Hello.

I created this thread so people can show some interesting games made using scripting languages.

The basic rules are:

- The code must be in a scripting language, be it bash, perl, lua, python, or whatever you can think of.

- The code must fit in a single post. You are not allowed to split the game into multiple posts or add attachments.

- Also related to the above rule, the less lines the better.

- The code you post here must be written by you, and by making it available here you put it in the public domain.

That's about it I think.

Heres one to get you started.

Code:

#! /bin/sh

ntries=0;
targetnum=$(((RANDOM%10)+1));

while [ $ntries -lt 10 ]; do
    echo -n "Type a number between 1 and 10 inclusive:";
    read num;
    test "$num" || exit;
    num=$((num));
    ntries=$((ntries+1));
    if [ "$num" -eq $targetnum ]; then
        echo "Congrats pal! You got it in $ntries attempts!";
        exit;
    elif [ "$((num))" -gt $targetnum ]; then
        echo "Target number is lower.";
    else
        echo "Target number is higher.";
    fi
done

echo "You didn't make it in 10 attempts...";

$RANDOM is a bashism, so should be #! /bin/bash or something really hacky using /dev/random

space invaders would actually be possible in shell using color formatting and storing positions of objects in a bash array to store the positions/conditions of the "sprites" ... mazes, snake, tetris are the easier ones but defender and galaga are even scriptable

I have actually been contemplating writing a mini game engine in shell that simply modifies an svg image (I have have code for automatiacally refreshing an image when the file is modified as part of my simple icon tray - which, btw, I PD'd along with the most permissive license I could come up with for locations that don't recognize public domain ) Pretty much any 2d game you could think of could be rendered using a single svg thanks to "include", but I have not seen too many PD svgs around, so I have been collecting ISC/MIT/BSD/UIUC licensed ones that I come across.

okay, that would be cool.
But the idea of this post is to make something like Speedhack.

I'm working myself in some tiny platform game using ANSI escape sequences for graphics. I don't know if every (virtual) terminal out there supports these, but I'll post it when I fix some minor things.

A game I recommend is 'Columns'

J-K-L keys are used for movement

It's possible to run it in mini vMac emulation.

I put it in the archive package to download. Everything
needed is in the package. Follow instructions.

can it run on Bash?

heres a pointless script-
Code:
#! /bin/bash
#define board pieces
  strpieceX=".XXXXXXXXXXXXXXXXXXXXXXXXXXXX."
strpiece[0]=".X.....X......" && strpiece[1]="............X."
strpiece[2]=".X..X........." && strpiece[3]="......XX......"
strpiece[4]=".X..........X." && strpiece[5]=".........X..X."
strpiece[6]=".X............" && strpiece[7]="......X.....X."
strpiece[8]="......X..X...." && strpiece[9]="....X..X......"

#set board
for (( i=0; i <= 9; i++ ))
do
  stpiece[i]="X"${strpiece[$((RANDOM%10))]}${strpiece[$((RANDOM%10))]}"X"
done
#greeting
echo
echo Hello, I am the random Monkey Man!
echo
echo $strpieceX
for (( i=0; i <= 9; i++ ))
do
 printf ${stpiece[$i]}
 echo
done
echo $strpieceX
echo
#monkey business
echo -n "Can you guess the name of the map?  ";
read str;
if [ $((RANDOM%2)) -eq 0 ]
then
  echo "I can not believe you guessed '"$str"'."
  if [ $((RANDOM%2)) -eq 0 ] ; then echo "very bad!"; fi
else
  echo -n "Correct answer..."
  if [ $((RANDOM%2)) -eq 0 ]
  then
    echo "but no gold for you, sorry."
  else
    echo "take 10 golden coins, well done, your welcome."   
  fi
fi
echo Now be on your way!!!
echo

How about Mastermind?
I'm not a big fan of this game, but I can't come up with anything more interesting right now...
Here's my crude, textual version:

Code:
#!/bin/bash

# Simple implementation of Mastermind by SFR'2012

# ===========================================
SET=A-F         # Set of letters, max. A-Z
LENGHT=4      # Lenght of the code, max. 10
ATTEMPTS=12      # Number of tries
# ===========================================

C='!!!!!!!!!!'
W='??????????'
U='..........'
LEN=$(($LENGHT-1))

for i in `seq 0 $LEN`; do CODE[$i]=`cat /dev/urandom | tr -dc $SET | head -c 1`; done

clear
echo "The $LENGHT-character code out of $SET set has been generated."
echo "The code may contain repetitions."
echo "Try to guess it within $ATTEMPTS attempts!"
echo
echo "! - indicates the existence of a correct letter in the correct position."
echo "? - indicates the existence of a correct letter in the wrong position."
echo
echo "Lenght: $LENGHT   Set: $SET   Attempts: $ATTEMPTS"
echo

N=1

while [ $N -le $(($ATTEMPTS)) ]; do

  while true; do
    read -p "Attempt $N: " KEY
    [ "$KEY" = "." ] && exit
    TEST=`echo $KEY | tr [:lower:] [:upper:] | tr -dc $SET`
    [ "${#TEST}" -eq $LENGHT ] && break
    echo -e "\033[2A"
  done

