Check collision between a image and a line

by

You missed to create a surface with per pixel alpha by .convert_alpha(), before creating the mask from the “line” Surface:

line_rect = pygame.draw.line(gameDisplay, colors.GREEN, [100, 100], [200, 200], 5)
line_surf = gameDisplay.subsurface(line_rect)
line_mask = pygame.mask.from_surface(line_surf.convert_alpha())

x0, y0 = line_rect.topleft
x1, y1 = player1.rect.topleft

offset = (x0 - x1, y0 - y1)
if player1.mask.overlap(line_mask, offset):
    print("hit : ", count)

See the example: repl.it/@Rabbid76/PyGame-PyGame-SurfaceLineMaskIntersect-1
