Pygame Zero:创建多个

Question

我用Python和Pygame Zero创建了一个游戏。当用户达到200点时，屏幕上会出现一个按钮。当用户单击按钮（下一个级别）时，将显示一个新级别。我试着用gamemode=3和gamestart=1来管理它（参见代码）。但是当用户点击“下一级”时，什么也没有发生。那么，如何添加多个级别？你知道吗

Answer 1

我成功了。在endoflevel1函数中，有必要使用pygame事件处理程序来检查鼠标按钮是否被单击，以及是否与“下一级”图形的位置相匹配。这是正在运行的endoflevel1函数的代码。在endoflevel1函数中，不可能像在鼠标按下（pos）函数中那样使用“简单方法”来检查鼠标按钮是否被单击并与指定的图形/演员匹配：

def endoflevel1():
global score, gamemode, gamestart, level
screen.clear()
screen.fill("green")
screen.draw.text("Congratulations! You have successfully completed the 1st level!", topleft=(100,350), fontsize=30, color = "black")
nextlevel.draw()  
gamestart = 0
pygame.display.flip()
running = True
while (running):
    for event in pygame.event.get():  
        if event.type == pygame.MOUSEBUTTONDOWN:
            if  nextlevel.collidepoint(event.pos):
                score = 0
                gamemode = 3
                gamestart = 1
                level = 2
                running = False
