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 = "Geeksforneveropen" # creating a window window = pyglet.window.Window(width, height, title) # text text = "Welcome to neveropen" # 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 neveropen 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() |
Output :
