C# Xna SpriteBatch矩阵不会将精灵绘制到屏幕
我目前对我的Xna游戏1课程有一个问题。我已经将一个2D相机与它自己的独立类合并在一起，该类被称为矩阵的使用。我遇到的问题是draw方法，我使用了 : `spriteBatch.Begin（SpriteSortMode.BackToFront，BlendState.AlphaBlend，null，null，null，camera.TransformMatrix） 问题发生在案例方法更改绘制内容之后，例如，案例主菜单和播放似乎无法到达，或者坦白地说，无法绘制到屏幕上。我尝试在每个案例中放置一个单独的SpriteBatch.Begin方法，因此，在案例中使用SpriteBatch.end（）结束每个方法本身 我也尝试过，没有在update方法中调用translateCamera类，但也没有用 任何帮助都将不胜感激C# Xna SpriteBatch矩阵不会将精灵绘制到屏幕,c#,matrix,xna,C#,Matrix,Xna,我目前对我的Xna游戏1课程有一个问题。我已经将一个2D相机与它自己的独立类合并在一起，该类被称为矩阵的使用。我遇到的问题是draw方法，我使用了 : `spriteBatch.Begin（SpriteSortMode.BackToFront，BlendState.AlphaBlend，null，null，null，camera.TransformMatrix） 问题发生在案例方法更改绘制内容之后，例如，案例主菜单和播放似乎无法到达，或者坦白地说，无法绘制到屏幕上。我尝试在每个案例中放置一个单独
