pygame spritegroups需要的幫助

Question

我修改了pygame的Chimp例子，用圓圈和一條線代替了Chimp圖片，使用從圓圈中心繪製的繪製方法，還用一個10×10的黑色框代替了拳頭表面。

我的問題是這樣的。

當黑框（拳頭）拳打圓（黑猩猩），圓（黑猩猩）必須旋轉360度。它適用於在chimp類中描述的單個圓形精靈，但是當我創建多個精靈並將它們添加到sprite.group中時，只有創建的第一個精靈旋轉，而另一個圓形（Chimp）精靈不會'沒有迴應。任何人都可以請告訴我如何解決這個問題。我使用python的3倍和1.9的Pygame

Answer 1

答案在於punch方法：

def punch(self,target) : 
    if not self.punching: 
     self.punching = 1 
     hitbox = self.rect.inflate(-5,-5) 
     return hitbox.colliderect(target.rect) 

屬性self.punching設置爲1的第一個黑猩猩。對於所有其它的，則不再執行該塊，因爲self.punching已經是1

嘗試撤消縮進的最後兩行，而不是：

def punch(self,target) : 
    if not self.punching: 
     self.punching = 1 
    hitbox = self.rect.inflate(-5,-5) 
    return hitbox.colliderect(target.rect) 

雖然這增加了新的「功能」，你可以衝再次衝壓之前。
