PyGame : Fix error install pygame module on python 3.4.

Today I started to install pygame with python 3.4.1.
I got a lot of errors first with pip tool, see all errors.

PyGame : How play ogg file.

Let's see how to play file.ogg file with pygame python module.

import pygame
import time
pygame.init()
pygame.mixer.music.load('file.ogg')
pygame.mixer.music.play()
time.sleep(1.5)

PyGame : Effects - part 003.

This is a part 003 from pygame tutorial series and is a little more advanced for you.
The reason comes with get_palette and set_palette functions and gif image with 8 bits.
Of course, I could use pygame.PixelArray but is not the purpose of this tutorial.
The python script comes with one surface screen, one surface for image and also one surface of a blur.
I set the resolution to be sized at 640,480. I have motion vectors for two directions and with this I make a circle follow path from sin and cos.
The path come from x and y variables ( width and height).
With angle_xd and angle_yd I increment the angles.
This is the result:
This is the source code:

import pygame, pygame.transform, pygame.image
from pygame.surfarray import *
from pygame.locals import *
from numpy import *
resolution  = array((640,480))
PI  = 3.14159
DEG2RAD = PI/180
print resolution[0], resolution[1]

def main():
    
    pygame.init()

    screen = pygame.display.set_mode(resolution,0,8)
    sprite = pygame.image.load("test_random.gif")
    sprite.set_palette(sprite.get_palette())
    sprite.set_colorkey((255,255,255))
    screen.set_palette(sprite.get_palette())
    area_work = pygame.Surface(resolution,0,8)
    area_work.set_palette(sprite.get_palette())

    angle_xd = 0
    angle_yd = 0
    
    while 1:

        for e in pygame.event.get():
            if e.type in (QUIT,KEYDOWN,MOUSEBUTTONDOWN):
                return
        x    = ((resolution[0])/5)*cos((angle_xd*DEG2RAD))+((resolution[0])/2-128)
        print x
        y    = ((resolution[1])/5)*sin((angle_yd*DEG2RAD))+((resolution[1])/2-128)
        angle_xd  += 1
        angle_yd  += 1
        area_work = pygame.transform.scale(screen, (resolution[0]+8,resolution[1]+8))
        tmp = pygame.surfarray.array2d(area_work)
        blur = array(tmp)
        blur[1:,:]  += tmp[:-1,:]*32
        blur[:-1,:] += tmp[1:,:]*32
        blur[:,1:]  += tmp[:,:-1]*32
        blur[:,:-1] += tmp[:,1:]*32
        blur /= 31
        blit_array(screen, blur[8:resolution[0]+32,8:resolution[1]+32])
        screen.blit(sprite,(x,y))
 pygame.display.update()

if __name__ == '__main__': main()

PyGame : Effects - part 002.

This is another tutorial about pygame and python 2.7 is very simple.
I make this tutorial for educational purposes for the children versus python language.
I used for most common variables the Romanian language and this will allow you to understand well the variables versus python language script.
I used this version of python:

C:\Python27>python.exe
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

This python script comes with few functions:

Imagine_hasurata - fill the image 

ImaginePicatura - draw drop

Pregatire - setup drawing

I let rect variable for python pygame sprite.py ( need to be set the name to rect from rectangle).
Also, I have two python class to make the drop and trail drop into the screen.

This is the effect result:

This is the python script:

PyGame : Effects - part 001.

Today I come one simple and nice tutorial about pygame python module over python version 3.4.
The python script just makes two effects.
First is one fade effect from transparent to black. I also added one green color.
Another effect come with the dizzy star base math python module and random python module.
Because this combined colors green and blue are funny I make star blue.
The script is simple :

• created variables;
• make pygame windows; 
• make fade background function;
• make one class for shape ( and this can be updated );
• make loop the game and escape key option;
•  ... and finally, add shape class and variable into loop pygame script.

Let's see the script:

# Cătălin George Feștilă 
# http://free-tutorials.org

import pygame
import random
import math
from pygame.locals import *

#initialize pygame and random seed
pygame.init()
random.seed()

#transparent to black for fade effect
def background_fade():
    rec = pygame.Surface(screensize)
    if frame != 0:
        rec.set_alpha(10)
        rec.fill((0,0,0))
    else:
        rec.set_alpha(255)
        rec.fill(draw_color)
    screen.blit(rec,(0,0))
    del rec

