Which Function is Faster?


Inte

Recommended Posts

I needed a function that would search an array for a specific value and return its index.
Came up with this,

INT Function iDDeFindStringIdx(STRING[] sArray, STRING sFind = "")
    INT iCount = sArray.Length
    INT i = 0
       While (i < iCount)
          If (sArray[i] == sFind)
	     RETURN i
	  Else
	     i += 1
	  EndIf
       EndWhile
  RETURN -1
EndFunction 

Would call it like so,

 iDDeFindStringIdx(sArray, sValue) 

But then I find that there is a Papyrus global function that does the same thing. :-/

 sArray.Find(sValue) 

So, which one would be faster and less expensive?

Don't know. You would hope that the native one would be, (but it is Skyrim).

 

Anyway hows about using the SKSE GetCurrentRealTime function for a test. (i.e. Get start time, call your function a few thousand times in a loop for the last value in the array, then get the end time, then calculate end time minus start time for the time it took and dump it to the console. Then repeat for the native function. )

Without having seen any of the actual papyrus code, I'd still guess that it works the same way. There are only a limited number of ways you can iterate through an array.

 

But like spoonsinger said, it's not a bad idea to run a test like that. It'll confirm one way or another.
