PYGLET – Updating Sprite - GeeksforGeeks

19 Sep, 2021
In this article we will see how we can update 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. Updating means to changing the properties of sprite, properties can be size, position etc.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 update method with sprite objectSyntax : sprite.update(x=None, y=None, rotation=None, scale=None, scale_x=None, scale_y=None)Argument : It takes optional argument i.e x, y co-ordinates (int), rotation (float), scale (float), horizontal scale (float), vertical scale (float)Return : It returns None  
Below is the implementation  
Python3
# importing pyglet moduleimport pygletimport pyglet.window.key as key   # width of windowwidth = 500   # height of windowheight = 500   # caption i.e title of the windowtitle = "Geeksforgeeks"   # creating a windowwindow = pyglet.window.Window(width, height, title)   # text text = "Welcome to GeeksforGeeks"  # creating label with following properties# font = cooper# position = 250, 150# anchor position = centerlabel = pyglet.text.Label(text,                          font_name ='Cooper',                          font_size = 16,                          x = 250,                           y = 150,                          anchor_x ='center',                           anchor_y ='center')  # creating a batchbatch = pyglet.graphics.Batch() # loading geeksforgeeks imageimage = pyglet.image.load('gfg.png')   # creating sprite object# it is instance of an image displayed on-screensprite = pyglet.sprite.Sprite(image, x = 200, y = 230)   # on draw event@window.eventdef on_draw():           # clear the window    window.clear()           # draw the label    label.draw()         # draw the image on screen    sprite.draw()       # key press event    @window.eventdef on_key_press(symbol, modifier):       # key "C" get press    if symbol == key.C:                 # printing the message        print("Key : C is pressed")         # image for iconimg = image = pyglet.resource.image("gfg.png") # setting image as iconwindow.set_icon(img) # updating the sprite# x, y = 10, 300# rotation = 45# scale = 2sprite.update(100, 300, 45, 2)      # start running the applicationpyglet.app.run()
