That email brings me too a question I've had for awhile now. What is better to 
use pygame.display.flip() or pygame.display.update()?

pygame.display.update() affects only a part of the screen, whereas
pygame.display.flip() updates the whole screen. Therefore, using update()
can increase the perfs of your game.

However, if you update many parts of the screen at the same time (for
instance when you use scrolling, or when you load a full map) it becomes
totally useless. It only makes the screen shine during each update, and it
is pretty annoying to see.

So you have to think about the accurate moment to use update(). I would
suggest calling this function when you update a single surface.

good info, thanks. I'm going to experiment with them both.

[pygame] A little help please

[Silver]

I need some help with a program that I'm trying to write with pygame.

I am having two issues:
* the squares aren't being drawn 1 px small so that they leave a black 
grid
* the squares on the edges are extending, even though I don't think I
told them to.

anyone know how to fix it?
import pygame
import math


squaresize = 64
sqsz = squaresize

width = 799
height = width

radius = .5*sqsz

pygame.init()

screen = pygame.display.set_mode((width,height))

while True:
pygame.event.get()
mousex = pygame.mouse.get_pos()[0]
mousey = pygame.mouse.get_pos()[1]
screen.fill((0,0,0))
for x in xrange(width/squaresize):
for y in xrange(height/squaresize):
hx = x
hy = y
hx *= sqsz
hy *= sqsz
#print hx,hy,sqsz, sqsz
nx = hx+(sqsz/2)-mousex
ny = hy+(sqsz/2)-mousey
nz = ((nx**2)+(ny**2))**.5
if nz == 0:
nz = .001#print nz
n = radius / nz
if n == 0:
n = .001
if n  1:
n = 1

#print n
color = n*255
#print (color,color,color)
#print hx, hy, hx+15, hy+15
pygame.draw.rect(screen, (color,color,color), 
(hx,hy,hx+sqsz-1,hy+sqsz-1))
pygame.display.update()
