### From Unreal Wiki, The Unreal Engine Documentation Site

UT2003 :: Actor >> IonCannon (Package: XWeapons)

Satellite that floats in the air above a level and generates an ion blast when triggered by PainterFire.

All IonCannons in a map form a linked list with the first ion cannon's `bFirstCannon` property set to `True` and `nextCannon` pointing to the next ion connon. This list is used by the Ion Painter gun to quickly find a cannon that can attack the specified location.

## Properties

### Main

int Damage
  per wave
float DamageRadius
  of final wave
class<DamageType> DamageType
Sound FireSound
class<IonEffect> IonEffectClass
Vector MarkLocation
float MaxAngle
  The maximum angle the cannon may deviate from pointing straight down when firing. The default value is 45, and this is a fine example of Digital Extremes not RTFM. UnrealScript trig Global Functions are in Wikipedia:Radians, so 45 actually means about 7 degrees. Which is why default cannons won't fire very far from the spot beneath them. If you want 45 degrees, use 0.785.
float MaxRange
  default 10,000
float MinRange
  default 1,000
float MomentumTransfer
  per wave
vector ShakeOffsetMag
  max view offset vertically
vector ShakeOffsetRate
  how fast to offset view vertically
float ShakeOffsetTime
  how much time to offset view
vector ShakeRotMag
  how far to rot view
vector ShakeRotRate
  how fast to rot view
float ShakeRotTime
  how much time to rot the instigator's view

## Triggerable?

It's not possible to use a trigger or a zone to activate the Ion Cannon when a player encroaches the trigger radius. But it would be possible to create an "IonCannonTrigger" or a custom volume which upon triggering selects an ion cannon and makes it fire at a specified actor or the event instigator.

There is a custom class at Anozireth/IonTrigger. You can either tell it to fire at a specified target or simply at the player who triggered it. You can set the minimum delay between firings, and you can set a maximum number of firings.
