integer usage

[the_bob]

ok, i'm trying to make a simple text based game, but i keep getting an error when I try to call a function. Here's my code..

<script>
var health=15;
var strength=30;
var defence=10;
var m1health=16;
var m1strength=30;
var m1defence=4;

funtion attack()  {
	if health > 0  {
		 alert("You attack the monster for " + strength - m1defence + "damage.");
		 alert("You have " + health + "health left.");	
		 alert("Your opponent has " + m1health + "left.");	

	}   else    {
		 alert("You are dead.  You may not attack.");
}
</script>

My guess is that i messed up trying to subtract. I don't recall seeing that in a book or on a website.

alert("You attack the monster for " + strength - m1defence + "damage.");

is that the part that is wrong?

Hi there the_bob

You just have a few ommissions...

<script [color=red]type="text/javascript"[/color]>
var health=15;
var strength=30;
var defence=10;
var m1health=16;
var m1strength=30;
var m1defence=4;
fun[color=red]c[/color]tion attack()  {
	if[color=red]( [/color]health > 0 [color=red])[/color] {
		 alert("You attack the monster for " +[color=red] ([/color]strength - m1defence [color=red])[/color]+ " damage.");
		 alert("You have " + health + " health left.");	
		 alert("Your opponent has " + m1health + " left.");	

	}   else    {
		 alert("You are dead.  You may not attack.");
}
[color=red]}[/color]
</script>

thanks coothead, that gets it working, but i just realised i forgot to make it calculate damage I tried this but i get another error.

function attack()  {
	if( health > 0 ) {
		 alert("You attack the monster for " + (strength - m1defence )+ " damage.");
		 alert("Your opponent has " + (m1health - (strength - m1defence)) " left.");	

	}   else    {
		 alert("You are dead.  You may not attack.");
}
}</script>

Hi there the_bob,

Your code was minus a +

alert("Your opponent has " + (m1health - (strength - m1defence))[color=red] +[/color] " left.");

*feeling pretty stupid about now*
thanks coothead, works perfectly


but now, yet another question; is there any way to change the value of the variable? for example,

var a = 5
var b = 8

if i add a and b, i will get 13. Is there any way to have that change the value of a from 5 to 13?

[coothead]

Hi there the_bob,

var a=5;
var b=8;
var a=a+b;

cthead

[JAVAEOC]

this should also work:
a+=b

[the_bob]

ok, I changed the code to

alert("You attack the monster for " + (strength - m1defence )+ " damage.");

var m1health = (m1health - (strength - m1defence));		
alert("Your opponent has " + m1health + " left.");

now it is saying "Your opponent has NaN left."
thats not cool

[RadarBob]

var m1health = (m1health - (strength - m1defence));

You're declaring then using the variable mlhealth all on one statement. This doesn't make sense.

Actually you're redeclaring an existing variable. Get rid of the var

[the_bob]

Ahh, that makes sence. and it works!
thanks
