Question

对monogame很新（单词为android准确），但有一些youtube教程，这个过程相当轻松。我试图覆盖一些函数（从“XNA库项目”DLL）我可以覆盖所有函数就好了。但是当我尝试覆盖SpriteBatch中作为参数传递的任何内容时，我得到以下错误：

错误5'Parkour.Screens.EditorScreen.Draw（Microsoft.Xna.Framework.Graphics.SpriteBatch）'：找不到合适的方法来覆盖D：\ Data \ programming和这样的\ comps \ TIGsport \ XNA \ Parkour \ Parkour \ Parkour \ Screens \ EditorScreen.cs 117 30 ParkourAndroid

我绝对相信这个方法就在那里，因为XNA项目运行得很好。 Draw函数也会在单声道Android项目的自动更正中弹出。但奇怪的是，在我收到错误后，它似乎已经从自动更正中消失了。

这是保持to override功能的整个类，这样你们就可以确定没有错。

你们中间有很多无用的东西，但我想把它包括在内是为了完整。

我对另一个具有需要重写的Draw（SpriteBatch）函数的类有完全相同的问题。

Answer 1

原来我正在传递一个MonoGame spritebatch，其中库需要一个XNA spritebatch。我在MonoGame的单独项目中重新编译了库，所有问题都得到了解决。

Monogame;无法覆盖任何将SpriteBatch作为参数的方法
