我正在制作一个简化版本agar.io http://agar.io.
目前，单元格被放置在网格背景上，就像游戏中一样。细胞吃食物，但只有圆圈内较小的正方形部分实际上吃食物（在我的程序中），当你足够大时，这一点是显而易见的。此外，当您按空格键时，它会将单元格分成 2 个较小的部分，几秒钟后它们会合并回来。这需要一个KEY_UP and K_SPACE事件，但我不确定如何实施。另外，一旦你的质量达到 34 左右，你可以按 w 射击你自己的一小部分，即质量约为 14 的较小细胞。
当细胞达到一定质量时，我尝试使用一堆 if 语句来减慢细胞速度。在游戏中，速度自然减慢。Here http://www.reddit.com/r/Agario/comments/3ae9vs/math_to_eat_or_not_to_eat/ and Here http://www.reddit.com/r/Agario/comments/34x2fa/game_mechanics_explained_in_depth_numbers_and/是描述游戏中使用的数学的来源。
这是我的代码：
import pygame, sys, random
from pygame.locals import *
# set up pygame
pygame.init()
mainClock = pygame.time.Clock()
# set up the window
width = 800
height = 600
thesurface = pygame.display.set_mode((width, height), 0, 32)
pygame.display.set_caption('')
bg = pygame.image.load("bg.png")
basicFont = pygame.font.SysFont('calibri', 36)
# set up the colors
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)
WHITE = (255, 255, 255)
BLUE = (0, 0, 255)
size = 10
playercolor = BLUE
# set up the player and food data structure
foodCounter = 0
NEWFOOD = 35
FOODSIZE = 10
player = pygame.draw.circle(thesurface, playercolor, (60, 250), 40)
foods = []
for i in range(20):
foods.append(pygame.Rect(random.randint(0, width - FOODSIZE), random.randint(0, height - FOODSIZE), FOODSIZE, FOODSIZE))
# set up movement variables
moveLeft = False
moveRight = False
moveUp = False
moveDown = False
MOVESPEED = 10
score = 0
# run the game loop
while True:
# check for events
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
if event.type == KEYDOWN:
# change the keyboard variables
if event.key == K_LEFT or event.key == ord('a'):
moveRight = False
moveLeft = True
if event.key == K_RIGHT or event.key == ord('d'):
moveLeft = False
moveRight = True
if event.key == K_UP or event.key == ord('w'):
moveDown = False
moveUp = True
if event.key == K_DOWN or event.key == ord('s'):
moveUp = False
moveDown = True
if event.type == KEYUP:
if event.key == K_ESCAPE:
pygame.quit()
sys.exit()
if event.key == K_LEFT or event.key == ord('a'):
moveLeft = False
if event.key == K_RIGHT or event.key == ord('d'):
moveRight = False
if event.key == K_UP or event.key == ord('w'):
moveUp = False
if event.key == K_DOWN or event.key == ord('s'):
moveDown = False
if event.key == ord('x'):
player.top = random.randint(0, height - player.height)
player.left = random.randint(0, width - player.width)
if event.type == MOUSEBUTTONUP:
foods.append(pygame.Rect(event.pos[0], event.pos[1], FOODSIZE, FOODSIZE))
foodCounter += 1
if foodCounter >= NEWFOOD:
# add new food
foodCounter = 0
foods.append(pygame.Rect(random.randint(0, width - FOODSIZE), random.randint(0, height - FOODSIZE), FOODSIZE, FOODSIZE))
if 100>score>50:
MOVESPEED = 9
elif 150>score>100:
MOVESPEED = 8
elif 250>score>150:
MOVESPEED = 6
elif 400>score>250:
MOVESPEED = 5
elif 600>score>400:
MOVESPEED = 3
elif 800>score>600:
MOVESPEED = 2
elif score>800:
MOVESPEED = 1
# move the player
if moveDown and player.bottom < height:
player.top += MOVESPEED
if moveUp and player.top > 0:
player.top -= MOVESPEED
if moveLeft and player.left > 0:
player.left -= MOVESPEED
if moveRight and player.right < width:
player.right += MOVESPEED
thesurface.blit(bg, (0, 0))
# draw the player onto the surface
pygame.draw.circle(thesurface, playercolor, player.center, size)
# check if the player has intersected with any food squares.
for food in foods[:]:
if player.colliderect(food):
foods.remove(food)
size+=1
score+=1
# draw the food
for i in range(len(foods)):
pygame.draw.rect(thesurface, GREEN, foods[i])
printscore = basicFont.render("Score: %d" % score, True, (0,0,0))
thesurface.blit(printscore, (495, 10))
pygame.display.update()
# draw the window onto the thesurface
pygame.display.update()
mainClock.tick(80)
再次，这是我想要解决的问题。
- 我希望按下空格键时单元格分成两部分。仅当单元格大小超过 30 时才会发生这种情况。
- 我希望当你按 W 时，细胞能够吐出自身的一小部分。吐出的部分将是设定的 15 质量。原来的单元格会小 15。多次点击W会吐出多个小球，直到原来的细胞质量达到20，此时就无法再吐出。
编辑：我尝试过做分裂的事情：
if event.key == K_SPACE:
pygame.draw.circle(thesurface, playercolor,(player.centerx,player.centery),int(size/2))
pygame.draw.circle(thesurface, playercolor,(player.centerx+size,player.centery+size),int(size/2))
输入上面的代码后，运行程序并按空格键，没有任何反应。该程序的表现就像我从未按下它一样。
