QR Turtle update

Paul Sutton / April 20, 2014 / Comments Off

A few months ago I was working on a program to scan qr codes with specific text (e.g forward10) and pass this on to turtle graphics. I have now updated the repository with 4 new codes to allow for the fact I had to modify the program a little as 5 , 10 pixels are too short a distance to really notice

https://github.com/zleap/qrturtle

Now has 4 new png files for 25,50,75 and 100 pixels.

The QR codes were generated from the website at

https://www.the-qrcode-generator.com/

Forward25.png

The main program can now work more logically as there is now a code that says Forward25 which can be linked to the right turtle command rather than using my work around where scanning Forward10 moves 25 as that distance is easier to see on the canvas.

If you want to have a go please feel free to download the code, If you look at https://github.com/zleap/nestedloops there is code to save the graphics canvas as a file.

Source code

basic nested loop using turtle graphics and python
#added input checking
import turtle
import time
 
#set file name
fname= raw_input("Filename (must include .eps ")
#fname="dial.eps"
 
and
 
ts = turtle.getscreen()
ts.getcanvas().postscript(file=fname)
 
print "Saved image to: ", fname
print "All done. Click image to exit."
 
turtle.exitonclick()

Nethack: Vulture-Eye

Paul Sutton / April 18, 2014 / Comments Off

NetHack is a classic Unix game which is very popular among hackers

Vultures eye is a port that is based on Falcons eye and essentially keeps this project going just with a new name and based on the newest build of nethack 3.4.

The game can be downloaded from

http://www.darkarts.co.za/vulture

If you are using ubuntu you need 2 of the Ubuntu deb(ian) packages

vulture-nethack_2.3.67-1_i386.deb and vulture-data_2.3.67-1_all.deb

Once downloaded save to a useful location e.g ~/vulture

You need to install the data first otherwise you get an error

sudo dpkg -i vulture-nethack_2.3.67-1_i386.deb
sudo dpkg -i vulture-data_2.3.67-1_all.deb

Run with vulture-nethack

You can download the source code from github and compile your self which does open up the possibility this can run on the raspberry pi which would be cool.

man page called up with

man vulture-nethack

PrBoom – Open source DOOM

Paul Sutton / April 18, 2014 / Comments Off

Prboom is a clone of the ID software doom software, which since being released as open source software has allowed the game to be ported to more platforms and kep

t alive in various forms.

http://prboom.sourceforge.net/

Thus far I have

Got this installed o

n both my main desktop PC and raspberry pi

Copied the main doom wad file to both systems, this did require using sudoi to copy files over.

It was easier to copy to my pi in the following way

copy wad file to home directory on the pi

copy to required location which if you READ the documentation is

/usr/local/share/games/doom/

i have also added an alias in .bash_aliases

alias doom=’prboom’

See my blog post for more info on .bash_aliases

I can now type doom rather than prboom to run the game.

useful other options

prboom -nofullscreen

RELATED HACKING

If you remember the original doom, there was a menu in dos that allowed you to set the various command line options for the game, hit ok and have these passed over when the game is run

prboom also has the same options and a few others

man prboom

I am therefore trying to create a similar mini front end. Having never done this sort of thing before Gordon Henderson has suggested using whiptail for the menu.

Thus far I have

#whiptail –title “Example Dialog” –yesno “This is an example of a yes/no
#box.” 8 78

#exitstatus=$?
#if [ $exitstatus = 0 ]; then
# echo “User selected Yes.”
#else
# echo “User selected No.”
#fi
#
#echo “(Exit status was $exitstatus)”
#
whiptail –title “Check list example” –checklist \
“DOOM OPTIONSs” 20 78 4 \
“respawn” “Respawn Monsters” OFF \
“no monsters” “No Monsters” OFF \
“no sound” “Disable Sound” OFF \
“no music” “Disable Music” OFF \

Which produces the following.

All this does at present is send the choices to standardERR

Housekeeping on website

Paul Sutton / April 18, 2014 / Comments Off

I am starting to do some cleaning up on this site. Removing pages that are either replicated elsewhere or are no longer needed. Some pages have been copied / pasted to posts and are scheduled for publication later this evening.

Hopefully get a leaner site as a result.

As the leader of an ancient civilization, you must gather the resources you need to raise a military force and dominate your enemies.”

Torbay Pi jam write up.

Paul Sutton / April 12, 2014 / Comments Off

12th April

Again we had a mix of things going on, Tom Brough brought Bob along, with more improvements / enhancements from last time. He can walk and was set in guard dog mode, which those of you who attended the last Exeter Jam will know he just sits there until activated by movement detected by the ultrasonic sensor. Most of the enhancements are with the walking mechanism.

Gordon Henderson Demonstrated the Fuzebox, with more enhancements to FuzeBASIC, it now integrates with Minecraft and has a host of other features, so any school getting Fuzebox will have lots of great things to do with it. It looks well worth the investment.

Myself and Tom also got Xubuntu 13.10 up and running on a old netbook, not quite pi but the pi jams double up as Linux user group meets so we can still support anyone with Linux related issues (the Pi runs Linux, after all). So that is another Windows box that may well one day not run windows. I also demonstrated toms Helicopter game and gave one of the young people the github details to download it.
