Why doesn't this work?

Code:

random_seed(0);
value = integer(random(6));
my.skin += value;

I read what I could in the manual about this particular 'thing' and came up with nothing more than more confusion as to why this doesnt work........

just off the top of my head,
I think

Code:

value = integer(random(6));

should be

Code:

var value = integer(random(6));

unless you already defined value earlier.

try

Code:

random_seed(0);
value = integer(random(6)+1);
my.skin += value;

Sorry I was a bit vague.

This action is used on 50+ models.
If I remove the random_seed(0); I get the same result each time (their skins will randomize, but always be the same random value [as the manual says it would]).

with the random_seed(0) all skins stay the same color.

@xbox: yes, its been defined

@malice: I tried your idea, but it didnt work

I've done this before in the past and it worked fine. Strange how such a thing can happen..

How about running random_seed(0) once in the main function fallowed by a wait and remove it here

Also debug_var the value of "value" lol

also debug skin to see if it chages or exceeds the number of skins
i=my.skin;
debug_var(i);

I put the random_seed in the main function... but I think the issue was because they were created and built with WED. I created some more models at runtime and their skins changed randomly..

Just do this:

Code:

var rndSkin = 0;
rndSkin = integer(random(6));
my.skin = rndSkin + 1;

Also note that random(6) will create value between 0-5, so thats why I add 1 to the skin at th end. I'm not sure about using 'random_seed' over and over again, it works great for me if I add it once in the main function.

Random number generators always follow the same pattern, which means that when the last generated value is known you can always predict the next one, it's a machine after all.
Let's say you have such a function
int random_base(int seed);
which outputs a value between 0 and 65000, then your default random(var range) will be calculated somewhat as follows if I'm not mistaken:

Code:

var random(var range)
{
  var value;

  seed = random_base(seed);
  value = seed/65000.0*range;

  return value;
}

where seed is some global integer. You can change the seed number by calling random_seed(int num), and when you call the latter with num = 0, I assume the computer will take some additional information like the system's time (at game start) or something like that.
If you call random_seed() over and over you mess with the random(_base) pattern and in the worst case just get the same number over and over.
