UE2:TeamVehicleFactory

SVehicleFactory >> Actor >> TeamVehicleFactory (custom)

This custom actor really duplicates much of the functionality of the ONSVehicleFactory subclasses, but the big feature is that nearly any vehicle class can be spawned. Although this actor cannot display the selected vehicle class in the editor, it does offer added controls that mappers for VCTF or other vehicle gametypes might want.

Features

• The ability to spawn random vehicles from a list of vehicle classes
• The ability to spawn nearly any vehicle class in gametypes that allow vehicles
• The ability to trigger PreSpawn and (Post)Spawn events
• The option to allow the vehicle to spawn over and crush other actors
• The option to use this as either a triggerable or an automatic (timed) vehicle factory.
• Greater control over spawn timing

Notes

• If you use a TeamVehicleFactory "as is" in your custom map, please credit me in the readme file of the map. (SuperApe)
• You have to supply spawning effects and sounds, via ScriptedTrigger, Emitter and the like. This is meant to allow flexibilty in the ways you want vehicles to spawn. An example VCTF map posted on this UP Forum thread gives my suggestion for spawning particles and sound. (It appears similar to pickup spawning.)
• With bAutoSpawn on and without a PreSpawnTime of around 2 seconds, you run the risk of spawning a vehicle before headlights can be properly spawned at map start. Subsequent vehicles after map start will spawn headlights normally.
• Turrets that are spawned automatically get an AIController. They are auto turrets; firing at enemies, or if set to neutral (team 255), firing at any non-neutral controlled pawn it detects.
• The AS Spacefighters are spawned with a minimum velocity that makes them impractical to use. However, a custom launcher for these is easy to make with a TryToDrive() function.
• This has a slightly larger bBlocked check radius than ONSVehicleFactory. ( 1.33 : 1.25 )

Properties

Main

int TeamNum

Team Number to be set on spawn. 0= red, 1= blue, 255= neutral / none

bool bPlayerControl

Only player instigators can trigger.

bool bAutoSpawn

Will spawn at regular intervals. The triggering ability is disabled.

int RespawnTime

Interval to wait before AutoSpawning.

name PreSpawnEvent

Event to trigger before spawn.

int PreSpawnTime

Time before spawn to trigger event. Will begin event this many seconds before the factory is set to AutoSpawn.

name SpawnEvent

Event to trigger after spawn. A post spawn event.

bool bCrushable

Allow spawning over colliding actors. Note: Turrets will normally spawn in collision with other actors, spawned vehicles will generally move out of the way.

int RetrySpawnTime

Interval to wait if bBlocked.

bool bRandomFlip

Neutral vehicles may face backwards.

bool bRandomSpawn

Will spawn random vehicle class.

struct class<Vehicle> SpawnedVehicle

Selected random vehicle class.

array<SpawnedVehicle> RandomVehicles

List for random vehicle spawn.

Hidden

bool bWaiting

Waiting to spawn.

int FactoryTime

Time last spawn. (in Level.TimeSeconds)

bool bPreSpawn

Should trigger PreSpawnEvent next.
