Check if File Exists

[Bill Bisco]

I want to write code in my TP2 file to check if there is an Erevain.CRE already in the override or bifed. If that CRE exists there, then I want to input some code. Else, if it does not exist I want to input a different Code.

 

Any help would be appreciated.

ACTION_IF (FILE_EXISTS_IN_GAME ~erevain.cre~) BEGIN

  // erevain exists

END

ELSE BEGIN

  // erevain doesn't exist

END

[Roxanne]

ACTION_IF (FILE_EXISTS_IN_GAME ~erevain.cre~) BEGIN
  // erevain exists
END
ELSE BEGIN
  // erevain doesn't exist
END

Here is an example of the above code from my tp2

 

ACTION_IF FILE_EXISTS_IN_GAME ~CMNikitr.cre~ THEN BEGIN

COMPILE ~SandrahNPC/Mods/NikitaSanBG2.d~

EXTEND_TOP

~cmnikita.bcs~ ~SandrahNPC/Mods/NikitaSanBG2.baf~

EXTEND_TOP

~cmmadel.bcs~ ~SandrahNPC/Mods/NikitaMadel.baf~

PRINT ~ Nikita NPC detected - Sandrah Relationship and extended Section plot added~

END ELSE BEGIN

EXTEND_TOP

~ar1000.bcs~ ~SandrahNPC/Areas/ar1000NoNiki.baf~

PRINT ~Nikita not detected - extended Section plot without Nikita added~

END

 

If my mod finds the existing cre, the new stuff is incorporated in it- ELSE - I create a new event to trigger from there. (This is just an excerpt but it illustrates what to do)

Thank you both for your replies. I have incorporated this code into my mod and will test shortly. I like your example Roxanne because you're altering your mod content based on whether or not another mod is installed. Very cool.
