我統一編寫了一個報紙應用程序，我正在使用 webKit 來顯示報紙。但是，當它按下電話按鈕時，我需要返回上一頁。有誰知道返回上一頁的 C# 代碼...我寫;if(Input.GetKeyButton(KeyCode.Escape)){ Applicaition.Quit(); // However it quits from the app. Not going back previous page...}謝謝

這是我正在使用的 webkit 腳本......所以當我按下電話按鈕返回報紙上的上一頁時我需要代碼......

歡迎來到堆棧溢出。據我所知，Unity 不支持任何官方的 WebKit。因此，如果您提供代碼的更多詳細信息，將會很有幫助。
對于您的問題，我認為您可以自己保留一個 url 堆棧來處理頁面控件。
Stack<string> openedPages = new Stack<string>();
// When user open another page, put current url into stack.
OnOpenPage()
{
openedPages.Push(_current_page_url);
}
// When user push the previous page button, pop the last opened page url
OnPreviousPageButton()
{
string lastUrl = openedPages.Pop();
_yourBrowser.Open(lastUrl);
}
