Reforming my Question - How to spawn an Archetype ( PointLightMovable )

[ThePriest909]

Since my original question has been asnwered I should reform it:
How to spawn an Archetype ( PointLightMovable ).

Light Function is a const and there 's no way of setting it in UScript but this:

native final function SetLightProperties(optional float NewBrightness = Brightness, optional color NewLightColor = LightColor, optional LightFunction NewLightFunction = Function);

Any ideas about how I could possibly use the function and set a MatInst in a PointLightMovable in Uscript or any other functional way of doing it?
Using archrtypes doesn't work in my case for several reasons. I just need to set a single MatInst in my light class.

Thanks!

You can't change the Material a LightFunction is using. You can however change the lightfunction with that function. So you need to setup a lightfunction that uses your MatInst first.

This also covers the script side of LightFunctions.

Thanks for the link UE!

[ThePriest909]

So I tried the archetype way of doing the thing ( Link provided by UE above) however I have troubles spawning the archetype.
Any idea about what I'm doing wrong?

Here's what I tried:

/** spawn the !@^$#)#@!$^ dynamic light already */

var	Koukou_PowerLight		MuzzleFlashLight; //My PointLightMovable class
var	PointLightMovable		MuzzleFlashArchetype;

simulated function PostBeginPlay()
{
	//Weapon Light 
	MuzzleFlashLight = Spawn(class'Koukou_PowerLight',,,,, MuzzleFlashArchetype);
	SkeletalMeshComponent(Mesh).AttachComponentToSocket(MuzzleFlashLight.LightComponent,MuzzleFlashSocket);
	MuzzleFlashLight.LightComponent.SetEnabled(bIsShooting);

	super.PostBeginPlay();
}

defaultproperties
{
        MuzzleFlashSocket=MuzzleFlashSocket
        MuzzleFlashArchetype=PointLightMovable'01_Weapons.WP_Archetypes.Electric_Light_Arch'
}

The code compiles just fine but it won't spawn the archetype. At least that's what my log claims.

[UnrealEverything]

Would be helpful if you said what the log says.

Also you aren't following it exactly. I can't see where you spawn the LightFunction and assign it...

[ThePriest909]

Edit: Got an answer by the time I bumped this up so not bumping anymore...

I don't spawn the light function. i just spawn the light archetype where I assigned the light function according to the tut.



The archetype works fine when it's dropped in the editor or spawned by kismet I just can't spawn it in UScript for some reason.

[ThePriest909]

Here's the full script ( just testing version no debugging.. I removed the "if" stuff and logs but in any case all I did with the logs was if MuzzleFlashLight==none then type in log light couldn't spawn return and try again). I'm not a programmer so I really can't say if I"m right about this.

Light:

class Koukou_PowerLight extends PointLightMovable
    notplaceable;

var(Light) const archetype LightFunction LightFunctionArchetype;

function PostBeginPlay()
{
  local PointLightComponent PointLightComponent;
  local LightFunction LightFunction;

  Super.PostBeginPlay();

  PointLightComponent = PointLightComponent(LightComponent);
  if (PointLightComponent != None)
  {
    if (LightFunctionArchetype != None && LightComponent.Function == None)
    {
      LightFunction = new () LightFunctionArchetype.Class(LightFunctionArchetype);
      if (LightFunction != None)
      {
        LightComponent.SetLightProperties(,, LightFunction);
      }
    }

    PointLightComponent.UpdateColorAndBrightness();
  }
}
	
defaultproperties
{
    Begin Object name=PointLightComponent0
        LightColor=(R=150,G=180,B=255)
		Brightness=2.0
		Radius=256
		CastShadows=false
		
		//LightSgafts
		bRenderLightShafts=true
		OcclusionDepthRange=512
		
		BloomScale=2
		BloomThreshold=0
		BloomScreenBlendThreshold=0.5
		BloomTint=(R=255,G=255,B=255)
		RadialBlurPercent=100
		OcclusionMaskDarkness=0.25
    End Object
	
    bNoDelete=false
}

Weapon:

