1. 创建敌人2类
这次新加入一个敌人首先创建敌人2的类
class Enemy2(pygame.sprite.Sprite):def __init__(self, x, y, direction, currentTime):pygame.sprite.Sprite.__init__(self)self.r 0.0self.bulletPosition 0self.rightImage loadImage(../Image/Enemy/Enemy2/right.png)self.rightUpImage loadImage(../Image/Enemy/Enemy2/rightUp.png)self.rightDownImage loadImage(../Image/Enemy/Enemy2/rightDown.png)self.leftImage loadImage(../Image/Enemy/Enemy2/right.png, True)self.leftUpImage loadImage(../Image/Enemy/Enemy2/rightUp.png, True)self.leftDownImage loadImage(../Image/Enemy/Enemy2/rightDown.png, True)self.type 2if direction Direction.RIGHT:self.image self.rightImageelse:self.image self.leftImageself.rect self.image.get_rect()self.rect.x xself.rect.y yself.center self.rect.x self.rect.width / 2, self.rect.y self.rect.height / 2self.isDestroy Falseself.isFiring Falseself.life 1self.lastTime currentTimeself.n 0# 计算时间self.t 0这里设置了一下加载的图片还有一些必要的属性
下面是这个敌人的图片 这个敌人发射子弹的放心是玩家的中心所以我们要计算出玩家的中心也要计算出敌人的中心这样可以计算出玩家与敌人相距的x方向的距离和y方向的距离
所以我们要有一个计算敌人中心的函数
def getCenter(self):return self.rect.x self.rect.width / 2, self.rect.y self.rect.height / 2有了计算中心的函数现在就可以写draw()函数了
2. 编写敌人2类的draw()函数
这个敌人一共有6种状态下面是示意图
这六个姿势就是6个图片
敌人的枪口始终对着我们的中心位置因为在魂斗罗游戏中这个敌人发射的子弹是一直跟着玩家的玩家移动它就移动枪口的位置因此就有这6中姿势
下面我们首先计算出敌人和玩家的距离 我们通过图可以看出x和y分别都是用人物的中心进行计算而得来的
∠1是玩家与敌人中心连线与水平方向的夹角这个交的大小决定着敌人的姿势 这张图片中的蓝色线是45度的线所以我们把姿势定下来
当玩家在敌人左边时计算玩家与敌人的夹角如果大于45度敌人就是姿势6如果小于-45度敌人状态就是姿势5其他敌人的姿势就是通过这样的方法计算出来的
下面我们写代码
def draw(self, window: pygame.Surface, player: PlayerOne, currentTime):# 获取玩家中心playerCenter player.getCenter()# 获取敌人中心center self.getCenter()# 计算距离y playerCenter[1] - center[1]x playerCenter[0] - center[0]# 设置存放夹角的变量r 0# 当 x 0时此时玩家在敌人的正上方我们不做任何操作if x ! 0:# 如果玩家在敌人的正上方计算角度r math.atan(y / x) * 180 / math.pi# 设置变量用来记录敌人的姿势敌人的姿势就是发射子弹时的样子self.bulletPosition 1# 根据距离的正负关系判断玩家在敌人的左边还是右边if x 0:if -45 r 45:self.bulletPosition 2self.image self.rightImageelif r 45:self.bulletPosition 3self.image self.rightDownImageelif r -45:self.bulletPosition 1self.image self.rightUpImageelse:if -45 r 45:self.bulletPosition 5self.image self.leftImageelif r -45:self.bulletPosition 4self.image self.leftDownImageelif r 45:self.bulletPosition 6self.image self.leftUpImageself.r rwindow.blit(self.image, self.rect)代码中我写了注释这段代码的意思上面也说明明白了大概就是计算出玩家和敌人的x方向距离和y方向距离然后计算夹角根据夹角的度数设置敌人的姿势
现在关键的一步来了发射子弹的位置有了下面就是要思考如何让敌人对着玩家中心发射
我们来想一下在高中我们学过 路程 时间×速度现在我们知道了路程就是敌人和玩家中心的距离差要计算速度那么需要知道时间那么如何计算时间呢有了时间我们通过公式 速度 路程 / 时间 计算出速度了
我们可以把调用draw()函数的时间间隔记录下来把这个的平均值设置为时间
于是我们在构造函数中就有了这两个变量
self.n 0
