PYGLET – Sprite Vertical Scale

0 0 2 minutes read

In this article we will see how we can access vertical scale of the sprite 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 sprite is an instance of an image displayed on-screen. Multiple sprites can display the same image at different positions on the screen. Sprites can also be scaled larger or smaller, rotated at any angle and drawn at a fractional opacity. Image is loaded with the help of image module of pyglet. Sprite vertical scale is vertical scaling factor. A scaling factor of 1 (the default) has no effect. A scale of 2 will draw the sprite at twice the native height of its image.
We can create a window and sprite object with the help of commands given below

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

# creating a sprite object
sprite = pyglet.sprite.Sprite(img, x, y)

In order to create window we use scale_y attribute with sprite object
Syntax : sprite.scale_y
Argument : It takes no argument
Return : It returns float value

Below is the implementation

Python3

# importing pyglet module 
import pyglet 
import pyglet.window.key as key
   
# width of window 
width = 500
   
# height of window 
height = 500
   
# caption i.e title of the window 
title = "Geeksforzambiatek"
   
# creating a window 
window = pyglet.window.Window(width, height, title) 
   
# text  
text = "Welcome to zambiatek"
  
# creating label with following properties
# font = cooper
# position = 250, 150
# anchor position = center
label = pyglet.text.Label(text, 
                          font_name ='Cooper', 
                          font_size = 16, 
                          x = 250,  
                          y = 150, 
                          anchor_x ='center',  
                          anchor_y ='center')
 
 
# creating a batch 
batch = pyglet.graphics.Batch()
 
# loading zambiatek image
image = pyglet.image.load('gfg.png')
 
 
 
# creating sprite object
# it is instance of an image displayed on-screen
sprite = pyglet.sprite.Sprite(image, x = 200, y = 230)
   
# on draw event 
@window.event 
def on_draw(): 
       
    # clear the window 
    window.clear() 
       
    # draw the label
    label.draw() 
     
    # draw the image on screen
    sprite.draw()
       
# key press event     
@window.event 
def on_key_press(symbol, modifier): 
   
    # key "C" get press 
    if symbol == key.C: 
         
        # printing the message
        print("Key : C is pressed")
         
# image for icon 
img = image = pyglet.resource.image("gfg.png") 
 
# setting image as icon 
window.set_icon(img) 
 
# accessing vertical scale of the sprite
value = sprite.scale_y = 3
 
# creating text from sprite
text = "Vertical Scale : " + str(value)
 
# setting text to the label
label.text = text
    
# start running the application 
pyglet.app.run()
