我有一个函数加载一个精灵表,找到一个精灵块,然后将每个精灵放入一个列表.在将精灵附加到列表中之前,它会将其blit到屏幕上.一旦它完成加载精灵,它将遍历列表,随着它的进行blitting每个精灵.两组blits应该是相同的,但是从列表中删除第一个sprite,并且重复最后一个sprite.两组blits看起来像这样:
每个精灵按照它附加到列表的顺序进行blitting,从左到右,从上到下,所以第一个精灵是左上角,最后一个是右下角.
这是加载精灵的函数:
def assembleSprites(name, screen):
"""Given a character name, this function will return a list of all that
character's sprites. This is used to populate the global variable spriteSets"""
spriteSize = (35, 35)
spritesheet = pygame.image.load("./images/patchconsprites.png")
sprites = []
start = charCoords[name]
char = list(start)
image = pygame.Surface((35,35))
# load each sprite and blit them as they're added to the list
for y in range(5):
char[0] = start[0]
for x in range(9):
rect = (char[0], char[1], char[0]+spriteSize[0], char[1]+spriteSize[1])
image.blit(spritesheet, (0,0), rect)
image = image.convert()
colorkey = image.get_at((0,0))
image.set_colorkey(colorkey, RLEACCEL)
screen.blit(image, (x*40, y*40))
pygame.display.update()
sprites.append(image)
char[0] += spriteSize[0]+2
char[1] += spriteSize[1]+2
# check that the list was constructed correctly
count = 0
for y in range(6,11):
for x in range(9):
screen.blit(sprites[count], (x*40,y*40))
count += 1
pygame.display.update()
return sprites
有人看到我如何搞砸列表?
最佳答案
image.blit(spritesheet, (0,0), rect)
您没有在循环周围重新初始化图像,它仍然是您在上一次迭代中使用的表面,即已在列表中的表面.每次循环循环时,都会覆盖您在上一步中附加到列表中的精灵.
我建议在行之前而不是在循环开始之前抓取一个新的image = pygame.Surface((35,35)).
