I've noticed the Or (||) operator will trigger an action in an if statement if one or both are true. I think an XOR operator, which would trigger the if statement if one but not both are true, would be very useful in scripting.
but, you can do that easily with the actual && and || operators, cant you?... ::)
like if ((a==1 && b==0) || (a==0 && b==1))...
Easier than that: a logical XOR is the != operator...
0 != 0 gives 0
0 != 1 gives 1
1 != 0 gives 1
1 != 1 gives 0
of course, each side must be 0 or 1 for this to work.
It might be nice to have bitwise operators sometimes, though like &, | and ^

There are bitwise AND and OR already, but still missing the NOT and XOR ones. :P
For NOT you can use a simple subtraction and with it you can build a xor function:
// for 16 bit integers
#define MAXINT 2147483647
function not (int a)
{
return MAXINT - a;
}
function xor (int a, int b)
{
return (not ((a & b) | (not (a) & not (b))));
}
Adding missing operators MOD, NOT and XOR is on my to-do list. Are there any other common operators that the script is missing, while we're at it?

thanks for the quick tip :)

left/right shifting operators could come in handy provided it's not some hassle to implement those of course.
shift 1 bit left: *2
shift 1 bit right: /2
Yep, that's how I've done it so far. However, it's an arithmetical shift and I'd also like to see a logical shift (right direction with leading 0s) too. Again it can be workarounded but anyway those I'd like to suggest to be built in AGS. Would be cool to have them as operators with proper type conversion (again if it's not too much work with script engine-related code).
