python笔记 （三十九）pygame（6） 绘制简单图形

一.矩形

import pygame
import sys

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)

size = width, height = 640, 200
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.rect(screen, BLACK, (50, 50, 150, 50), 0)
    pygame.draw.rect(screen, BLACK, (250, 50, 150, 50), 1)
    pygame.draw.rect(screen, BLACK, (450, 50, 150, 50), 10)

    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.rect(screen, BLACK, (50, 50, 150, 50), 0)
总共四个参数，第三个参数是左上角坐标，宽度，深度
第四个是边框宽度，如果是0，就全部填充

二.多边形

import pygame
import sys

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)

POINTS = [(200, 75), (300, 25),(400, 75),(450, 25),(450, 125), (400, 75),(300,125)]

size = width, height = 640, 200
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.polygon(screen, BLACK, POINTS, 0)

    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.polygon(screen, BLACK, POINTS, 0)
第三个参数是各个顶点的坐标
第四个依旧是边框宽度，0的时候填充

三.圆形

import pygame
import sys

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,0,255)
RED = (255,0,0)

size = width, height = 640, 500
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")

position = size[0]//2,size[1]//2

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.circle(screen, BLACK, position, 25, 0)
    pygame.draw.circle(screen, BLUE, position, 75, 1)
    pygame.draw.circle(screen, RED, position, 125, 1)

    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.circle(screen, BLACK, position, 25, 0)
第三个参数是圆心
第四个是半径
第四个依旧是边框宽度，0的时候填充

四.椭圆

import pygame
import sys

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,0,255)
RED = (255,0,0)

size = width, height = 640, 500
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")


clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.ellipse(screen, BLACK, (100, 100, 440, 100), 1)
    pygame.draw.ellipse(screen, BLACK, (220, 50, 200, 200), 0)
    
    
    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.ellipse(screen, BLACK, (100, 100, 440, 100), 1)
第三个参数就是矩形的左上角，宽度和深度
第四个是边框宽度，0填充

五.弧线

import pygame
import sys
import math

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,0,255)
RED = (255,0,0)

size = width, height = 640, 500
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")


clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.arc(screen, BLACK, (100, 100, 440, 100),0, math.pi, 1)
    pygame.draw.arc(screen, BLACK, (220, 50, 200, 200), math.pi, math.pi * 2, 1)
    
    
    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.arc(screen, BLACK, (100, 100, 440, 100),0, math.pi, 1)
第三个还是矩形的边界数据
第四个和第五个是指开始的角度和结束的角度
最后一个是边框宽度，但是0的时候不会填充

六.线段

import pygame
import sys
import math

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,0,255)
RED = (255,0,0)

size = width, height = 640, 500
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")

POINTS = [(200, 75), (300, 25),(400, 75),(450, 25),(450, 125), (400, 75),(300,125)]

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.lines(screen, BLACK, 0, POINTS, 1)
    
    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.lines(screen, BLACK, 0, POINTS, 1)第三个是是否要闭合，0是不闭合，1是闭合


但是最后一个参数为0时不能填充

aa是抗锯齿

import pygame
import sys
import math

pygame.init()

WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,0,255)
RED = (255,0,0)

size = width, height = 640, 500
screen = pygame.display.set_mode(size)
pygame.display.set_caption("图形")

POINTS = [(200, 75), (300, 25),(400, 75),(450, 25),(450, 125), (400, 75),(300,125)]

clock = pygame.time.Clock()

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    screen.fill(WHITE)

    pygame.draw.line(screen, BLACK, (100, 200),(540, 250), 1)
    pygame.draw.aaline(screen, BLACK, (100, 250),(540,300), 1)
    pygame.draw.aaline(screen, BLACK, (100, 300),(540,350), 0)
    
    pygame.display.flip()

    clock.tick(10)

函数pygame.draw.aaline(screen, BLACK, (100, 250),(540,300), 1)
最后一个参数是是否开启抗锯齿
1是开启，0是不开启
