pycharm用pygame写大球吃小球

好的，我可以给你一个简单的示例——大球吃小球的游戏。

首先，我们需要安装Pygame库。在PyCharm中，可以打开终端并输入以下命令来安装Pygame：

pip install pygame

然后，我们可以创建一个窗口并在窗口中绘制大球和小球。可以使用Pygame中的Surface和draw模块来实现：

import pygame
import sys
import random

pygame.init()

# 设置窗口大小和标题
size = width, height = 640, 480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('大球吃小球')

# 设置大球的初始位置和速度
big_ball_pos = [width // 2, height // 2]
big_ball_speed = [0, 0]

# 设置小球的数量和半径
num_balls = 10
min_radius = 10
max_radius = 30

# 生成小球的位置和速度
balls = []
for i in range(num_balls):
    radius = random.randint(min_radius, max_radius)
    x = random.randint(radius, width - radius)
    y = random.randint(radius, height - radius)
    speed = [random.randint(-5, 5), random.randint(-5, 5)]
    balls.append([x, y, speed, radius])

# 设置大球的半径和颜色
big_ball_radius = 50
big_ball_color = (255, 0, 0)

# 设置小球的颜色
ball_color = (0, 0, 255)

# 进入游戏循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    # 让大球移动
    big_ball_pos[0] += big_ball_speed[0]
    big_ball_pos[1] += big_ball_speed[1]

    # 判断大球是否碰到边界
    if big_ball_pos[0] < big_ball_radius or big_ball_pos[0] > width - big_ball_radius:
        big_ball_speed[0] = -big_ball_speed[0]
    if big_ball_pos[1] < big_ball_radius or big_ball_pos[1] > height - big_ball_radius:
        big_ball_speed[1] = -big_ball_speed[1]

    # 绘制大球和小球
    screen.fill((255, 255, 255))  # 设置背景色为白色
    pygame.draw.circle(screen, big_ball_color, big_ball_pos, big_ball_radius)

    for i in range(num_balls):
        x, y, speed, radius = balls[i]
        x += speed[0]
        y += speed[1]

        # 判断小球是否碰到边界
        if x < radius or x > width - radius:
            speed[0] = -speed[0]
        if y < radius or y > height - radius:
            speed[1] = -speed[1]

        # 判断大球是否吃掉了小球
        if (x - big_ball_pos[0]) ** 2 + (y - big_ball_pos[1]) ** 2 <= big_ball_radius ** 2:
            big_ball_radius += int(radius / 10)
            balls.pop(i)
            num_balls -= 1
            break

        balls[i] = [x, y, speed, radius]
        pygame.draw.circle(screen, ball_color, (x, y), radius)

    pygame.display.update()  # 更新窗口

最后，我们可以将以上代码整合在一起，并在PyCharm中运行：

import pygame
import sys
import random

pygame.init()

size = width, height = 640, 480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('大球吃小球')

big_ball_pos = [width // 2, height // 2]
big_ball_speed = [0, 0]

num_balls = 10
min_radius = 10
max_radius = 30

balls = []
for i in range(num_balls):
    radius = random.randint(min_radius, max_radius)
    x = random.randint(radius, width - radius)
    y = random.randint(radius, height - radius)
    speed = [random.randint(-5, 5), random.randint(-5, 5)]
    balls.append([x, y, speed, radius])

big_ball_radius = 50
big_ball_color = (255, 0, 0)

ball_color = (0, 0, 255)

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    big_ball_pos[0] += big_ball_speed[0]
    big_ball_pos[1] += big_ball_speed[1]

    if big_ball_pos[0] < big_ball_radius or big_ball_pos[0] > width - big_ball_radius:
        big_ball_speed[0] = -big_ball_speed[0]
    if big_ball_pos[1] < big_ball_radius or big_ball_pos[1] > height - big_ball_radius:
        big_ball_speed[1] = -big_ball_speed[1]

    screen.fill((255, 255, 255))

    pygame.draw.circle(screen, big_ball_color, big_ball_pos, big_ball_radius)

    for i in range(num_balls):
        x, y, speed, radius = balls[i]
        x += speed[0]
        y += speed[1]

        if x < radius or x > width - radius:
            speed[0] = -speed[0]
        if y < radius or y > height - radius:
            speed[1] = -speed[1]

        if (x - big_ball_pos[0]) ** 2 + (y - big_ball_pos[1]) ** 2 <= big_ball_radius ** 2:
            big_ball_radius += int(radius / 10)
            balls.pop(i)
            num_balls -= 1
            break

        balls[i] = [x, y, speed, radius]
        pygame.draw.circle(screen, ball_color, (x, y), radius)

    pygame.display.update()

运行后，程序会创建一个窗口并在窗口中绘制一个大球和多个小球，大球可以吃掉小球。按下窗口的关闭按钮或者按下Ctrl+C可以退出程序。
