When I use droolingzombie to test the health bar, it result a very long decimal, I want to convert it into an integer. Any solution?
local player = game.Players.LocalPlayer
local humanoid = player.Character:WaitForChild("Humanoid")
local Label = script.Parent
while true do
local health = humanoid.Health
Label.Text = health
wait(0,1)
end
How to convert a decimal into an integer?
I assume you're asking how to round a number.
We can use the formula floor(x + 0.5) to floor a number. Lua 5.1 has a math library with a floor function so we can use that.
All you have to do is call floor(health + 0.5) and then set the text to that!
###Example Code
This will output 5 because 5.251515215151 rounds down.
local floor = math.floor
local number = floor(5.251515215151 + 0.5)
print(number)
I use math.floor(health) and it result the same with math.floor(health + 0.5) so what does 0,5 do?
.5 is for the rounding.
ok i get it, it round numbers
You can use a rounding function like math.floor
local player = game.Players.LocalPlayer
local humanoid = player.Character:WaitForChild("Humanoid")
local Label = script.Parent
while true do
local health = humanoid.Health
Label.Text = math.floor(health + 0.5) -- Rounds decimal
wait(0,1)
end
Or if performance is a must;
local player = game.Players.LocalPlayer
local humanoid = player.Character:WaitForChild("Humanoid")
local Label = script.Parent
while true do
local health = humanoid.Health
Label.Text = health + 0.5 - (health + 0.5) % 1 -- Rounds decimal
wait(0,1)
end
