我是新來的python/pygame類,我正在做一個遊戲。 所以我的問題是,我有一個班,繪製太空船屏幕,但我需要以某種方式添加spacemove_x,spacemove_y
到他們的X和Y.我怎樣才能不斷更新變量從外面的類?
這些spacemove_x,spacemove_y
當用戶移動他的自己的飛船被定義
(我用spacemove_x,spacemove_y用於更新其他的東西的地方太像星星,因爲這個遊戲是從上往下看,所以當我提出我的飛船其他的事情應該取決於我的角色正在朝哪個方向前進)
所以spacemove_x,spacemove_y
總是更新它自我,但我怎麼能給這個信息類?

這是我如何創建宇宙飛船到我的遊戲:
spacecraft1 = spacecraftBOT(500,500,100,34,spacemove_x,spacemove_y)
那麼,如何給這個類更新spacemove_x,spacemove_y
?
我對Python不太熟悉,但是可以在'class spacecraftBOT'中添加另一個方法,就像'def update_spacemove(self,x,y)'等等,並且調用它沿着'spacecraft1.update_spacemove(1,2)'的方向行事? –
但是,這會有x和y的問題,因爲如果我需要說 '宇宙飛船1。update_spacemove(1,2)'wouldnt我需要redifine x,y然後船會去那些x和y? – cmdtvt
您可能必須更改變量名稱以符合代碼。另外,參數名不必與類中的變量相同/不同,但選擇合適的名稱是個好主意。 –
