Good Morning! I have a problem with a Luck Rng system i made
So i made a working, good RNG luck system but i have no clue on how to implement luck on it
Please Help.
return {
GetRandomIndex = function(Chances)
for i, TableValue in ipairs(Chances) do
local RolledNumber = math.random(1, TableValue[2])
if RolledNumber == 2 and TableValue[2] > Chances[3][2] then
return {
TableValue[1];
TableValue[2];
TableValue[3]
}
end
end
return Chances[1]
end,
}
You can use math.random. it generates random number. example: math.random(1,100) (its gonna generate a random in between 1 and 100) Just for the sake of it, copy and paste this script in studio. When you check the output you will see that it printed a random number.
local random = math.random(1,100)
print(random)
You can use Youtube tutorials for a deeper explanation, it’ll help you implement it to your system
Im not sure if you understand. Im trying to make a higher chance for a higher number
depending on whether you use weights for chances, you can simply add values to the weights themselves rather than specifically modifying the random num. gen.
local luck = 0
local max = 100 -- 1 in 100
print(math.random(1, max) <= 1 + luck) -- 1 + luck in 100 chance of printing true
Please can you give me an example
a bit complicated to show depending on the use case, but here’s a sum up;
local luckmodifier = 0; -- positive numbers = higher chance of getting lower-weight items
local totalweight = 0; -- internal rng stuff
local weights = {
{
baseweight = 1;
item = 'rare item';
};
{
baseweight = 5;
item = 'uncommon item';
};
{
baseweight = 10;
item = 'common item';
};
};
function getWeightedItem()
totalweight = 0;
for _, v in weights do
v.weight = v.baseweight + luckmodifier;
totalweight += v.weight;
end;
local rng = math.random(1, totalweight);
local currentweight = 0;
for _, v in weights do
currentweight += v.weight;
if rng <= currentweight then
return v.item;
end;
end;
end
basically because you set everythings’ weight up, the lower-weighted items appear ‘more often’ as a direct result of luck. that’s more of a math thing, you can check out statistics and stuff.
edit to explain it ‘better’ in a way;
if u add +100 luck, rare will have a weight of 101 and common will have a weight of 110. yeah, statistically common will still show up a bit more often, but now the chances are almost the same with a +100 luck modifier
