Hallo zusammen, ich frage mich, ob es möglich ist, den Musik-Ordner beim einem Ace-Spiel später unzugänglich zu machen. Oder wenn nicht, zumindest unsichtbar.
Ich habe mir nämlich jetzt jemanden ins Boot geholt, der mir einen Soundtrack komponiert und ich möchte nicht, das ich die Tracks später in irgendwelchen Musik-Sammlungen auf dubiosen Ressourcen-Seiten wiederfinde.
Komprimierte Musik in verschlüsselte Archive hineinzucrypten und nochmal negativ zu komprimieren
endet im Performancechaos, wenn die Festplatten deiner Spieler versuchen, auf das Audiomaterial
vernünftig zuzugreifen. Die Ladezeiten sind mitunter für MP3 und OGG schon so astronomisch
SCHLECHT, es ist nicht ohne Grund, dass eb!'s RGSSAD-crypting solch derartige Verpackungs-
prozeduren nicht unterstützt.
Ein Trick den ich auch benutze wäre die Musik auf 200% hochzupitchen und dann mit 50% Speed abspielen. Das ist etwas Schutz zumindest und die Musik wird dadurch kleiner komprimiert. Nachteil ist evtl. die etwas schlechtere Qualität der Musik. Probiers aus, bei mir klingts fast gleich gut.
Hm, hatte mir leider schon sowas in der Richtung gedacht. Aber danke, ich werde es dann trotzdem mal probieren, vielleicht gehts ja noch einigermaßen.
Gruß
Ich hab was für den RMXP gefunden der dieses Problem lösen dürfte:
Ich weiss allerdings jetzt nicht in wie weit man es für den VXAce umschreiben müsste....Code:##########################################################################

# Script by: BEHEMOTH # #
####################### #
#Version: 1.0 #
#Date Created: October 26th 2006 8:42 PM (Eastern Standard Time) #
#Description: An encryption script for audio files. #
#Thanks goes to thephantom from http://www.phanxgames.com/ for pointing out #
#the whole encryption key idea which I was too blind to see. #
#############################################################################
#############################################################################
# ***IMPORTANT RESTRICTIONS*** #
#1) If the audio file is an .mp3 file, it will NOT encrypt the file and it #
#will play it normally. If you wish to have your mp3 file encrypted please #
#save it as another compatible audio file, such as .ogg, .mid #
#or .wav(compressed of course) or .wma #
# #
#2) Your audio files must NOT be: read only, or hidden, or protected in #
#anyway or it will not encrypt the file and it will play it normally. #
# #
#3) Audio files should not have the same filename with a different #
# extension. #
# BAD: "battle01.mid" "battle01.ogg" #
# GOOD: "battle01.mid" "battle02.ogg" #
# #
#4) Files from an RMXP RTP will not be encrypted and will play normally. #
#############################################################################
#############################################################################
# ***NOTES*** #
#Positives: #
# - Protects your own custom audio files #
# - Gives a point to having a BGM test inside your game #
# - Ummmm.......it's cool #
# #
#Negatives: #
# - Audio files take slightly longer to load #
# - mp3 files do not encrypt #
# - Once encrypted, audio files will not play in rmxp gui, only in the game #
# - The audio file is slightly bigger in file size then the orginal file #
# #
#If you have problems, suggestions, comments about this script then you can #
#currently find me here: http://www.phanxgames.com/forum/ #
# #
#How to Use: #
#To encrypt your audio files play the file in your game at least once. #
#The script will handle the rest. MAKE SURE TO BACK UP YOUR ORIGINAL #
#AUDIO FILES BEFORE ENCRYPTING IT, because it automatically overwrites #
#the original file with the encrypted file. To make this script encrypt #
#only certain audio files such as BGM, BGS, ME, SE then change the values #
#of the variables below named: #
#ENCRYPT_BGM, ENCRYPT_BGS, ENCRYPT_ME, ENCRYPT_SE #
# (located below class Game_System) #
#changing the value to true means those files will be encrypted and false #
#means those files will not be encrypted. Changing these values when an #
#audio file is encrypted may cause undesired results. So choose what you #
#want first then start encrypting your audio files. Deleting the Encryption #
#key file (default = "audio.edat") after encrypting your audio will also #
#result in undesired results....so don't delete or move that file once #
#you've been encrypting or else you'll have to start encrypting all your #
#audio again. This script is more for people who create their own audio #
#files. #
