Monogame不绘制png图像

Question

我正在尝试在单人游戏中将精灵绘制到屏幕上，但不起作用。不给出任何错误。我尝试了其他图像，它适用于它们。也许它与.png的图像有关？请帮帮我，我想不通

代码：

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;

namespace Test
{
    public class Game1 : Game
    {
        private GraphicsDeviceManager _graphics;
        private SpriteBatch _spriteBatch;
        
        Texture2D realisticSturgeonSprite;

        public Game1()
        {
            _graphics = new GraphicsDeviceManager(this);
            Content.RootDirectory = "Content";
            IsMouseVisible = true;
        }

        protected override void Initialize()
        {
            // TODO: Add your initialization logic here

            base.Initialize();
        }

        protected override void LoadContent()
        {
            _spriteBatch = new SpriteBatch(GraphicsDevice);

            
            realisticSturgeonSprite = Content.Load<Texture2D>("Sturgeon");
        }

        protected override void Update(GameTime gameTime)
        {
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
                Exit();

            // TODO: Add your update logic here

            base.Update(gameTime);
        }

        protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);
            Texture2D rect = new Texture2D(_graphics.GraphicsDevice, 80, 30);

            Color[] data = new Color[80 * 30];
            for (int i = 0; i < data.Length; i++) data[i] = Color.Chocolate;
            rect.SetData(data);

            Vector2 coor = new Vector2(10, 20);
            _spriteBatch.Begin();
            _spriteBatch.Draw(rect, coor, Color.White);
            _spriteBatch.Draw(realisticSturgeonSprite, new Vector2(50, 60), Color.White);
            _spriteBatch.Draw(sturgeonSprite, new Vector2(80, 90), Color.White);
            _spriteBatch.End();
            

            base.Draw(gameTime);
        }
    }
}

精灵：Lake_Sturgeon.png

如果我遗漏了任何内容，我可以在帖子中添加更多详细信息。

使用Monogame Pipline tool先将PNG文件处理成XNB文件更容易。最佳跨平台解决方案。

有时您可能需要直接加载 PNG。

将现有文件添加到 Visual Studio 中的项目。选择 PNG 文件。复制它。

在 Visual Studio 的属性下，设置“构建类型为无”和“如果较新则复制到输出”。

请注意，这只适用于桌面平台。

protected override void LoadContent()
        {
            _spriteBatch = new SpriteBatch(GraphicsDevice);

            
            realisticSturgeonSprite = Texture2D.FromFile(GraphicsDevice,@"Lake_Sturgeon.png"); 
  // you can add path if needed (copy to output option above doesn't need it)
        }


        protected override void Draw(GameTime gameTime)
        {
            GraphicsDevice.Clear(Color.CornflowerBlue);

            _spriteBatch.Begin();

            _spriteBatch.Draw(realisticSturgeonSprite, new Vector2(50, 60), Color.White);

            _spriteBatch.End();
           

            base.Draw(gameTime);
        }

像往常一样绘制纹理。
