Check when table value is changed

I simply want to be able to check when an index in a table is changed.

To put in context, I have a table in a module script that when changed I want to replicate to all clients by firing a remote event.

Depending on how are you planning to update the values, that’s where you can fire an event inside the updating logic.

I know that is a way to do it but it doesn’t answer the question. I am changing it from multiple locations so doing this would be a bit of a pain.

My suggestion is that you can just create a function in your module script that handles the updating logic, stated in this post of a similar problem as yours.

.Changed() for tables?

Some of the replies here suggest using metatables. This is not the best solution for you. In your case, remember that the only time that the XP value in the table will change is when you change it from somewhere in your codebase. This means that you can avoid all of the complicated, unreadable, and messy metatable code. Instead, you should create a function that is used for setting/updating values in CharData. That function can then trigger any code that you want to respond to XP changes, for e…

You could even make it a method of the table to save work.

local data = {} -- data goes in the table

data.Set = function(self, key, value)
    self[key] = value
    -- fire all clients
end

return data

data:Set("nextMode", "FreeForAll")
