给敌人碰撞体组增加碰撞体5.

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

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,

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

False):pygame.sprite.Sprite.__init__(self)self.images

[loadImage(../Image/Bullet/bullet1.png)]self.index

0self.image

person.isInWater:self.waterPosition(person)else:self.landPosition(person)else:if

person.direction

drawEnemyBullet(enemyBulletList):for

bullet

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

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

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,

没有发生碰撞让敌人下落if

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

self.rightFireImage

loadImage(../Image/Enemy/Enemy1/fire.png)

self.leftFireImage

loadImage(../Image/Enemy/Enemy1/fire.png,

True)

loadImage(../Image/Enemy/Enemy1/fall.png)

self.leftFallImage

loadImage(../Image/Enemy/Enemy1/fall.png,

True)接下来运行一下游戏

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

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

根据分析我们得到

MAP_SCALE)MainGame.playerLandGroup

land2,

MAP_SCALE)MainGame.enemyLandGroup

eland9)MainGame.playerColliderGroup.add(MainGame.playerLandGroup)MainGame.enemyColliderGroup.add(MainGame.enemyLandGroup)def

initRiver():river1

river3)MainGame.enemyRiverGroup

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

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

之后运行一下游戏看看效果
