How to fix a TypeError: 'float' object is not iterable
How to fix a TypeError: 'float' object is not iterable
我试图解决我的代码中“blit 的无效位置”的问题，但是一旦我解决了另一个错误就出现了。 类型错误：'float' 对象不可迭代。我尝试将 int() 放在周围（当我指周围时，我的意思是我尝试的代码是：int(self.x) += int(self.changeX)）
这是代码，我已经按顺序排列了，意思是这是所有相关内容从代码到其他所有内容的顺序。
（简单示例。实际上还有很多。）：
class Enemy():
def __init__(self, enemyImg, enemyX, enemyY, enemyX_change, enemyY_change):
self.image = enemyImg
self.x = enemyX
self.y = enemyY
self.changeX = enemyX_change
self.changeY = enemyY_change
def move(self):
self.x += self.changeX
self.y += self.changeY
def draw(self):
screen.blit(self.image, (self.x, self.y))

enemyX_change = []
enemyY_change = []
enemies = []

#Making a list for all 5 enemies image, x value, y value, x value change, y value change. All variables are a seperate list
for i in range(number_of_enemies):

enemyX.append(random.randint(0, 736))

enemyImg、enemyX 和 enemyY 是列表。但是，Enemy 构造函数的参数必须是单个图像和敌人的 x 和 y 坐标。
您不需要列表 enemyImg、enemyX、enemyY、enemyX_change 和 enemyY_change。删除列表：

enemy = Enemy(enemyImg, x, y, 0.45, 0)
enemies.append(enemy)
请注意，您可以使用 enemies[i].x 和 enemies[i].y 而不是 enemyX[i] 和 enemyY[i]
来获取敌人的坐标
此外，你必须在应用程序循环中而不是在通风循环中移动和绘制敌人。
