还是一样的问题
代码中存在未定义的部分和空白行，导致问题。让我们改进代码。你需要定义按钮布局，同时修正运算符和按钮之间的关系。
以下是改进后的代码：

)
scene = cocos.scene.Scene(Calculator())
cocos.director.director.run(scene)
以上修改内容：
[*]定义了 button_layout 来布局按钮。
[*]定义了一个运算符集合 operators 来区分运算符按钮。
[*]在添加按钮时，修正了按钮颜色的定义。
[*]将颜色改为RGBA格式以确保颜色正确。
这样代码应该可以正常运行。如果仍然有问题，请告诉我！

修改内容：
- 定义了 `button_layout` 来布局按钮。
- 创建了 `Menu` 并将 `MenuItem` 添加到 `Menu` 中。
- 修正了按钮颜色和位置的定义。

抱歉，之前的实现有问题。让我们重新编写一个简易计算器代码，确保使用 `cocos2d` 编写并且符合规范。
以下是一个简易计算器代码示例：
import cocos
from cocos.layer import ColorLayer
from cocos.text import Label
from cocos.menu import Menu, MenuItem, CENTER
# 颜色配置（使用RGB三元组）
DISPLAY_COLOR = (40, 40, 40) # 显示屏背景
BUTTON_COLOR = (80, 80, 80) # 普通按钮
OPERATOR_COLOR = (255, 165, 0) # 运算符按钮
CLEAR_COLOR = (255, 69, 0) # 清除按钮
TEXT_COLOR = (255, 255, 255) # 文字颜色（RGB格式）
class Calculator(cocos.layer.Layer):
is_event_handler = True
def __init__(self):
super(Calculator, self).__init__()
self.current_input = "0"
self.create_display()
self.create_buttons()
def create_display(self):
# 显示屏背景
display_bg = ColorLayer(*DISPLAY_COLOR, 255)
display_bg.width = 400
display_bg.height = 100
display_bg.position = (40, 450)
self.add(display_bg)
self.display_label = Label(
"0",
font_name="Arial",
font_size=48,
color=(TEXT_COLOR + (255,)),# 确保使用RGBA格式
anchor_x="right",
anchor_y="center",

)
self.display_label.position = (430, 500)
self.add(self.display_label)

if label == "C":
color = CLEAR_COLOR
btn_bg = ColorLayer(*color, 255)
btn_bg.width = 80
btn_bg.height = 80
btn_bg.position = (x, y)
self.add(btn_bg)
item = MenuItem(
label, self.on_button_pressed
)
item.position = x + 40, y + 40
buttons.append(item)

menu.create_menu(buttons, layout_strategy=fixedPositionMenuLayout(buttons))
self.add(menu)
def on_button_pressed(self, label):
if label == 'C':
self.current_input = "0"
elif label == '=':
try:
self.current_input = str(eval(self.current_input))
except:
self.current_input = "Error"
else:
if self.current_input == "0":
self.current_input = label
else:
self.current_input += label
self.update_display()
def update_display(self):
self.display_label.element.text = self.current_input
if __name__ == "__main__":
cocos.director.director.init(width=480, height=600, caption="Simple Calculator", resizable=False)
scene = cocos.scene.Scene(Calculator())
cocos.director.director.run(scene)
修正内容：
1. 使用 `Menu` 和 `MenuItem` 正确创建按钮。
2. 确保按钮位置和颜色正确。
3. 按钮的点击事件和显示更新逻辑。
这样，代码应该可以正常运行。如果你还有其他问题，请告诉我！

修改内容：
- 正确定义了 `button_layout`。
- 生成按钮并使用 `fixedPositionMenuLayout` 定位按钮。
- 修正了 `MenuItem` 对象的位置和逻辑。
这样，代码应该可以正常运行。如果你还有其他问题，请告诉我！
