我正在用python创建一个有滚动背景的游戏,我无法让我的玩家移动。正如你所知,我们不允许使用类或精灵
def game():
running = True
backgrounX = 0
button = 0
movex = 0
movey = 0
player = image.load("images/player.gif")
def drawscene(screen,button,backx):
screen.fill((0, 0 , 0))
background = image.load("images/bc3.png") # Load image
bc = transform.scale(background, (1000, 700)) # Scale the image
screen.blit(bc, [backx, 0]) # To show image
screen.blit(bc, [backx + 1000, 0]) # For background to move
button_1 = Rect(0, 0, 100, 70)
draw.rect(screen, (0, 85, 255), button_1)
draw_text("Exit", font, (0, 0, 0), screen, 25, 25)
for e in event.get():
if e.type == MOUSEBUTTONDOWN:
if e.button == 1:
main_menu()
# Game loop
while running:
for e in event.get():
if e.type == QUIT:
quit()
sys.exit()
running = False
if e.type == KEYDOWN:
if e.key == K_LEFT or e.key == ord('a'):
movex = -1
if e.key == K_RIGHT or e.key == ord('d'):
movex = +1
if e.key == K_UP or e.key == ord('w'):
movey = -1
if e.type == KEYUP:
if e.key == K_LEFT or e.key == ord('a') or e.key == K_RIGHT or e.key == ord('d'):
movex = 0
if e.key == K_UP or e.key == ord('w'):
movey = 0
x += movex
y += movey
drawscene(screen, button, backgrounX)
screen.blit(player (movex, movey))
myClock.tick(60)
backgrounX -= 3 # background scroller speed
display.update()
这就是我到目前为止所尝试的,第40行出现了一个错误,显示为“赋值前引用的局部变量'x'。有人知道让我的球员移动的其他方法吗
玩家的位置是(
x
,y
),而不是(movex
,movey
)。此外,参数列表中缺少一个“,”:screen.blit(player (movex, movey))
当然,您必须在应用程序循环之前的某个地方定义
x
和y
