ok I think I got it all using slookup except for the equation..... what is the '{' in the equation?

What does slookup say in the dice section of the smaug spell? That'll probably give hints as to what '{' means. I'd help you more if I could, but my version of SMAUG is older than 1.4 and doesn't have that feature...

"Use the Source, Luke ...".

The source gives a clue. Looking at spell_smaug I see this:


/*                                                                  -Thoric
 * Fancy dice expression parsing complete with order of operations,
 * simple exponent support, dice support as well as a few extra
 * variables: L = level, H = hp, M = mana, V = move, S = str, X = dex
 *            I = int, W = wis, C = con, A = cha, U = luck, A = age
 *
 * Used for spell dice parsing, ie: 3d8+L-6
 *
 */
i

I also see:


   switch(operation)
    {
        case '-':               total -= rd_parse(ch, level, sexp[1]);  break;
        case '+':               total += rd_parse(ch, level, sexp[1]);  break;
        case '*':               total *= rd_parse(ch, level, sexp[1]);  break;
        case '/':               total /= rd_parse(ch, level, sexp[1]);  break;
        case '%':               total %= rd_parse(ch, level, sexp[1]);  break;
        case 'd': case 'D':     total = dice( total, rd_parse(ch, level, sexp[1]
) );    break;
        case '<':               total = (total < rd_parse(ch, level, sexp[1]));
        break;
        case '>':               total = (total > rd_parse(ch, level, sexp[1]));
        break;
        case '=':               total = (total == rd_parse(ch, level, sexp[1]));
        break;
        case '{':               total = UMIN( total, rd_parse(ch, level, sexp[1]
) );    break;
        case '}':               total = UMAX( total, rd_parse(ch, level, sexp[1]
) );    break;

        case '^':
        {
            int y = rd_parse(ch, level, sexp[1]), z = total;

            for (x = 1; x < y; ++x, z *= total);
            total = z;
            break;
        }
    }
    return total;

So, it seems to be something to do with the minimum of two numbers. :)

In the game try typing HELP DICEFORMULAS:


To make the special SMAUG spells possible, special dice formula handling
had to be coded in.  (At least to make it nice).  This dice formula code
supports full BEDMAS expressions ( ) ^^ / * + -, plus extra mud related
operators and variables:

D dice         L level          H hit points      M mana
V movement     S strength       I intelligence    W wisdom
X dexterity    C consitution    A charisma        U luck
Y age

Sweet, see I learn something new every day.... Thanks!!

hehe just fyi the {
Dice: l/2 { 40
means that it calculates the number and { is the max :p
so nomatter what blitz maxes out at 40 damage

Nick Gammon Australia Forum Administrator Mon 14 Jul 2003 01:35 AM #8

Looking at the code above, "{" does a UMIN (unsigned minimum).

Thus the damage would be the minimum of intelligence divided by 2, and 40.

So you are right, the maximum is 40, because it takes the minimum of 2 numbers. A bit confusing.
