Pygame — Get screen size?
Hey,
First: Hello, i’m new here 😆
And here my question:
It’s a very short question: Is it possible to get the screen size (resolution) with pygame and how do i get it?

import pygame from pygame.locals import * pygame.init() screen = pygame.display.set_mode((640,480), FULLSCREEN) # get the size of the fullscreen display x, y = screen.get_size()There is also a pygame.display.Info() call you can print.

import pygame from pygame.locals import * pygame.init() screen = pygame.display.set_mode((640,480), FULLSCREEN) # get the size of the fullscreen display x, y = screen.get_size()How do you can the size of the window when you change it’s size with the RESIZABLE flag? The size never updates to match the window. How can I get the window size by any other way?

Later on in the app I want to be able to ask that window its width and height so I can decide how to process the mouse position. How do I access the dimensions of that pygame window elsewhere in the program? (event processing loop)

You want to get the surface, then get the size from the surface object.
w, h = pygame.display.get_surface().get_size()
You can get the windows size by first getting the display surface. pygame.display.get_surface(), then calling get_width() / get_height() on the surface.
surface = pygame.display.get_surface() #get the surface of the current active display x,y = size = surface.get_width(), surface.get_height()#create an array of surface.width and surface.height Adding another answer since I haven't seen this one yet.
screen = pygame.display.set_mode() # Default to screen resolution. area = screen.get_rect() We can call get_rect() on screen because it is a surface object. area will be a Rect object, with (0, 0, width, height) information in it.
import pygame as pg def create_window(width, height): """create a width x height resizable window/frame""" win = pg.display.set_mode((width, height), pg.RESIZABLE) # optional fill bg red, default is black win.fill((255, 0, 0)) # optional title info sf = "size x=%s y=%s" % (width, height) pg.display.set_caption(sf) # any extra code here . # draw a white circle white = (255, 255, 255) # center can be fixed or calculated for resize center = (150, 150) radius = 100 pg.draw.circle(win, white, center, radius) pg.display.flip() return win pg.init() width = 300 height = 200 win = create_window(width, height) # event loop and exit conditions (windows titlebar x click) while True: for event in pg.event.get(): if event.type == pg.VIDEORESIZE: width, height = event.size # redraw win in new size win = create_window(width, height) print(win.get_size()) # test if event.type == pg.QUIT: raise SystemExit Unfortunately I'm using the opengl library, so I have discovered that adjusting the size messes up the opengl context somehow. Eventually I'll dig around to figure out how I should cope with that.
