Chance for random table selection

[StormyTerror39]

I want to have a table full of items then have a chance for each item. Something like this
local Items = {
{name = Item, chance = 25},
{name = item2, chance = 50},
{name = Item3, chance = 1}
}
I know that there is table.random but that just chooses a random item. I want it to take the chances that way if an item has a higher chance then it will be chosen more likely

Assuming you're fine with sorting the items table based on chance, something like this'll work.

This is working fine for one item but how could i expand this to choose like 3 items because i have like 10 items set at 100 and 2 items set at 10 and i seem to get the items set at 10 every time

You would just run the same code I posted (everything below line 13) 3 times.

Or if you're always going to pick 3 items then yeah you could use 3 different picks and 3 different sums such that you only have to use 1 loop. This solution seems to be the one you came to.
