TFS 1.X+ Can someone explain me math.random?

[Marko999x]

Im trying to create my own stuff but im confused at math random now.

I have tried

player:addItem(2160, 10, math.random(10 / 100)) <---- 10% chance to get 10cc is it right like this or not?

im confused
thanks

a example:

if math.random(1, 100) <= 10 then
player:addItem(2160, 10)
end

Math.random(lowerlimit, upperlimit) simple generates a pseudo-random number between those 2 limits (both inclusive).
If used with only a single parameter, the lower limit defaults to 1.

So you could generate a random number between 1-100, and if that number is 10 or lower, then you've hit the 10% lottery.

local chance = 10

if math.random(100) <= chance then
    -- 10% chance succeeded
else
    -- failed
end

More info at lua-users wiki: Math Library Tutorial (http://lua-users.org/wiki/MathLibraryTutorial) -> CTRL+F math.random.
Worth checking out math.randomseed and understanding seeding of random funcs in general as well.

thanks you

math.random() -> calls rand() from C
math.random(3, 10) -> random number (minimum 3, maximum 10)
math.random(100) -> random number from 1 to 100.
