Movieclip不能自行移動

在我的遊戲中，你可能會注意到這個人不會自行移動。您必須單擊一次屏幕才能讓該人用箭頭鍵左右移動。

這是我使用，使該名男子的舉動文件。我在哪裏更改代碼以使遊戲正常工作，以便男士在「Go！」之後移動，而且您不必點擊屏幕。

我的另一個問題是：當你按「P」時，你可以暫停遊戲。但是，您可能會在通過再次按下「P」鍵取消暫停遊戲後注意到，計時器已關閉了您暫停的秒數。該代碼也是定時器的代碼。我在代碼中更改了哪些內容以使計時器正確運行，這意味着在暫停遊戲之後，它不會跳過暫停的秒數，而是從停止的位置繼續。

代碼不足。它在哪裏顯示「Go！」？你也沒有正確地清除移動的變量，我在向左移動時死亡，並且隨後的所有重試使得該人立即向左移動而無法取消移動。 – Vesper

關於使計時器工作排除暫停時間 - 不要使用'getTimer（）'來代替這個，而是測量在同一個var'currentTime'中傳遞的幀，如果暫停，不要增加var。 – Vesper

它看起來像我「更新」是你移動的人。這是從startGame調用的，它只在buttonClickHandler4和buttonClickHandler6（KeyboardEvent的綁定位置）中調用。所以我不會指望這個人移動，直到其中一個點擊處理程序被調用。也許調用startGame並綁定constructer中的關鍵事件？ – dhc

編輯：我想通了，通過此鏈接問題：http://www.trainingtutorials101.com/2010/10/keyboard-events-wont-work-unless-user.html

我不得不使用命令stage.focus = this集中在舞臺上我的影片剪輯的人，所以這樣它可以偵聽鍵盤事件，而我的鼠標點擊屏幕。

並刪除男人周圍的黃色矩形我使用了命令stage.stageFocusRect = false。

感謝@dhc和@Vesper的所有幫助。

你快樂工作了！ – dhc

這是太長的評論線程爲這個問題。在你調用buttonClickHandler4之後，你的鍵盤事件應該正常工作。

設置調試點或跟蹤語句，查看是否調用了buttonClickHandler4。添加相同的名稱以確保正在調用downKey和move。這應該縮小問題的範圍。

好吧我會嘗試，謝謝。 –

按鈕點擊處理程序4正在調用，以及downKey和移動，但問題是，您必須至少點擊一次屏幕才能讓該移動。 –

這是怎麼回事？ –
