幕控制需求

幕控制的重要函數

幕模式函數

幕設定為大小可調

幕設定為全屏

幕資訊函數

小遊戲(伸縮型)

pygame.display.set_mode(r=(0,0), flags=0)

r是遊戲螢幕的分辨率，采用(width, height)方式輸入

• flags用來控制顯示類型，可用|組合使用，常用顯示标簽如下：

† pygame.RESIZABLE 視窗大小可調

† pygame.NOFRAME 視窗沒有邊界顯示

† pygame.FULLSCREEN 視窗全屏顯示

pygame.display.set_mode(r=(0,0), flags=0)

注意：每種顯示方式要配合相應的處理機制
