我的敌人中只有一个在射击子弹pygame

Question

所以我一直在努力做到当我的敌人.x <700时开始向玩家射击，但它对我不起作用，它仅对其中一个起作用，而对唯一一个起作用为敌人工作是敌人之一。我曾尝试使用与播放器相同的代码，但没有用，也查看了错误，但没有，也检查了缩进。

我的敌人1正在开枪，但我的其他敌人却不在

这是我的问题所在

# This is enemy bullets and when player press Spacebar they come
    for egun in eguns:
        if egun.x < 700 and egun.x > 0:
            egun.x -= egun.speed 
        else:
            eguns.pop(eguns.index(egun))
    for enemy in enemys:
        if enemy.x < 700 and etimer == 0:
            if len(eguns) < 30:
                eguns.append(enemybullets(round(enemy.x+enemy.width//2),round(enemy.y + enemy.height-24),(0,0,0)))

            etimer = 1

Class Names通常应使用CapWords约定（例如class Column::Iterator { private: Column* father; size_t index; public: Iterator(Column* father, size_t index) : father(father), index(index { } Iterator operator++() { Iterator i = *this; i.index++; return i; } Iterator operator++(int) { index++; return *this; } int32_t& operator*() { return (*father)[index]; } int32_t* operator->() { return &((*father)[index]); } bool operator==(const Iterator& other) { return father == other.father and index == other.index; } bool operator!=(const Iterator& other) { return not operator==(other); } }; -> import re equation = '30=10x-20' #Checking 'c = bx+a' or 'bx+a = c' x = re.match('[0-9]+=[0-9]+x+?-?[0-9]+',equation) if x: #print('True') output_1 = equation.split('=') c = int(output_1[0]) print('c = ',c) # checking the operator between bx and a #rhs = '[0-9]+x+?[0-9]+' y = re.match('[0-9]+x-?[0-9]+',output_1[1]) if y: #filter_b = ['x'] output_2 = output_1[1].split('-') a = int(output_2[1]) b = int(output_2[0].replace("x","")) print('a = ',a) print('b = ',b) else: print('False') else: print('False') ）。
实现一个单一的类c = 30 a = 20 b = 10 就足够了。图像是类的属性，图像文件名可以是构造函数的参数。

无论如何，主要的问题是，您只有1个全局变量class enemy。 class Enemy必须是类Enemy的属性：

btimer

btimer

Enemy
