python飛機大戰源碼，python項目——外星人入侵游戲
開發大型項目時，做好規劃后再動手編寫項目很重要。規劃可確保你不偏離軌道，從而提高項目成功的可能性。 下面來編寫有關游戲《外星人入侵》的描述，其中雖然沒有涵蓋這款游戲的所有細節，但能讓你清楚地知道該如何動手開發它。 在游戲《外星人入侵》中，玩家控制著一艘最初出現在屏幕底部中央的飛船。玩家可以使用箭頭鍵左右移動飛船，還可使用空格鍵進行射擊。游戲開始時，一群外星 人出現在天空中，他們在屏幕中向下移動。玩家的任務是射殺這些外星人。玩家將所有外星人都消滅干凈后，將出現一群新的外星人，他們移動的速度更快。只要有外星人

?
Windows系統中首先安裝pip
要安裝pip，請訪問pip · PyPI下載壓縮包
?把他放到你預先準備好的文件夾中，并解壓
python飛機大戰源碼、
解壓后安裝pip?
打開cmd,控制臺命令進入pip文件夾,在命令行窗口輸入python setup.py install
在python的文件夾中找到Scripts文件夾,如果在其中發現以上四個文件則表示安裝成功
pip的配置設置
用python入侵別人手機、打開資源管理器–>右鍵此電腦–>點擊屬性–>點擊高級系統設置–>點擊環境變量–>將Scripts文件夾的路徑添加到path變量中
?在命令行輸入pip，不報錯就成功了
使用安裝pygame
在命令行中輸入pip install ?pygame
python好玩的黑科技。
以上不會的可直接在pycharm中安裝
?
?在這里直接安裝pygame也可
外星蟲入侵地球游戲？
這里準備工作就做好了
直接上代碼
