当我的玩家对象与ExitBock对象发生碰撞时,我需要进行等级更改。
我的播放器对象(一半评论是我的语言,但我需要帮助的评论被翻译):
class Player(Entity):
def __init__(self, x, y):
Entity.__init__(self)
self.xvel = 0
self.yvel = 0
self.onGround = False
self.image = Surface = right_standing
self.rect = self.image.get_rect()
def update(self, up, down, left, right, running, platforms):
a = 0
if up:
# Pasokti tik ant zemes
if self.onGround: self.yvel -= 7
if down:
pass
if running:
self.xvel = 12
if left:
self.xvel = -5
self.image = left_standing
if right:
self.xvel = 5
self.image = right_standing
#BegimoAnim.play()
if not self.onGround:
# gravitacija + acceleracija
self.yvel += 0.3
# Max kritimo greitis
if self.yvel > 100: self.yvel = 100
if not(left or right):
self.xvel = 0
# Prieaugis X direkcijoje
self.rect.left += self.xvel
# daryti X axis collision
self.collide(self.xvel, 0, platforms)
# Prieaugis Y direkcijoje
self.rect.top += self.yvel
# Ar ore?
self.onGround = False;
# daryti Y axis collision
self.collide(0, self.yvel, platforms)
def collide(self, xvel, yvel, platforms):
for p in platforms:
if pygame.sprite.collide_rect(self, p):
if isinstance(p, ExitBlock): # I need help here: what I should enter here?
pass
if xvel > 0:
self.rect.right = p.rect.left
if xvel < 0:
self.rect.left = p.rect.right
if yvel > 0:
self.rect.bottom = p.rect.top
self.onGround = True
self.yvel = 0
if yvel < 0:
self.rect.top = p.rect.bottom
我尝试过做一些事情,但他们没有奏效。 我的ExitBlock类:
class ExitBlock(Platform):
def __init__(self, x, y):
Platform.__init__(self, x, y)
self.image.fill(Color("#0033FF"))
我的游戏周期:
while 1:
timer.tick(60)
for e in pygame.event.get():
if e.type == QUIT: raise SystemExit("QUIT")
if e.type == KEYDOWN and e.key == K_ESCAPE:
raise SystemExit("ESCAPE")
if e.type == KEYDOWN and e.key == K_UP:
up = True
if e.type == KEYDOWN and e.key == K_DOWN:
down = True
if e.type == KEYDOWN and e.key == K_LEFT:
left = True
if e.type == KEYDOWN and e.key == K_RIGHT:
right = True
if e.type == KEYDOWN and e.key == K_SPACE:
running = True
if e.type == KEYUP and e.key == K_UP:
up = False
if e.type == KEYUP and e.key == K_DOWN:
down = False
if e.type == KEYUP and e.key == K_RIGHT:
right = False
if e.type == KEYUP and e.key == K_LEFT:
left = False
#First try:
'''if player.rect.colliderect(Finish.rect):
currentLevel += 1
platforms, entities, players, finishes = load_level(currentLevel)
print(currentLevel)'''
#Second try:
'''if player.collide(ExitBlock):
currentLevel += 1
platforms, entities, players = load_level(currentLevel)'''
##background
for y in range(32):
for x in range(32):
screen.blit(bg, (x * 32, y * 32))
##Update player, draw everything else##
for e in entities:
screen.blit(e.image, camera.apply(e))
for player in players:
screen.blit(player.image, camera.apply(player))
for Finish in finishes:
screen.blit(Finish.image, camera.apply(Finish))
camera.update(player)
pygame.display.update()
player.update(up, down, left, right, running, platforms)
我的整个代码是here.
答案 0 :(得分:0)
正确的碰撞检测算法
pygame.sprite.spritecollide(player, finishes, False)
