PYGLET – Accessing Batch of Sprite
In this article we will see how we can access the batch object of 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. The sprite can be migrated from one batch to another, or removed from its batch (for individual drawing). Note that this can be an expensive operation.
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 batch attribute with sprite object
Syntax : sprite.batch
Argument : It takes no argument
Return : It returns batch object
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 = "w3wiki" # creating a window window = pyglet.window.Window(width, height, title) # text text = "Welcome to w3wiki" # 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 w3wiki 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" ) # setting image as icon window.set_icon(img) # getting batch of the first sprite sprite = sprites[ 0 ] value = sprite.batch # setting this value to the label label.text = str (value) # start running the application pyglet.app.run() |
