我想在屏幕上显示“障碍物”类的每个对象。对象存储在列表obstacle_list
中。我没有收到错误消息,但窗口只是冻结,屏幕上没有显示任何对象。我想问题一定出在{
import pygame
import random
import time
import math
# Initialize pygame
pygame.init()
# Create window (width, height)
screen = pygame.display.set_mode(((800, 600)))
ScreenHeight = screen.get_height()
ScreenWidth = screen.get_width()
# Background picture
background = pygame.image.load("background.jpg")
# Title and Icon
pygame.display.set_caption("F22-Raptor Simulator")
icon = pygame.image.load("jet1.png")
pygame.display.set_icon(icon)
# Object List (obstacles)
obstacle_list = []
class Obstacle(object):
def __init__(self): # removed unused parameters
self.obstacleImg = 'rock.png' # pygame.image.load("rock.png")
self.obstacleX = random.randint(600, 700)
self.obstacleY = random.randint(0, ScreenHeight - 64)
self.obstacleX_change = random.uniform(-0.3, -0.2)
def __repr__(self):
return f'Obstacle(image={self.obstacleImg!r}, X={self.obstacleX}, Y={self.obstacleY}, change={self.obstacleX_change})'
def spawn_obstacle(self):
image = pygame.image.load(self.obstacleImg)
screen.blit(image, (self.obstacleX, self.obstacleY))
# Keep window running (Infinite-Loop)
running = True
# Timer
timer1_start = time.time()
timer1_current = 0
# Counter while-loop to display objects
count_object_display = 0
# While-Loop (Everything that takes place during the game is inside here)
while running:
timer1_current = time.time()
if timer1_current - timer1_start >= 1:
timer1_start = time.time() # Timer of start set to current time
obstacle = Obstacle() # Create instance of class obstacle
obstacle_list.append(obstacle)
print(obstacle)
# Insert Background
screen.blit(background, (0, 0))
# End game / close window
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
while count_object_display <= len(obstacle_list)-1:
obstacle_list[count_object_display].spawn_obstacle()
count_object_display += 1
if count_object_display > len(obstacle_list)-1:
count_object_display = 0
# Update after each iteration of the while-loop
pygame.display.update()
这里有一个无限循环:
输入while循环并将
count_object_display
设置为1
在下一行中,
1 > 0
因此您将count_object_display
设置回0
自从
0 <= 0
while循环永远运行我不知道您想在那里做什么,但可能只是使用一个简单的
