How do you use a :changed() function on an in-script variable?
So this is what I want to achieve in a sense...
lol = 0 -- my variable lol.Changed:connect(function() end) -- might not be this, but something like this where it detects if it changes
0
0

You could achieve this in multiple ways.
The simplest way would be to call a function that is in control of changing the variable. Then, within that function, you could include the code that you want to run when the variable changes.
local lol = 0
local ChangeLol = function(NewVal)
print("lol has changed")
lol = NewVal
end
So, whenever you want to change the value of 'lol', you would call the ChangeLol function. For example to add 1 to its current value, you would go:
ChangeLol(lol + 1) --> "lol has changed"
Another way of doing this would be to use metatables. You can detect when a value within a table is changed, and do something when that occurs. For example:
local lol = setmetatable({Value = 0},{
__newindex = function(self,index,value)
print("lol has changed")
rawset(self,index,value)
end;
})
Then, if you wanted to add 1 to the value of 'lol', you could go:
lol.Value = lol.Value + 1 --> "lol has changed"
which would also print that the value changes. You would then run the desired code inside the __newindex function.
Hope this helps!
