Dice script

[Wolfe Deckard]

Hi there

Im looking for a way to create a dice script that will generate a number between -4 and +4 and including 0 so a range of -4,-3.-2,-1,0,1,2,3,4.  Any input will be greatly appreciated.

 

Thanks

This might be one way to do it:

       integer n = (integer)llFrand(10.0);
//generate a float between 0.0 and 9.999....99.  Converting it to an integer rounds down, so you have an integer between 0 and 9
        integer iRandom = -4 + n;

Or, written another way

integer RndX =  4  - (integer) llFrand(9.0);

Edit:  Thanks, Innula

I think you mean (integer) llFrand(9.0)  llFrand(10.0);  Rolig.  The die has 9 faces, including the 0.

Right you are.  Fixed.....  ^^

just curious, why does 4 minus 0 = -4?  lol

i would have thought you would need to do integer RndX =  -4  + (integer) llFrand(9.0);

"-4 + rand" is mathematically equivalent to "4 - rand"

Where did you get 4 - 0 = -4?

Isn't it equal to "+rand -4" instead?

So ..... 

if (integer)llFrand(9.0) == 0, RndX = 4

if (integer)llFrand(9.0) == 1, RndX = 3

if (integer)llFrand(9.0) == 2, RndX = 2

if (integer)llFrand(9.0) == 3, RndX = 1

if (integer)llFrand(9.0) == 4, RndX = 0

if (integer)llFrand(9.0) == 5, RndX = -1

if (integer)llFrand(9.0) == 6, RndX = -2

if (integer)llFrand(9.0) == 7, RndX = -3

if (integer)llFrand(9.0) == 8, RndX = -4

And yes, it doesn't make any difference which way you do the math.  Innula's way and mine are the same.  I was just trying to show the OP an alternate way of writing the same thing.

 Akk.. I meant llFrand(10.0) (as in my example)!

Sorry all.

thanks, everyone!

I don't know if this is any use to you as well, but Firestorm Viewer includes a dice feature - see https://wiki.phoenixviewer.com/fs_dice

You learn something new every day, I had no idea that was even there

heh, sry, was just codeblind.. dunno, i finally get it.. 4 - 8 = -4!
