PYGLET – Drawing Multiple Sprites
In this article we will see how we can draw multiple spries 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 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 a list of sprites objectsprites = []# position of imagespos_x = 10pos_y = 230for 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-orddinate pos_x = pos_x + 100# on draw event@window.eventdef on_draw(): # clear the window window.clear() # draw the label label.draw() # draw the batch batch.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") # getting mouse button stringvalue = pyglet.window.mouse.buttons_string(2 | 5)# setting image as iconwindow.set_icon(img) # start running the applicationpyglet.app.run() |
