How does this code work?

[gooser]

I was just looking over Jaxonz latest "Diagnostics" mod and I ran across these lines in the MCM script:

bool bValidateSKSE = true
state optValidateSKSE
	event OnSelectST()
		bValidateSKSE = !bValidateSKSE
		SetToggleOptionValueST(bValidateSKSE)
		((Self as Quest) as JaxonzDiagnosticsQuest).bValidateSKSE = bValidateSKSE
	endEvent

	event OnHighlightST()
		 SetInfoText("When selected, Jaxonz Diagnostics will test for valid SKSE installation on each game load and display a warning if there is a problem.")
	endEvent
endState

This is an MCM State inside the script JaxonzDiagnosticsMCM (Scriptname JaxonzDiagnosticsMCM extends ski_configbase if you are wondering) script.

 

JaxonzDiagnosticQuest is a separate script (derives from Quest).

 

I have no idea how 

 

 

((Self as Quest) as JaxonzDiagnosticsQuest).bValidateSKSE = bValidateSKSE

 

works. Cast Self to Quest, then to a different script type and then access a property on that script. 

 

Is there some arcane rule about how the "as" operator works between object (script) types?

 

Thanks

UIExtensions dev did the same trick. It-Just-Works

It seems that the one quest have few scripts attached thus the cast returns another script instance

 

Btw

function blabla()
  t = 0
  int t = 1
endfunction

Papyrus is about as a fucking crazy as Javascript.

I heard of Javascript issues, but I wish it would Javascript instead
