Rounding a Vector3 String Value to a whole number?
This basically just sets the TextLabel's text to the player's torso's coordinates. The values are too big and I have no idea on how to round it.
This is an example of what the TextLabel looks like: https://gyazo.com/acc5d71abfffceff8d89b38baea20cb9
How would I round the X, Y, and Z values so they are always whole numbers?
LocalScript inside of a TextLabel
01 | local player = game.Players.LocalPlayer |
02 | local character = player.Character |
03 | if not character or not character.Parent then |
04 | character = player.CharacterAdded:wait() |
05 | end |
06 |
07 |
08 | while wait(0.001) do |
09 | script.Parent.Text = tostring(character.Torso.Position) |
10 | end |

A simple function I found off of lua-users.org(http://lua-users.org/wiki/SimpleRound): It rounds given num down to numDecimalPlaces
01 | randomDecimalNumber = math.random(0,100)/3 |
02 | print(randomDecimalNumber) |
03 |
04 | function round(num, numDecimalPlaces) |
05 | local mult = 10^(numDecimalPlaces or 0) |
06 | return math.floor(num * mult + 0.5) / mult |
07 | end |
08 |
09 | print(round(randomDecimalNumber, 0)) |
10 | --29.666666666667 |
11 | --30 |
Here is how you would implement this function into your code:
01 | local player = game.Players.LocalPlayer |
02 | local character = player.Character |
03 |
04 | function round(num, numDecimalPlaces) |
05 | local mult = 10^(numDecimalPlaces or 0) |
06 | return math.floor(num * mult + 0.5) / mult |
07 | end |
08 |
09 | if not character or not character.Parent then |
10 | character = player.CharacterAdded:wait() |
11 | end |
12 |
13 | while wait(0.001) do |
14 | script.Parent.Text = |
15 | tostring(round(character.Torso.Position.x, 0)).." ,".. |
16 | tostring(round(character.Torso.Position.y, 0))..",".. |
17 | tostring(round(character.Torso.Position.z, 0)) |
18 | end |
I think it would be better in your case to use strong.format as you are using a string and may not need to round the number though you can if needed.
Much like patterns you include specifiers to indicate the location of the data and how it is formatted.
You would use the specifier %d since we only deal with integers.
A quick example (local script in StarterCharacterScripts):-
1 | local torso = script.Parent.Torso |
2 | local x, y, z |
3 |
4 | while wait(0.1) do |
5 | x, y, z = torso.CFrame:components() -- only use the position of the cframe |
6 | print(string.format('%d, %d, %d', x, y, z)) |
7 | end |
I hope this helps, please comment if you do not understand how / why this code works.
You can use math.floor or math.ceil
math.floor will round numbers DOWN whereas math.ceil will round numbers UP
For example:
1 | print(math.floor(1.293)) -- Output: 1 |
2 | print(math.ceil(1.293)) -- Output: 2 |
