Detecting files in the RTP itself

[DerVVulfman]

That... is the question...

While the file_exists function/statement allows you to check on files in your game's project folder or in a folder/pathway specified in your filename, I haven't seen or heard of a RGSS method for checking the existance of files in the RTP itself.

Anyone got any clues on doing so? I really would like to know... for error checking routines.

Wouldn't it work giving the full path to check? Like this:

if file.exists?("C:\Program Files\Common Files\Enterbrain\RGSS\Standart\Graphics\Autotiles\001-G_Water01")
  # commands
end

I don't see why it wouldn't, though it's possible I made some errors writing the path ^_^

 

[Mr.Mo]

you don't have to write all that

if File.exists?("Graphics\Autotiles\001-G_Water01.png")
# commands
end

just that is fine. That works for me anyways.

btw, it won't work in encrypted projects

Edit:
I've re-read your question.. BlueScope is right in that case.

 

[Me(tm)]

Atually, he is not You can Install the RTP on different places, so that won't work. Actaully, there IS a global variable wich tells you the place of the RTP (If I recal correctly, something similar to %SYSTEMROOT%)...

But whatever, I would use: (example a picture):

begin
Bitmap/Sprite.bitmap = Rpg::Cache.picture('filename')
#exists
recue Errno::ENOENT #Captures File does not exists exceptions
#does not exists
end

@Me: I suppose, it'd be 'rescue', not 'recue' ^_^ Well, let's say I'm sure ^_^

But %SYSTEMROOT% should be the string that replaces C:\WINDOWS\system32\ , nothing more... maybe Enterbrain included a specific string for their RTP, but it's surely not this...

Heh.

Meâ„¢'s technique may be just what I need. Can't use the directory/pathway technique cause it can change dependant on where the RTP is set up. Thanks for the head's up on the encrytion Mr.Mo. Didn't check.

Will return when I get off of work (on Sunday) ... blah....

EDIT at 9:45PM (my time):

I took a look in the help file, and while testing with RPG::Cache will work for pictures and such, it won't work with music files (which unfortunately is what I need it for). And using the File.exists? works just the same way as FileTest.exist?(, only testing what is in the project and not in the RTP.

The RTP installer creates a string value containing the RTP name in the "HKEY_LOCAL_MACHINE\SOFTWARE\Enterbrain\RGSS\RTP" registry key and uses it to set the path. RGSS recognizes the string specified in this key as the RTP.

Perhaps, someone knows how to access the registry???? ...Yeah... right... ':|

Doing some tinkering with the AudioFile class in module RPG, I came up with this... http://www.dubealex.com/asylum/style_em ... ex/cpu.gif[/IMG]

   begin
     @trd = RPG::AudioFile.new("026-Town04")
     Audio.bgm_play("Audio/BGM/" + @trd.name,1,100)
     print "Woohoo!"
   rescue Errno::ENOENT
     print "Waahhh!  Not there!"
   end

That's @trd as in I'm tired... http://www.dubealex.com/asylum/style_em ... /sleep.gif[/IMG] ... it's almost 1:00 am my time.

This little #$%^ plays a millisecond of the track I'm testing right now, but it IS testing 'BOTH' what's in the RTP and in the project folder. No file extensions necessary! http://www.dubealex.com/asylum/style_em ... /yahoo.gif[/IMG]


Thanks guys. This should come in handy with some audio-system add-ons.

EDIT:
Mimi's Battle Music now encorporates this system to prevent errors from crashing the game when a music file is called and doesn't exist. Again. Thanks for the help!
