五、小白如何用Pygame制作一款跑酷类游戏（主角跳跃和滑行动作的实现）

---

---

前言

本篇主要实现通过向下键和向上键的释放让主角能够跳跃和滑行

---

一、添加主角的跳跃和滑行图片素材

图片放在了 主角跳跃和滑行素材

二、代码部分

1.在走路状态时按下按键发生状态变化

 #步行状态if self.state==0:if args[0] % 6 == 0:i = int(args[0] / 6)self.image=self.walk[i % len(self.walk)]self.rect.top = 400# 实现按下向上键实现跳跃状态#实现按下向下键实现滑行状态if keys[pygame.K_UP]:self.state = 2self.flag = args[0]elif keys[pygame.K_DOWN]:self.state=3self.flag = args[0]

2.主角跳跃部分

设置为状态2

在跳跃部分为了更加生动并且可以越过障碍物进行了四个阶段的操作
第一个阶段上升的像素大
第二个阶段上升的像素小
第三个阶段下降的像素小
第四个阶段下降的像素大

 elif self.state==2:#在跳跃部分为了更加生动并且可以越过障碍物进行了四个阶段的操作#第一个阶段上升的像素大#第二个阶段上升的像素小#第三个阶段下降的像素小#第四个阶段下降的像素大if args[0] - self.flag <=9:if args[0] % 9 == 0:i = int(args[0] / 9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top -= 120elif args[0] - self.flag >9 and args[0] - self.flag <=36:if args[0] % 9 == 0:i = int(args[0] / 9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top -= 40elif args[0] - self.flag >36 and args[0] - self.flag <=63:if args[0] % 9 == 0:i = int(args[0] /9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top += 40elif args[0] - self.flag >63 and args[0] - self.flag <=72:if args[0] % 9 == 0:i = int(args[0] /9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top += 120if args[0] - self.flag >72:self.state = 0

3.主角滑行部分

设置为状态3

            elif self.state==3:if args[0] % 10 == 0:i = int(args[0] /10)self.image = self.down[i % len(self.down)]self.rect.top = 480# self.rect.left += 35if args[0] - self.flag >= 75:self.state = 0

4.为了使得在跑步阶段也能够切换为滑行和跳跃

            elif self.state==1:#设置一定的动作时长 超出之后变为步行态if args[0]-self.flag>=12:self.state=0if args[0] % 6 == 0:i = int(args[0] / 8)self.image=self.run[i % len(self.run)]self.rect.top = 430#奔跑状态时的状态切换if keys[pygame.K_UP]:self.state = 2self.flag = args[0]elif keys[pygame.K_DOWN]:self.state=3self.flag = args[0]elif keys[pygame.K_RIGHT]:self.state = 1self.flag = args[0]

5.总结上述的完整代码

import pygameclass Myself(pygame.sprite.Sprite):def __init__(self):super(Myself, self).__init__()self.image = pygame.image.load('material/image/myself/walk/1.PNG').convert_alpha()self.walk = [pygame.image.load('material/image/myself/walk/{:d}.PNG'.format(i)).convert_alpha() for i inrange(1, 8)]self.run = [pygame.image.load('material/image/myself/run/{:d}.PNG'.format(i)).convert_alpha() for i inrange(1, 6)]self.jump = [pygame.image.load('material/image/myself/jump/{:d}.PNG'.format(i)).convert_alpha() for i inrange(1, 7)]self.down = [pygame.image.load('material/image/myself/down/{:d}.PNG'.format(i)).convert_alpha() for i inrange(1, 7)]self.rect = self.walk[0].get_rect()self.rect.top=400self.rect.left=200self.state = 0  # 初始状态是步行态self.flag = 0 #设置标志位 记录按键按下的时钟def update(self, *args):#将是否暂停传递if args[2]:self.image=pygame.image.load('material/image/myself/walk/1.PNG').convert_alpha()else:#人物状态传递keys = args[1]#这里选择按下右箭头 是奔跑状态if keys[pygame.K_RIGHT]:self.state=1self.flag=args[0]#步行状态if self.state==0:if args[0] % 6 == 0:i = int(args[0] / 6)self.image=self.walk[i % len(self.walk)]self.rect.top = 400# 实现按下向上键实现跳跃状态#实现按下向下键实现滑行状态if keys[pygame.K_UP]:self.state = 2self.flag = args[0]elif keys[pygame.K_DOWN]:self.state=3self.flag = args[0]#奔跑状态elif self.state==1:#设置一定的动作时长 超出之后变为步行态if args[0]-self.flag>=12:self.state=0if args[0] % 6 == 0:i = int(args[0] / 8)self.image=self.run[i % len(self.run)]self.rect.top = 430#奔跑状态时的状态切换if keys[pygame.K_UP]:self.state = 2self.flag = args[0]elif keys[pygame.K_DOWN]:self.state=3self.flag = args[0]elif keys[pygame.K_RIGHT]:self.state = 1self.flag = args[0]elif self.state==2:#在跳跃部分为了更加生动并且可以越过障碍物进行了四个阶段的操作#第一个阶段上升的像素大#第二个阶段上升的像素小#第三个阶段下降的像素小#第四个阶段下降的像素大if args[0] - self.flag <=9:if args[0] % 9 == 0:i = int(args[0] / 9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top -= 120elif args[0] - self.flag >9 and args[0] - self.flag <=36:if args[0] % 9 == 0:i = int(args[0] / 9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top -= 40elif args[0] - self.flag >36 and args[0] - self.flag <=63:if args[0] % 9 == 0:i = int(args[0] /9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top += 40elif args[0] - self.flag >63 and args[0] - self.flag <=72:if args[0] % 9 == 0:i = int(args[0] /9)self.image = self.jump[i % len(self.jump)]# self.rect.left += 20self.rect.top += 120if args[0] - self.flag >72:self.state = 0elif self.state==3:if args[0] % 10 == 0:i = int(args[0] /10)self.image = self.down[i % len(self.down)]self.rect.top = 480# self.rect.left += 35if args[0] - self.flag >= 75:self.state = 0

三、实现效果

按向上键实现跳跃

按向下键实现滑行
