我想在屏幕上繪制一些調試信息，但這會導致渲染模型出現問題。我在互聯網上找到了一些解決方案，但它不起作用。也許我太笨了，但我不知道出了什么問題。這是繪制方法：    protected override void Draw(GameTime gameTime)    {        GraphicsDevice.Clear(Color.DarkCyan);        spriteBatch.Begin();        player.Draw(dt);        spriteBatch.DrawString(gamefont, "render Time :" + gameTime.ElapsedGameTime.TotalSeconds, new Vector2(0, 85), Color.White);        spriteBatch.End();        effect.View = player.view;        effect.Projection = player.projection;        effect.Texture = dirtTexture;        GraphicsDevice.SamplerStates[0] = SamplerState.PointClamp;        GraphicsDevice.BlendState = BlendState.Opaque;        GraphicsDevice.DepthStencilState = DepthStencilState.Default;        foreach (EffectPass p in effect.CurrentTechnique.Passes)        {            p.Apply();            effect.World = player.world;            GraphicsDevice.DrawPrimitives(PrimitiveType.TriangleList, 0, buffer.VertexCount / 3);        }        base.Draw(gameTime);    }這是它的樣子
