Distance Between (Flowgraph Node)

Overview

• Node Name: Distance Between
• Category: repeat_instant
• File: extensions/flowgraph/nodes/util/distanceBetween.lua

Calculates the distance between two positions. Each position can be either a vec3 or a vehicle ID (number). Returns 0 as default when positions are invalid.

How It Works

1. getPosition() resolves each input: if it's a number, looks up the vehicle by ID and gets its position; if it's a vec3 table, converts it directly.
2. If a vehicle ID is invalid, returns vec3(0,0,0) as fallback.
3. Calculates posB:distance(posA) and outputs the result.

Usage Example

-- Distance between two vehicles:
-- posA = vehicleId1 (number)
-- posB = vehicleId2 (number)
-- → distance = vec3 distance between their positions

-- Distance between vehicle and point:
-- posA = vehicleId (number)
-- posB = {100, 200, 50} (vec3 table)

-- Distance between two points:
-- posA = {0, 0, 0}
-- posB = {100, 0, 0}
-- → distance = 100

-- Equivalent Lua:
local veh = getObjectByID(vehId)
local dist = veh:getPosition():distance(vec3(targetPos))

Key Dependencies

• getObjectByID() - resolves vehicle IDs to objects
• vec3:distance() - calculates 3D distance
