1、pygame 画猫

#Author ddz

import pygame, math

def lines():

    pygame.draw.lines(screen, (25,25,25),True,

[(200,100), (300,400), (500,400), (600,100), (700,400), (700,600), (500,800), (300,800), (100,600), (100,400)])

pygame.display.flip()

def circle(x,y):

    pygame.draw.circle(screen, (255,255,0), (x,y),60,0)

pygame.display.flip()

def main():

    while 1:

        for eventin pygame.event.get():

            if event.type== pygame.QUIT:

                exit()

lines()

circle(250,550)

circle(550,550)

arc()

pygame.draw.lines(screen, (25,25,25),True,[(300,750), (500,750)])

pygame.display.flip()

def arc():

    pi = 80

    pygame.draw.arc(screen, (0,20,24), (300,700,200,100), math.pi/1,0)

pygame.display.flip()

if __name__== '__main__':

    pygame.init()

screen= pygame.display.set_mode((800,900))

screen.fill((255,255,255))

pygame.display.flip()

main()

2、pygame 鼠标画线

#Author ddz

import pygame, random

def rand_color():

    return (random.randint(0,255), random.randint(0,255), random.randint(0,255))

def line(start_pos):

    end_pos= (0,0)

i= 1

    while i:

        for eventin pygame.event.get():

            if event.type== pygame.QUIT:

                exit()

elif event.type== pygame.MOUSEBUTTONDOWN:

                print('1鼠标按下:', event.pos)

end_pos= event.pos

i= 0

    pygame.draw.line(screen, rand_color(),start_pos, end_pos)

pygame.display.flip()

def main():

    while 1:

        for eventin pygame.event.get():

            if event.type== pygame.QUIT:

                exit()

elif event.type== pygame.MOUSEBUTTONDOWN:

                line(event.pos)

if __name__== '__main__':

    pygame.init()

screen= pygame.display.set_mode((800,800))

screen.fill((255,255,255))

pygame.display.flip()

main()

3、pygame 鼠标画圆

#Author ddz

import pygame, random,math

def rand_color():

    return (random.randint(0,255), random.randint(0,255), random.randint(0,255))

def circle(center_pos):

    end_pos= (0,0)

i= 1

    while i:

        for eventin pygame.event.get():

            if event.type== pygame.QUIT:

                exit()

elif event.type== pygame.MOUSEBUTTONDOWN:

                #print('1鼠标按下:', event.pos)

                end_pos= event.pos

i= 0

    radius= int(math.sqrt(((center_pos[0]-end_pos[0])**2)+((center_pos[1]-end_pos[1])**2)))

pygame.draw.circle(screen, rand_color(),center_pos, radius,0)

pygame.display.flip()

def main():

    while 1:

        for eventin pygame.event.get():

            if event.type== pygame.QUIT:

                exit()

elif event.type== pygame.MOUSEBUTTONDOWN:

                circle(event.pos)

if __name__== '__main__':

    pygame.init()

screen= pygame.display.set_mode((800,800))

screen.fill((255,255,255))

pygame.display.flip()

main()
