в настоящее время пытается оживить массив вражеских спрайтов для в игре я производить в C# с помощью XNA 4.0Анимационного массив
Используя этот анимационного код
namespace Rotationgame
{
class Animation
{
Texture2D texture;
Rectangle rectangle;
Vector2 position;
Vector2 origin;
Vector2 velocity;
int currentFrame;
int frameHeight;
int frameWidth;
float timer;
float interval = 150;
public Animation(Texture2D newTexture, Vector2 newPosition, int newFrameHeight, int newFrameWidth)
{
texture = newTexture;
position = newPosition;
frameHeight = newFrameHeight;
frameWidth = newFrameWidth;
}
public void Update(GameTime gameTime)
{
rectangle = new Rectangle(currentFrame * frameWidth, 0, frameWidth, frameHeight);
origin = new Vector2(rectangle.Width/2, rectangle.Height/2);
position = position + velocity;
if (Keyboard.GetState().IsKeyUp(Keys.F1))
{
AnimateRight(gameTime);
velocity.X = 0;
}
else if (Keyboard.GetState().IsKeyUp(Keys.F2))
{
AnimateLeft(gameTime);
velocity.X = -0;
}
else velocity = Vector2.Zero;
}
public void AnimateRight(GameTime gameTime)
{
timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds/2;
if (timer > interval)
{
currentFrame++;
timer = 0;
if (currentFrame > 1)
currentFrame = 0;
}
}
public void AnimateLeft(GameTime gameTime)
{
timer += (float)gameTime.ElapsedGameTime.TotalMilliseconds/2;
if (timer > interval)
{
currentFrame++;
timer = 0;
if (currentFrame > 1)
currentFrame = 0;
}
}
public void Draw(SpriteBatch spriteBatch)
{
spriteBatch.Draw(texture, position, rectangle, Color.White, 0f, origin, 1.0f, SpriteEffects.None, 0);
}
}
}
И этот код для массива
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
Animation[] invaders;
protected override void Initialize()
{
invaders = new Animation[13];
// TODO: Add your initialization logic here
base.Initialize();
}
protected override void LoadContent()
{
// Create a new SpriteBatch, which can be used to draw textures.
spriteBatch = new SpriteBatch(GraphicsDevice);
// Array of Space Invaders
invaders[0] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(400, 400), 115, 96);
invaders[1] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(427, 310), 115, 96);
invaders[2] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(427, 490), 115, 96);
invaders[3] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(490, 250), 115, 96);
invaders[4] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(490, 550), 115, 96);
invaders[5] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(580, 240), 115, 96);
invaders[7] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(580, 560), 115, 96);
invaders[8] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(670, 550), 115, 96);
invaders[9] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(670, 250), 115, 96);
invaders[10] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(730, 490), 115, 96);
invaders[11] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(730, 310), 115, 96);
invaders[12] = new Animation(Content.Load<Texture2D>("SpaceInvaderbefore"), new Vector2(757, 400), 115, 96);
}
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.CornflowerBlue);
spriteBatch.Begin();
// Drawing Invaders
foreach (Animation invader in invaders)
invaders.Draw(spriteBatch);
}
spriteBatch.End();
Все работает в коде в Visual Studio, однако я получаю сообщение об ошибке в методе Draw: «Ошибка 1« System.Array »не содержит определения для« Draw »и никакого метода расширения ' Draw ', принимающий первый аргумент типа «System.Array», можно найти (вам не хватает директивы использования или ссылки на сборку?) «
Любые идеи, что пошло не так?

В вашем цикле foreach в 'Draw (GameTime)' вам нужно сделать 'invader.Draw (spriteBatch)' - на данный момент у вас есть «захватчики», который является массивом, что дает ошибку. Это означает, что foreach 'invader' в' invaders' будет вызван элемент Draw. – VisualMelon
Как сторона, где вызывается 'spriteBatch.End()'? Из вашего кода похоже, что это не метод, и он должен быть в конце вашего метода Draw. – VisualMelon
О, весь код во втором окне Я только скопировал соответствующий код в массив, так как у меня слишком много кода, поэтому часть foreach я скопировал эту часть и часть spriteBatch.End(), которую я также скопировал, объясняет, почему это выглядит странно там –
