State

function State(initialValue: any?): State

Constructs and returns a new state object, with an optional initial value.

Parameters

  • initialValue: any? - the value which should initially be stored in the state object.

Object Methods

get()

function State:get(): any
Returns the currently stored value of this state object.

If dependencies are currently being detected (e.g. inside a computed callback), then this state object will be used as a dependency.

set()

function State:set(newValue: any, force: boolean?)
Sets the new value of this state object.

If the new and old values differ, this will update any other objects using this state object. However, if they're the same, no update will be performed.

Force updating

If you want to override this behaviour, you can set force to true. This will ensure updates are always performed, even if the new and old values are the same (as measured by the == operator). This is most useful when working with mutable tables.

However, be very careful with this, and only force updates when you need to for performance reasons. Try a solution involving immutable tables first. Abuse of force updating can lead to suboptimal code that updates redundantly.

Example Usage

local numCoins = State(50)

print(numCoins:get()) --> 50

numCoins:set(25)
print(numCoins:get()) --> 25

numCoins.onChange:Connect(function()
    print("Coins changed to:", numCoins:get())
end)
