First of all, hello.

I want to make a percentege system for my game, the problem? I can’t figure out how to make it.

Example on what i want to do:

Loot1: 25%
Loot2: 50%
Loot3 = 30%
Loot4 = 10%

Thanks for reading.

U could use math.random(x, y) for example. 25% = (1, 4) . 50% = (1, 2) You would want the function to find the number 1.

The solution here should help you. :slightly_smiling_face:

i dont think math.random would be a good option because It’s completly random ut i will try it, thanks

math.random would be a good option, and I have helped making loot tables before, but here’s an example:

local loottable = {
    Loot1 = 25,
    Loot2 = 25,
    Loot3 = 30,
    Loot4 = 10
}

local totalrarity = 0

for i,v in pairs(loottable) do totalrarity += v end

function getloot()
    local lootnum = math.random(totalrarity)
    local currentrarity = 0
    
    for i,v in pairs(loottable) do
        currentrarity += v
        
        if lootnum <= currentrarity then return i end
    end
end

print(getloot())

Now, there are multiple other ways to make the table, but this is just one going based off of how you provided the loot system.
