SSE Papyrys Help Please

[fishburger67]

In Oldrim, if I added a new Property to a script on a quest, I could get the script to load the new property like this:

 

Scriptname test extends SKI_ConfigBase

      .....

       test2.reset()

        test2.stop()
        Utility.wait(0.5)
       test2.start()    ;Reload all new variables and aliases

       .......

 

Scriptname test2 extends Quest

 

GlobalVariable Property aGlobal Auto

 

function setAGlobal(int value)

  aGlobal.setValue(val)

endFunction

 

int function getAGlobal()

  return aGlobal.getValue()

endFunction

 

 

In the above code, test.psc is calling reset, stop and start on test2.psc.  The purpose is to have the newly added Property "aGlobal" get loaded properly .   This is assuming that we are loading a save game that originally did not have test2.aGlobal.

 

This all used to work just fine in OldRim, but in SSE, I am getting errors like

 

"ERROR: Cannot call GetValue() on a None object, aborting function call"  if I call getAGlobal();

 

If I start a brand new game, it all works fine.  It is only a problem when I am testing a save game where the code did not have the new Property.a

 

Anyone have an idea how to do this ?

 

I know reset, start, and stop are being called because I have some trace code that is writing to the log file.

The new properties form likely isn't getting set. An easy fix would be to add a quick fill check like this:

 

Scriptname test2 extends Quest

GlobalVariable Property aGlobal Auto

function setAGlobal(int value)
	if !aGlobal
		aGlobal = Game.GetFormFromFile(0x???, "???.esp") as GlobalVariable
	endIf
	aGlobal.setValue(val)
endFunction

 

int function getAGlobal()
	if !aGlobal
		aGlobal = Game.GetFormFromFile(0x???, "???.esp") as GlobalVariable
	endIf
	return aGlobal.getValue()
endFunction

Alternatively, you could use some sort of update procedure that simply uses GetFormFromFile to set the property to the desired value. This way it will only execute once when you update and you don't have go through an if statement every time you want to access the property.

	endIf
	return aGlobal.getValue()
endFunction

 

 

Turns out that the property did not get set because I added the property to the script, started a game and saved,  but forgot to actually add the global value to the esp.  Starting a new game had the property set correctly after the global was added.

 

Thanks so much for this.

 

I will use this technique in the future.
