Hello, I'm just not sure how you could do precentage chance which means for example 15% chance of getting an item. I found an way to do it, but I'm sure there are better ways to do this. The code I found:
local chance = 15
if math.random(1,100) < chance then
--Give item
else
--Do not give item
end
Thanks for All Answers and Excuse me my poor English.
The only way to produce "randomness" in Lua is math.random. math.random can be used in three ways (all which produce completely uniform results):
math.random(low, high) produces a random integer between low and high (inclusive)math.random(high) produces a random integer between 1 and high (inclusive)math.random() produces a random real between 0 and 1 (including 0 but not including 1)Thus, all of the following have a 15% chance of being true
math.random() < 0.15
math.random(1, 100) <= 15
math.random(100) <= 15
The first one is nice, because it will work neatly with fractional percentages.
You could wrap this up into a function like this:
function chance(percentage)
return math.random() < percentage / 100
-- or equivalently, math.random() * 100 < percentage
end
if chance(15) then
print("15% of the time")
else
print("85% of the time")
end

This is the most effective way... and the simplest. The % Sign returns some number if it is possible to multiply it by a whole number to get that number...
