pygame随机显示多个图像 [英] Pygame display multiple images randomly
问题描述
我正在使用pygame，并且能够在屏幕上绘制多条线.我用以下命令制作的:
I am working with pygame and I was able to draw multiple lines on a screen. I made with this command:
for x in range(60,940,20):
pygame.draw.line(screen, white, [x, 0], [x, 500], 1)
我现在需要在屏幕上绘制多个图像.我能够通过执行以下操作绘制一张图像:
I now need to draw multiple images on the screen. I was able to draw one image by doing:
player_two = pygame.image.load("player_two.png").convert()
player_two.set_colorkey(white)
while done == False:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
screen.blit(player_two, [60, 240])
pygame.display.flip()
clock.tick(20)
pygame.quit()
我需要在[60，0]，[220，475] #OR范围内在相同范围内但已设置坐标的情况下随机绘制此对象的多个.这两个实例都需要这些图像在x和/或y方向上在#范围内随机移动#图像大小(跳跃).
I need to draw multiple of this object EITHER randomly within a range of [60, 0], [220, 475] #OR within the same range but with set coordinates. BOTH instances I need these images to move #randomly within that range in either x and/or y direction with a distance of the size of the #image (jump).
推荐答案
创建多人游戏
import random
multi_players = []
multi_players_pos = []
player = pygame.image.load("player_two.png").convert()
player.set_colorkey(white)
#create 10 players 0...9
for i in range(10):
multi_players.append(player)
pos = [random.randint(60,220+1), random.randint( 0, 475+1)]
multi_players_pos.append(pos)
或加载player_0.png ... player_9.png:
multi_players = []
multi_players_pos = []
for i in range(10):
temp = pygame.image.load("player_"+str(i)+".png").convert()
temp.set_colorkey(white)
multi_players.append(temp)
pos = [random.randint(60,220+1), random.randint( 0, 475+1)]
multi_players_pos.append(pos)
绘制:
while done == False:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
for i in range(len(multi_players)):
screen.blit(multi_players[i], multi_players_pos)
pygame.display.flip()
clock.tick(20)
pygame.quit()
您更改玩家位置的方法相同.
The same way you can change players position.
但是更好的方法是使Player类具有所有需要的功能.
But better way is to make Player class with all needed function.
(它不是完整的代码-因此未经测试)
import random
class Player():
def __init__(self, image, x, y):
self.image = pygame.image.load(image).convert()
self.image.set_colorkey(white)
image_rect = image.get_rect()
self.rect = Rect(x, y, image_rect.width, image_rect.height)
def draw(self, screen):
screen.blit(self.image, self.rect.topleft)
def update(self):
# here change randomly positon
#--------------------------------------------
multi_players = []
#create 10 players 0...9
for i in range(10):
x, y = random.randint(60,220+1), random.randint( 0, 475+1)
multi_players.append(Player("player_"+str(i)+".png", x, y))
while done == False:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
# changes position
for player in multi_players:
player.update()
# draws
for player in multi_players:
player.draw(screen)
pygame.display.flip()
clock.tick(20)
pygame.quit()
完整的示例-如果按任意键(ESC除外)，图像将更改位置.
Full working example - if you press any key (except ESC) images change position.
我使用透明的PNG ball1.png，ball2.png，ball3.png，所以我不使用.convert()和.set_colorkey().
I use transparent PNG ball1.png, ball2.png, ball3.png so I don't use .convert() and .set_colorkey().
