Title: Need help squirrel function "file exist" working only on f.e. startup
Post by: qqplayer on March 25, 2018, 09:52:34 AM

I made this function , the final goal is to show a "pdfIcon" when you have the game manual on the selected folder "pdffilepath"

Code: [Select]

// pdfIcon

local pdffilepath="H://Attract//layouts//Basic//pdf//";
local game_name = fe.game_info(Info.Name);
local pdffile = pdffilepath + game_name + config["extension"];

local littlepngicon = fe.add_image( "manual.png", 0, 0, 200, 200);

fe.load_module("file");
function file_exist(pdffile)
   {
   print(pdffilepath + game_name + config["extension"]);
   try {file(pdffile, "r" );return true;}catch(e){return false;}
   }

if (file_exist(pdffile)) littlepngicon.visible=true
else  littlepngicon.visible=false;
Thanks to Daimon , Oomek and the other people who helped with the code.

As I said , only works when I start the frontend, If I start AM and the last selected game has the pdf manual the icon shows.
But when I move between the diferent games it doesnt change.
I mean if appears when I start the f.e. keeps showing all the time and if I selected a game who doesnt have the pdf manual - close A.M. - and open it again the icon is gone and doesnt shows anymore even if I move to a game who has the pdf manual.

Any help?

I am not a pro, but don't you need to use a transition callback? Something like "to new selection"?

I made the transition callback but doesnt work , just to test:

Code: [Select]

//pdfIcon

local pdffilepath="H://Attract//layouts//Basic//pdf//";

local littlepngicon = fe.add_image( "manual.png", 0, 0, 200, 200);
littlepngicon.visible=false;

function file_exist( ttype, var, ttime ) {
 switch ( ttype ) {
  case Transition.ToNewSelection|Transition.ToNewList|Transition.EndNavigation:
  local game_name = fe.game_info(Info.Name);
  local pdffile = pdffilepath + game_name + config["extension"];
  print(pdffilepath + game_name + config["extension"])
  break;
  }
 return false;
}

fe.add_transition_callback( "file_exist" );
Is "printing" the right selected game but every attemp to check the "file exists" is broken the f.e.

Code: [Select]

fe.load_module("file");

function catch_file()
   {
   try {file(pdffile, "r" );return true;}
   catch(e){return false;}
   }

if (file_exist(pdffile)) littlepngicon.visible=true;

catch_file();

You are almost there, see:

//pdfIcon

fe.load_module("file");

function file_exist()
   {
   try {file(pdffile, "r" );return true;}
   catch(e){return false;}
   }

local pdffilepath="H://Attract//layouts//Basic//pdf//";

local littlepngicon = fe.add_image( "manual.png", 0, 0, 200, 200);
littlepngicon.visible=false;

function mytransition( ttype, var, ttime ) {
 switch ( ttype ) {
  case Transition.ToNewSelection|Transition.ToNewList|Transition.EndNavigation:
       local game_name = fe.game_info(Info.Name);
       local pdffile = pdffilepath + game_name + config["extension"];
       //print(pdffilepath + game_name + config["extension"])
       if (file_exist(pdffile)) littlepngicon.visible=true
       else  littlepngicon.visible=false;
       break;
  }
 return false;
}

fe.add_transition_callback( "mytransition" );
