Building a car using the Graphics111 library
- Get a copy of the graphics111.py library
- Save it in your main directory (where you keep you python programs) and save it as graphics111.py
- Create a car using the new classes now available in the graphics111 library. Call it lab12.py.
from graphics111 import * MAXWIDTH = 600 MAXHEIGHT = 400 class Car: def __init__(self, x, y, w, h, color ): self._body = Rectangle( x, y, w, h, color ) self._w1 = Wheel( x+w//4, y+h, w//4 ) self._w2 = Wheel( x+3*w//4, y+h, w//4 ) def draw( self, canvas ): self._body.draw( canvas ) self._w1.draw( canvas ) self._w2.draw( canvas ) def main(): win = GraphicsWindow(MAXWIDTH, MAXHEIGHT) canvas = win.canvas() p1 = Car( 100, 100, 50, 20, (250, 250, 0) ) p1.draw( canvas ) win.wait() win.close() main()
- Notice how short the program is now that the classes for the wheels and rectangles are in the graphics111 library!
Adding A Menu
- Add a menu at the top left of the window. Don't try to activate it, it won't respond yet...
from graphics111 import *
MAXWIDTH = 600
MAXHEIGHT = 400
class Car:
def __init__(self, x, y, w, h, color ):
self._body = Rectangle( x, y, w, h, color )
self._w1 = Wheel( x+w//4, y+h, w//4 )
self._w2 = Wheel( x+3*w//4, y+h, w//4 )
def draw( self, canvas ):
self._body.draw( canvas )
self._w1.draw( canvas )
self._w2.draw( canvas )
def main():
global menu
win = GraphicsWindow(MAXWIDTH, MAXHEIGHT)
canvas = win.canvas()
menu = Menu()
menu.draw( canvas )
p1 = Car( 100, 100, 50, 20, (250, 250, 0) )
p1.draw( canvas )
win.wait()
win.close()
main()
