画一个圆形

FFFFFF是白色，000000是黑色

import pygame

pygame.init()
windowSize=[400,300]
screen=pygame.display.set_mode(windowSize)
pygame.display.set_caption("CircleGame")

colour=pygame.color.Color("#FFFFFF")
done=False

while not done:
    pygame.draw.circle(screen,colour,[200,150],50)
    pygame.display.flip()
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            done=True
pygame.quit()

画矩形

import pygame

pygame.init()
windowSize=[400,300]
screen=pygame.display.set_mode(windowSize)
pygame.display.set_caption("RectGame")

colour=pygame.color.Color("#0A32F4")
done=False

while not done:
    pygame.draw.rect(screen,colour,[10,20,30,40])
    pygame.display.flip()
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            done=True
pygame.quit()

长方形彩虹

import pygame
pygame.init()

width=400
height=300
windowSize=[width,height]
screen=pygame.display.set_mode(windowSize)
colour=pygame.color.Color(‘#646400‘)
row=0
done=False
while not done:
    increment=255/100
    while row<=height:
        pygame.draw.rect(screen,colour,(0,row,width,row+increment))
        pygame.display.flip()
        if colour[2]+increment<255:
            colour[2]+=increment
        row+=increment
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            done=True

pygame.quit()

颜色栅栏

import random
import pygame
pygame.init()

width=400
height=300
windowSize=[width,height]
screen=pygame.display.set_mode(windowSize)
clock=pygame.time.Clock()
sqrW=width/10
sqrH=height/10

done=False
while not done:
    red=random.randrange(0,256)
    green=random.randrange(0,256)
    blue=random.randrange(0,256)
    x=random.randrange(0,width,sqrW)
    y=random.randrange(0,height,sqrH)
    pygame.draw.rect(screen,(red,green,blue),(x,y,sqrW,sqrH))

    pygame.display.flip()
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            done=True

    clock.tick(10)
pygame.quit()

tick函数控制循环的速度，它确定循环每秒重复的次数

创建椭圆

import math
import pygame
pygame.init()

windowSize=[400,300]
screen=pygame.display.set_mode(windowSize)
clock=pygame.time.Clock()

width=200
height=200

x=windowSize[0]/2-width/2
y=windowSize[1]/2-height/2

colour=pygame.color.Color(‘#57B0F6‘)
black=pygame.color.Color(‘#000000‘)

count=0
done=False

while not done:
    screen.fill(black)
    pygame.draw.ellipse(screen,colour,[x,y,width,height])
    width+=math.cos(count)*10
    x-=(math.cos(count)*10)/2
    height+=(math.sin(count)*10)/2
    count+=0.5

    pygame.display.flip()

    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            done=True

    clock.tick(1000)
pygame.quit()
