python中的Tkinter对象检测（不是冲突）

Question

对编程和尝试让我的移动方块检测宝藏随机产生在两个盒子之一

from Tkinter import *
import time
import random
window = Tk()
canvas = Canvas(window, width = 1200, height = 800, bg = 'yellow')
canvas.pack()
canvas.pack(padx = 10, pady = 10)

a1 = 120
a2 = 120
a3 = 60
a4 = 60
Lm1 = canvas.create_rectangle(a1, a2, a3, a4, fill = 'green')

b1 = 530
b2 = 530
b3 = 600
b4 = 600
Lm2 = canvas.create_rectangle(b1, b2, b3, b4, fill = 'green')

Tr1 = canvas.create_rectangle(85,85,85+10,85+10, fill = 'blue')
Tr2 = canvas.create_rectangle(560,560,560+10,560+10, fill = 'blue')

list1 = [Tr1, Tr2]

Treasure1 = random.choice(list1)

if Treasure1 == Tr1:
    Tr1 = canvas.create_rectangle(85,85,85+10,85+10, fill = 'blue')
    canvas.delete(Tr2)
if Treasure1 == Tr2:
    Tr2 = canvas.create_rectangle(560,560,560+10,560+10, fill = 'blue')
    canvas.delete(Tr1)

vx = 10.0
vy = 10.0

Ro1 = canvas.create_rectangle(20, 20, 20+10, 20+10)

def right():
    canvas.coords(Ro1,x1+vx,y1,x2+vx,y2)
    canvas.update()
    time.sleep(0.1)

def left():
    canvas.coords(Ro1, x1-vx,y1,x2-vx,y2)
    canvas.update()
    time.sleep(0.1)

def down():
    canvas.coords(Ro1, x1,y1+vy,x2,y2+vy)
    canvas.update()
    time.sleep(0.1)

def up():
    canvas.coords(Ro1, x1,y1-vy,x2,y2-vy)
    canvas.update()
    time.sleep(0.1)

for r in range(1, 12):
    x1,y1,x2,y2 = canvas.coords(Ro1)
    right()
for r in range(1,12):
    x1,y1,x2,y2 = canvas.coords(Ro1)
    down()
for r in range(1,5):
    x1,y1,x2,y2 = canvas.coords(Ro1)
    left()

这是我试过的，但没用，我想让它把宝藏拿走，如果它知道它在那里，然后向右移动，我不知道还能怎么做？在

没有理由创建两个正方形，然后在几行之后删除一个。只要创建一个你想要的。另外，你必须以某种方式跟踪坐标，或者每次移动时都要得到它们。下面的代码可以工作，但可能不是您想要的。我从帖子上看不出什么应该“向右移动”。希望这能让你朝着正确的方向开始。另外，在进一步进行GUI编程之前，先看看move而不是coordshttp://effbot.org/tkinterbook/canvas.htm，并考虑学习如何使用类。在

from Tkinter import *
import random

def right():
    canvas.coords(Ro1, ctr_list[1], ctr_list[2],
                       ctr_list[1]+10, ctr_list[2]+10)
##    canvas.update()
    ctr_list[0] += 1
    ctr_list[1] += 10
    ctr_list[2] += 10
    print ctr_list
    if ctr_list[0] < 12:
        window.after(500, right)
##    time.sleep(0.1)

window = Tk()
canvas = Canvas(window, width = 1200, height = 800, bg = 'yellow')
canvas.pack()
canvas.pack(padx = 10, pady = 10)
Button(window, text="Quit", command=window.quit).pack(side="bottom")

a1 = 120
a2 = 120
a3 = 60
a4 = 60
Lm1 = canvas.create_rectangle(a1, a2, a3, a4, fill = 'green')

b1 = 530
b2 = 530
b3 = 600
b4 = 600
Lm2 = canvas.create_rectangle(b1, b2, b3, b4, fill = 'green')

##Tr1 = canvas.create_rectangle(85,85,85+10,85+10, fill = 'blue')
##Tr2 = canvas.create_rectangle(560,560,560+10,560+10, fill = 'blue')

list1 = ["Tr1", "Tr2"]
Treasure1 = random.choice(list1)

if Treasure1 == "Tr1":
    print "TR1"
    ctr_list = [0, a1-30, a3+30]
else:
    print "Tr2"
    ctr_list = [0, b1+30, b3-30]


Tr = canvas.create_rectangle(ctr_list[1], ctr_list[2],
                       ctr_list[1]+10, ctr_list[2]+10, fill="blue")

Ro1 = canvas.create_rectangle(20, 20, 20+10, 20+10)
right()

window.mainloop()
