Why does one repeat loop work and the other doesn't?
Why does this work...
repeat
script.Parent.Reflectance = script.Parent.Reflectance+0.1
wait(0.2)
until script.Parent.Reflectance == 1
and this one doesn't?
local a = script.Parent.Reflectance
repeat
a = a+0.1
wait(0.2)
until a == 1
Wanted to clear up my curiosity.

It has to do with adding decimals in Lua. If you add a whole number to a on line 4, and divide by 10, it should fix the problem. User#11440 120 — 8y

Here's a question that was asked awhile ago that relates to your probelm https://scriptinghelpers.org/questions/29524/trouble-with-numeric-for-loop-and-step-variant User#11440 120 — 8y

So instead of "+0.1" you are saying that I should replace it with "+(1/10)"? RAYAN1565 691 — 8y

Yeah. This hasn't been tested, but that would be the first thing I would test. User#11440 120 — 8y

Problem
Declaring the variable "a" in the second loop is saving the object's reflectance as a number - it is not holding a reference to the reflectance property.
When is it appropriate to declare a variable then?
Instead of just creating a variable that holds a number, and changing that number (which evidently will not update the property), you should create one referencing the object you're trying to change - to shorten your code and make it look nicer. Here's an example:
-- You should also make your variable names memorable, instead of just using random characters.
local parent = script.Parent
repeat wait(0.1)
parent.Reflectance = parent.Reflectance + 0.1
until parent.Reflectance >= 1
This same logic applies with anything else you're trying to change. You want to create a reference to another reference - not it's value if you are to change it.

Very well answer and explanation. Does this also apply to other loops? RAYAN1565 691 — 8y
