python中的pygame小练习（2）基本图形绘制

基本图形绘制

绘制矩形

pygame.draw.rect(screen,BLACK,(50, 50, 150, 50), 0) #Surface ：矩形绘制在哪个Surface对象上 # color：边框颜色 # Rect：指定矩形范围,就是四个左边点的位置 # width: 指定边框大小，0表示填充这个矩形，1表示边框一个像素

绘制多边形 polygon(Surface, color, pointlist, width=0) #Surface ：矩形绘制在哪个Surface对象上 # color：边框颜色 # Rect：指定矩形范围,就是顶点的位置 # width: 指定边框大小，0表示填充这个矩形，1表示边框一个像素 例：

import pygame import sys from pygame.locals import * pygame.init() GREEN = (0, 255, 0) points = [(200, 75), (300, 25), (400, 75), (450, 25), (450, 125), (400, 75), (300, 125)] size = width, height = 640, 480 screen = pygame.display.set_mode(size) pygame.display.set_caption("FIshC Demo") clock = pygame.time.Clock() while True: for event in pygame.event.get(): if event.type == QUIT: sys.exit() screen.fill(WHITE) pygame.draw.polygon(screen, GREEN,points, 0) #把内存中的画面翻转到屏幕上 pygame.display.flip() #帧率 一秒10帧 clock.tick(10)

结果：

circle（Surface, color, pos, radius, width=0）

pos:圆心的位置 radius：半径的大小

import pygame import sys from pygame.locals import * pygame.init() GREEN = (0, 255, 0) RED = (255, 0, 0) BLUE = (0, 0, 255) size = width, height = 640, 480 screen = pygame.display.set_mode(size) pygame.display.set_caption("FIshC Demo") position = size[0]//2, size[1]//2 #两个除号表示整除 clock = pygame.time.Clock() moving = False while True: for event in pygame.event.get(): if event.type == QUIT: sys.exit() if event.type == MOUSEBUTTONDOWN: if event.button == 1: #1鼠标左键2鼠标滚轮3鼠标右键4滚轮向上5滚轮向下 moving = True if event.type == MOUSEBUTTONUP: if event.button == 1: moving = False if moving: position = pygame.mouse.get_pos() #获得鼠标当前位置 screen.fill(WHITE) pygame.draw.circle(screen, RED,position, 25, 1) pygame.draw.circle(screen, BLUE, position, 75, 1) pygame.draw.circle(screen, GREEN, position, 125, 1) #把内存中的画面翻转到屏幕上 pygame.display.flip() #帧率 一秒10帧 clock.tick(10)

结果：鼠标点击会随鼠标移动 绘制椭圆 ellipse(Surface, color, Rect, width=0) Rect是一个矩形，如果椭圆限制在一个长方形内就是椭圆，如果限制在一个正方形内，就是正圆。

import pygame import sys from pygame.locals import * pygame.init() WHITE = (255, 255, 255) BLACK = (0, 0, 0) GREEN = (0, 255, 0) RED = (255, 0, 0) BLUE = (0, 0, 255) size = width, height = 640, 480 screen = pygame.display.set_mode(size) pygame.display.set_caption("FIshC Demo") clock = pygame.time.Clock() moving = False while True: for event in pygame.event.get(): if event.type == QUIT: sys.exit() screen.fill(WHITE) pygame.draw.ellipse(screen, BLACK, (100, 100, 400, 100) , 1) pygame.draw.ellipse(screen, BLACK, (200, 50, 200, 200), 1) pygame.display.flip() #帧率 一秒10帧 clock.tick(10)

绘制弧线 act(Surface, color,Rect, start_angle, stop_angle, width=1) start_angle:表示从椭圆的哪一部分角度开始 stop_angle:表示从椭圆的哪一部分角度结束

例：画了个死鱼眼

import pygame import sys import math from pygame.locals import * pygame.init() WHITE = (255, 255, 255) BLACK = (0, 0, 0) GREEN = (0, 255, 0) RED = (255, 0, 0) BLUE = (0, 0, 255) size = width, height = 640, 480 screen = pygame.display.set_mode(size) pygame.display.set_caption("FIshC Demo") clock = pygame.time.Clock() moving = False while True: for event in pygame.event.get(): if event.type == QUIT: sys.exit() screen.fill(WHITE) pygame.draw.arc(screen, BLACK, (100, 100, 400, 100) , 0, math.pi, 1) pygame.draw.arc(screen, BLACK, (200, 50, 200, 200),math.pi, math.pi * 2, 1) pygame.draw.arc(screen, BLACK, (100, 200, 400, 100), math.pi, math.pi * 2, 1) pygame.display.flip() #帧率 一秒10帧 clock.tick(10)

画线段，一条线和多条线

line(Surface, color, start_pos, end_pos, width=1)

lines(Surface, color, closed, pointlist, width=1）
