Vehicle Touch

Overview

• Node Name: Vehicle Touch
• Category: repeat_instant
• File: extensions/flowgraph/nodes/vehicle/touching.lua

Checks if a vehicle is colliding with another vehicle. If no second ID is given, checks for any vehicle-to-vehicle collision and reports up to 5 colliding vehicle IDs.

Key Methods

How It Works

1. Looks up vehicle A in map.objects and reads its objectCollisions table.
2. Specific check: If vehIdB is provided, checks if that ID exists in the collision table.
3. Any check: If no vehIdB, collects all colliding IDs, sorts them, and outputs up to 5.
4. Sets touching flow and touchingb bool if any collision is found.

Usage Example

-- Flowgraph:
-- [Player Vehicle] → vehIdA → [Vehicle Touch] → touching → [Penalty Logic]
--                                    ↓ vehId1
--                               [Log Collision Partner]

-- Check collision in GE Lua:
local cols = map.objects[myVehId].objectCollisions
for otherId, _ in pairs(cols) do
  print("Touching vehicle: " .. otherId)
end

Key Dependencies

• map.objects[id].objectCollisions - per-vehicle collision table maintained by the map system
