問(wèn)題描述
我對(duì)面向?qū)ο缶幊痰睦斫庥悬c(diǎn)不穩(wěn)定,所以如果你有任何鏈接可以幫助解釋這些概念,我會(huì)很高興看到它們!
My understanding of Object Orientated Programming is a little shaky so if you have any links that would help explain the concepts it would be great to see them!
我已經(jīng)稍微縮短了代碼.基本原則是我有一個(gè)以主 Controller 類的實(shí)例開(kāi)始的游戲.當(dāng)游戲打開(kāi)時(shí),Popup 類被打開(kāi).事件發(fā)生如下:
I've shortened the code somewhat. The basic principle is that I have a game that starts with an instance of the main Controller class. When the game is opened the Popup class is opened. The events happens as follows:
- 點(diǎn)擊彈窗上的開(kāi)始按鈕
- 方法 start_click() 運(yùn)行
- 調(diào)用Controller實(shí)例中的start_game()方法
- 這又將原始控制器實(shí)例中的游戲狀態(tài)更改為真"
我的問(wèn)題在于第 3 步.我收到的錯(cuò)誤消息是:
My problem is with step 3. The error message I get is:
我想 StartPopUp 類中需要對(duì) Controller 類進(jìn)行一些引用.但我不太明白如何創(chuàng)建該參考?
I guess there needs to be some reference to the Controller class in the StartPopUp class. But I don't quite understand how to create that reference?
提前致謝!
推薦答案
可以這樣傳遞實(shí)例
在控制器中
這篇關(guān)于從現(xiàn)有實(shí)例調(diào)用方法的文章就介紹到這了,希望我們推薦的答案對(duì)大家有所幫助,也希望大家多多支持html5模板網(wǎng)!
