Retrieving the package name of an Actor

[Barbie]

How to get the package name an Actor is defined in?
Examples:
Actor 'Botpack.UT_Eightball' -> 'Botpack' is needed
Actor 'UnrealShare.DispersionPistol' -> 'UnrealShare' is needed

[MrLoathsome]

I think all you have to do is parse Actor.Self

*Or maybe Actor.Self.Class
** Or maybe Actor.Self.Class.Outer

Error, Unrecognized member 'self' in class 'Actor'

Do not bother for he who does not bother.

[MrLoathsome]

Whoops. I left off a bit, (.Class), as I was going by memory when I posted that. And was sort of posting pseudo-code.
(I thought you guys would figure that out.... )

Here is a tested example.

This line of code in a mutator actor class named SwarmSpawn.SS:

Code: Select all

	log(Self.Class);

Will result in this log line:

Code: Select all

ScriptLog: SwarmSpawn.SS

Code: Select all

Self.Class

You should be able to parse that somehow....

Unless I am not understanding your question completely.
In which case, ignore all of the above.

W.T.F. does that mean?

I have something but I'm not sure how well does it work from inside of an iterator (any) because simply STRINGS operations are like a doggy slow. Something in engine rejects such a "lag" crap. Look at GetItemName and do some modifications. Mutator calling that thing a single time return good results. If gets called from PawnList or Foreach looks garbled...
Look at a log operated by a small mutator + trying to retrieve package for a few monsters - looks nasty:

Code: Select all

ScriptLog: GetPackageOrigin::  for Behemoth3
ScriptLog: Behemoth3 belongs to package 
ScriptLog: GetPackageOrigin::  for Behemoth2
ScriptLog: Behemoth2 belongs to package 
ScriptLog: GetPackageOrigin::  for Behemoth1
ScriptLog: Behemoth1 belongs to package 
ScriptLog: GetPackageOrigin::  for Behemoth0
ScriptLog: Behemoth0 belongs to package 
ScriptLog: GetPackageOrigin:: UNREAL for Gasbag0
ScriptLog: Gasbag0 belongs to package UNREAL
ScriptLog: GetPackageOrigin:: LOGGER_A for Informer0
ScriptLog: Informer0 belongs to package LOGGER_A

The only good thing was Mutator itself, the rest is trash.
Aside, I was wonder why do you need that, I did not see many coders using craps slowing down servers. Like I said you have a "string" problem which is not a charm in UnrealEngine.
Gotta do more research... I'll be back.
Edit: See this - simply is garbled or I don't have a clue how to speed it up. Mutator responds well but not really the rest

Spoiler

class Informer expands mutator;

var DeathMatchPlus MyGame;
var bool Initialized;

function PostBeginPlay()
{

if (Initialized)
return;
Initialized = True;
Level.game.registerdamagemutator(Self);
Level.game.registermessagemutator(Self);
log ("A test mutator has been initiated...");
MyGame = DeathMatchPlus(Level.Game);
SetTimer(5,True);
}

function CallManure()
{
Local ScriptedPawn S;
Local Pawn P;
Local String Strg;
for ( P=Level.PawnList; P!=None; P=P.nextPawn )
{
if ( ScriptedPawn(P) != None && P.Health > 0 )
{
S=ScriptedPawn(P);
strg=GetPackageOrigin(S);
log(S.Name@"belongs to package"@strg);
}
}
strg=GetPackageOrigin(Self);
log (Self.Name@"belongs to package"@strg);
}

event Timer()
{
CallManure();
}

function String GetPackageOrigin(Actor AnActor)
{
Local string FullName, Temp;
Local int pos;

Temp="None";
if (AnActor == None) return Temp;
FullName="";
pos=0;
FullName=CAPS(AnActor.Class);
pos = InStr(FullName, ".");
StillMove:
if ( pos != -1 )
{
FullName = Left(FullName, Len(FullName) - pos - 1);
pos = InStr(FullName, ".");
Goto StillMove;
}
log ("GetPackageOrigin::"@FullName@"for"@AnActor.Name);
return FullName;
}

ENJOY

Not None-safe: (logs two warnings for None input, but returns correct value)

Code: Select all

function String GetPackageOrigin(Actor AnActor)
{
    return string(anActor.Class.Outer);
}

None-safe version:

Code: Select all

function String GetPackageOrigin(Actor anActor)
{
    if (anActor == None)
        return string(None);
    return string(anActor.Class.Outer);
}

This works because all objects have a class and classes are always directly located in a top-level package.

Small errata

Code: Select all

function String GetPackageOrigin(Actor AnActor)
{
	Local string FullName, Temp;
	Local int pos;

	Temp="None";
	if (AnActor == None) return Temp;
	FullName="";
	pos=-1;
	FullName=CAPS(AnActor.Class);
	log (FullName);
	pos = InStr(FullName, ".");
	log (pos);
	if ( InStr(FullName, ".") > 0 )
	{
		FullName=Left(FullName, InStr(FullName, "."));
	}
	log ("GetPackageOrigin::"@FullName@"for"@AnActor.Name);
	return FullName;
}

But I have to try other options of course.
But related to Wormbo's suggestion I think I got an idea for my MHReplacer...

Let me translate:
Don't bother helping someone who does not bother to understand. In this case barbie was joking, Higor knows that, therefore Higor is joking too.

I hope so. Otherwise my next reply to Higor was gonna get me kicked off the forum.

I like Wormbo's response better.

It extends my 2nd, more detailed post.

@Sektor. Nice job on re-inventing the ".Outer" wheel.
Exactly what I had in mind when I was suggesting parsing Actor.Class

In matters such as this, we should ALL just wait a bit to see what Wormbo has to say about it.

anActor.Class.Outer

That was it, thanks. I was already on the track with "Outer" but "anActor.Outer" returns the map name only.

Aside, I was wonder why do you need that

I want to replace some non stock items. Detecting if an item belongs to a class can usually be done by »ThisActor.IsA('WhatEver')« or »WhatEver(ThisActor) != None«, but then the server and the clients have to include the foreign package for all maps just to get rid of some items in a single map. So I decided to identify these items by their class name with »if (ThisActor.Class.Name == 'WhatEver')«. But what happens, if items of another package has the same class name? Then this method may detect wrong items and so I want to make sure that the item of interest belongs to the package XYZ:

Code: Select all

if (ThisActor.Class.Name == 'WhatEver' && String(ThisActor.Class.Outer) == "xyz")

(For example »MH-RiseOfDead[NoDaytime]« includes both »DC-Pawns2.u« and »DC-Pawns3.u« which have a lot of same-named classes.)

Like I said you have a "string" problem

Yep, the theory of everything isn't fully developed yet:

But seriously, I have no idea what you mean by this.

<EDIT>
added string typecasting to "ThisActor.Class.Outer"
</EDIT>

[sektor2111]

Because you can spy "Other.Class" if "left" from "string class" whatever letters match some evil creature just put it down... that is easy. Btw formula above I guess can save AttitudeToPlayer right ?

Now The Credit Section
Because you set me on a research I could figure some things today... that's another story off topic here... I have to rewrite a few things at my MH2 then...

@Sektor. Nice job on re-inventing the ".Outer" wheel.

If you check well the last one shown by me is able to get package-name even from current class ( mutator itself or whatever ) - credit goes at LoathSome (or Core ?) - stuff already done...

[Barbie]

Because you can spy "Other.Class"

Whoo, its even simpler then:

Code: Select all

if (String(A.class) == "PackageName.Classname")

[Wormbo]

See, that's why you state your root intent, not the problem you ran into while pursuing one particular approach of which you don't even know whether it will actually solve your problem.
