StateStack

Stack of values that allows multiple systems to enable or disable a state.

local disabledStack = maid:Add(StateStack.new(false, "boolean"))
print(disabledStack:GetState()) --> false

maid:GiveTask(disabledStack.Changed:Connect(function()
	print("From changed event we have state: ", disabledStack:GetState())
end))

local cancel = disabledStack:PushState(true) --> From changed event we have state: true
print(disabledStack:GetState()) --> true

cancel()  --> From changed event we have state: true
print(disabledStack:GetState()) --> false

disabledStack:Destroy()

Properties​

Changed​

</>
StateStack.Changed: Signal<T>

Fires with the new state

Functions​

new​

</>
StateStack.new(
defaultValue: any,--

The default value to use for the statestack.

checkType: string | nil
) → StateStack

Constructs a new StateStack.

GetCount​

</>
StateStack:GetCount() → number

Gets the count of the stack

GetState​

</>
StateStack:GetState() → T?

Gets the current state

Observe​

</>
StateStack:Observe() → Observable<T?>

Observes the current value of stack

ObserveBrio​

</>
StateStack:ObserveBrio(predicate: function) → Observable<T?>

Observes the current value of stack

PushState​

</>
StateStack:PushState(state: T?) → function--

Cleanup function to invoke

Pushes the current state onto the stack

PushBrio​

</>
StateStack:PushBrio(brio: Brio) → function--

Cleanup function

Pushes the brio's content onto the stack for the lifetime of the brio

Destroy​

</>
StateStack:Destroy() → ()

Cleans up the StateStack and sets the metatable to nil.

tip

Be sure to call this to clean up the state stack!
