PYGLET – Drawing Multiple Sprites

In this article, we will see how we can draw multiple sprites on the window 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.
Sprites can be batched together and drawn at once more quickly than if each of their draw methods were called individually. The following example creates one hundred ball sprites and adds each of them to a Batch. The entire batch of sprites is then drawn in one call

We can create a window, batch and sprite with the help of commands given below 

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

# creating a batch 
batch = pyglet.graphics.Batch()

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

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 = "Geeksforgeeks"

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

# text
text = "Welcome to GeeksforGeeks"

# 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 geeksforgeeks image
image = pyglet.image.load('gfg.png')

# creating a list of sprites object
sprites = []

# position of images
pos_x = 10
pos_y = 230

for i in range(5):

    # temporary sprite object
    temp = pyglet.sprite.Sprite(image, pos_x, pos_y, batch = batch)

    # append the sprite object to the list
    sprites.append(temp)

    # increment the x co-ordinate
    pos_x = pos_x + 100


# on draw event
@window.event
def on_draw():

    # clear the window
    window.clear()

    # draw the label
    label.draw()

    # draw the batch
    batch.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")



# getting mouse button string
value = pyglet.window.mouse.buttons_string(2 | 5)


# setting image as icon
window.set_icon(img)

# start running the application
pyglet.app.run()

Output :
