学习 Python 之 Pygame 开发魂斗罗(五)
继续编写魂斗罗
在上次的博客学习 Python 之 Pygame 开发魂斗罗(四)中,我们完成了角色的移动和跳跃还有射击,由于博主没有射击的音效,所以我们下面直接来写地图场景的代码,那我们就开始吧。
下面是图片的素材

1. 加载地图
首先设置一下地图缩放的尺寸,在Constants.py中加入代码
# 地图放缩倍数
MAP_SCALE = 2.5
其次,在主类中加载地图图片,修改__init__()函数
# 读取背景图片
self.background = pygame.image.load('../Image/Map/第一关BG.png')
self.backRect = self.background.get_rect()
# 放大2.5倍
self.background = pygame.transform.scale(
self.background,
(int(self.backRect.width * MAP_SCALE),
int(self.backRect.height * MAP_SCALE))
)
# 设置地图初始位置
self.backRect.x = -1280
对于窗口而言,我们要把地图加载到 (-1280, 0) 的位置
地图加载以后,我们要把它显示出来,修改update()函数
def update(self, window, player1BulletList):
# 加载背景
window.blit(self.background, self.backRect)
# 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)
现在看看效果,来运行一下
此时可以看到,成功加载了地图
2. 修改角色尺寸和地面高度
我们可以发现,角色有一点大了,调整小一点,修改Constants.py中的代码
新增变量
# 玩家放缩倍数
PLAYER_SCALE = 1.9
修改加载图片函数,把其中的2.5改成我们设置的倍数
def loadImage(filename, hReverse = False):
image = pygame.image.load(filename)
if hReverse:
image = pygame.transform.flip(image, True, False)
rect = image.get_rect()
image = pygame.transform.scale(
image,
(int(rect.width * PLAYER_SCALE), int(rect.height * PLAYER_SCALE))
)
image = image.convert_alpha()
return image
再运行一下,看看效果
可以看到人物变小了,那么就设置成功了
然后我们跳跃一下试试
发现掉下去了,这是因为在falling()函数中,设置了高度
SCREEN_HEIGHT - GROUND_HEIGHT = 600 - 63 = 537
所以高度永远不会低于537,这次我们修改一下,把高度调整的高一点,即让人物站的高一点
修改地面高度为295
GROUND_HEIGHT = 295
修改falling()函数中的代码,直接改成GROUND_HEIGHT
我们再看看效果
这次不管怎么跳,也不会下去了
接下来我们设置一下出场动画
在玩家类中,修改角色的初始状态
改为掉落
接下来把角色的位置修改一下,修改主类创建角色的代码
这样就好啦
我们再运行一下,看看效果
可以看到,人物掉下来出场的

如果有不懂的小伙伴,可以私信我
3. 添加玩家镜头移动
在魂斗罗游戏中,当我们的人物移动到屏幕的一半时,地图会随着人物向右走,所以我要接下来要完成一下
在主类的__init__()函数中新增一个变量,用来记录玩家当前位置与屏幕中间位置的距离
# 摄像头调整
self.cameraAdaption = 0
接下来写一个函数用来调整地图中的景物坐标
def camera(self):
# 如果玩家的右边到达了屏幕的一半
if self.player1.rect.right > SCREEN_WIDTH / 2:
if not (self.backRect.x <= -3500 * MAP_SCALE):
# 计算出超过的距离
self.cameraAdaption = self.player1.rect.right - SCREEN_WIDTH / 2
# 让背景向右走这么多距离
self.backRect.x -= self.cameraAdaption
# 场景中的物体都走这么多距离
for sprite in MainGame.allSprites:
sprite.rect.x -= self.cameraAdaption
解释一下原理
玩家在移动时,向右移动,实际上是地图在向左移动
当玩家到达屏幕中间时,如果继续向右走,那么地图就应该向左走
下图橙色是窗口,我们可以看到玩家移动,实际上是地图向左移动
那么地图向左走多少呢?
我们计算一下,即
self.player1.rect.right > SCREEN_WIDTH / 2
使用玩家的右边减去屏幕的宽度,就可以得到地图向左走的长度
地图不移动情况下,人物会走到上图上面图红框的位置,但是为了让人物始终处于中间的位置,就让地图向左移动
if not (self.backRect.x <= -3500 * MAP_SCALE):
这个代码的意思是,如果到了地图边缘的位置,即使人物过了屏幕一半,也不会在移动了
在update()函数中调用
下面我们来运行一下,看看效果
我们可以看到地图在移动啦,如果想要向左移动,也可以设置一下
4. 修改子弹的发射位置
当我们开火时,会发现一个问题
子弹发出的位置要低于枪口的位置,需要修改一下代码
之前由于我们把人物放缩尺寸变成了1.9,而子弹中的人物放缩比例还是2.5,所以会出现子弹发射位置有偏差
我们修改子弹类代码,把其中的2.5全部改成 PLAYER_SCALE
修改后的子弹类__init__()函数
def __init__(self, person):
pygame.sprite.Sprite.__init__(self)
self.images = [
loadImage('../Image/Bullet/bullet1.png')
]
self.index = 0
self.image = self.images[self.index]
# 速度
self.xSpeed = 1
self.ySpeed = 1
self.rect = pygame.Rect(person.rect)
if person.isStanding:
if person.direction == Direction.RIGHT:
if person.isUp:
self.rect.x += 10 * PLAYER_SCALE
self.rect.y += -1 * PLAYER_SCALE
self.ySpeed = -7
self.xSpeed = 0

else:

self.xSpeed = 7
elif person.isDown:
self.rect.x += 21 * PLAYER_SCALE
self.rect.y += 20 * PLAYER_SCALE
self.ySpeed = 7
self.xSpeed = 7
else:
self.rect.x += 24 * PLAYER_SCALE
self.rect.y += 11 * PLAYER_SCALE
self.ySpeed = 0
self.xSpeed = 7
else:
if person.isUp:
self.rect.x += -3 * PLAYER_SCALE
self.rect.y += -1 * PLAYER_SCALE
self.ySpeed = -7
self.xSpeed = -7
elif person.isDown:

elif person.isJumping or person.state == State.FALL:
if person.direction == Direction.RIGHT:

self.rect.y += 8 * PLAYER_SCALE
self.ySpeed = 0
self.xSpeed = 7
else:
self.rect.x += -2 * PLAYER_SCALE
self.rect.y += 8 * PLAYER_SCALE
self.ySpeed = 0
self.xSpeed = -7
# 销毁开关
self.isDestroy = False
修改后,在运行一下,看看结果,子弹发射位置就正常了
