Create Ultrasonic Sensor (Flowgraph Node)

Overview

• Node Name: Create Ultrasonic Sensor
• Category: once_instant
• File: extensions/flowgraph/nodes/tech/setupUltrasonicSensor.lua

Sets up an ultrasonic sensor on a vehicle and returns its ID.

Pin Schema

Input Pins

Output Pins

Behavior

• workOnce() - Creates an ultrasonic sensor on the specified vehicle (or player vehicle if vehId is nil). Passes width/height as a size array. Returns the sensor ID.

How It Works

1. Place this node and connect a vehicle ID (or leave blank for the player vehicle).
2. Optionally set width and height dimensions.
3. On first execution, creates the sensor and outputs its ID.
4. Use the sensorId output with getUltrasonicReadings to poll data.

-- Internal call:
local vehId = self.pinIn.vehId.value or be:getPlayerVehicleID(0)
local args = {
  size = { width or 50, height or 50 }
}
local sensorId = extensions.tech_sensors.createUltrasonic(vehId, args)

Key Dependencies

• extensions.tech_sensors.createUltrasonic() - Creates the sensor
• be:getPlayerVehicleID(0) - Fallback vehicle ID

Additional Methods

C:init()

Initializes the node, setting up pins and default properties.
