六、小白如何用Pygame制作一款跑酷类游戏（静态障碍物和金币的添加）

前言

本篇文章将主要介绍静态障碍物的添加，其中包括金币以及主角可以跨越的向上障碍物和需要滑行的向下障碍物。

---

一、图片素材的导入

创建存放金币图片的gold文件夹
创建存放障碍物图片的stone文件夹

二、代码部分

1.金币是一个动态的精灵，创建金币精灵类

代码如下：

import pygame
class Gold(pygame.sprite.Sprite):def __init__(self):super(Gold, self).__init__()self.image = pygame.image.load('material/image/gold/1.PNG').convert_alpha()self.images = [pygame.image.load('material/image/gold/{:d}.PNG'.format(i)).convert_alpha() for i inrange(1, 26)]self.rect = self.images[0].get_rect()self.rect.top=450self.loc=0def update(self, *args):if args[0] % 4 == 0:i = int(args[0] / 4)self.image=self.images[i % len(self.images)]

2.mian方法中导入金币精灵类和随机数包

from Gold import Gold
import random

3.创建两个存放障碍图片对象的数组

#存放向上的
uplist=[]
#存放向下的
downlist=[]
upadress=['up1.png','up2.png','up3.png','up4.png']
downadress=['platform1.png','platform2.png','platform3.png','platform4.png','platform5.png']
#根据图像的位置加入到相应的数组当中
for i in range(len(downadress)):stone_image_path= 'material/image/stone/'+downadress[i]stone_img_obj=pygame.image.load(stone_image_path).convert_alpha()downlist.append(stone_img_obj)
for i in range(len(upadress)):stone_image_path= 'material/image/stone/'+upadress[i]stone_img_obj=pygame.image.load(stone_image_path).convert_alpha()uplist.append(stone_img_obj)

4.因为金币不唯一，所以创建一个精灵族来存放所有的金币精灵

goldGroup = pygame.sprite.Group()

5.计划在右半边的时候加入静态的障碍（采用随机数随机添加金币和障碍物）

#于是在当右半边移动到左边尽头的时候确定下来接下来的对象#这里采用随机数的方法barrier = []for i in range(0,4):random_number = random.randint(1, 15)if 10 <= random_number <= 15:gold1=Gold()gold2=Gold()gold3=Gold()gold1.loc=i*barriarMargingold2.loc=i*barriarMargin+1*70gold3.loc=i*barriarMargin+2*70goldGroup.add(gold1)goldGroup.add(gold2)goldGroup.add(gold3)barrier.append(1)elif random_number == 1:barrier.append(2)elif random_number == 2:barrier.append(3)elif random_number == 3:barrier.append(4)elif random_number == 4:barrier.append(5)elif random_number == 5:barrier.append(6)elif random_number == 6:barrier.append(7)elif random_number == 7:barrier.append(8)elif random_number == 8:barrier.append(9)elif random_number == 9:barrier.append(10)if -1080<right<1080:for sprite in goldGroup:sprite.rect.left=sprite.loc+rightgoldGroup.draw(screen)goldGroup.update(index)for i in range(len(barrier)):if barrier[i]==2:a = uplist[0]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 465)elif barrier[i]==1:continueelif barrier[i]==3:a = uplist[1]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 460)elif barrier[i]==4:a = uplist[2]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 455)elif barrier[i]==5:a = uplist[3]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 460)elif barrier[i]==6:a = downlist[0]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 330)elif barrier[i]==7:a = downlist[1]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 350)elif barrier[i]==8:a = downlist[2]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 365)elif barrier[i]==9:a = downlist[3]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 350)elif barrier[i]==10:a = downlist[4]arect = a.get_rect()arect.topleft = (right + i*barriarMargin, 210)screen.blit(a, arect)#及时从金币精灵族移除不需要的金币精灵for goldsprite in goldGroup:if goldsprite.rect.right<=0:goldGroup.remove(goldsprite)
