学习 Python 之 Pygame 开发魂斗罗四继续编写魂斗罗1. 创建子弹类2. 根据玩家方向和状态设置子弹发射的位置(1). 站立向右发射子弹(2). 站立向左发射子弹(3). 站立朝上发射子弹(4). 蹲下发射子弹(5). 向斜方发射子弹(6). 奔跑时发射子弹(7). 跳跃时发射子弹3. 在玩家类中加入开火4. 修改主类实现玩家开火继续编写魂斗罗
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移动和跳跃下面我们来继续写魂斗罗。

1. 创建子弹类
发射子弹首先要有子弹类 我们来创建一下
import pygame
from Constants import *class Bullet(pygame.sprite.Sprite):def __init__(self, person):pygame.sprite.Sprite.__init__(self)self.images [loadImage(../Image/Bullet/bullet1.png)]self.index 0self.image self.images[self.index]# 速度self.xSpeed 1self.ySpeed 1self.rect pygame.Rect(person.rect)# 销毁开关self.isDestroy Falsedef move(self):self.rect.x self.xSpeedself.rect.y self.ySpeedself.checkBullet()def draw(self, window):window.blit(self.image, self.rect)def checkBullet(self):toDestroy Falseif self.rect.top 0 or self.rect.top 600:toDestroy Trueif self.rect.left 0 or self.rect.right 900:toDestroy Trueif toDestroy:self.isDestroy True2. 根据玩家方向和状态设置子弹发射的位置
由于玩家的方向和状态不一样所以玩家开火后子弹发射的位置也不一样
下面我们来看看角色状态和发射子弹的位置
(1). 站立向右发射子弹
(x,y) 是图片的位置我们计算出此状态下子弹发射的位置是 (x24,y11) 下面我们来设置一下
self.rect.x 24 * 2.5
self.rect.y 11 * 2.5
self.ySpeed 0
self.xSpeed 72.5是人物放大的倍数加载图像的时候把图像放大了2.5倍所以设置子弹发射位置的时候同样要乘以2.5
if person.isStanding:# 判断方向# 方向向右if person.direction Direction.RIGHT:# 向上if person.isUp:pass# 向右else:self.rect.x 24 * 2.5self.rect.y 11 * 2.5self.ySpeed 0self.xSpeed 7# 方向向左else:if person.isUp:passelse:passelif person.isSquating and not person.isWalking:if person.direction Direction.RIGHT:passelse:passelif person.isWalking:if person.direction Direction.RIGHT:if person.isUp:passelif person.isDown:passelse:passelse:if person.isUp:passelif person.isDown:passelse:passelif person.isJumping or person.state State.FALL:if person.direction Direction.RIGHT:passelse:pass(2). 站立向左发射子弹 self.rect.y 11 * 2.5

站立向右朝上发射子弹
self.rect.x 10 * 2.5
self.rect.y -1 * 2.5
self.ySpeed -7
self.xSpeed 0这里我微微调整了一下y的值方向向上所以子弹的y是逐渐减小的所以y速度是负数

4. 修改主类实现玩家开火
由于玩家类中的update()方法多了一个子弹列表的参数现在要修改主类
在主类中加入子弹列表
# 子弹
player1BulletList []修改run()函数把子弹列表传入update()函数
def run(self):while not self.isEnd:# 获取窗口中的事件self.getPlayingModeEvent()# 游戏场景和景物更新函数self.update(MainGame.window, MainGame.player1BulletList)# 更新窗口pygame.display.update()# 设置帧率self.clock.tick(self.fps)fps self.clock.get_fps()caption 魂斗罗 - {:.2f}.format(fps)pygame.display.set_caption(caption)else:sys.exit()修改update()函数
def update(self, window, player1BulletList):# 更新物体currentTime pygame.time.get_ticks()MainGame.allSprites.update(self.keys, currentTime, player1BulletList)drawPlayerOneBullet(player1BulletList)# 显示物体MainGame.allSprites.draw(window)创建显示子弹函数在类外创建
def drawPlayerOneBullet(player1BulletList):for bullet in player1BulletList:if bullet.isDestroy:player1BulletList.remove(bullet)else:bullet.draw(MainGame.window)bullet.move()完整的主类代码
import sys
import pygame
from Constants import *
from PlayerOne import PlayerOnedef drawPlayerOneBullet(player1BulletList):for bullet in player1BulletList:if bullet.isDestroy:player1BulletList.remove(bullet)else:bullet.draw(MainGame.window)bullet.move()class MainGame:player1 NoneallSprites Nonewindow None# 子弹player1BulletList []def __init__(self):# 初始化展示模块pygame.display.init()SCREEN_SIZE (SCREEN_WIDTH, SCREEN_HEIGHT)# 初始化窗口MainGame.window pygame.display.set_mode(SCREEN_SIZE)# 设置窗口标题pygame.display.set_caption(魂斗罗角色)# 是否结束游戏self.isEnd False# 获取按键self.keys pygame.key.get_pressed()# 帧率self.fps 60self.clock pygame.time.Clock()# 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MainGame.player1.rect.x 80MainGame.player1.rect.bottom 300# 把角色放入组中方便统一管理MainGame.allSprites pygame.sprite.Group(MainGame.player1)def run(self):while not self.isEnd:# 设置背景颜色pygame.display.get_surface().fill((0, 0, 0))# 游戏场景和景物更新函数self.update(MainGame.window, MainGame.player1BulletList)# 获取窗口中的事件self.getPlayingModeEvent()# 更新窗口pygame.display.update()# 设置帧率self.clock.tick(self.fps)fps self.clock.get_fps()caption 魂斗罗 - {:.2f}.format(fps)pygame.display.set_caption(caption)else:sys.exit()def getPlayingModeEvent(self):# 获取事件列表for event in pygame.event.get():# 点击窗口关闭按钮if event.type pygame.QUIT:self.isEnd True# 键盘按键按下elif event.type pygame.KEYDOWN:self.keys pygame.key.get_pressed()# 键盘按键抬起elif event.type pygame.KEYUP:self.keys pygame.key.get_pressed()def update(self, window, player1BulletList):# 更新物体currentTime pygame.time.get_ticks()MainGame.allSprites.update(self.keys, currentTime, player1BulletList)drawPlayerOneBullet(player1BulletList)# 显示物体MainGame.allSprites.draw(window)if __name__ __main__:MainGame().run()运行一下看看效果 哈哈完成了
