Detect Value Change


This is a simple method for "watching" a data value in the skin (variable, measure or option) and taking action when the value changes.

function Initialize()
Old = nil
-- If the "Old" value starts as nil, the change action will always fire on the first update.
end
function Update()
local New = SKIN:GetVariable('SomeVariable')
-- or
local New = SKIN:GetMeasure('SomeMeasure'):GetValue()
-- or
local New = SELF:GetOption('SomeOption')
if Old ~= New then
-- do stuff
Old = New
end
end
