Question

我目前正在创建一个RPG游戏，现在我想让角色去某些地方。当它到达那些地方时，该窗口应该关闭并且应该出现End（它在不同的文件中）。这样做的最佳方法是什么？我目前遇到的问题是保持检查变量给我进入某个区域的状态是False，如果它是真的，则应该执行其他代码。

以下是我目前的情况：

class player(object):
    def __init__(self, x, y):
        self.root = None
        self.x = x
        self.y = y

    def zeichne(self, root):
        self.root = root
        self.l1 = root.create_line(self.x-5, self.y-5, self.x+5, self.y+5,  width=2)
        self.l2 = root.create_line(self.x+5, self.y-5, self.x-5, self.y+5,  width=2)

    def configure(self, x, y):
        self.root.delete("all")
        self.x = x
        self.y = y
        self.root.create_line(self.x-5, self.y-5, self.x+5, self.y+5,  width=2)
        self.root.create_line(self.x+5, self.y-5, self.x-5, self.y+5,  width=2)

def go_fwd(event):
    areal.focus_set()
    me.configure(me.x, me.y-2)

def go_bwd(event):
    areal.focus_set()
    me.configure(me.x, me.y+2)

def go_left(event):
    areal.focus_set()
    me.configure(me.x-2, me.y)

def go_right(event):
    areal.focus_set()
    me.configure(me.x+2, me.y)

dw = tk.Tk()
dw.title('Erebos')

areal = tk.Frame(master=dw, width=20000, height=600, bg='black')
areal.pack_propagate(0)
areal.pack(fill=tk.BOTH, expand=bool(dw)-100)
areal.bind("<1>", lambda event: areal.focus_set())
dw.bind("<Up>", go_fwd)
dw.bind("<Down>", go_bwd)
dw.bind("<Left>", go_left)
dw.bind("<Right>", go_right)

playarea = tk.Canvas(width=800, height=500, master=areal, bg='white')
playarea.pack()

dw.mainloop()

我认为使用后台进程可能很有用，但有很多包，我真的很困惑。在这做什么，并使用背景包？

我希望我的问题是正确的。你必须在每一步都检查球员的位置。我建议您在每次移动时定义区域（例如go_right），您需要检查玩家是否在这些边界内。如果是True，您可以加载另一个脚本。这是一个快速而肮脏的解决方案：

def go_fwd(event):
    areal.focus_set()
    me.configure(me.x, me.y-2)
    check_if_player_enters_region(me)

def go_bwd(event):
    areal.focus_set()
    me.configure(me.x, me.y+2)
    check_if_player_enters_region(me)

def go_left(event):
    areal.focus_set()
    me.configure(me.x-2, me.y)
    check_if_player_enters_region(me)

def go_right(event):
    areal.focus_set()
    me.configure(me.x+2, me.y)
    check_if_player_enters_region(me)

def check_if_player_enters_region(player):
    ## Define your Areas here
    if(is_in_region(player, 20, 20, 10, 10)):
        print "enter region 1, load script xxx"
    if(is_in_region(player, 50, 50, 10, 10)):
        print "enter region 2, load script xxx"   

    playarea.create_rectangle(20,20,30,30, fill='blue') ## this is just for visualisation, delete this line
    playarea.create_rectangle(50,50,60,60, fill='blue') ## this is just for visualisation, delete this line

def is_in_region(player, x, y, width, height): # define region boundries
    if((player.x >= x and player.x <= x+width) and  ## check x boundries
       (player.y >= y and player.y-2 <= y+height)): ## check y boundries
        return True
    return False

dw = tk.tk()
dw.title('Erebos')

me = player(0,0)

areal = tk.Frame(master=dw, width=20000, height=600, bg='black')
areal.pack_propagate(0)
areal.pack(fill=tk.BOTH, expand=bool(dw)-100)
areal.bind("<1>", lambda event: areal.focus_set())
dw.bind("<Up>", go_fwd)
dw.bind("<Down>", go_bwd)
dw.bind("<Left>", go_left)
dw.bind("<Right>", go_right)

playarea = tk.Canvas(width=800, height=500, master=areal, bg='white')
playarea.pack()
playarea.create_rectangle(20,20,30,30, fill='blue') ## this is just for visualisation, delete this line
playarea.create_rectangle(50,50,60,60, fill='blue') ## this is just for visualisation, delete this line
me.zeichne(playarea)
dw.mainloop()

我只检查播放器的中心，通常你会检查＆＃34;框＆＃34;玩家。

在tkinter窗口中继续检查变量状态的最佳方法
