is it even possible?..

to create an actor/object that will persist from level change to keep some information on travel, specifically stored variables such as bools, strings etc. Just wanted to ask here before I bust out the c++ compiler and do some read/write file input/output with the headers.

[.:..:]

Yes! there is 1 way which works based on a hack and it works both on dedicated server and single player mode.

First do this:
Create a new class under 'Console' (in here called class 'StaticData').
On some actor (or object) set the Engine default console class to that (example: Class'Engine'.Default.Console = Class'StaticData') to force engine to keep the information about the class so it dosent get garbage collected.
add variables to 'StaticData' class what you wish to store information about, I.E:

Code: Select all

Class StaticData extends Console;

var MyMapData MapObject;
var bool bBooleanA;

Then fill in the variables:

Code: Select all

Class'StaticData'.Default.MapObject = New(None) Class'MyMapData';
Class'StaticData'.Default.bBooleanA = True;

And so you can read the data after mapchange:

Code: Select all

Log(Class'StaticData'.Default.MapObject@Class'StaticData'.Default.bBooleanA)

Which would give some output like:

Code: Select all

ScriptLog: Transient.MyMapData0 True

Hope this made any sense at all.

[.:..:]

So a practical example would be:

Code: Select all

Class ActorCounter extends Actor;

var MyMapData MyData;

function PostBeginPlay()
{
      local Actor A;

      if( Class'Engine'.Default.Console==Class'StaticData' )
      {
            MyData = Class'StaticData'.Default.MapData;
            Log("Found old data:"@MyData@MyData.ActorCount);
      }
      else
      {
            Log("Generating new data");
            MyData = New(None) Class'MyMapData';
            ForEach AllActors(Class'Actor',A)
                  MyData.ActorCount++;
            Class'StaticData'.Default.MapData = MyData;
            Class'Engine'.Default.Console = Class'StaticData';
            Log("Counted map actors to"@MyData.ActorCount);
      }
}

Code: Select all

Class MyMapData extends Object;

var int ActorCount;

Code: Select all

Class StaticData extends Console;

var MyMapData MapData;

And summon ActorCounter in 2 maps and you see the output will be on second map something like
"ScriptLog: Found old data: Transient.MyMapData0 2734"

I found another way before Dots posted, it uses an Object and config(myconfig) with variables flagged as Config, and it saves them using saveconfig();

It works for what I want to do, but i may switch to the method dots has depending if i require it in the long run.

Hmm. I see that it'd work for data storage, but is there anyway to call functions using that method, dots? A while back I had tried to make a better chatlog for ICD but gave up after I realized that I had to make a new file for every map because the statlogfile automatically closes on map change and you can't re-open a file in UScript (and I can't figure out native code. Casey don't tell me you finally got it and didn't tell me...).

I gave up because i couldn't get it to work with 225 at all due to no 225 headers, but hopefully we can get some 227 headers so i wont be discouraged.
