Mission Cleanup / Pre Clean (Flowgraph Node)

Overview

• Node Name: Mission Cleanup
• Category: once_p_duration
• File: extensions/flowgraph/nodes/mission/preClean.lua
• Color: Mission blue (0.13, 0.3, 0.64, 0.75)

Cleans up the world state before a mission starts. Stashes vehicles and traffic, with optional overrides to keep the player vehicle or active traffic.

Internals

• Calls self.mgr.modules.mission:processVehicles(opts) with keepPlayer and keepTraffic options.
• Retrieves the original player ID via self.mgr.modules.mission:getOriginalPlayerId(), falling back to be:getPlayerVehicleID(0).

How It Works

1. The node runs once at the start of the mission duration.
2. Calls processVehicles on the mission module, which handles stashing the player vehicle, removing traffic vehicles, etc., based on the provided options.
3. Outputs the original player vehicle ID so downstream nodes can reference it (e.g., to restore it later via postClean).

Lua Code Example

-- Typical mission flowgraph setup:
-- preClean (keepPlayer = false, keepTraffic = false)
--   → vehId output feeds into spawn/setup nodes
--   → eventually postClean uses the same vehId to restore state

Key Dependencies

• self.mgr.modules.mission - processVehicles(), getOriginalPlayerId()
• be:getPlayerVehicleID(0) - fallback player vehicle lookup

Additional Methods

C:workOnce()

Called once when the node is triggered (flow-once execution).