/** dynamic light */
var	Koukou_PowerLight		MuzzleFlashLight;
var	PointLightMovable		MuzzleFlashArchetype;
var repnotify bool bIsShooting;
var SkeletalMeshComponent SKMesh;

/*****************************************************************************************************************************************************
*/
simulated function PostBeginPlay()
{
	SKMesh = SkeletalMeshComponent(Mesh);
	
	//if (MuzzleFlashLight==none)
	{
		//Weapon Light 
		MuzzleFlashLight = Spawn(class'Koukou_PowerLight',,,,, MuzzleFlashArchetype);
		SkeletalMeshComponent(Mesh).AttachComponentToSocket(MuzzleFlashLight.LightComponent,MuzzleFlashSocket);
		MuzzleFlashLight.LightComponent.SetEnabled(bIsShooting);
	}
}

default properties
{
	MuzzleFlashArchetype=PointLightMovable'01_Weapons.WP_Archetypes.Electric_Light_Arch'
	bIsShooting=false
}

The bShoting thingy is used by Weapon's StartFire and StopFire Functions in order to switch the ligh while player is shooting. I don't use the usual MuzzleLight methods since it's not meant to be a "usual" weapon...
In any case the whole thing works fine if I spawn a usual light class. The problem came with the archetype light. I must be doing something wrong with spawning the archetype. I tried to use this:

[ThePriest909]

Spent the entire day on this... No luck.

I ended up with:

class Koukou_Weapon extends UDKWeapon
	dependson(Koukou_PlayerController)
	config(Weapon)
	abstract;

var	PointLightMovable					MuzzleFlashLight;
var()	const archetype	PointLightMovable	MuzzleFlashArchetype;

simulated function PostBeginPlay()
{
	SKMesh = SkeletalMeshComponent(Mesh);

	if (  SKMesh != none )
	{
		//Weapon Light
		MuzzleFlashLight = Spawn(MuzzleFlashArchetype.Class, None, 'None', Location, Rotation, MuzzleFlashArchetype);
		SkeletalMeshComponent(Mesh).AttachComponentToSocket(MuzzleFlashLight.LightComponent,MuzzleFlashSocket);
		MuzzleFlashLight.LightComponent.SetEnabled(bIsShooting);
	}
	
	if (MuzzleFlashLight == none)
    {        
		return;
    }
	super.PostBeginPlay();
}

default properties
{
	MuzzleFlashArchetype=PointLightMovable'01_Weapons.WP_Archetypes.Electric_Light_Arch'
	MuzzleFlashSocket=MuzzleFlashSocket
}

And a log warning saying

ScriptWarning: Accessed None 'MuzzleFlashLight'

Any info on how I could possibly spawn the Archetype would be most wellcome :\

[ThePriest909]

Bumping this up. All I'm asking is how to spawn a PointLightMovable Archetype.
Thanks.

[ThePriest909]

Shameless Bump!

[Farseer]

PointLightInstance = Spawn(class'PointLightMovable', self,, Location, Rotation, StaticMeshActor'SomeArchetypePackage.PointLightArchetype');

should work just as you have it in your example there, but make sure whatever you're trying to spawn is actually spawnable (bStatic=False, bNoDelete=False)

[ThePriest909]

Thanks Farseer! Haven't tried it yet but may I ask why a "StaticMeshActor"?

[Farseer]

My bad, sorry, should be PointLightMovable instead of StaticMeshActor there.

[ThePriest909]

Okay based on your example I tried a

MuzzleFlashLight = Spawn(Class'Koukou_PowerLight', self, , Location, Rotation, PointLightMovable'01_Weapons.WP_Archetypes.Electric_Light_Arch');

that get's me an error:

Error, Call to 'Spawn': bad or missing parameter 6

So I turned parameter 6 back into a variable and compliles just fine... can't really understand why it compiles that way to be honest :\ My var reads

var()	Archetype	PointLightMovable	MuzzleFlashArchetype;

However this won't work in game either. It gets me the same log error reading

ScriptWarning: Accessed None 'MuzzleFlashLight'

The light Class itself spawns just fine with a simple

MuzzleFlashLight=spawn(class'Koukou_PowerLight',self);
