Wait (Flowgraph Node)

Overview

• Node Name: Wait
• Category: logic
• Behaviour: {duration = true, once = true}
• File: extensions/flowgraph/nodes/logic/wait.lua

Delays flow by a specified time duration. Once flow arrives, waits the configured number of seconds before passing flow through. Requires constant flow input.

Pin Schema

Input Pins

Output Pins

Behavior

• init(mgr, ...) - Resets timer to 0, not running.
• _executionStarted() - Resets timer and running state.
• work(args) - Clears impulse output. When flow starts and timer hasn't completed, begins timing. Reset pin clears the timer. Each frame, increments timer by dt (real or sim). When timer exceeds duration, outputs flow and fires the one-shot impulse.
• updateTimer() - Adds dt to timer; when timer >= duration, stops running and fires impulse.
• drawMiddle() - Shows a progress bar and reset button.

How It Works

The node starts timing when flow first arrives. It uses either real time (dtReal) or simulation time (dtSim) based on the useDtSim flag. Once the timer reaches the configured duration:

• The flow output becomes active (stays active as long as input flow continues)
• The impulse output fires once

The timer does not auto-reset - once complete, flow passes through continuously. Use the reset pin to restart the wait cycle.

Example Usage

-- Wait 5 seconds before showing a UI element:
-- duration = 5
-- flow → [Wait] → impulse → [Show UI]

-- Using simulation time (pauses when game pauses):
-- useDtSim = true
-- duration = 10
-- Waits 10 seconds of in-game time

Additional Methods

C:_onDeserialized(res)

Called after the node is deserialized (loaded from file). Restores runtime state from saved data.

Parameters:

• res
