Programming Forums - Testing outcomes in a dice game

Hello everyone!

I've been coding a dice game and have run into a bit of trouble. My dice game works like this:

1: First the user makes a deposit by clicking an image ($500, $600 etc)

2: The user then makes a bet (of either $100 or $200)

3: The user then makes a prediction on the outcome of the dice roll (1-4, 5-8, 9-12)

4: The user then clicks a button which "rolls" two dice.

5: The total of the two dice detemines whether they win or lose. Eg. If the dice roll total equals 5, and the user predicted an outcome of 5-8, they win.

I am stuck on no. 5 - I need to compare the prediction to the dice roll total to see if the user has won or lost. I am hopelessly stuck.

I was thinking of somehow making the prediction 1-4 equal 'a' and then the dice rolls 1, 2, 3 and 4 equal to 'a' as well so that I can test to see if they match. 5-8 would be 'b' and 9-12 would be 'c', the rolls of 5, 6, 7 and 8 would equal 'b' etc. But how can I do it?

Here's my code for the prediction bit:

<form name="choice">

<P><B>Pick your outcome:</B></P>

<input type="button" name="outcome1" value="1-4" onmousedown="no_choice()" onClick="user_choice = 1, document.chosen.userchoice.value='1-4', pick()">

<input type="button" name="outcome2" value="5-8" onmousedown="no_choice()" onClick="user_choice = 2, document.chosen.userchoice.value='5-8', pick()">

<input type="button" name="outcome3" value="9-12" onmousedown="no_choice()" onClick="user_choice = 3, document.chosen.userchoice.value='9-12', pick()">

</form>



<form name="chosen">

<input type="text" name="userchoice" value="" size="4">

</form>



<script language="JavaScript">

var user_choice = 0

function pick(form) {

if (user_choice == 1) {

alert("You have chosen 1-4") }

else {

if (user_choice == 2) {

alert("You have chosen 5-8") }

else {

if (user_choice == 3) {

alert("You have chosen 9-12") }

}}}

</script>

And the script for my dice roll bit is:

<script language=JavaScript>

function dice_roll() {

var randice = new Array

randice[0] = "images/1.gif"

randice[1] = "images/2.gif"

randice[2] = "images/3.gif"

randice[3] = "images/4.gif"

randice[4] = "images/5.gif"

randice[5] = "images/6.gif"

var ranimage=Math.round(Math.random()*5)

var ranimage2=Math.round(Math.random()*5)

document.randoimage2.src=randice[ranimage2]

document.randoimage1.src=randice[ranimage]



var dice_total = (Number(ranimage) + Number(ranimage2) + 2);

alert("Your roll = " + dice_total);

}

</script>

Can anyone lend a hand? I'm getting so frustrated! If you want to see my "almost working" prototype for the game click: HERE

Thank you!
