Python初学者求助：射箭游戏如何实现最高分存储与结束时展示

先修复你代码里的基础问题：重复导入turtle模块、t.pendown缺少调用括号、代码结构零散。然后在此基础上实现最高分存储功能——核心思路是用文本文件持久化保存最高分，游戏结束时读取文件对比当前分数，更新并展示。

完整实现代码 #

import turtle
import random

# 初始化游戏屏幕
screen = turtle.Screen()
screen.bgcolor("red")
screen.title("简易射箭游戏")

# 绘制箭靶及对应分数映射
target_turtle = turtle.Turtle()
target_turtle.pensize(4)
target_turtle.speed(5)
r = 180  # 最大环半径
y = -r
# 从外到内的环对应分数
score_map = {"white": 10, "grey": 20, "blue": 30, "red": 40, "yellow": 50}

for color in ["white", "grey", "blue", "red", "yellow"]:
    target_turtle.penup()
    target_turtle.goto(0, y)
    target_turtle.pendown()  # 修复原代码的括号缺失问题
    target_turtle.color(color)
    target_turtle.fillcolor(color)
    target_turtle.begin_fill()
    target_turtle.circle(r)
    target_turtle.end_fill()
    r -= 50
    y = -r
target_turtle.hideturtle()

# 射箭并计算当前得分
def shoot_arrow():
    arrow = turtle.Turtle()
    arrow.shape('arrow')
    arrow.penup()
    # 随机生成射箭起始位置
    start_x = random.randint(-100, 0)
    start_y = random.randint(0, 100)
    arrow.goto(start_x, start_y)
    # 朝靶心方向移动
    arrow.setheading(arrow.towards(0, 0))
    arrow.speed(3)
    arrow.forward(300)
    
    # 根据箭头落点计算得分
    final_x, final_y = arrow.pos()
    distance = ((final_x ** 2) + (final_y ** 2)) ** 0.5
    current_score = 0
    # 从内到外判断命中的环
    if distance <= 30:
        current_score = score_map["yellow"]
    elif distance <= 80:
        current_score = score_map["red"]
    elif distance <= 130:
        current_score = score_map["blue"]
    elif distance <= 180:
        current_score = score_map["grey"]
    elif distance <= 230:
        current_score = score_map["white"]
    
    arrow.hideturtle()
    return current_score

# 读取本地存储的最高分
def load_high_score():
    try:
        with open("high_score.txt", "r") as f:
            return int(f.read().strip())
    except (FileNotFoundError, ValueError):
        # 文件不存在或内容无效时，默认最高分为0
        return 0

# 将新最高分写入本地文件
def save_high_score(score):
    with open("high_score.txt", "w") as f:
        f.write(str(score))

# 游戏主流程
current_score = shoot_arrow()
high_score = load_high_score()

# 更新并判断是否刷新最高分
if current_score > high_score:
    high_score = current_score
    save_high_score(high_score)
    result_text = f"新纪录！当前得分：{current_score}，最高分：{high_score}"
else:
    result_text = f"当前得分：{current_score}，最高分：{high_score}"

# 在屏幕底部展示结果
text_turtle = turtle.Turtle()
text_turtle.hideturtle()
text_turtle.color("white")
text_turtle.penup()
text_turtle.goto(0, -250)
text_turtle.write(result_text, align="center", font=("Arial", 16, "bold"))

screen.exitonclick()

关键功能说明 #

• 基础问题修复：补全t.pendown()的调用括号，合并重复的箭头生成代码，优化整体结构。
• 得分逻辑：通过计算箭头落点到靶心的距离，判断命中的环数并匹配对应分数。
• 最高分持久化：
  • load_high_score()：读取本地的high_score.txt文件，首次运行文件不存在时默认最高分0。
  • save_high_score()：当当前得分超过历史最高分时，将新分数写入文件，确保下次打开游戏仍能读取历史最高分。
• 结果展示：用turtle的文本绘制功能，在屏幕底部清晰显示当前得分与最高分，刷新纪录时给出明确提示。
