在上次的博客学习 Python 之 Pygame 开发魂斗罗八中我们加入了敌人但是敌人不能发射子弹而且也没有碰撞体接下来我们来实现一下
下面是图片的素材

1. 在子弹类中修改敌人发射子弹的位置
敌人和玩家的图片不一样所以发射子弹的位置就不一样
下面是敌人发射子弹的图片 通过这个图片我们就可以计算出发射子弹的位置了
我们修改子弹类代码
在__init__()函数中增加一个参数isEnemy用来指定这个子弹是不是敌人发射的
class Bullet(pygame.sprite.Sprite):def __init__(self, person, isEnemy False):pygame.sprite.Sprite.__init__(self)self.images [loadImage(../Image/Bullet/bullet1.png)]然后把下面红框框出的代码进行修改 def __init__(self, person, isEnemy False):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)if not isEnemy:if person.isInWater:self.waterPosition(person)else:self.landPosition(person)else:if person.direction Direction.RIGHT:self.rect.x 27 * PLAYER_SCALEself.rect.y 7 * PLAYER_SCALEself.ySpeed 0self.xSpeed 7else:self.rect.x -1 * PLAYER_SCALEself.rect.y 7 * PLAYER_SCALEself.ySpeed 0self.xSpeed -7# 销毁开关self.isDestroy False接下来来到敌人1类 打开下面框出的代码的注释 好我们现在运行一下游戏看看效果 没有报错信息但是没看到敌人的子弹这是为什么呢
原来是我们没有写显示敌人子弹的函数
2. 创建显示敌人子弹的函数
下面我们来写一下进入主类
在主类外面创建全局函数
def drawEnemyBullet(enemyBulletList):for bullet in enemyBulletList:if bullet.isDestroy:enemyBulletList.remove(bullet)else:bullet.draw(MainGame.window)bullet.move()该函数用来显示子弹并让子弹移动
之后在update()函数中调用 现在运行一下游戏 敌人确实发射子弹了
3. 解决敌人不会向下掉落的问题 我们走到桥边发现敌人没办法掉下去这不对我们需要解决这个问题
在主类外面写一个全局函数用来让检测敌人碰撞问题敌人下落是垂直方向的碰撞问题
def updateEnemyPosition():# 遍历全部敌人列表for enemy in MainGame.enemyList:# 创建一个复制t copy.copy(enemy)t.rect.y 1# 让复制的y加1看看有没有发生碰撞这里看的碰撞是enemyColliderGroup中的碰撞collide pygame.sprite.spritecollideany(t, MainGame.enemyColliderGroup)# 没有发生碰撞让敌人下落if not collide:enemy.rect.y 4enemy.isFalling True# 改变下落时的图片enemy.image enemy.rightFallImage if enemy.direction Direction.RIGHT else enemy.leftFallImageelse:# 如果与河发生碰撞表示敌人落到了水中那么敌人直接死亡if collide in MainGame.enemyRiverGroup:enemy.isDestroy Truet.rect.y - 1之后调用一下这个函数在主类的update()函数中加入该函数 然后我们给敌人加入下降时的图片
来到敌人1类在__init__()函数中加入下面的代码
self.rightFireImage loadImage(../Image/Enemy/Enemy1/fire.png)
self.leftFireImage loadImage(../Image/Enemy/Enemy1/fire.png, True)
self.rightFallImage loadImage(../Image/Enemy/Enemy1/fall.png)
self.leftFallImage loadImage(../Image/Enemy/Enemy1/fall.png, True)接下来运行一下游戏 我们看到敌人直接掉下去了这是为什么
4. 给敌人碰撞体组增加碰撞体
这是因为现在敌人碰撞体组中什么都没有敌人脚下是空的当地人出现后就直接会掉下去啦
接下来我们给敌人增加碰撞体 注意看这个图position one表示这是产生敌人的第一个地区之前我们在Constants.py中设置了这个变量记录着敌人产生的高度
我们给敌人增加碰撞体需要清楚哪些地方需要增加
2的位置需要吗不需要因为敌人不会向下跳 1的位置需要吗需要因为敌人一出来就会在这个地方
根据分析我们得到
1需要增加陆地碰撞体r1和r3需要增加河碰撞体
下面我们来添加一下
修改initLand()函数河initRiver()函数
先把这两个函数拿出来作为全局函数 修改代码
