Efficient time value?
Hi guys! I am trying to save a "Time" value with Datastore and then compare it to another number when they join the game again.
Basically, it is in the this format Hours:Minutes:Seconds:Milliseconds
However, I have a problem - I can convert this to a number without the ":" and compare it to the new number when they join the game as it is a NumberValue, but to display it to the player, I want to put the ":" back in - what is the easiest way to do it? :) Thanks!

Two options:
1.
Make individual values for each time segment and change the time with a script.
local hours = script.Hours local minutes = script.Minutes -- etc.
2.
Use string manipulation to get the number (value has to be a string). NOTE: The string does not have any ':' in it, they will be added in the script.
local val = script.Time local hours = string.sub(val.Value,1,2) local minutes = string.sub(val.Value,3,4) local seconds = string.sub(val.Value,5,6) local mseconds = string.sub(val.Value,7,8) print(hours.. ":" ..minutes.. ":" ..seconds.. ":" ..mseconds)
The only problem is that changing the numbers may be problematic, so you can have another script that changes the time through a similar method with variables:
local hour = 00 local minute = 05 local second = 12 local msecond = 54 script.Time.Value = hour.. "" ..minute.. "" ..second.. "" ..msecond
:) Hope I helped.

Though TheDeadlyPanther's suggestion is easiest, you can do the following (this is possibly what adark meant) - combining all the components into a single number:
--Saving time = milliseconds + seconds * 1000 + minutes * 1000 * 60 + hours * 1000 * 60 * 60 --Loading hours = math.floor(time / (1000 * 60 * 60)) time = time % (1000 * 60 * 60) minutes = math.floor(time / (1000 * 60)) time = time % (1000 * 60) seconds = math.floor(time / 1000) time = time % 1000 milliseconds = time
Another option (which you can combine with the others) is to use the full range of valid datastore characters to encode your number(s). You can use string.char(1) through string.char(128) -- that's 127 possibilities per digit, which is a lot more than the 10 per digit you get by just using numbers! Unfortunately, you need to do complicated math to encode and decode a number to use that 127 possibilities, but it is possible.
