Well... 570k is compromised of the EXE, and SDKs which are used. So, whatever SDK he is using should be the main contributor to this. I'm sure he has already optimised his plugin as much as possible before releasing.

@Mnemonix
I must say that the whole "Age of broadband" thing was a bit rude. Many people only have enough money to use a 56k dial-up modem internet connection. (Even though, I do have broadband) No offense intended.

It wasn't meant to be rude. Even on 56k its only going to cost a couple of minutes extra in time, but what it costs in size it makes up for in its ability to compress other game assets, so once any assets being compressed have lost 570kb off their original size, your doing ok

Sorry if this seems like a daft analogy. I didn't let the size of the resulting plugin be a factor during development as I didn't expect the size of the plugin to detriment the usability of it.

@Mnemonix - Could I ask you to send me a unique copy of your dll so I can efficiently protect my FPS engine. (check my profile for my e-mail)

Thanks in advance,
I really look into wokring with your plugin.

Argh, I forgot those memblocks, now it works!
Thanks DB user 2006+, you are Einstein!

It seems to handle only 256x256, 512x512 etc images. Not even 256x512

Thank you. As for only handling square power of 2 images, it would seem that asking for a fix to this is a lost cause considering that this project appears to be dead.

Too many fine ideas and nice dlls seems to be interrupted when they are 90% ready.

Someone c++ student should make working crypting and packing dll. There is even well working and free zlib.dll http://www.zlib.net/ which someone could include or wrap to DBPro.

I used zlib in this project.

I promise I will complete this project eventually and try and work out the little bugs that are in it!

Yea, the MD5 functionality is already there, just needs to be wrapped in. Sorry I have not had much access to my development pc lately, and im on holiday as of tomorrow, so don't expect anything for a couple of weeks

I'm really glad to see that this thread is alive - this plugin is great as-is, but I too would like to see it finished. By the way, Great Job Mnemonix!!!

One of the things a couple of people have brought up is that a poorly designed key might be easy to find in a HEX editor. A real common solution (not saying this is the best solution, mind you) is to make a key that, in HEX, looks just like another section of your code.

You could, for example, use something like this as your key:



Well, you'd probably want to do something a little longer and more elaborate than this, maybe even copy/pasting a real loop that's used a lot in another part of your program ... but that's the BASIC idea. Once this compiles, it'll be practically impossible for a l33t h4x0r to find it in the HEX dump

Omen, that wouldn't work as it is because the actual DBP code gets translated to machine code, so it doesn't look like that anyway. I get what you're saying though.

i dont really understand how it prevents people stealing media, wouldnt the media be installed with the exe and then pointlessly placed into a protected file when the game runs? (or do you use an exe with all media inside it)

You can EASILY get data out of the DBP EXE. the_winch provided a tool, I made a tool, etc. DBP's EXE stuff is pointless.

Excellent! This DLL is proving to be more and more useful. One question: how would I make it so it could print the entire contents of a file? I tried doing it with a while loop, like this:


However when it is finished reading the contents of the file, it churns up an "Unexpected error was found in" my exe. I'm thinking it has something to do with trying to read a string that doesn't exist, but I don't know any way to get around that. Can you help?

Oh wierd, i didn't know anyone else was doing encryption for DBP

Games 2 Live, you probably need to use..



I've got a text file encrypter/decrypter and rolled it up into a simple to use function like...

EncryptTextFile("unencrypted.txt","encrypted.txt")
DecryptTextFile("encrypted.txt","decrypted.txt")

but people are complaining it makes large files. Does anyone know how i can save DWORD as binary to a file instead of saving them as HEX strings?

My little project is here:
http://forum.thegamecreators.com/?m=forum_view&t=109067&b=5&p=0

In return I've posted a link back to your project. Hope you don't mind.

when I download the file and try to open it it says "Unexpected end of archive" or something what's wrong with this?

Probably just a corrupt download. Also, this project seems to be pretty dead.

A verry usefull DLL, now all I need to do is write a function to export all my objects into meshes seperating there limb's into meshes to be reattached at load time. Anyone done this already?

Oh think I have spotted an error, if you try:-

I have attached the offending bitmap.


at least on my vista system it crashes.
I haven't tried it out on any other real small textures, this is a 8x8 and may be too small to work correctly.

keep up the good work!

Sorry to say this, but I lost the sourcecode like an idiot.

Soon I will be working on a database plugin though