def initLand():land1 Collider(81, 119 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land2 Collider(400, 151 * MAP_SCALE, 96 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land3 Collider(640, 183 * MAP_SCALE, 33 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land4 Collider(880, 183 * MAP_SCALE, 33 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land5 Collider(720, 215 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land6 Collider(1040, 154 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land7 Collider(1600, 166 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land8 Collider(1120 * RATIO, 215 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land9 Collider(1650 * RATIO, 119 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land10 Collider(2185 * RATIO, 119 * MAP_SCALE, 8 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land11 Collider(2595 * RATIO, 215 * MAP_SCALE, 3 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land12 Collider(2770 * RATIO, 167 * MAP_SCALE, 2 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land13 Collider(2535 * RATIO, 87 * MAP_SCALE, 16 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land14 Collider(2950 * RATIO, 151 * MAP_SCALE, 7 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)land15 Collider(3185 * RATIO, 215 * MAP_SCALE, 6 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)MainGame.playerLandGroup pygame.sprite.Group(land1, land2, land3, land4, land5, land6, land7, land8, land9, land10,land11, land12, land13, land14, land15)eland1 Collider(81, 119 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)eland9 Collider(1650 * RATIO, 119 * MAP_SCALE, 5 * LAND_LENGTH * MAP_SCALE, LAND_THICKNESS * MAP_SCALE)MainGame.enemyLandGroup pygame.sprite.Group(eland1, eland9)MainGame.playerColliderGroup.add(MainGame.playerLandGroup)MainGame.enemyColliderGroup.add(MainGame.enemyLandGroup)def initRiver():river1 Collider(0, 215 * MAP_SCALE, 289 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE, (0, 0, 255))river2 Collider(880, 215 * MAP_SCALE, 255 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE, (0, 0, 255))river3 Collider(1680, 215 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE, (0, 0, 255))eRiver1 Collider(0, 215 * MAP_SCALE, 289 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE, (0, 0, 255))eRiver3 Collider(1680, 215 * MAP_SCALE, 737 * MAP_SCALE, LAND_THICKNESS * MAP_SCALE, (0, 0, 255))MainGame.playerRiverGroup pygame.sprite.Group(river1, river2, river3)MainGame.enemyRiverGroup pygame.sprite.Group(eRiver1, eRiver3)MainGame.playerColliderGroup.add(MainGame.playerRiverGroup)MainGame.enemyColliderGroup.add(MainGame.enemyRiverGroup)e开头的是敌人碰撞体这里我多加入了一些碰撞体为地图后面的陆地也增加了
我们在Constants.py中加入
RATIO 1.3571428571428572我其实不太确定地图中冲突的尺寸在图片中1000的位置应该是一个陆地但是在窗口中这个地方不是陆地里面有一个对应的系数我试了放大倍数2.5发现对不上所以我就想找一个系数1.3571428571428572但是这个系数也有问题窗口上面的图片的系数和下面的系数不一样
我觉得这个地方不需要明白能在地图中的对应位置设置碰撞体就行至于位置大家可以自己探索 把碰撞体加入不同的组
接下来修改camera()函数让敌人碰撞体也随地图移动而移动 之后运行一下游戏看看效果 我们可以看到敌人掉不下去了我们来到河边看看
哈哈敌人掉下去了
但是又遇到了新的问题敌人会出现多个叠加在一起看上去重合了
下面来修复一下
5. 解决敌人叠加在一起的问题
敌人出现重叠的问题是产生敌人时两个敌人产生的地方很近导致的
我们修改产生敌人的代码即可 也可以增加玩家速度
我们让这两个if语句只执行一次就行执行多次就会出现敌人重叠 把代码改成3试试 运行后发现问题解决了
现在敌人有了子弹有了下一步就是实现玩家死亡和子弹消灭敌人了
