游戏规则
用pygame动画实现神庙逃亡类似的小游戏，当玩家移动的时候躲避子弹，如果子弹命中玩家或者名字龙都会减速，玩家躲避子弹使更多的子弹打在龙上，当玩家被龙抓到，则游戏输，如果龙被子弹减少速度，与玩家有一定的距离，则玩家获胜。
精灵类
class MySprite(pygame.sprite.Sprite):
def __init__(self, target):
pygame.sprite.Sprite.__init__(self)
self.master_image = None
self.frame = 0
self.old_frame = -1
self.frame_width = 1
self.frame_height = 1
self.first_frame = 0
self.last_frame = 0
self.columns = 1
self.last_time = 0
def _getx(self):
return self.rect.x
def _setx(self, value):
self.rect.x = value
X = property(_getx, _setx)
def _gety(self):
return self.rect.y
def _sety(self, value):
self.rect.y = value
Y = property(_gety, _sety)
def _getpos(self):
return self.rect.topleft
def _setpos(self, pos):
self.rect.topleft = pos
position = property(_getpos, _setpos)
def load(self, filename, width, height, columns):
self.master_image = pygame.image.load(filename).convert_alpha()
self.frame_width = width
self.frame_height = height
self.rect = Rect(0, 0, width, height)
self.columns = columns
rect = self.master_image.get_rect()
self.last_frame = (rect.width // width) * (rect.height // height) - 1
def update(self, current_time, rate=30):
if current_time > self.last_time + rate:
self.frame += 1
if self.frame > self.last_frame:
self.frame = self.first_frame
self.last_time = current_time
if self.frame != self.old_frame:
frame_x = (self.frame % self.columns) * self.frame_width
frame_y = (self.frame // self.columns) * self.frame_height
rect = pygame.Rect(frame_x, frame_y, self.frame_width, self.frame_height)
self.image = self.master_image.subsurface(rect)
self.old_frame = self.frame
def __str__(self):
return str(self.frame) + "," + str(self.first_frame) + \
"," + str(self.last_frame) + "," + str(self.frame_width) + \
"," + str(self.frame_height) + "," + str(self.columns) + \
"," + str(self.rect)
MySprite继承精灵类，因为在做动画时候，需要许多的参数，这里进行了初始化，master_image 图片的位置，frame、old_frame分别储存第一帧和上一帧的位置，frame_width和frame_height保存宽高，first和last保存帧的第一帧和最后一帧。columns保存列数。last_time时间变量。
X、Y、pos保存精灵的位置x和y的位置。
load载入，赋予对应精灵的值，(rect.width // width) * (rect.height // height) - 1，通过给定的图片的宽高除以参数的值，-1就是初始的位置是从0开始的。
update更新的时候，根据传入的时间和间隔频率，如果时间大于上次时间和间隔则改变帧数，如果帧数改变对应的图片位置也改变，实现动态变化。
加载龙
dragon = MySprite(screen)
dragon.load("dragon.png", 260, 150, 3)
dragon.position = 100, 230
group.add(dragon)
arrow_vel = 8.0
game_over = False
you_win = False
player_jumping = False
jump_vel = 0.0
while True:
framerate.tick(30)
ticks = pygame.time.get_ticks()
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
keys = pygame.key.get_pressed()
if keys[pygame.K_ESCAPE]:
sys.exit()
elif keys[pygame.K_SPACE]:
if not player_jumping:
player_jumping = True
jump_vel = -8.0
screen.blit(bg, (0, 0))
if not game_over:
group.update(ticks, 50)
group.draw(screen)
print_text(font, 350, 360, "Press SPACE to jump!")
if game_over:
print_text(font, 360, 100, "G A M E O V E R")
if you_win:
print_text(font, 330, 130, "YOU BEAT THE DRAGON")
else:
print_text(font, 330, 130, "THE DRAGON GOT YOU")
pygame.display.update()
加载龙，实现龙动画，这里没有龙的位移，玩家躲子弹或者命中子弹都会导致双方的x坐标减少，这里没使用对应的速度改变，减少游戏的开发难度。
加载子弹
def reset_arrow():
y = random.randint(250, 350)
arrow.position = 800, y
arrow = MySprite(screen)
arrow.load("flame.png", 40, 16, 1)
arrow.position = 800, 320
group.add(arrow)
子弹因为只有一个，如果击中则需要重置，这里写了重置子弹的函数便于调用，random.randint(250, 350)给子弹一个随机的高度。使游戏与变化。
添加玩家
player = MySprite(screen)
player.load("caveman.png", 50, 64, 8)
player.first_frame = 1
player.last_frame = 7
player.position = 400, 303
group.add(player)
player_start_y = player.Y
player_start_y记录玩家初始的y坐标判断玩家是否处于跳跃状态中。
碰撞事件
if not game_over:
arrow.X -= arrow_vel
if arrow.X < 40:
reset_arrow()
if pygame.sprite.collide_rect(arrow, player):
reset_arrow()
player.X -= 10
if pygame.sprite.collide_rect(arrow, dragon):
reset_arrow()
dragon.X -= 10
if pygame.sprite.collide_rect(player, dragon):
game_over = True
if dragon.X < -100:
you_win = True
game_over = True
if player_jumping:
player.Y += jump_vel
jump_vel += 0.5
if player.Y > player_start_y:
player_jumping = False
player.Y = player_start_y
jump_vel = 0.0
这里需要检验玩家、子弹和龙两两相碰的事件。
