Some questions

[KockaAdmiralac]

Hello,

Many of you may be informed about my presence on the forums.

I started making RGSS3 scripts about three months ago, so I'm not quite a newbie to all of the terms.

However, I have to ask some questions.

I please moderators not to close this topic when first two questions are answered, because I have the third, and the most complex one awaiting, and I can't really post the whole problem now.

So, let's start

1) Are files in encrypted archive rewritable?

That means, can I store Saves and such in the Data folder?

I suppose not, because it is ENCRYPTED, but just to make sure...

2) How to read Scripts.rvdata2 ?

I know that I can use load_data("Data/Scripts.rvdata2"), but the returned object is an array of arrays of some numbers, the script name, and some \xsomething\xsomething text.

So, when I worked in Python, you could just print those characters out, and it would display them.

But, in Ruby those \xsomething characters also have something to do with pack and unpack methods, I assume.

So, should I do something like

that_xsomething.unpack('something').pack('somethingelse')

and I'll be able to read it like that?

I know some scripts actually do that, like Estriole - Script Control, but I don't know that encryption method (is it really encrypted or?)

So, thanks for answering, sorry if posted in the wrong place or did something that mustn't, and please, I say this again, do not lock the topic after first two questions are answered.

I'm not sure about RMVXA, but in RMXP the scripts.rxdata used Zlib to compress the scripts. So you had some numbers, the script name, and then the actual source code was compressed with Zlib. To un-compress it, you had to call Zlib::Inflate.inflate(script). I'd guess that RMVXA uses something similar if I doesn't actually use that same method.

 

[Engr. Adiktuzmiko]

1) Possible.But by default saving methods, you cant overwrite them...

2) It returns an aray of arrays that has the scripts saved in quite a few ways. It has a key of sorts, an encrypted version of the script and so on...

 

[KockaAdmiralac]

Zlib::Inflate.inflate(script)That's just what I needed!

But, there is a bit of problem with reading the scripts...

I tried to put ALL scripts in ONE row, by adding ;'s at the end of every row.

(Comment Remover ran earlier)

At first, I did it by putting the result string in the file scripts.txt

Problem occurred when I tried to add the contents of the file to the script editor.

The script editor crashed.

Then, I tried to make the new Scripts.rvdata2 with this code :

data = load_data("Data/Scripts.rvdata2")str = ""data.each{|d|Zlib::Inflate.inflate(d[2]).split(/[\r\n]/).each{|s|str += s + ";"}}File.copy("Data/Scripts.rvdata2", "Data/Scripts.rvdata2.bak")f = File.open("scripts.txt", "w")Marshal.dump([25125893, "The BIG Script", Zlib:eflate.deflate(str)])f.closeNope.

When started Game.exe got an load script error, and when opened the scripts in RPGMVXA got an "Internal error."

Is it possible to do something like this?

And, my next question is....

How to make animations on Sprites?

I made a Sprite that inherits from Sprite_Base, and called start_animation.

Parameters were correct, and the correct methods were called (tested it by adding p "something" in the update_animation method), but nothing actually updated.

Is my Sprite invisible? I tried to set the Z value to 100000, and experimented with OX and OY, but nothing actually happened.

Thanks for your replies!

 

[MobiusXVI]

So why are you trying to read the scripts data? Knowing that might help us help you.

As for your Sprite question, did you make your own Sprite class? Or did you just make an instance of the sprite class?

 

[Engr. Adiktuzmiko]

Your marshal.dump seems to be missing the file where you're dumping...

As for animating, you need to update the sprite each frame of your scene (by calling SpriteObject.update if I remember right, don't have RM with me right now)... It won't update automatically ..

 

[KockaAdmiralac]

@Engr. Adiktuzmiko

Actually, I had to rewrite this code, and passing the file to Marshal.dump is just a rewrite mistake.

It was passed in the original code

I think I tried to call 'update' from the update method, but still didn't work.

@Mobius

I'm trying to make the scripts data very unreadable, just from curiosity.

It's also an another layer of securing the Game.rgss3a, if I want to add some encryption to the scripts.

I know, I know, it's stupid, it'll change basically nothing, but I'm still curious on how to do that

I'm trying to convert this :

def a do_something blah blah blahendto this :

def a;do_something;blah;blah;blah;end

And for the Sprite, my class is an instance of Sprite_Base.

 

[MobiusXVI]

Ok, after checking over the code you posted, I found one mistake. When you dump "The Big Script", you dumpped it as a single level array. Even though there's only one entry is still needs to be one level deep. So try changing: 

Marshal.dump([25125893, "The BIG Script", Zlib::Deflate.deflate(str)])

to

Marshal.dump( [ [25125893, "The BIG Script", Zlib::Deflate.deflate(str)] ] )

 

[KockaAdmiralac]

@Mobius

Oops, my mistake.

But now, when I try to start it, the Game.exe crashes with no error, just opens and closes, and when I try to open it with RPGMVXA, it crashes also.

Is there even a way to do something like that?

