對於monogame來說很新穎（對於Android來說是單精度的），但是對於一些YouTube教程來說，這個過程相當不痛。 我想重寫一些函數（從「XNA庫項目」的DLL）我可以覆蓋所有的功能就好了。但是，當我嘗試去駕馭任何通過在SpriteBatch作爲參數，我得到了如下錯誤：Monogame;不能覆蓋任何以SpriteBatch作爲參數的方法
Error 5 'Parkour.Screens.EditorScreen.Draw(Microsoft.Xna.Framework.Graphics.SpriteBatch)': no suitable method found to override D:\Data\programming and such\comps\TIGsport\XNA\Parkour\Parkour\Parkour\Screens\EditorScreen.cs 117 30 ParkourAndroid
我絕對肯定的方法是存在的，因爲XNA項目工作就好了。 Draw函數也會在android項目的mono中自動更正。但是奇怪的是，在我收到錯誤消息後，它似乎消失了自動更正。
這裏是整個類，它擁有重寫功能，所以你們可以肯定沒有什麼是錯的。

有很多沒用的東西在那裏爲你們的課，但我想包括它只是爲了完整起見。
我有另一個具有Draw（SpriteBatch）函數需要重寫的完全相同的問題。
'GameScreen'是否繼承'LoopContainer'一些沿線或包含它自己的'Draw（SpriteBatch spriteBatch）'方法？你不能在另一個類上「覆蓋」一個方法，但它們之間沒有任何關係。 –
你能否給我包含你的'GameScreen'的代碼？ –
我意識到我的代碼不是很清楚。是的，它繼承了GameScreen。 另一方面，我想我可能已經發現了什麼問題，但我不完全確定。我正在加載的dll已經使用XNA框架進行了編譯。也許我應該首先在一個monogame項目中編譯它？我猜基礎函數需要一個Microsoft SpriteBatch，而EditorScreen有一個MonoGame SpriteBatch參數？ – omgnoseat
