1.
In this project, the game needs to be launched fullscreen as soon as Raspberry Pi
(that has been set up to launch the desktop game) is powered up.
2.
The
pygame.display.set_mode
method is used to set the game to fullscreen
with the
pygame.FULLSCREEN
argument. The resoluion of the game will be
(
Window width x Window height
), in this case, 640 x 480 pixels:
DISPLAYSURF = pygame.display.set_mode((WINDOWWIDTH,
WINDOWHEIGHT),pygame.FULLSCREEN)
3. In order to launch the game (the Python script:
Connect_four.py
) ater
Raspberry Pi is powered up, let's create a shell script using a text editor
with the following contents and call it
startup.sh
:
#!/bin/sh
python Connect_four.py
4. The shell script needs to be saved to the
/home/pi
locaion. Alternaively,
the script can be saved at any other locaion.
5. The shell script has to be made an executable file using the
chmod
command:
sudo chmod 755 startup.sh
6. In order to execute
startup.sh
upon boot, the
/etc/rc.local
file needs to
be modified. In the command-line terminal of Raspberry Pi, the file can be opened
using a text editor such as
nano
:
sudo nano /etc/rc.local
7. Before the last line of the file,
exit 0
, the following lines have to be added:
sleep 10
cd /home/pi/
/home/pi/startup.sh &
exit 0
8. The script is executed ater all the kernel modules are iniialized. The script is
executed from the directory where the files have been saved.
