XNA：对象未在屏幕上绘制

Question

我以使用 XNA 在屏幕上绘制纹理而闻名。我只是无法让它工作。我确实正确加载了纹理。

    protected override void Draw(GameTime gameTime)
    {
        spriteBatch.Begin(SpriteSortMode.Deferred, null, null, null, null, null,
            selectedLevel.GetCamera().getViewMatrix(new Vector2(1.0f)));

        graphics.GraphicsDevice.Clear(Color.Black);
        foreach (MovableObject movableObject in selectedLevel.movableObjects)
        {
            if (movableObject is Enemy)
            {
                Enemy enemy = (Enemy)movableObject;
                ThrowAttack attack = ((ThrowAttack)enemy.getAttack());
                if (attack != null && attack.getThrowObject() != null)
                {
                    attack.getThrowObject().Texture = TextureLoader.GetInstance().GetTexture(attack.getThrowObject().TextureName);
                    attack.getThrowObject().Animate(Direction.Right, gameTime);
                    attack.getThrowObject().Walk(Direction.Right, 2f);
                    attack.getThrowObject().Update(gameTime);
                    attack.getThrowObject().Draw(spriteBatch);
                }
            }
        }
spriteBatch.End();
base.Draw(gameTime);
}

抽中攻击对象：

public void Draw(SpriteBatch spriteBatch)
{
    spriteBatch.Draw(texture, position, SpriteRectangle, Color.White, 0f, Vector2.Zero, 1.0f, SpriteEffects.None, 0f);
}

上面.draw 方法中的纹理和位置变量有效。只是在 foreach 循环中没有特定的纹理。

有什么想法吗？

您的代码看起来是正确的，所以它可能正在被绘制。

确保没有其他东西（比如另一个精灵或背景）在它上面绘制。这将发生得如此之快，以至于它看起来根本没有被绘制。