# 时间
self.t 0n记录总的间隔数t记录当前间隔的平均值
下面是计算思路把每次调用该函数的时间间隔记录下来根据调用的次数计算出平均调用该函数的时间间隔这个时间间隔就作为子弹的发射速度
self.n 1
# 计算速度
total self.t * self.n
total total abs(currentTime - self.lastTime)
self.lastTime currentTime
self.t total * 1.0 / (self.n 1)首先我们把上次调用该函数的时间记录到lastTime中这次调用函数时的时间记录在currentTime 中通过函数参数把currentTime值传进来 total self.t * self.n 这句代码来计算总的时间间隔因为最后我们要求两次调用该函数间隔的平均值
其次我们使用下面的代码把总的时间间隔和求出来 total total abs(currentTime - self.lastTime) 之后 self.lastTime currentTime 记录当前的时间准备进行下一次计算
最后计算间隔的平均值 self.t total * 1.0 / (self.n 1) 举一个例子
第一次计算出调用该函数的时间间隔是7ms此时n 1t 7子弹的速度就设置为7
第二次计算出调用该函数的时间间隔是8ms此时我们要计算8和7的平均值此时 n 2, t (1 * 7 8) / 2 7.5所以此时的子弹速度为7.5
第二次计算出调用该函数的时间间隔是8ms此时我们还是要计算平均值于是有t 7.5 * 2 8/ 3这个结果还是记录为子弹的速度
以此类推每次都会更新这个间隔时间这个间隔时间就是子弹的速度
所以我们最后就计算出来了子弹的速度了
把代码写到draw()函数中就完成了draw()函数
def draw(self, window: pygame.Surface, player: PlayerOne, currentTime):self.n 1# 计算时间total self.t * self.ntotal total abs(currentTime - self.lastTime)self.lastTime currentTimeself.t total * 1.0 / (self.n 1)# 获取玩家中心playerCenter player.getCenter()# 获取敌人中心center self.getCenter()# 计算距离y playerCenter[1] - center[1]x playerCenter[0] - center[0]# 设置存放夹角的变量r 0# 当 x 0时此时玩家在敌人的正上方我们不做任何操作if x ! 0:# 如果玩家在敌人的正上方计算角度r math.atan(y / x) * 180 / math.pi# 设置变量用来记录敌人的姿势敌人的姿势就是发射子弹时的样子self.bulletPosition 1# 根据距离的正负关系判断玩家在敌人的左边还是右边if x 0:if -45 r 45:self.bulletPosition 2self.image self.rightImageelif r 45:self.bulletPosition 3self.image self.rightDownImageelif r -45:self.bulletPosition 1self.image self.rightUpImageelse:if -45 r 45:self.bulletPosition 5self.image self.leftImageelif r -45:self.bulletPosition 4self.image self.leftDownImageelif r 45:self.bulletPosition 6self.image self.leftUpImageself.r rwindow.blit(self.image, self.rect)3. 编写敌人越界消失函数
当敌人创建出来后我们没有消灭他就会随着玩家向右移动消失在玩家的窗口中为了方式程序中存在大量的无效的敌人数据我们要检查程序让那些离开窗口的敌人自动销毁
编写检查函数
def checkPosition(self, x, y):if abs(self.rect.x - x) 2000:self.isDestroy Trueelif abs(self.rect.y - y) 600:self.isDestroy True当然敌人1类也有该函数
4. 编写敌人开火函数
由于敌人2发射的子弹要对着玩家的方向发射这里我们要修改子弹类 把子弹的初始速度变为0
修改构造函数参数 enemyType 是敌人的类型类型不一样发射位置不一样
parameter是一些额外的参数敌人2发射子弹时这里面就是传入一些必要的信息用来计算
接下来将原来的逻辑进行修改 大部分代码没有改变加了一个if-else语句
下面我们来写敌人2的子弹逻辑代码
