您好我对pygame很新,我正在尝试为用户在电脑屏幕上悬停而屏幕然后变成蓝色的游戏进行介绍,因此请注意当您按下它时游戏将开始。但是,蓝色矩形根本没有出现?顺便说一句,introScreen就像一个gif,但是由许多不同的框架构成。
这是我的代码:
import pygame
import pygame.gfxdraw
import threading
pygame.init()
width = 800
height = 600
fps = 30
clock = pygame.time.Clock()
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)
blue = (0, 0, 255)
screen = pygame.display.set_mode((width, height))
def introLoop():
while intro:
for i in range(0, 26):
clock.tick(8)
i = str(i)
introScreen = pygame.image.load("introScreen/" + i + ".gif")
introScreen = pygame.transform.scale(introScreen, (width, height))
screen.blit(introScreen, (30, 30))
pygame.display.flip()
def gameLoop():
while intro:
mouseX, mouseY = pygame.mouse.get_pos()
startRectArea = pygame.Rect(279, 276, 220, 128)
if startRectArea.collidepoint(mouseX, mouseY):
StartRect = pygame.draw.rect(screen, blue, (279, 276, 220, 128), 0)
pygame.display.update()
for event in pygame.event.get():
holder = 0
introThread = threading.Thread(target = introLoop)
gameThread = threading.Thread(target = gameLoop)
intro = True
introThread.start()
gameThread.start()
没有错误消息它只是不显示蓝色矩形?请帮助我在学校项目中需要这个。
要在PyGame中使用多线程,你需要考虑两件事:
在主线程(程序)中,您需要声明线程并初始化控制(状态)变量。立即启动“intro”线程并运行事件循环。
我建议至少实施pygame.QUIT
,它表示程序必须终止(run = False
)。
此外,可以连续检查鼠标是否在起始区域(inStartRect = startRectArea.collidepoint(*pygame.mouse.get_pos())
):
introThread = threading.Thread(target = introLoop)
gameThread = threading.Thread(target = gameLoop)
run = True
intro = True
inStartRect = False
startRectArea = pygame.Rect(279, 276, 220, 128)
introThread.start()
while run:
if intro:
inStartRect = startRectArea.collidepoint(*pygame.mouse.get_pos())
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
elif event.type == pygame.MOUSEBUTTONDOWN and inStartRect:
intro = False
在介绍线程中,必须绘制整个介绍屏幕,包括背景和蓝色开始区域。如果介绍完成(游戏开始),则在介绍线程结束时启动主游戏循环:
def introLoop():
i = 0
while run and intro:
clock.tick(8)
filename = "introScreen/" + str(i) + ".gif"
i = i+1 if i < 26 else 0
introScreen = pygame.image.load(filename)
introScreen = pygame.transform.scale(introScreen, (width, height))
screen.blit(introScreen, (30, 30))
if inStartRect:
pygame.draw.rect(screen, blue, (279, 276, 220, 128), 0)
pygame.display.flip()
gameThread.start()
当介绍线程终止时,游戏线程开始。所以游戏线程可以绘制游戏场景:
def gameLoop():
while run:
clock.tick(60)
screen.fill(red)
# [...]
pygame.display.flip()
clock.tick(60)
尝试直接将intro传递给introLoop
函数。使用args
参数将参数传递给线程...
introThread = threading.Thread(target=introLoop, args=(intro))
您还必须重新定义该功能:
def introLoop(intro):
尝试使用.convert()
转换要加载的图像
pygame.image.load("image file path").convert()
或尝试使用.convert_alpha()
将图像转换为图像
pygame.image.load("image file path").convert_alpha()
Pygame发现加载用.convert()
转换的图像更容易,更快,而使用.convert_alpha()
,它会转换图像的alpha图层(E.G. Transparency ...)希望这会有所帮助!
