PYGLET – Shape Rotation
  • Last Updated : 23 Sep, 2020

In this article we will see how we can access the rotation of the shape in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material type. Many shapes are drawn with the help of shapes module of pyglet. A rotation is a circular movement of an object around a center of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axes. If the axis passes through the body’s center of mass, the body is said to rotate upon itself, or spin.

We can create a window with the help of command given below

# creating a window
window = pyglet.window.Window(width, height, title)

In order to create window we use rotation attribute with the shape

Syntax : shape.rotation

Argument : It takes no argument



Return : It returns int or float

Note : Shape like circle don’t have rotation property

Below is the implementation




# importing pyglet module 
import pyglet
  
# importing shapes from the pyglet
from pyglet import shapes
  
# width of window 
width = 500
    
# height of window 
height = 500
    
# caption i.e title of the window 
title = "Geeksforgeeks"
    
# creating a window 
window = pyglet.window.Window(width, height, title) 
  
# creating a batch obect
batch = pyglet.graphics.Batch()
  
  
# properties of rectangle
# co-ordinates of rectangle
co_x = 150
co_y = 150
  
# width of rectangle
width = 250
  
# height of rectangle
height = 150
  
# color = green
color = (50, 225, 30)
  
# creating a rectangle
rec = shapes.Rectangle(co_x, co_y, width, height, color = color, batch = batch)
  
# changing opacity of the rect1
# opacity is visibility (0 = invisible, 255 means visible)
rec.opacity = 180
  
  
# creating another rectangle with properties
# x, y co ordinate : 50, 250
# width, height of rectangle : 300, 200
# color = red
color = (255, 25, 25)
  
# properties of circle
# co-ordinates of circle
circle_x = 200
circle_y = 300
  
# size of circle
# color = green
size_circle = 100
  
# creating a circle 
circle = shapes.Circle(circle_x, circle_y, size_circle, color =(250, 22, 30), batch = batch)
  
# changing opacity of the circle1
# opacity is visibility (0 = invisible, 255 means visible)
circle.opacity = 170
  
  
# window draw event
@window.event
def on_draw():
      
    # clear the window
    window.clear()
      
    # draw the batch
    batch.draw()
      
      
# rotating the rectangle
rec.rotation = 45
      
  
  
# run the pyglet application
pyglet.app.run()
