In this article we will see how we can draw circles on 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 circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. Circle is drawn with the help of shapes module in pyglet.
We can create a window with the help of command given below
# creating a window window = pyglet.window.Window(width, height, title)
In order to create window we use Circle method with pyglet.shapes
Syntax : shapes.Circle(x, y, size, color)
Argument : It takes first two integer i.e circle position, third integer as size of circle and fourth is tuple i.e color of circle as argument
Return : It returns Circle object
Below is the implementation
Python3
# importing pyglet module import pyglet# importing shapes from the pygletfrom pyglet import shapes# width of window width = 500 # height of window height = 500 # caption i.e title of the window title = "GeeksforLazyroar" # creating a window window = pyglet.window.Window(width, height, title) # creating a batch objectbatch = pyglet.graphics.Batch()# properties of circle# co-ordinates of circlecircle_x = 250circle_y = 250# size of circle# color = greensize_circle = 100# creating a circle circle1 = shapes.Circle(circle_x, circle_y, size_circle, color =(50, 225, 30), batch = batch)# changing opacity of the circle1# opacity is visibility (0 = invisible, 255 means visible)circle1.opacity = 250# creating another circle with other properties# new position = circle1_position - 50# new size = previous radius -20# new color = redcircle2 = shapes.Circle(circle_x-50, circle_y-50, size_circle-20, color =(250, 25, 30), batch = batch)# changing opacity of the circle2circle2.opacity = 150# window draw event@window.eventdef on_draw(): # clear the window window.clear() # draw the batch batch.draw()# run the pyglet applicationpyglet.app.run() |
