Drawing stick figure?

Expand Post »

well basically i have to draw a stick figure for which is my first question... i cant figure out how to draw a horizontal line and also a line at a angle for the legs... here is the code for the first one

def drawStickFigure():
from graphics import *
win = GraphWin("Stick figure")
head = Circle(Point(100, 60), 20)
head.draw(win)
body = Line(Point(100, 80), Point(100, 120))
body.draw(win)
arms= Line(Point(0, 100), Point(0, 100))
arms.draw(win)

for the second question i have to draw a circle which is at the centre of the graphics window. the user inputs the radius of the circle and the circle should come. But for some reasn my code doesnt seem to be working please help

def drawCircle():
x = input("please enter the radius of the circle: ")
centre= Point(100, 100)
circle1 = Circle(centre, x)
circle1.draw(win)

Re: Drawing stick figure?

I hope you are not stuck with an outdated module like graphics, which is a wrapper for Tkinter, written by some guy to sell his book. You are much better off using the Tkinter GUI toolkit directly and learn something you can actually use later on.

To say it bluntly, the module graphics is all candy and no meat!

Re: Drawing stick figure?

And it's not tough to do.

Python Syntax (Toggle Plain Text)
import Tkinter
 
root = Tkinter.Tk()
root.title('Canvas')
canvas = Tkinter.Canvas(root, width=450, height=450)
 
canvas.create_oval(100,50,150,100, fill='gray90')
 
x = 125
y = 175
stick = canvas.create_line(x, y-75, x, y)
 
diff_x = 25
stick_leg1 = canvas.create_line(x, y, x-diff_x, y+50)
stick_leg2 = canvas.create_line(x, y, x+diff_x, y+50)
 
y=145
stick_arm1 = canvas.create_line(x, y, x-30, y-20)
stick_leg2 = canvas.create_line(x, y, x+30, y-10)
 
canvas.pack()
root.mainloop()
import Tkinter

root = Tkinter.Tk()
root.title('Canvas')
canvas = Tkinter.Canvas(root, width=450, height=450)

canvas.create_oval(100,50,150,100, fill='gray90')

x = 125
y = 175
stick = canvas.create_line(x, y-75, x, y)

diff_x = 25
stick_leg1 = canvas.create_line(x, y, x-diff_x, y+50)
stick_leg2 = canvas.create_line(x, y, x+diff_x, y+50)

y=145
stick_arm1 = canvas.create_line(x, y, x-30, y-20)
stick_leg2 = canvas.create_line(x, y, x+30, y-10)

canvas.pack()
root.mainloop()

But for some reasn (reason) my code doesnt (doesn't) seem to be working

What version of Python are you using? Make sure you are using an integer for the radius.

Python Syntax (Toggle Plain Text)
def draw_circle():
    x = input("please enter the radius of the circle: ")
    print "the radius is", x, type(x)
    centre= Point(100, 100)
    circle1 = Circle(centre, x)
    circle1.draw(win)
def draw_circle():
    x = input("please enter the radius of the circle: ")
    print "the radius is", x, type(x)
    centre= Point(100, 100)
    circle1 = Circle(centre, x)
    circle1.draw(win)

Re: Drawing stick figure?

He is using the graphics file from a python book. Your code for the stick figure would look like this. The Line command uses two points(x,y) for the starting point and (x,y) for the ending point.

Python Syntax (Toggle Plain Text)
def drawStickFigure():
    from graphics import *
    win = GraphWin("Stick figure")
    head = Circle(Point(100, 60), 20).draw(win)
    body = Line(Point(100, 80), Point(100, 120)).draw(win)
    arms= Line(Point(60, 100), Point(140, 100)).draw(win)
    leg1 = Line(Point(100,120), Point(60,160)).draw(win)
    leg2 = Line(Point(100,120), Point(140,160)).draw(win)    
drawStickFigure()
def drawStickFigure():
    from graphics import *
    win = GraphWin("Stick figure")
    head = Circle(Point(100, 60), 20).draw(win)
    body = Line(Point(100, 80), Point(100, 120)).draw(win)
    arms= Line(Point(60, 100), Point(140, 100)).draw(win)
    leg1 = Line(Point(100,120), Point(60,160)).draw(win)
    leg2 = Line(Point(100,120), Point(140,160)).draw(win)    
drawStickFigure()

For the circle you need to use setCoords to make sure that it is in the center of the window.

Python Syntax (Toggle Plain Text)
from graphics import *
def drawCircle():
    win = GraphWin("Stick figure",500,500)
    win.setCoords(-20,-20,20,20)#By setting the coords to this the center is at (0,0)
    x = input("please enter the radius of the circle: ")
    center = Point(0,0)
    circle1 = Circle(center, x)
    circle1.draw(win)
drawCircle()
from graphics import *
def drawCircle():
    win = GraphWin("Stick figure",500,500)
    win.setCoords(-20,-20,20,20)#By setting the coords to this the center is at (0,0)
    x = input("please enter the radius of the circle: ")
    center = Point(0,0)
    circle1 = Circle(center, x)
    circle1.draw(win)
drawCircle()
