Pygame - Drawing Shapes

使用 pygame.draw 模块中的函数可以在游戏窗口上绘制矩形、圆形、椭圆形、多边形和线条等不同形状——

Different shapes such as rectangle, circle, ellipse, polygon and line can be drawn on the game window by using functions in pygame.draw module −

draw a rectangle

rect(surface, color, rect)

draw a polygon

polygon(surface, color, points)

draw a circle

circle(surface, color, center, radius)

draw an ellipse

ellipse(surface, color, rect)

draw an elliptical arc

arc(surface, color, rect, start_angle, stop_angle)

draw a straight line

line(surface, color, start_pos, end_pos, width)

Example

以下示例使用这些函数绘制不同的形状——

Following example uses these functions to draw different shapes −

import pygame

pygame.init()
screen = pygame.display.set_mode((400, 300))
done = False
red = (255,0,0)
green = (0,255,0)
blue = (0,0,255)
white = (255,255,255)
while not done:
   for event in pygame.event.get():
      if event.type == pygame.QUIT:
         done = True
   pygame.draw.rect(screen, red, pygame.Rect(100, 30, 60, 60))
   pygame.draw.polygon(screen, blue, ((25,75),(76,125),(275,200),(350,25),(60,280)))
   pygame.draw.circle(screen, white, (180,180), 60)
   pygame.draw.line(screen, red, (10,200), (300,10), 4)
   pygame.draw.ellipse(screen, green, (250, 200, 130, 80))
   pygame.display.update()

Output

different shapes

如果函数中添加了一个可选的整型参数，形状将以指定的颜色作为轮廓颜色进行绘制。数字对应于轮廓的粗细和形状内部的背景颜色。

If an optional integer parameter is added to the functions, the shape will be drawn with specified color as outline color. Number corresponds to thickness of the outline and background color inside the shape.

pygame.draw.rect(screen, red, pygame.Rect(100, 30, 60, 60),1)
pygame.draw.circle(screen, white, (180,180), 60,2)
pygame.draw.ellipse(screen, green, (250, 200, 130, 80),5)

Output

different shape