elif enemyType 2:self.index 0bulletPosition parameter[0]player parameter[1]playerCenter player.getCenter()if player.isDown or player.isSquating:# 下蹲、蹲下、在水中时让人物中心下移动下移动代表y坐标的值相加playerCenter (playerCenter[0], playerCenter[1] 8)elif player.isInWater:playerCenter (playerCenter[0], playerCenter[1] 15)t parameter[2]# t * 15r parameter[3]if bulletPosition 1:self.rect.x 19 * PLAYER_SCALEself.rect.y -1 * PLAYER_SCALEself.ySpeed - abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 2:self.rect.x 25 * PLAYER_SCALEself.rect.y 10 * PLAYER_SCALEs -1if r 0:s 1self.ySpeed s * abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 3:self.rect.x 25 * PLAYER_SCALEself.rect.y 25 * PLAYER_SCALEself.ySpeed abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 4:self.rect.x -1 * PLAYER_SCALEself.rect.y 25 * PLAYER_SCALEself.ySpeed abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 5:self.rect.x -1 * PLAYER_SCALEself.rect.y 10 * PLAYER_SCALEs 1if r 0:s -1self.ySpeed s * abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 6:self.rect.x -1 * PLAYER_SCALEself.rect.y -1 * PLAYER_SCALEself.ySpeed - abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / tself.xSpeed / 5self.ySpeed / 5
self.image self.images[self.index]完整的子弹类构造函数
def __init__(self, person, enemyType 0, parameter None):pygame.sprite.Sprite.__init__(self)self.images [loadImage(../Image/Bullet/bullet1.png)]self.index 0# 速度self.xSpeed 1self.ySpeed 1self.rect pygame.Rect(person.rect)# 类型0表示不是敌人if enemyType 0:if person.isInWater:self.waterPosition(person)else:self.landPosition(person)# 敌人1elif enemyType 1:self.index 0if 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# 敌人2elif enemyType 2:self.index 0# 从额外参数中获取敌人的姿势即子弹的发射位置bulletPosition parameter[0]# 获取玩家对象player parameter[1]# 获取玩家中心playerCenter player.getCenter()# 让人物中心下移if player.isDown or player.isSquating:# 下蹲、蹲下、在水中时让人物中心下移动下移动代表y坐标的值相加playerCenter (playerCenter[0], playerCenter[1] 8)elif player.isInWater:playerCenter (playerCenter[0], playerCenter[1] 15)# 获取子弹移动的时间t parameter[2]# t * 15# 获取敌人与玩家连线与水平方向的夹角r parameter[3]# 根据子弹的发射位置敌人的姿势计算敌人的发射子弹的位置和子弹的速度if bulletPosition 1:self.rect.x 19 * PLAYER_SCALEself.rect.y -1 * PLAYER_SCALE# 计算公式|x0 - x1| / t vself.ySpeed - abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 2:self.rect.x 25 * PLAYER_SCALEself.rect.y 10 * PLAYER_SCALE# s 表示方向这里可以直接根据r的大小计算出子弹的速度是减少还是增加# 减少表示向负方向移动s -1if r 0:s 1self.ySpeed s * abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 3:self.rect.x 25 * PLAYER_SCALEself.rect.y 25 * PLAYER_SCALEself.ySpeed abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 4:self.rect.x -1 * PLAYER_SCALEself.rect.y 25 * PLAYER_SCALEself.ySpeed abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 5:self.rect.x -1 * PLAYER_SCALEself.rect.y 10 * PLAYER_SCALEs 1if r 0:s -1self.ySpeed s * abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / telif bulletPosition 6:self.rect.x -1 * PLAYER_SCALEself.rect.y -1 * PLAYER_SCALEself.ySpeed - abs(self.rect.y - playerCenter[1]) * 1.0 / tself.xSpeed - abs(self.rect.x - playerCenter[0]) * 1.0 / tself.xSpeed / 5self.ySpeed / 5self.image self.images[self.index]# 销毁开关self.isDestroy False之后我们来写玩家2类的开火函数了
