在矩阵pygame中移动多个对象

如何解决在矩阵pygame中移动多个对象

好的，所以我尝试在 pygame 中分隔入侵者，我决定在屏幕中间以矩形形状对多个敌人进行 blit，我也想移动它们，首先我创建了一个类似于屏幕使用敌人的宽度和高度，我设法做到了，当我想让他们都移动但不知道我如何已经有了一个移动功能，它在一个类的实例上工作得很好，但现在我不知道了不知道如何在多个对象上执行此操作，期望创建大量实例，这可能不是最有效和最好的方法，这是我的代码：

绘制函数：

    def draw(self):

    tile_width = enemy1.enemyImg_resize.get_width()
    tile_height = enemy1.enemyImg_resize.get_height()
    enemy_grid = [
        [0,0],[0,1,0]
    ]
    # Note: The matrix wasn't created manually but using numpy zeros() function
    y1 = 0
    for row in enemy_grid:
        x1 = 0
        for tile in row:
            if tile == 1:
                screen.blit(self.enemyImg_resize,(x1 * tile_width,y1 * tile_height))

            x1 += 1
        y1 += 1

移动功能：

def move(self):
    # global variable enemy_vel was declared above and I don't usually use globals I kNow they bad 
    
    # enemy is a rect version of enemyImg_resize,The problem is that even move function is able to 
    # handle only one object and I have no idea how to transform it to be able to handle more and 
    # move all of the enemies
    Global enemy_vel
    self.enemy.x += enemy_vel
    if self.enemy.x == 0:
        enemy_vel = 1
        self.enemy.y += self.enemyImg_resize.get_height()
    elif self.enemy.x == width - self.enemyImg_resize.get_width():
        enemy_vel = -1
        self.enemy.y += self.enemyImg_resize.get_height()
