Signal

A signal is an object that provides a sort of event-driven behavior. When a signal is emitted, any nodes that are connected to the signal will be able to react.

---

Create

Create a new signal.

Sig: signal = Signal.Create() - Ret: Signal signal Newly created Signal

---

Emit

Emit the signal so that connected listeners can react.

Sig: Signal:Emit(args...) - Arg: args... Any number of arguments that will be passed to connected handler functions.

---

Connect

Connect a node to the signal. The function passed in should be a member function of the node's table. For instance:

function HealthBar:OnHealthChanged(newHp)
    self.quad:SetXRatio(newHp / Player.MaxHp)
end

function HealthBar:Start()
    GetPlayer().healthSignal:Connect(self, HealthBar.OnHealthChanged)
end

Sig: Signal:Connect(listener, func) - Arg: Node listener The node that will be notified when the signal is emit - Arg: function func The function on the node that will be invoked when the signal is emit

---

### Disconnect Sig: Signal:Disconnect(listener) - Arg: Node listener The node that will be disconnected from the signal
