Rock Paper Scissors

I'm trying to create this game in Unix.

This is what I have so far:

Code:
echo "Player one: Choose (R)ock, (P)aper (S)cissors"
stty -echo
read Pone
case $Pone
in
R) echo "Good Choice! Let's see what Player two chooses.";;
P) echo "Good Choice! Let's see what Player two chooses.";;
S) echo "Good Choice! Let's see what Player two chooses.";;
*) echo "Please choose only R,P or S.";;
esac
 
echo "Player two: Choose (R)ock, (P)aper (S)cissors"
stty -echo
read Ptwo
case $Ptwo
in
R) echo "Good Choice! ";;
P) echo "Good Choice! ";;
S) echo "Good Choice! ";;
*) echo "Please choose only R,P or S.";;
esac

I need to be able to take both inputs and give it a value 1,2,3,or4 so I can use those values for the possible combination of the outcome. Any suggestions would be appreciated.

P.S. Does anyone know how to cut and paste between virtual machine and your actual machine?

No... but they can have disk space in common (NFS)...
IMHO its the second that should do the processing then send output to both StdOut

Start by doing a decision tree/table
You will see more clear...

Tree was the answer

Thanks VBE,

I made a tree and was able to see it much clearer. I made 4 seperate scripts using case statements. Now my assignment is complete.

Now i got addicted to this stuff and want to add a scoring system where i can append a score. Any ideas?

Hi,

here's my version of RPS. I tried to get basic functionality for keeping track of the score. Of course, there's still much to improve, but that's your job Smilie

Code:
#!/bin/bash

# Load score from files player1.score and player2.score, if they exist.
# Otherwise leave them 0.

p1_number_of_victories=0
p2_number_of_victories=0

if [ -e player1.score -a -e player2.score ]; then
        p1_number_of_victories=`cat player1.score`
        p2_number_of_victories=`cat player2.score`
fi

function p1_wins() {
        p1_number_of_victories=`expr $p1_number_of_victories + 1`
}

function p2_wins() {
        p2_number_of_victories=`expr $p2_number_of_victories + 1`
}

abort_game=n

until [ $abort_game = y ]; do
        PS3='Choose your action, player 1: '
        select action1 in "Rock" "Paper" "Scissors"; do break; done
        PS3='Choose your action, player 2: '
        select action2 in "Rock" "Paper" "Scissors"; do break; done

        case $action1 in
        "Rock")
                case $action2 in
                        "Rock") echo "Draw";;
                        "Paper") echo "Player 2 wins"; p2_wins;;
                        "Scissors") echo "Player 1 wins"; p1_wins;;
                esac
                ;;
        "Paper")
                case $action2 in
                        "Rock") echo "Player 1 wins"; p1_wins;;
                        "Paper") echo "Draw";;
                        "Scissors") echo "Player 2 wins"; p2_wins;;
                esac
                ;;
        "Scissors")
                case $action2 in
                        "Rock") echo "Player 2 wins"; p2_wins;;
                        "Paper") echo "Player 1 wins"; p1_wins;;
                        "Scissors") echo "Draw";;
                esac
                ;;
        esac

echo "Do you want to quit the game? [y/N]"
read abort_game
if [ -z "$abort_game" ]; then abort_game=n; fi # -z: input is empty -> ENTER was pressed

done
# end of loop

# Write new score to .score files
echo $p1_number_of_victories > player1.score
echo $p2_number_of_victories > player2.score

# exit gently
exit 0
