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
# 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 proeprties # 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 = 10pos_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-orddinate 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: # printng 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() |
