MrxTankBuster

Module: mrxtankbuster.lua

Overview

MrxTankBuster is a smoke-designated anti-armor strike: the player pops red smoke, a jet flies in and fires a guided AT missile at every non-PMC tank within range. It inherits from MrxSupport and designates with MrxSupportDesignatorSmoke.

Inheritance

• Inherits from: MrxSupport
• Imports: MrxSupportDesignatorSmoke

Instance pattern

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

• uOwner: The GUID of the player who owns this support.
• uJet: The GUID of the aircraft performing the airstrike.
• uDeliveryVehicle: The vehicle used to deliver the ordnance.
• oDesignator: The designator object for guiding the strike.

Functions

Create(self, uPlayerGuid)

Builds the instance. Creates a MrxSupportDesignatorSmoke, sets smoke color "red", AA test level "basic", and clears its validation function (SetValidationFunction(nil) — no drop-zone check). Recruit "Pilot", module name "MrxTankBuster".

DesignationCallback(self)

Runs on smoke-designation complete. Flies the delivery jet in with Airstrike.Flyby (spawn/target points from the camera, speed 120, callback Strike, jet in self.uJet), then schedules a Misha freeplay-support VO 3 seconds later via Event.TimerRelative → MrxSupport.PlayAirstrikeVO.

Strike(self)

Runs when the jet arrives. Pg.FastCollectTanks within 200 units of the player, then for each tank that either has no driver or whose driver is not labeled “PMC”, schedules LaunchMissile with Event.TimerRelative staggered 0.2 * nCount seconds apart.

LaunchMissile(self, uTarget)

Launches one homing "Airstrike AT Missile" from the jet at uTarget via Airstrike.SpawnTargettedOrdnance (speed scale 30, "impact", callback Object.Kill on the target). Then blips the missile red on the radar via BlipAircraft (inherited from MrxSupport).

_ValidateDropZone(fCallback, nX, nY, nZ, oSupport)

Drop-zone validator wrapping Ai.TestDropZone. Note: this one is defined but not wired up — Create explicitly passes SetValidationFunction(nil), so the smoke designator never calls it. Present as a spare/override hook.

Events

No event subscriptions. DesignationCallback is the smoke designator’s completion callback (via MrxSupport:Commence), Strike is the flyby-arrival callback, and LaunchMissile / the VO are fired by Event.TimerRelative timers — none are Event.Create subscriptions.

Module constants & tunables

All inline (no module-level locals):

• Payload: "Airstrike AT Missile" (homing), nSpeedScale = 30, callback Object.Kill (guaranteed one-shot kill on hit).
• Target search: Pg.FastCollectTanks, radius 200 units, non-PMC only, 0.2s between launches.
• Designator: red smoke, AA level "basic", no validation.
• Jet flyby speed: 120; recruit "Pilot".

Notes for modders

• The kill is deterministic: the missile’s impact callback is Object.Kill(uTarget), so any tank hit dies regardless of missile damage. Change that callback in LaunchMissile (a plain global) if you want normal damage instead.
• Targeting is tank-only and non-PMC-only. Swap Pg.FastCollectTanks or drop the PMC-label check in Strike to broaden it.
• _ValidateDropZone exists but is disabled by SetValidationFunction(nil); pass it (or your own) to SetValidationFunction if you want the smoke to require a clear drop zone.
