python小恐龙代码

以下是Python小恐龙游戏的代码：

import pygame
import random

pygame.init()

# 游戏窗口大小
win_width = 800
win_height = 300

win = pygame.display.set_mode((win_width, win_height))
pygame.display.set_caption("小恐龙")

# 加载图片
dino_img = pygame.image.load("dino.png")
cactus_img = pygame.image.load("cactus.png")

# 小恐龙属性
dino_x = 50
dino_y = 220
dino_speed = 7
dino_jump = False
dino_jump_height = 80
dino_jump_count = dino_jump_height
dino_rect = dino_img.get_rect()

# 仙人掌属性
cactus_x = win_width
cactus_y = 230
cactus_speed = 10
cactus_rect = cactus_img.get_rect()

# 分数
score = 0
font = pygame.font.SysFont(None, 30)

# 游戏循环
run = True
while run:
    # 事件监听
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    # 背景颜色
    win.fill((255, 255, 255))

    # 小恐龙跳跃
    if dino_jump:
        if dino_jump_count >= -dino_jump_height:
            dino_y -= dino_jump_count / abs(dino_jump_count) * 5
            dino_jump_count -= 1
        else:
            dino_jump = False
            dino_jump_count = dino_jump_height

    # 仙人掌移动
    cactus_x -= cactus_speed
    if cactus_x < -cactus_rect.width:
        cactus_x = win_width
        score += 1
        cactus_speed += 1

    # 碰撞检测
    if dino_rect.colliderect(cactus_rect):
        run = False

    # 绘制小恐龙和仙人掌
    win.blit(dino_img, (dino_x, dino_y))
    win.blit(cactus_img, (cactus_x, cactus_y))

    # 绘制分数
    score_text = font.render("Score: " + str(score), True, (0, 0, 0))
    win.blit(score_text, (win_width - score_text.get_width() - 10, 10))

    # 更新窗口
    pygame.display.update()

pygame.quit()

注意：此代码仅适用于学习目的，实际游戏开发中还需要添加更多内容，如游戏开始界面、游戏结束界面、音效等。
