Find out how much a value has changed? [ :Changed() ]
How can I find out how much a value has changed? Here is my script:
game.Players.PlayerAdded:Connect(function(player)
local leaderstats = Instance.new("Folder")
leaderstats.Parent = player
leaderstats.Name = "leaderstats"
local points = Instance.new("IntValue")
points.Parent = leaderstats
points.Name = "Points"
oldValue = player.leaderstats.Points.Value
player.leaderstats.Points.Changed:Connect(function(newValue)
local pointsChanged = newValue - oldValue
print(pointsChanged)
end)
end)
This onlly gives me the value.... Not how much it has changed from the old value...

You never update the oldValue which is probably 0 so it will not change the new value.
Secondly you have cariables for the IntValue so use them.
Lastly oldValue should also be a local variable.
Example
-- you should use get service where possible
-- incase the name if the service is changed
game:GetService("Players").PlayerAdded:Connect(function(plr)
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
local points = Instance.new("IntValue")
points.Name = "Points"
points.Parent = leaderstats
local oldValue = points.Value -- use the variable
points.Changed:Connect(function(newVal)
print(newValue - oldValue)
oldValue = newValue -- update the old value variable
end)
-- parent to the game last
leaderstats.Parent = plr
end)
I hope this helps.
