Detecting if a table number value was changed

Help and Feedback Scripting Support

I am trying to detect if a value inside a table changes. What I tried was this but it didn’t work lol.

enemyTable.Health.Changed:Connect(function()
				newFolderForEnemy:SetAttribute("health", enemyTable.Health)
			end)

enemyTable looks something like this:

local enemyTable = {
Health = 100,
},

Is there any easy way of doing so?

You could use __newindex, but that requires a metatable however

How could something like this look? An example would be nice :>

Hi! Try to do this idk:

local enemyTable = {
Health = Instance.new("NumberValue")
}
enemyTable.Health.Value = 100

enemyTable.Health.Changed:Connect(function(new)
newFolderForEnemy:SetAttribute("health", new)
end)

Yes that’s a way but my system sadly requires it to be a value inside a table. No instance

hmm, try to do this:

local enemyTable = {Health = {Old = 100, New = 100}}
game["Run Service"].RenderStepped:Connect(function()
	if enemyTable.Health.Old ~= enemyTable.Health.New then
		enemyTable.Health.Old = enemyTable.Health.New
newFolderForEnemy:SetAttribute("health", enemyTable.Health.New
)
	end
end)
wait(1)
enemyTable.Health.New = 90

I think something like this

local Enemy = {}
local EnemyTable = {
	Health = 100,
	__newindex = function(self, index, value)
		print("Table changed: " .. index .. " = " .. tostring(value)) -- just a test
		rawset(self, index, value)
	end
}

local Monster = setmetatable(Enemy, EnemyTable)

Monster.Health = 5 -- just a test
