要用编程画流星,你可以选择不同的编程语言和图形库来实现。以下是使用Python和Pygame库以及C语言和EasyX图形库的示例代码。

使用Python和Pygame库

导入必要的库

```python

import pygame

import random

import sys

```

初始化Pygame库

```python

pygame.init()

```

定义常量和流星类

```python

SCREEN_WIDTH = 800

SCREEN_HEIGHT = 600

NUM_METEORS = 10

MAX_SPEED = 10

MAX_LENGTH = 80

MIN_LENGTH = 40

class Meteor:

def __init__(self):

self.x = random.randint(0, SCREEN_WIDTH)

self.y = random.randint(-SCREEN_HEIGHT, 0)

self.speed = random.randint(1, MAX_SPEED)

self.length = random.randint(MIN_LENGTH, MAX_LENGTH)

def draw(self, surface):

pygame.draw.line(surface, (255, 255, 255), (self.x, self.y), (self.x - self.length, self.y + self.length), 2)

```

主循环

```python

screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))

clock = pygame.time.Clock()

while True:

for event in pygame.event.get():

if event.type == pygame.QUIT:

pygame.quit()

sys.exit()

screen.fill((0, 0, 0))

for meteor in meteors:

meteor.draw(screen)

meteor.x -= meteor.speed

if meteor.x + meteor.length < 0:

meteor.x = SCREEN_WIDTH

pygame.display.flip()

clock.tick(60)

```

使用C语言和EasyX图形库

包含必要的头文件

```c

include

include

include

include

```

定义结构体和初始化函数

```c

struct Star {

int x, y, r, speed, color;

};

struct Meteor {

int x, y, speed;

};

void initStar(struct Star *star, int count) {

for (int i = 0; i < count; i++) {

star[i].x = rand() % 800;

star[i].y = rand() % 600;

star[i].r = rand() % 3 + 1;

star[i].speed = rand() % 5;

star[i].color = RGB(rand() % 256, rand() % 256, rand() % 256);

}

}

void initMeteor(struct Meteor *meteor, int count) {

for (int i = 0; i < count; i++) {

meteor[i].x = rand() % 800;

meteor[i].y = -1200;

meteor[i].speed = rand() % 3 + 1;

}

}

```
