【问题描述】:
我有一个类似 Agar.io 的测试游戏,其中方形玩家触摸“位”并成长。问题是位生成。该位每秒生成一次,并有自己的表面。但是,该程序不会将位(没有双关语)插入初始表面。
代码如下:
import pygame
import random
pygame.init()
clock = pygame.time.Clock()
display = pygame.display
screen = display.set_mode([640,480])
rect_x = 295
rect_y = 215
display.set_caption("Agar")
d = False
bits = []
size = 50
steps = 0
class Bit:
cscreen = display.set_mode([640,480])
circ = pygame.draw.circle(cscreen, (65, 76, 150), (random.randrange(40, 600), random.randrange(40, 440)), 5)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
d = True
if d == True:
break
# Fill background
screen.fill((5, 58, 0))
# Create player object
player = pygame.draw.rect(screen, (250, 197, 255), [rect_x, rect_y, size, size])
# Moving
if pygame.key.get_pressed()[pygame.K_UP]:
rect_y -= 2
if pygame.key.get_pressed()[pygame.K_DOWN]:
rect_y += 2
if pygame.key.get_pressed()[pygame.K_RIGHT]:
rect_x += 2
if pygame.key.get_pressed()[pygame.K_LEFT]:
rect_x -= 2
# Bit generation
if steps == 60:
new_bit = Bit()
bits.append(new_bit.circ)
screen.blit(new_bit.cscreen, (0,0))
steps = 0
steps += 1
# Collision detection
collision = player.collidelist(bits)
if collision != -1:
bits[collision].cscreen.fill((0,0,0,0))
# Make player larger
size += 10
# FPS limit
clock.tick(60)
# Refresh
display.flip()
附:没有错误信息。
提前致谢。
【问题讨论】:
-
你在任何地方打电话给
display.update()吗? -
我正在调用 display.flip(),够了吗?还是我必须这样做?
