Draw a transparent rectangle in pygame

Question

How can I draw a rectangle that has a color with an alpha? I have:

windowSurface = pygame.display.set_mode((1000, 750), pygame.DOUBLEBUF)
pygame.draw.rect(w         


        

Answer 1

You can add a fourth value to your color tuple to represent Alpha:

pygame.draw.rect(windowSurface, (255, 255, 255, 127), pygame.Rect(0, 0, 1000, 750))
