Connect to GameShell via ssh
cpi@192.168.1.112’s password: [type “cpi”]
Linux clockworkpi …
cpi@clockworkpi:~$ pwd
/home/cpi
You can find the address to “ssh" to by navigating to “tiny cloud” in the GameShell. The default username and password are both “cpi”.
Create a folder “downloads” in “/home/cpi/“, where we will place the Miniconda install script later.
mkdir downloads
ls
apps downloads games launcher launchergo music skins
Download Miniconda for Linux and Move to GameShell
I already download the miniconda install script (https://repo.anaconda.com/miniconda/Miniconda-3.16.0-Linux-armv7l.sh, which is renamed miniconda-install.sh) on the computer and thus I just “scp” it to the GameShell. Alternatively, you can of course download the Anaconda install script directly to the GameShell after “ssh” to it.
cd ~/Downloads
~/Downloads >> scp miniconda-install.sh cpi@192.168.1.112:/home/cpi/downloads
Wait until the transferring/downloading process done.
Install Miniconda on GameShell
Login to GameShell and install Miniconda.
cpi@192.168.1.112’s password: [type “cpi”]
Linux clockworkpi …
cpi@clockworkpi:~$ bash downloads/miniconda-install.sh
…
Read the terms and follow the promotions to install Miniconda. Then create the environment, say “first”, install “SDL” ([2]) and “pygame".
cpi@clockworkpi:~$ conda create -n first python=2.7
…
Install SDL ([2])
cpi@clockworkpi:~$ cd downloads
cpi@clockworkpi:~/downloads$ wget http://www.libsdl.org/release/SDL-1.2.14.tar.gz
cpi@clockworkpi:~/downloads$ tar -xzvf SDL-1.2.14.tar.gz
cpi@clockworkpi:~/downloads$ cd SDL-1.2.14
cpi@clockworkpi:~/downloads$ ./configure --prefix=$HOME
cpi@clockworkpi:~/downloads$ make
cpi@clockworkpi:~/downloads$ make install
Install Pygame ([2])
cpi@clockworkpi:~$ source activate first
(first) cpi@clockworkpi:~$ cd downloads
(first) cpi@clockworkpi:~/downloads$ wget https://www.pygame.org/ftp/pygame-1.9.1release.tar.gz
(first) cpi@clockworkpi:~/downloads$ tar -xzvf pygame-1.9.1release.tar.gz
(first) cpi@clockworkpi:~/downloads$ cd pygame-1.9.1release
Comment out the line starting with “_camera” in “Setup”, and then install the “pygame” by running:
(first) cpi@clockworkpi:~/downloads$python setup.py install
Now you can import “pygame”.
(first) cpi@clockworkpi:~/downloads$python
Python 2.7.10 …
import pygame
Create a Game and Start in GameShell
Connect to GameShell and navigate into the games. Create a repository “first_game” for the new game.
(first) cpi@clockworkpi:~$ cd games
(first) cpi@clockworkpi:~/games$ mkdir first_game
Create the pygame script “first.py” in “~/games/first_game".
import os, sys, random, time, datetime, math
import pygame
from pygame.locals import *
from pygame.color import *
GS_KEY_MENU = 27
GS_KEY_X = 117
GS_KEY_Y = 105
GS_KEY_A = 106
GS_KEY_B = 107
GS_KEY_UP = 273
GS_KEY_DOWN = 274
GS_KEY_RIGHT = 275
GS_KEY_LEFT = 276
GS_KEY_SELECT = 32
GS_KEY_START = 13
class First :
def __init__(self) :
self.width = 320
self.height = 240
self.delta = 0.2
self.event = None
def draw(self, screen) :
pygame.display.flip()
screen.fill(THECOLORS["white"])
screen.blit(pygame.font.Font(None, 24).render("Hello world!", 1, THECOLORS["black"]), (10, 10))
screen.blit(pygame.font.Font(None, 24).render("You pressed: %s" % self.event, 1, THECOLORS["black"]), (10, 50))
pygame.display.flip()
def run(self) :
pygame.init()
screen = pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
screen.fill(THECOLORS["white"])
clock = pygame.time.Clock()
running = True
while running :
for event in pygame.event.get():
if event.type == QUIT:
running = False
elif event.type == KEYDOWN :
self.event = event.key
if event.key == GS_KEY_MENU :
running = False
self.draw(screen)
pygame.event.pump()
clock.tick(1 / self.delta)
if name == “main” :
game = First()
game.run()
Then create an entrance shell “11_First.sh” in the launcher of GameShell.
(first) cpi@clockworkpi:~$ cd launcher/Menu/GameShell
(first) cpi@clockworkpi:~$ vi 11_First.sh
The content of “11_First.sh” should be like this.
#! /bin/bash
source activate first
python ~/games/first_game/first.py
You can also make an icon for the new game, say a png picture “First.png”, and put it into “~/launcher/skin/default/Menu/GameShell”.
Reload the UI, and now you should see a new app named “First” in the launcher. Enter it, you will see “Hello world!” followed by a promotion to tell you the code of the last pressed key. If you followed exactly what are given in “first.py”, then you can exit the first game and back to the launcher by pressing the button “MENU” on the GameShell.
That’s all. Happy coding!
