Hi, I recently tried to make a temporary effect for a mod using the BeamEmitter class. I made a death prevention ability for one of my player classes, so when the player dies, he disappears, an effect is spawned ( a beam shooting towards the sky ), and after 5 seconds the player respawns at the location he died. I tried to use the BeamEmitter for this ( I made a subclass called ReviveEffect with bNoDelete false so it can be spawned ), but whenever I spawn the emitter during gameplay ( the script spawns it ), the game crashes. Is this a bug, or are these emitters only for mapmaking? ( can't be spawned during gameplay )

This is the error I get: i52.tinypic.com/nqo29i.jpg

EDIT: I use the 227h patch

This is the ReviveEffect class:

Code (C++):

//=============================================================================
// ReviveEffect.
//=============================================================================
class ReviveEffect2 expands BeamEmitter;

defaultproperties
{
  bNoDelete=false
  LifeSpan=7.0
  BoxVelocity=(Z=(Min=500,Max=500))
  ParticleTextures(0)=Texture'GenWarp.Sun128a'
}
 

This is the effect class that makes the player "fade out" smoothly and spawns the beam effect:

Code (C++):

//=============================================================================
// ReviveEffect.
//=============================================================================
class ReviveEffect expands Effects;

var ReviveEffect2 Effect;

simulated function PostBeginPlay()
{
  Super.PostBeginPlay();
 
  if(Owner == None)
  {
    Destroy();
    return;
  }

  Mesh = Owner.Mesh;
  //Animframe = Owner.Animframe;
  //Animsequence = Owner.Animsequence;
  Velocity = 900 * Normal(Owner.Velocity);
 
  Effect = Spawn(class'ReviveEffect2',,,self.Location,self.Rotation);

  if ( Level.bDropDetail )
  {
    LightType = LT_None;
    LifeSpan *= 0.7;
  }
}

auto state Explode
{
  simulated function Tick(float DeltaTime)
  {
    if ( Level.NetMode == NM_DedicatedServer )
    {
      Disable('Tick');
      return;
    }
   
    ScaleGlow = Lifespan;
    DrawScale = 0.1 + 0.2 * (Scaleglow);
    LightBrightness = (ScaleGlow) * 210.0;
    if ( LifeSpan < 0.3 )
      SetPhysics(PHYS_Projectile);
  }
}



defaultproperties
{
  LifeSpan=1.0
  bParticles=true
  DrawScale=0.6
  DrawType=DT_Mesh
  Style=STY_Translucent
  Texture=Texture'CustomTexture.Effects.ReviveEffect'
  LightBrightness=255
  LightHue=170
  LightSaturation=96
  LightEffect=LE_NonIncidence
  LightRadius=6
  LightType=LT_Pulse
} 

The error pops out as soon as the emitter class is spawned...

Seams you are missing texture package load line, which may cause ParticleTexture to be None in game:
Code:

//=============================================================================
// ReviveEffect.
//=============================================================================
class ReviveEffect2 expands BeamEmitter;

#exec obj load file="GenWarp.utx"

defaultproperties
{
  bNoDelete=false
  LifeSpan=7.0
  BoxVelocity=(Z=(Min=500,Max=500))
  ParticleTextures(0)=Texture'GenWarp.Sun128a'
} 

On other regards I'd like to point out to easily make some nifty looking particle effects that's going to be used on mods. Simply:
- Create the particle effect in editor and when you are done:
- Select emitter actor and press Ctrl+C
- Bring up your UC file for the particle FX and paste text in defaultproperties block
- Remove Begin/End actor/map garbage aswell as Location/bDynamicLight lines which are not needed.