  CODE_TEMP=( "${CODE[@]}" )
  for i in `seq 0 $LEN`; do KEY_TEMP[$i]=`echo "${TEST:$i:1}"`; done

  CORRECT_POS=0
  for i in `seq 0 $LEN`; do
    if [ "${CODE_TEMP[$i]}" = "${KEY_TEMP[$i]}" ]; then
      CORRECT_POS=$(($CORRECT_POS+1))
      CODE_TEMP[$i]=".1"; KEY_TEMP[$i]=".2"
    fi
  done
 
  WRONG_POS=0
  for i in `seq 0 $LEN`; do
    for j in `seq 0 $LEN`; do
      if [ "${CODE_TEMP[$i]}" = "${KEY_TEMP[$j]}" ]; then
        WRONG_POS=$(($WRONG_POS+1))
        CODE_TEMP[$i]=".1"; KEY_TEMP[$j]=".2"
      fi
    done
  done
 
  [ "${#N}" -eq 1 ] && N="0"$N
  echo -ne "\n\033[2A"$N") "${TEST[@]}" : "
  echo "$C" | head -c $CORRECT_POS; echo "$W" | head -c $WRONG_POS; echo "$U" | head -c $(($LENGHT-$CORRECT_POS-$WRONG_POS))
  echo "           "
 
  [ "$CORRECT_POS" = "$LENGHT" ] && echo -e "\nCongratulations! You made it in $N attempt!" && exit
  N=$((10#$N+1))
done

echo -ne "\nSorry, you didn't make it. The code was: "
echo "${CODE[@]:0}" | tr -d " "
exit


Greetings!

Try to guess it within 12 attempts!

! - indicates the existence of a correct letter in the correct position.

Lenght: 4 Set: A-F Attempts: 12

This isn't completely tiny but here it is complete with a GUI.
It plays tictactoe and does a fairly good job of it.

Code:


#/bin/bash

DF=/tmp/tic
BB="X23456789"
W=false

function tot() {
  Y=$(echo "${BB:$2:1}${BB:$3:1}${BB:$4:1}" | sed "s/[1-9]//g;s/X/+1/g;s/O/+10/g")
  case $(( 0 $Y )) in
    0) eval $1=1
      ;;
    1) eval $1=2
      ;;
    10) eval $1=2
      ;;
    2) eval $1=1000
      W=true
      ;;
    20) eval $1=10
      ;;
    30) echo "You win!"
      exit
      ;;
    *) eval $1=0
      ;;
    esac
  }

function but() {
  local Z
  if [[ "$1" > "A" ]] ; then
    Z=text
  else
    Z=button
    fi
   
  echo "<$Z><label>$1</label></$Z>"
  }

function dia() {
  local I
  local J
  echo "<vbox>"
  if [[ "$1" != "" ]] ; then
    echo "<text><label>$1</label></text>"
    fi
  echo "<hbox>"
 
  for I in 0 1 2 ; do
    echo '<vbox homogeneous="true">'
    for J in $I $(( $I + 3)) $(( $I + 6 )) ; do
      but ${BB:$J:1}
      done
    echo "</vbox>"
    done

  echo "</hbox>"   

  if [[ "$2" != "" ]] ; then
    echo "<button><label>$2</label></button>"
    fi
     
  echo "</vbox>"
  }

MX="your move"
while true ; do
  if ( echo $BB | grep -v -r -q "[1-9]" ) ; then
    dia "Its a draw" "OK" >$DF
  else
    dia "$MX" >$DF
    fi
  M=$(gtkdialog3 -f /tmp/tic)
  if ! (echo "$M" | grep -q "[1-9]") ; then
    exit
    fi
  M=${M/EXIT/M}
  eval $M
  BB=${BB/$M/O}
  for X in "A 0 1 2" "B 3 4 5" "C 6 7 8" "D 0 3 6" "E 1 4 7" "F 2 5 8" "G 0 4 8" "H 2 4 6" ; do
    tot $X
    done
  M=$( echo "$((2 + $A + $D + $G )) 1 ${BB:0:1}
$(( $A + $E )) 2 ${BB:1:1}
$((2 + $A + $F + $H )) 3 ${BB:2:1}
$(( $B + $D )) 4 ${BB:3:1}
$(( $B + $E +$G + $H )) 5 ${BB:4:1}
$(( $B + $F )) 6 ${BB:5:1}
$((2 + $C + $D + $H )) 7 ${BB:6:1}
$(( $C + $E )) 8 ${BB:7:1}
$((2 + $C + $F + $G )) 9 ${BB:8:1}
" | grep -r "[1-9]\$" | sort -n | tail -1 | cut -d\  -f2 )
  MX="I moved $M"
  BB=${BB/$M/X}
  if $W ; then
    dia "I win at $M" "OK" >$DF
    gtkdialog3 -f /tmp/tic
    exit

I would be nice if you quoted a bit of what you are reacting to. I went and looked at my code and lines 21-23 do serve an important purpose. I assumed that the user would look at the code before running it. Those lines serve to give a false hope of winning.

I thought outside the box a bit and just created a poor man's scriptable game framework... would be cool to have some kind of a contest

Sory for the delay guys, I exceeded my bandwidth Sad
Really nice games.
Been a bit busy "working", so I didn't have time to finish anything.
A new game coming soon...