#all mathmatical shapes
class shape():
    xy = [0,0]   #location
    rot = [0.0,0.0] #rotation
    color = '.'   #color/shape value
    dim_size = 1
 #constructor
    def __init__(self,xy,dim_size,color):
        self.xy = xy
        self.dim_size = dim_size
        
        self.rot = [(random.random()*(math.pi)),.002]
        self.color = color
 
 #define shape
    def set_shape(self,color):
        self.color = color
    
 #draw shape    
    def draw(self):
        #rotation
        self.rot[0] += self.rot[1]
        if self.rot[0] > math.pi*2:
            self.rot[0] -= math.pi*2
        #blue/star
        if self.color == 'blue':
            for x in range(5):
                pygame.draw.aaline(screen,(0,0,255),\
                        (((math.cos(self.rot[0]+(x*((math.pi*2)/5)))*self.dim_size)+self.xy[0]),\
                        ((math.sin(self.rot[0]+(x*((math.pi*2)/5)))*self.dim_size)+self.xy[1])),\
                        (((math.cos(self.rot[0]+((x+2)*((math.pi*2)/5)))*self.dim_size)+self.xy[0]),\
                        ((math.sin(self.rot[0]+((x+2)*((math.pi*2)/5)))*self.dim_size)+self.xy[1])),\
                        1)

#start main pygame effect
while 1:
    #create variable for pygame
    screensize = (640,480)
    screen = pygame.display.set_mode(screensize, 0, 32)
    clock = pygame.time.Clock()
    #set frame 
    frame = 0
    draw_color = [0,255,0]
    #reftime = pygame.time.get_ticks()
    text = pygame.font.Font(None,25)
    #start drawing
    while 1:
        clock.tick(30)
        shapetest=shape((320,240),100,'blue')
        shapetest.draw()
        #check if is pressed any key 
        pygame.event.get()
        #if is press escape key
        if pygame.key.get_pressed()[pygame.K_ESCAPE]:
            pygame.quit()
            exit()
        #print clock.get_fps() on windows title
        pygame.display.set_caption(str(clock.get_fps()))   
        pygame.display.update()
        #start fade background
        background_fade()
        #change var frame for background_fade
        frame += 1
        #stop when frame is 100
        if frame == 100:
         break

    frame = 0
    
    pygame.display.update()
    background_fade()

    frame += 1

I make one screenshot to see how it's working.

PyGame : The Star Wars - tutorial from internet.

This web tutorial will show you how to make your Star Wars carnival.
The author of this article - Koldo Santisteban shows us how to deal with the Arduino device and Pygame python module.

PyGame : Using sound, mixer, volume, channels, fade-in and out effect.

PyGame module comes with sound feature and this allows users to test some effects.
The next source code will make a window and also will play a song.
After, You can test all effects with python version 3.4.1.
Just see the keys from source code and test it. The song is an ogg file.
I used this sample from a recording of the album Through the Devil Softly by the artist Hope Sandoval and The Warm Inventions from here.

Let's see the python script:

import pygame, sys

blue = (55, 75, 155)
 
pygame.init()
pygame.display.set_caption('pygame - using sound effect')
size = [460, 100]
screen = pygame.display.set_mode(size)
clock = pygame.time.Clock()
 
# load sound file
pygame.mixer.init(frequency=22050, size=-16, channels=2, buffer=4096)

pygame.mixer.music.set_volume(0.5)
sound = pygame.mixer.Sound("bird.ogg")
snd_array = pygame.sndarray.array(sound)
snd_out = pygame.sndarray.make_sound(snd_array)
snd_out.play()

mychannel=pygame.mixer.find_channel()
while pygame.mixer.find_channel is None: 
    print (pygame.mixer.find_channel)
allchannels=pygame.mixer.get_num_channels()
print ('all channels - ',allchannels)
print ('duration -',sound.get_length(),' seconds')
print ('press 1 - play sound')
print ('press 2 - play sound in a loop')
print ('press 3 - play sound with 9 seconds fade-in effect')
print ('press 4 - play sound just for 9 seconds')
print ('press 5 - play sound 3 more times')
print ('press 9 - stop playing with fadeout effect set 9 ')
print ('press 0 - stop playing instantly')
print ('press up arrow key - up volume')
print ('press down arrow key - down volume')
 
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_1:
                sound.play()
            if event.key == pygame.K_2:
                sound.play(-1)
            if event.key == pygame.K_3:
                sound.play(-1, fade_ms=9000)
            if event.key == pygame.K_4:
                sound.play(-1, 9000)
            if event.key == pygame.K_5:
                sound.play(3)
            if event.key == pygame.K_9:
                sound.fadeout(9000)
            if event.key == pygame.K_0:
                sound.stop()
            if event.key == pygame.K_UP:
                sound.set_volume(sound.get_volume()+0.1)
                print(sound.get_volume())
            if event.key == pygame.K_DOWN:
                sound.set_volume(sound.get_volume()-0.1)
                print(sound.get_volume())
    screen.fill(blue)
    pygame.display.update()
    clock.tick(10)
