 39, 50));
}
public void Initialize()
{
parked_Cars = new List<Cars>();

setup_ParkedCars();
}
public void SpawnCars(int space)
{
Cars doublestriped_GreenCar = new Cars(pcarTexture,
new Vector2(700, 270),
new Rectangle(0, 0, 54, 70),
0);
Cars doublestriped_BlueCar = new Cars(pcarTexture,
new Vector2(700, 320),
new Rectangle(0, 78, 54, 70),
0);
Cars Black_SUV = new Cars(pcarTexture,
new Vector2(700, 390),
new Rectangle(29, 196, 35, 63),
0);
Cars Tan_SUV = new Cars(pcarTexture,
new Vector2(700, 460),
new Rectangle(29, 299, 35, 63),
0);
}
public void Draw(SpriteBatch spriteBatch)
{
foreach (Cars Cars in parked_Cars)
{
Cars.Draw(spriteBatch);
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////////////

/////////////////////////////////////////// Cars.cs /////////////////////////////////
public IEnumerator<Cars> GetEnumerator(); // Dont know how to use this properly
public Cars(Texture2D texture,
Vector2 location,
Rectangle initialFrame,
int frameCount)
{
myCar = new AnimatedSprites(location,
texture,
initialFrame,
Vector2.Zero);
previousLocation = location;
currentWaypoint = location;
}


There is much more in those classes but i felt there was no need to post it for what i need help in.

i dont know how to use GetEnumerator for my list of sprites

Thanks to all those who help.

Hi.

I think that you are making a mistake :s. You should not have a class cars, but rather have a class class "car" and then have a List<Car> containing all the game cars.
Also you are using the foreach currently here:

foreach (Cars Cars in parked_Cars)
{
Cars.Draw(spriteBatch);
}


Probably i am reading it wrong. That said, Enumerators only make sense in collections nad by looking at the Cars class, i cannot assert that that class represents a single car or a collection of cars..

Also, you can find acomphreensible Enumerator tutorial here. Hope this helps ;)
