All boxes moving with same speed in same directions and all boxes have same size and colorMake changes step by step to see result
self.dx = randint(1,BOX_SPEED) self.dy = randint(1,BOX_SPEED)and boxes now moving all seperatly at diferent directions.
self.boxes.append( Box( i*2 , i*2 , randint(BOX_MIN_SIZE,BOX_MAX_SIZE) , (i,0,0) )now boxes have diferent sizes
New class boxes handles many boxes. Number of boxes depends on cpnstant MAX_BOXES.
MAX_BOXES = 100and all class Boxes methods is the same only diference is that it handles many boxes.Tutorial Source
Here is Lorenz attractor whery popular attractor i have used basic coloring tehnique.

PovRay source
added constants that helps controlling screen size
SCREEN_X = 500 SCREEN_Y = 500 BOX_SIZE = 20 BOX_SPEED = 1box have speed by axis
self.dx = BOX_SPEED self.dy = BOX_SPEEdetecting if given rect is inside screen borders or not if not then change it direction
def move( self ):
if self.rect.left+BOX_SIZE > SCREEN_X:
self.dx = -BOX_SPEED
if self.rect.left < 0:
self.dx = BOX_SPEED
if self.rect.top+BOX_SIZE > SCREEN_Y:
self.dy = -BOX_SPEED
if self.rect.top < 0:
self.dy = BOX_SPEED
self.rect.left += self.dx
self.rect.top += self.dyafter few line of code where added box move inside given screen and coalide with screen borders There is new object Box. We can draw, mask and move it.Once you init it you can use it with simple interface
box = Box( position_x , position_y , size , (color_red,color_green,color_blue,color_alpha) )moving box to new position. new position calculates x_new = x_old + x
box.move( add_x , add_y )drawes box on the screen
box.draw()draw black box on the screen
box.mask()
Draw some image and make for it
surface image = pygame.image.load("image_name.format")
surface. screen.blit( source_surface , (position_x,position_y) )
Now you can set application window. But there is one problem you have to terminate application by killing.
Adding event handling help us exit from application by clicking close button or pressing some other button.
for event in pygame.event.get():
if event.type == pygame.QUIT:
runing = False
First application and we opening window
screen = pygame.display.set_mode( (width_of_window ,height_of_window ) )
pygame.display.set_mode( (width,height), pygame.FULLSCREEN )
Python Pygame tutorial. This tutorial goal show how to make small and simple pygame pythone script that include all that is need for bigger application. Every tutorial part add only few new lines of code.
Moving Boxes
Goal
Make featured applications with boxes that coaliding one with another.
1. [Set Display]
2. [Event Sytem]
3. [Image loading]
4. [Box object]
5. [Box move]
6. [Boxes move]
7. [Randomnes]
8. [Fullscreen]
I where interested to see how looks visualy distance to the closest point. When I saw result i remembered that it is Voronoi diagramm.

I have found old article about attractors that is resoult what I have done with playing with attractor values. Attractor formula is very simple but result is interesting.
Flower where all list rotating around lists.

This is simple map editor for small games. Also I think it will be useful for other people who started writing game and made first test maps.

Wanted to know how will looks when mousepointer moving and all arrows shows it direction

You can shut your bullets and they will contact with difrent boxes with diffrent result there is boxes that speed up, freeze, slow down bullets.

I wanted to know how many simple object can be drawn by Pygame. Red point is starting point for flying bullets. And only thing with bullets have coalision is screen border. You can shut new bullets with mouse.

After some optimisations script works faster.

Also I have implemented the same on C++.

Python scripth with generating picture of points from bmp image. Colors in bmp image is like koeficent map with allow generate more random points in any place of image you want. There shown source image from what where generated points on black image.
