end

i need to use the item1, item2, item3 and item4 variables outside the function

how can i do that

[DasKairo (Cairo)]

1. Declare the variables outside the function, and grab the data inside the function

local i1, i2, i3, i4

local function ex()
    i1 = 1
    i2 = 2
    i3 = 3
    i4 = 4
end

2. return the data using return

local function ex()
    return 1, 2, 3, 4
end

local i1, i2, i3, i4 = ex()
-- assigns variables with returned data accrodingly

return essentially pulls data from the function while ending it aswell.

@DasKairo

return 1, 2, 3, 4

OH MY GOD THANK YOU YOU’RE THE BEST I BEEN TRYING FOR 5 HOURS
