Checking Files

[Crow]

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?

[Crow]

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...

Thanks a ton all of you
