✅ Verified in-game — deeper pass: confirmed this is a thin 12-line subclass of MrxSupportDelivery -- only override is a flare designator with AA test "none"; replaced vacuous "ensure Create is called" notes with the real inherited-behavior + cross-links, and documented the SetCargo-from-caller-prototype pattern

MrxBoatDelivery

Module: mrxboatdelivery.lua

Overview

MrxBoatDelivery is the water-drop variant of the standard helicopter cargo delivery. It’s a very thin subclass of MrxSupportDelivery — the entire file is one Create function. All the real work (spawn cargo, spawn heli, winch, fly to target, drop) is inherited from MrxSupportDelivery; the only thing this module changes is swapping the smoke designator for a flare designator with anti-air testing disabled, which suits a marker dropped over open water. MrxSupportData uses it for every Boat-type catalog item (jetskis, speedboats, the PMC patrol boat, etc.).

The inherit("MrxSupportDesignatorFlare") line is effectively unused: Create creates the flare designator explicitly via MrxSupportDesignatorFlare:Create(), it doesn’t inherit designator methods. Behaviorally this is a MrxSupportDelivery with a flare designator bolted on.

Inheritance

• Inherits from: MrxSupportDelivery, MrxSupportDesignatorFlare
• Imports: none

Instance pattern

Same class-factory pattern as MrxSupportDelivery/MrxSupportDesignatorFlare, not per-uGuid — Create(oSelf, uOwnerGuid) builds a new table via setmetatable/__index, exactly like its parents. No OnActivate/Awake, no tInstance registry. It tracks the following key fields:

• sCargoToDeliver: The type of cargo to be delivered.
• oDesignator: The designator used for marking the drop zone.

Functions

Create(oSelf, uOwnerGuid)

The only function in the file. Calls MrxSupportDelivery:Create(uOwnerGuid) to build the base delivery object, then: copies the caller-prototype’s sCargoToDeliver via SetCargo(oSelf.sCargoToDeliver), sets the module name to "MrxBoatDelivery", creates a MrxSupportDesignatorFlare with SetAATestLevel("none"), and installs it as the designator (replacing the blue-smoke one the parent Create set up). Returns the new support object.

oSelf.sCargoToDeliver reads the cargo name off the prototype table the catalog set up (e.g. oSupport:SetCargo({"Dinghy", ...}) in MrxSupportData), and SetCargo here copies it onto the freshly built instance. That’s why the boat items in the catalog configure cargo on the object before it ever runs — the value is read back out at Create time.

Events

None of its own — every event subscription (Event.ObjectHibernation for the heli/cargo wake, and Event.ObjectWinched for the drop) comes from MrxSupportDelivery’s _DesignatorCallback → _DeployWinch → _WaitCallback → CargoDropped chain. See that page for the full delivery sequence.

Notes for modders

• What to change lives on the parent, not here. Drop height, the delivery helicopter template, cargo picking, and the actual winch sequence are all on MrxSupportDelivery — this file only chooses a flare designator with AA disabled.
• Cargo is set by the caller’s prototype. The catalog ([MrxSupportData](mrxsupportdata)) sets SetCargo(...) and SetCareless(true) on the prototype; Create copies the cargo across. To change what a boat item delivers, change the catalog entry’s cargo (or set sCargoToDeliver on the prototype before Create), not a field on the returned instance.
• Flare vs. smoke over water: the flare designator + SetAATestLevel("none") is the water-specific choice. If you clone this for a land drop you’d typically want smoke and a ground-drop-zone validation function instead — see MrxCrateDelivery for that shape.
