Python游戏开发 unit02_Pygame画基本图形

一、画圆

pygame.draw.circle(surface, color, center, radius)

二、画矩形

#实心矩形
pygame.draw.rect(surface, color, rect)
#空心矩形
pygame.draw.rect(surface, color, rect, width)

三、画线

pygame.draw.line(surface, color, start_pos, end_pos, width)

四、完整演示代码：

import pygame

pygame.init()
pygame.display.set_caption('我的第一个pygame游戏')

WIDTH = 750
HEIGHT = 450
GAP = 50
screen = pygame.display.set_mode((WIDTH, HEIGHT))

#填充背景颜色
screen.fill((255, 255, 255))

#画网格
for i in range(1, int(WIDTH / GAP)):
    pygame.draw.line(screen, (0, 0, 0), (50 * i, 0), (50 * i, HEIGHT), 1)
for j in range(1, int(HEIGHT / GAP)):
    pygame.draw.line(screen, (0, 0, 0), (0, 50 * j), (WIDTH, 50 * j), 1)

#画矩形
pygame.draw.rect(screen, (80, 80, 80), (100, 100, 300, 150))
pygame.draw.rect(screen, (255, 0, 0), (100, 100, 300, 150), 5)
 
#画圆
pygame.draw.circle(screen, (255, 0, 0), (175, 250), 25)
pygame.draw.circle(screen, (255, 0, 0), (325, 250), 25)
 
#更新画布
pygame.display.update()
 
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
