学习 Python 之 Pygame 开发魂斗罗三继续编写魂斗罗1. 角色站立2. 角色移动3. 角色跳跃4. 角色下落继续编写魂斗罗
在上次的博客学习 Python 之 Pygame 开发魂斗罗二中我们完成了角色的创建和更新现在具体实现一下更新函数中的角色状态函数
1. 角色站立
在写角色站立函数时先把其他状态函数注释了方便测试
在角色站立函数中首先设置当前角色的状态
站立时其他状态都是False只有isStanding True
# 设置角色状态
self.isStanding True
self.isWalking False
self.isJumping False
self.isSquating False
self.isUp False
self.isDown False
self.isFiring False其次修改人物的速度站立时速度均为0
# 设置速度
self.ySpeed 0
self.xSpeed 0再次我们设置按键响应事件
# 按下A键
if keys[pygame.K_a]:# A按下角色方向向左self.direction Direction.LEFT# 改变角色的状态角色进入移动状态self.state State.WALK# 设置站立状态为False移动状态为Trueself.isStanding Falseself.isWalking True# 向左移动速度为负数这样玩家的x坐标是减小的self.xSpeed -PLAYER_X_SPEED
# 按下D键
elif keys[pygame.K_d]:# D按下角色方向向右self.direction Direction.RIGHT# 改变角色的状态角色进入移动状态self.state State.WALK# 设置站立状态为False移动状态为Trueself.isStanding Falseself.isWalking True# 向右移动速度为正数self.xSpeed PLAYER_X_SPEED
# 按下k键
elif keys[pygame.K_k]:# K按下角色进入跳跃状态但是不会改变方向self.state State.JUMP# 设置站立状态为False跳跃状态为True# 不改变移动状态因为移动的时候也可以跳跃self.isStanding Falseself.isJumping True# 设置速度速度为负数因为角色跳起后要下落self.ySpeed self.jumpSpeed
# 没有按下按键
else:# 没有按下按键角色依然是站立状态self.state State.STANDself.isStanding True# 按下w键
if keys[pygame.K_w]:# W按下角色向上改变方向状态self.isUp Trueself.isStanding Trueself.isDown Falseself.isSquating False
# 按下s键
elif keys[pygame.K_s]:# S按下角色蹲下改变方向状态并且蹲下状态设置为Trueself.isUp Falseself.isStanding Falseself.isDown Trueself.isSquating True完整的角色类

在主类中创建角色并放入pygame.sprite.Group中
class MainGame:player1 NoneallSprites None在__init__()函数中添加代码
# 初始化角色
MainGame.player1 PlayerOne(pygame.time.get_ticks())
# 设置角色的初始位置
# 这里设置为080可以实现一开始玩家掉下来的动画目前没有实现掉落所以直接设置为80300
# MainGame.player1.rect.x 80
# MainGame.player1.rect.bottom 0
MainGame.player1.rect.x 80
MainGame.player1.rect.bottom 300# 把角色放入组中方便统一管理
MainGame.allSprites pygame.sprite.Group(MainGame.player1)之后在循环中调用角色的update函数
为了方便我把物体的更新全部放在一起创建一个update()函数
在主类中添加函数
def update(self, window):# 更新物体currentTime pygame.time.get_ticks()MainGame.allSprites.update(self.keys, currentTime)# 显示物体MainGame.allSprites.draw(window)pygame.sprite.Group()中的物体可以统一更新这就是它的方便之处
因为魂斗罗中玩家移动的时候场景中的物体也是要移动的所以地图是一个长条状当玩家向右移动时实际上是地图向左移动玩家不动创建中的物体向左移动如果不把全部物体放到组中不好统一管理
完整的主类代码

原因在于角色一开始创建时的状态不对 当前没有实现falling()函数所以下落状态没有办法显示所以我们修改一下修改角色类中__init__()函数
# 设置角色的状态
self.state State.FALL 改为 self.state State.STAND改完后运行一下看看结果 按a和d键玩家会一直移动不会停下来 到此我们就写好了玩家站立函数了下面我们来写玩家移动函数

3. 角色跳跃
首先设置状态标志
# 设置标志
self.isJumping True
self.isStanding False
self.isDown False
self.isSquating False
self.isFiring False更新速度
self.ySpeed self.gravity跳跃后角色的y坐标是减少的所以速度原来是负数由于跳起到最高点速度一直减小所以这里我们设置了重力保证速度慢慢减少到0
根据时间决定是否显示下一张图片
if currentTime - self.runLastTimer 115:if self.upImageIndex 3:self.upImageIndex 1else:self.upImageIndex 0# 记录变换图片的时间为下次变换图片做准备self.runLastTimer currentTime设置按键响应事件
if keys[pygame.K_d]:self.direction Direction.RIGHTelif keys[pygame.K_a]:self.direction Direction.LEFT# 按下W键
if keys[pygame.K_w]:self.isUp Trueself.isDown False
elif keys[pygame.K_s]:self.isUp Falseself.isDown True# 当速度变为正数玩家进入下落状态
if self.ySpeed 0:self.state State.FALLif not keys[pygame.K_k]:self.state State.FALL完整jumping()函数代码
def jumping(self, keys, currentTime):跳跃# 设置标志self.isJumping Trueself.isStanding Falseself.isDown Falseself.isSquating Falseself.isFiring False# 更新速度self.ySpeed self.gravityif currentTime - self.runLastTimer 115:if self.upImageIndex 3:self.upImageIndex 1else:self.upImageIndex 0# 记录变换图片的时间为下次变换图片做准备self.runLastTimer currentTimeif keys[pygame.K_d]:self.direction Direction.RIGHTelif keys[pygame.K_a]:self.direction Direction.LEFT# 按下W键if keys[pygame.K_w]:self.isUp Trueself.isDown Falseelif keys[pygame.K_s]:self.isUp Falseself.isDown Trueif self.ySpeed 0:self.state State.FALLif not keys[pygame.K_k]:self.state State.FALL4. 角色下落

不要忘记打开注释 到现在我们实现了角色移动、跳跃啦下面就是发射子弹了
