Help with randomizing

[wtfraven]

I am attempting to make a bloodlines mod that allows for a chance to have mothers pass on the trait. I have found weight as a possible randomizer and I have seen random but that seems like it refers to a random variable in a set of variables. Is there a way to add in a simple rng and if statement to enable this?

Something like

Random { 1 4 }
if = 1 {
if = {
limit = {
mother = {
has_trait = alcimachid
}
NOT = {
has_trait = alcimachid
}
}
add_trait = alcimachid
}
}

or could I use
if random_attribute=charisma
{
if = {
limit = {
mother = {
has_trait = alcimachid
}
NOT = {
has_trait = alcimachid
}
}
add_trait = alcimachid
}
}

Im basically trying to put a 25% chance to pass the bloodline matrilineally.

You can "roll" a random number like this:

set_variable = {
        name = d100_result
        value = {
            integer_range = { min = 0 max = 100 }
        }
}

if = {limit = {d100_result < 25} ... }

But in your case random list would probably be better:

random_list = {
            25 = {
                trigger = {            
mother = {
has_trait = alcimachid
}
NOT = {
has_trait = alcimachid
}
                }
                add_trait = alcimachid
            }
           75 = {}
}