def fire(self, enemyBulletList, player):i random.randint(0, 30)if i 5:self.isFiring TrueenemyBulletList.append(Bullet(self, 2, (self.bulletPosition, player, self.t, self.r)))设置开火的频率开火就创建一个子弹对象把相应的额外参数传入
好至此就完成了敌人2类
5. 把敌人2加入地图进行测试
来到主类编写全局函数用来创建敌人2 def generateEnemy2(x, y):enemy Enemy2(x, y, MainGame.player1, pygame.time.get_ticks())MainGame.enemyList.append(enemy)MainGame.allSprites.add(enemy)MainGame.enemyGroup.add(enemy)之后在generateEnemy()函数中调用 这个代码就是在指定的位置上创建一个敌人2
if -2005 self.backRect.x -2000:if self.enemyBoolList[2]:self.enemyBoolList[2] FalsegenerateEnemy2(MainGame.player1.rect.x 540, 465)接下来运行一下游戏看看效果 出现了报错信息应该是子弹类的构造函数进行了修改所有创建子弹的函数都要修改我们下面一一进行修改
首先进入enemyUpdate()函数由于我们加入了敌人2所以调用draw()函数的时候要进行判断了因为敌人1和敌人2的draw()函数参数不一样 将代码进行修改
def enemyUpdate(enemyList, enemyBulletList):# 遍历整个敌人列表for enemy in enemyList:if enemy.type 1:if enemy.isDestroy:enemyList.remove(enemy)MainGame.allSprites.remove(enemy)MainGame.enemyGroup.remove(enemy)else:enemy.checkPosition(MainGame.player1.rect.x, MainGame.player1.rect.y)enemy.draw(pygame.time.get_ticks())enemy.move(pygame.time.get_ticks())enemy.fire(enemyBulletList)elif enemy.type 2:if enemy.isDestroy:enemyList.remove(enemy)MainGame.allSprites.remove(enemy)MainGame.enemyGroup.remove(enemy)else:enemy.checkPosition(MainGame.player1.rect.x, MainGame.player1.rect.y)enemy.draw(MainGame.window, MainGame.player1, pygame.time.get_ticks())enemy.fire(enemyBulletList, MainGame.player1)变化的地方就是敌人2的draw()函数和fire()函数多了一个参数
之后给敌人1类加入成员变量type
self.type 1我们再运行游戏看看问题 可以看到敌人发射子弹的方向一直向着玩家
但是还有个问题就是玩家屏幕向右移动的时候子弹会停下来
这应该是窗口移动时没让子弹也一起移动
我们修改一下mapObjectMove()函数加入下面的代码 理论上爆炸也应该加入进去我们没有加入我们把爆炸也一同加入
def mapObjectMove(self):for sprite in MainGame.allSprites:sprite.rect.x - self.cameraAdaptionfor collider in MainGame.playerColliderGroup:collider.rect.x - self.cameraAdaptionfor collider in MainGame.colliderStack:collider.rect.x - self.cameraAdaptionfor collider in MainGame.enemyColliderGroup:collider.rect.x - self.cameraAdaptionfor bullet in MainGame.enemyBulletList:bullet.rect.x - self.cameraAdaptionfor explode in MainGame.explodeList:explode.rect.x - self.cameraAdaption好接下来我们再运行一下游戏看看效果 可以看到子弹也会随着窗口移动而移动啦
我们现在就完了敌人2了下面就是加入其他敌人和BOSS了
