# Karel The Robot in Python
## 1.所需使用的模組

# coding=UTF-8

import turtle
import easygui
import math
import time

## 2.世界邊界設定

#Border position(must be integer)
TOPBORDER = 200
BOTTOMBORDER = -200
LEFTBORDER = -200
RIGHTBORDER = 200

## 3.記錄檔案

f = open("LOG.txt","w")#Ready to write LOG

## 4.內部其他設定

#Karel heading
RIGHT = 0
LEFT = 180
TOP = 90
BOTTOM = 270

Karel = turtle.Turtle()#Set turtle "Karel the Robot"
Candy = turtle.Turtle()#Set turtle "Candy"
Choices = ["forward","Turn Left","Reset Karel the Robot"]

## 5.記錄時間格式

def nowTime(mode):#Show Time as YY/MM/DD  hour:min:sec
now = time.localtime()
hour = now[3]
m = now[4]
sec = now[5]

if now[3] <= 9:
hour = "0"+str(now[3])
if now[4] <= 9:
m = "0"+str(now[4])
if now[5] <= 9:
sec = "0"+str(now[5])

if mode == 1:
return (str(now[0])+"/"+str(now[1])+"/"+str(now[2])+"  "+str(hour)+":"+str(m)+":"+str(sec))
if mode == 2:
return (str(hour)+":"+str(m)+":"+str(sec))

## 6.設定Karel

def setup(Karel,Candy,f):
#Setup Karel and Candy
Karel.shape("arrow")
Karel.color("blue")
print("Program: Set Karel shape to arrow")
f.writelines((nowTime(2)," Set Karel shape to arrow\n"))

turtle.register_shape("candy.gif")#Load candy image
print("Program: Load image(candy.gif)...")
f.writelines((nowTime(2)," Load image(candy.gif)\n"))

Candy.shape("candy.gif")
print("Program: Set Candy shape to candy.gif")
f.writelines((nowTime(2)," Set Candy shape to candy.gif\n"))

Karel.penup()
Candy.penup()

print("Program: Set Karel's position...")     
f.writelines((nowTime(2)," Set Karel's position\n"))  
Karel.goto(LEFTBORDER+50,BOTTOMBORDER+50)#Karel default position

print("Program: Set Candy's position...")
f.writelines((nowTime(2)," Set Karel's position\n")) 
if ((LEFTBORDER+25)-(RIGHTBORDER-25))%100 == 50:#Candy default position
Candy.goto((LEFTBORDER+RIGHTBORDER)/2,Candy.ycor())
else:
Candy.goto((LEFTBORDER+RIGHTBORDER)/2-25,Candy.ycor())


if ((TOPBORDER-25)-(BOTTOMBORDER+25))%100 == 50:
Candy.goto(Candy.xcor(),(TOPBORDER+BOTTOMBORDER)/2)
else:
Candy.goto(Candy.xcor(),(TOPBORDER+BOTTOMBORDER)/2-25)


Candy.pendown()
print("Program: Setup Done!")
f.writelines((nowTime(2)," Setup Done!\n"))

## 7.重置遊戲

def reset(Karel,Candy,f):
print("User: Reset Karel Robot.")
f.writelines((nowTime(2)," Reset Robot\n")) 
#Reset Karel and Candy to default
Karel.right(Karel.heading())#Karel face to 0 degree
Candy.showturtle()
Karel.penup()
Candy.penup()

print("Program: Reset Karel's position...")
f.writelines((nowTime(2)," Reset Karel's position\n")) 
Karel.goto(LEFTBORDER+50,BOTTOMBORDER+50)


print("Program: Reset Candy's position...")
f.writelines((nowTime(2)," Reset Candy's position\n"))

if ((LEFTBORDER+25)-(RIGHTBORDER-25))%100 == 50:#Candy default position
Candy.goto((LEFTBORDER+RIGHTBORDER)/2,Candy.ycor())
else:
Candy.goto((LEFTBORDER+RIGHTBORDER)/2-25,Candy.ycor())


if ((TOPBORDER-25)-(BOTTOMBORDER+25))%100 == 50:
Candy.goto(Candy.xcor(),(TOPBORDER+BOTTOMBORDER)/2)
else:
Candy.goto(Candy.xcor(),(TOPBORDER+BOTTOMBORDER)/2-25)
Candy.pendown()
print("Program: Reset Done!")
f.writelines((nowTime(2)," Reset Done\n"))

## 8.製作障礙物

def makeWall(f):
print("Program: Making Wall...")
f.writelines((nowTime(2)," Making Wall...\n")) 
#Prepare the wall
wall = turtle.Turtle()
wall.color("gray")
wall.penup()
wall.goto(LEFTBORDER+25,TOPBORDER-25)#Lower Left Hand corner is default position
wall.speed(10000)
wall.pensize(2)
wall.pendown()


LENGTH = abs(RIGHTBORDER-LEFTBORDER)
WIDTH = abs(TOPBORDER-BOTTOMBORDER)

for i in range(0, int(WIDTH/50)-1):#WIDTH
wall.pendown()
for j in range(0, int(LENGTH/50)-1):#LENGTH
for k in range(0,4):
#Each square 100*100pixel
wall.forward(50)
wall.right(90)
wall.goto(wall.xcor()+50, wall.ycor())
wall.penup()
wall.goto(LEFTBORDER+25,wall. ycor()-50)
wall.hideturtle()
print("Program: Make Wall Done!")
f.writelines((nowTime(2)," Make Wall Done!\n"))

## 9.偵測Karel碰撞牆壁

def hitWall(Karel,f):
if ((Karel.heading() == RIGHT and Karel.xcor()+50 == RIGHTBORDER) or 
(Karel.heading() == LEFT and Karel.xcor()-50 == LEFTBORDER) or 
(Karel.heading() == BOTTOM and Karel.ycor()-50 == BOTTOMBORDER) or
(Karel.heading() == TOP and Karel.ycor()+50 == TOPBORDER)):

easygui.msgbox("Oops! Hit the Wall!!","Karel Say:")
print("Karel: Hit the Wall. Position:"+str(Karel.pos())+" Heading: "+str(Karel.heading()))
f.writelines((nowTime(2)," Karel: Hit the Wall. Position:"+str(Karel.pos())+" Heading: "+str(Karel.heading())+"\n"))
return True

## 10.讓Karel向左轉

def turnLeft(Karel,f):
#Karel turn left
print("Karel: Turn Left. Position:"+str(Karel.pos()))
f.writelines((nowTime(2)," Karel: Turn Left. Position:"+str(Karel.pos())+"\n"))
Karel.left(90)

## 11.讓Karel向前走

def forward(Karel,f):
#Karel move forward 100 pixel, avoid Karel hit the wall
if not hitWall(Karel,f):        
print("Karel: Forward 50 pixels from Position:"+str(Karel.pos())+" Heading: "+str(Karel.heading()))
f.writelines((nowTime(2)," Karel: Forward 50 pixels from Position:"+str(Karel.pos())+" Heading: "+str(Karel.heading())+"\n"))
Karel.forward(50)

1~11為基本Karel的基本程式，以下為Karel進階程式:
