我想在Python中使用pygame和IDLE開發一個簡單的遊戲。自從昨天以來,我已經通過各種渠道瞭解了這些語言(以及一般的編程語言),即使如此,我也遇到了一些問題和誤解。所以,如果任何人都可以請教我如何繼續(或者指出一些好的學習材料的方向),那麼我將非常感激。爲什麼PyGame追蹤圖像?
到目前爲止,我已經得到了一小部分代碼,這些代碼構成了我的遊戲理念的基礎,所以我會在這裏發佈它並列出我的一些問題。
import pygame
def main():
pygame.init()
logo = pygame.image.load("coolblack.jpg")
pygame.display.set_icon(logo)
pygame.display.set_caption("Battleship")
screenWidth = 800
screenHeight = 600
screen = pygame.display.set_mode((screenWidth, screenHeight))
bgd_image = pygame.image.load("grid.png")
#--------------------------------------------------------------------
#the image named 'image' should be above 'bgd_image' but below 'cv9'
#in fact, everything should be above bgd_image, especially 'cv9'
#--------------------------------------------------------------------
image = pygame.image.load("coolblack.jpg")
cv9 = pygame.image.load("ussessexcv9.gif").convert_alpha()
xposCv9 = 400
yposCv9 = 510
step_xCv9 = 1
step_yCv9 = 1
screen.blit(bgd_image, (0,0))
screen.blit(image, (400,300))
screen.blit(cv9, (xposCv9, yposCv9))
pygame.display.flip()
clock = pygame.time.Clock()
running = True
#---------------------------------------------
#I've got a pretty good idea (sort of) about
#what is happening in the section
#below this point, however it seems that
#the image 'cv9' creates a trail of itself
#every time it moves, so how could I make it
#so that it doesn't do so?
#---------------------------------------------
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
running = False
if xposCv9>screenWidth-64 or xposCv9<0:
step_xCv9 = -step_xCv9
if yposCv9>screenHeight-64 or yposCv9<0:
step_yCv9 = -step_yCv9
xposCv9 += step_xCv9
yposCv9 += step_yCv9
screen.blit(cv9, (xposCv9, yposCv9))
pygame.display.flip()
clock.tick(60)
if __name__=="__main__":
main()
非常感謝,這對我非常有幫助! – Moshi 2013-02-24 07:51:04
