[英]Pygame rectangles not drawing
So I'm not exactly new to python, but I am new to pygame.所以我对python并不完全陌生,但我是pygame的新手。 I've written a basic script that should build a grid of thin rectangles of random shades of grey.
我已经编写了一个基本脚本,它应该构建一个由随机灰色阴影的细矩形组成的网格。 as far as I can tell it's building the objects properly and all the relevant variables seem to be working.
据我所知,它正在正确构建对象,并且所有相关变量似乎都在工作。 but pygame will not draw the rectangles.
但 pygame 不会绘制矩形。 I'm sure its something fairly simple, can someone point out my mistake?
我确定它相当简单,有人可以指出我的错误吗?
just to clarify, the prints were for testing purposes只是为了澄清,印刷品用于测试目的
#simple pygame grid drawer
import pygame as pg
import random as r
pg.init()
X = 600
Y = 600
surface_screen = pg.display.set_mode((X , Y))
colors = [(i , i , i) for i in range(255)]
class line:
def __init__(self , x , y , hight , width):
self.x = x
self.y = y
self.color = r.choice(colors)
self.hight = hight
self.width = width
lines = []
lines.append([line(x*50 , Y , Y , 15) for x in range(X // 50)])
lines.append([line(X , y*50 , 15 , X) for y in range(Y // 50)])
print("yep1")
for A in lines:
for i in A:
pg.draw.rect(surface_screen , i.color , pg.Rect(i.x , i.y , i.hight , i.width))
print(f"yep2 {i.color} , X:{i.x} , Y:{i.y} , hight:{i.hight} , width:{i.width}")
done = False
while not done:
for event in pg.event.get():
if event.type == pg.QUIT:
done = True
pg.display.flip()
pg.quit()
The rectangles are out of bounds, because either the x
or the y
coordinate of the rectangle is 600.矩形超出边界,因为矩形的
x
或y
坐标是 600。
Change the following lines of code:更改以下代码行:
lines.append([line(x*50 , Y , Y , 15) for x in range(X // 50)])
lines.append([line(x*50, 0, 15, Y) for x in range(X // 50)])
lines.append([line(X , y*50 , 15 , X) for y in range(Y // 50)])
lines.append([line(0, y*50, Y, 15) for y in range(Y // 50)])