 

[MobiusXVI]

I don't know. I've done some work exporting scripts to text files, and importing them back in later after editing them with a text editor. I've never tried changing the content of scripts via scripting.

 

[KockaAdmiralac]

Hello again,

Back with another question, while for the Sprite question I'll post the code later.

Can I change what F12 does?

I deleted the possibility that F1 and F2 do something, and I managed to exit the game (not restart it) with F12 with this code :

#==============================================================================# ** RGSSReset#------------------------------------------------------------------------------#  Exception class providing notifications for when the F12 key is pressed # during game execution. Name changed from the hidden class Reset before RGSS2. #============================================================================== class RGSSReset < Exception  include KOCKA    #--------------------------------------------------------------------------  # * Aliases  #--------------------------------------------------------------------------  alias :kocka_random_alias_exception_8x3M :exception    #--------------------------------------------------------------------------  # * Raise Exception  #--------------------------------------------------------------------------  def exception(*args)    exit if DISABLE_F12    kocka_random_alias_exception_8x3M(*args)  end  endBut still, I can't rescue an exception from inside an exception, right?

I also managed to do thing with rescuing the exception in Main, but it still just reboots the game from Title, and does not clear the Scene before.

Can I just resume the rgss_main?

Or is the code for rgss_main provided on some way, so we can rewrite it and disable F12?

(Or is it Graphics.update method?)

EDIT: Tried some things, managed to disable F12, unless you spam it.

Looks like in EVERY SINGLE ENTERBRAIN'S METHOD THERE IS A CHECK FOR RGSSRESET and then throwing a new exception.

WTF????

Currently I stopped the F12 presses in Window.update, Graphics.update, Graphics.transition, Input.update, and still while spamming it's giving me errors (sometimes it even gives me errors in lines of comments!)

On the other note... is this legal?

EDIT2 : OMG!!! I GOT A BACKTRACE FROM RUBY INTERPRETER!!!

I was spamming F12 while trying to change scene to Scene_Load, and suddenly... BAM! An error window showed and Ruby logged the backtrace to the console.

WHAT IS HAPPENING???

 

[Engr. Adiktuzmiko]

About the previous problem:


It might be that your edit to the scripts file somehow changed or removed the line which initializes the game... Remember that initializing the game is also written in the scripts at the lowest most part.

 

[MobiusXVI]

Depending on what you want to do with F12, there are easier ways to accomplish them than digging around in Exception classes. If you change main to this:

$run_once = falsergss_main { unless $run_once $run_once = true SceneManager.run end }Then it will run the provided block on startup, but then when you press F12 it will exit. 

 

[KockaAdmiralac]

@MobiusXVI : I know, but what if I want to disable F12, like I did with F1 and F2?

@Engr. Adikutzmiko : I don't think it was that. Even if it was, I have no way to check it, because Script Editor is still crashing...

 

[MobiusXVI]

Out of curiosity, why do you want to disable it? 

Although it's not the prettiest method, one way of disabling the effect is to separate the SceneManager methods. So rgss_main looks something like this:

Spoiler

def rgss_main(&block) yieldresuce RGSSReset retryend

So anytime F12 is pressed and the RGSSReset error is raised, the method catches it and retries itself. This ends up calling SceneManager.run again which re-initializes the game. 

Spoiler

def self.run DataManager.init Audio.setup_midi if use_midi? @scene = first_scene_class.new @scene.main while @scene end 

But if you were to split that up into two methods like this:

Spoiler

def self.init DataManager.init Audio.setup_midi if use_midi? @scene = first_scene_class.new end def self.run @scene.main while @scene end 

Then you could initialize everything and just pass the 'run' method to rgss_main like this:

Spoiler

SceneManager.initrgss_main { SceneManager.run } 

Now whenever you press F12, the screen will flash black but execution will continue normally.

@MobiusXVI

Hey, that's a great idea!

It's just happening, that my Mouse script is crashing, because of 'disposed sprite', but I suppose I can add in the RGSSReset some disposal and re-initialization code.

(And I can make some screenshot processing to make that black screen more logic to player, if he ever presses F12 )

I know, I know, too many questions....

But, here is another one.

Let's suppose I want to use a default Ruby library not included in RGSS3, like Net (for Internet communication with Net::HTTP - yes, I know there is RGSS WebKit) or OpenSSL (for ciphering with OpenSSL::Cipher::AES - because XOR is just TOO WEAK)

But, Net module requires 'socket.so' and OpenSSL requires 'openssl.so'

Requiring those throws an error.

Next, I found out that FyxInput script is using LoadSo DLL, and loading it through Win32API

FenixFyreX made a script also, that implements loading SO's through require

It works for FenixFyreX's fyxinput.so, but for openssl.so it's not working and throwing an

LoadError: 127: The specified procedure could not be foundThis is the excerpt from FenixFyreX's script:

That means maybe Init_openssl method in the library does not exist?

Nope. Checked it.

In all Ruby libraries I think that method MUST exist...

Does anybody know what is causing the problem?

(FenixFyreX is not amongst us currently, so asking him would require an unlimited amount of waiting)

And thank you all for answering.
