hi,
either I made a mistake or it doesn't work with Screen as a Surface
I made:

screen=pygame.display.set_mode(SCREEN_SIZE,pygame.SRCALPHA,32)
pygame.draw.circle(screen,(200,200,255,0.4)
(self.blit_pos[0],self.blit_pos[1]),int(gdata.cans[self.akt][1]))

the gdata is gamespecific, it meens the radius.

Here the circle is drawn solid.
