I assume your game has a main loop, and all your sprites are in a list called sprites. In your main loop, get all events, and check for the MOUSEBUTTONDOWN or MOUSEBUTTONUP event. while … # your main loop # get all events ev = pygame.event.get() # proceed events for event in ev: # handle … Read more
I was considering both Pygame and Pyglet for a small 2D shooter, and after looking at source code and some tutorials went with Pyglet. I was very happy with the results. Pyglet worked immediately and was enjoyable to work with, and conceptually very clean. It certainly had a Pythonic feel to me: you could get … Read more
That function expects decimal for s (saturation) and v (value), not percent. Divide by 100. >>> import colorsys # Using percent, incorrect >>> test_color = colorsys.hsv_to_rgb(359,100,100) >>> test_color (100, -9900.0, -9900.0) # Using decimal, correct >>> test_color = colorsys.hsv_to_rgb(1,1,1) >>> test_color (1, 0.0, 0.0) If you would like the non-normalized RGB tuple, here is a … Read more
Short answer: When you use pygame.transform.rotate the size of the new rotated image is increased compared to the size of the original image. You must make sure that the rotated image is placed so that its center remains in the center of the non-rotated image. To do this, get the rectangle of the original image … Read more
The main difference between pygame.display.flip and pygame.display.update is, that display.flip() will update the contents of the entire display display.update() allows to update a portion of the screen, instead of the entire area of the screen. Passing no arguments, updates the entire display To tell PyGame which portions of the screen it should update (i.e. draw … Read more
You can scale the image with pygame.transform.scale: import pygame picture = pygame.image.load(filename) picture = pygame.transform.scale(picture, (1280, 720)) You can then get the bounding rectangle of picture with rect = picture.get_rect() and move the picture with rect = rect.move((x, y)) screen.blit(picture, rect) where screen was set with something like screen = pygame.display.set_mode((1600, 900)) To allow your … Read more
You need to apply an offset to the position of your entities when drawing them. Let’s call that offset a camera, since this is the effect we want to achieve with this. First of all, we can’t use the draw function of the sprite group, since the sprites don’t need to know that their position … Read more
Just for completeness, here’s a nice solution from Dave Smith’s blog: from contextlib import contextmanager import sys, os @contextmanager def suppress_stdout(): with open(os.devnull, “w”) as devnull: old_stdout = sys.stdout sys.stdout = devnull try: yield finally: sys.stdout = old_stdout With this, you can use context management wherever you want to suppress output: print(“Now you see it”) … Read more

pygame.draw functions will not draw with alpha. The documentation says: Most of the arguments accept a color argument that is an RGB triplet. These can also accept an RGBA quadruplet. The alpha value will be written directly into the Surface if it contains pixel alphas, but the draw function will not draw transparently. What you … Read more
