Checking Files

Is there a way to check if a certain file exists on the server before its downloaded by the player? With a script of course..

hmm, downloaded as in see the image and poof have it in your graal directory or downloaded by gupd package?

Before its downloaded in any way. When its in the Graal folder, I can check it with ->

PHP Code:


		
			
filesize(string)

Or something else. But I want to check if it exists and is downloadable from the server before the client tries to do that.

I don't think it's possible to check that

Ok, lemme explain further :P I want to script a head changing system like on GK, something similar to "/head #". But I dont want to allow images which dont exist. How would I do that then? :/

use fileexists? :)
Or was you hoping for something built-in or on the clientside?

Give (npcserver) read rights to your heads folder, and use this to check if it exists:

PHP Code:


		
			
function doesFileExist(file)
{
  file.loadLines(file);

  if (file.size() >= 0)
  {
    return true;
  } else {
    return false;
  }
}

Last time I tried fileexists() it didn't work, but that was outside the levels folder, perhaps you will have more luck with a downloadable file.

The recommended function to use is
headexists(filename) - tells you if the image is downloadable and can be used as head for the player

I had the same problem for my system to check if an image didn't exist on an external webserver (like a website). I was shocked when I found out that Graal can't check that. x_X

A clientside function for checking if a file can be downloaded would be nice...
I hate using getimgwidth() when showing an image and having it be wrong because the image isn't downloaded yet...
