So the other day I was talking with my Programming teacher and an idea came in my mind.
"Let's load image in game from the game's code."
So the idea follows - We take the image's data and transform it into HEX code. Then we write an array of each hex value for the image, then we load the image from Array into the game and we have our sprite.

Wait, so we load an image and then save the image to the game again?

It sounds like a cool idea, though I'm afraid I am still lost on the reason for doing this. Would you mind elaborating a bit?

I just came up with such idea, well some engines do not compress images etc. and hackers can easier MOD the game. This way they don't, AND if they were to edit your code, they would have to recompile it, and you can add uncompleted code there, which at first does nothing but serves as the defense system of the game, and we can punish the players for hacking

@ 1st post:  Yep. I do believe that is the way you do it.

@ Last post: I see it more as a way for hiding information / decluttering the user experience rather than anti-hack, but okay. (Maybe anti-hack for the inexperienced, though...) Closest I can think of to anti-hacking is a server+client approach that requires an internet connection. Any sensitive data (e.g. Save data) could stay on the server. (That being the server isn't on the player's machine, but the client connects to it.) But of course... if one is going to build a server+client thing... then there's the possible issue of DDOS and such... so, eh. It's never that simple.

Anyway... the client should only send input data like mouse clicks and keyboard presses... and receive image data/audio data.... in best case circumstances... but that's probably a lot of data, though... (graphics/audio), so probably not recommended. But if it was done... I recommend a small resolution (e.g. 240x160=0x9600 pixels)that could possibly be zoomed in to full screen. (So less data is sent across the internet than otherwise.) As for music... I'd say just send the audio file over to the user... As people will probably document it anyway. And less internet traffic=better.)
@My idea:  I can see its potential for a 4-player game, maybe... but a large MMO, probably not. - In that case, image caching would be the way to go, most likely.

It's more of like a message, don't mess with this engine, I don't like what you're doing, I.E. Easter egg.

Wait, so you want the potential for a hacking community dedicated to hacking the game to make it harder to hack the game? :o

Or do you mean in general, like as a security feature for other games or sites?

A message? Might as well spell out to them.... that you are the copyright holder/etc.

But anyway... in the situation where a program is not open-sourced... data/images that are stored outside the program can still be checked against a checksum/signature type thing... if they need not be edited by a user. If editing was the main concern and not necessarily exposure/etc. But that's more me just speaking of an alternative. (That is definitely not foolproof. But then again, neither method is.)

Now I wonder if it is possible to encrypt a file using certain built-in techniques... and make it so one's own program can decrypt it... but only into RAM. (Without actually grabbing any encryption related code yourself.)

Okay pretty nice.
But what kind of format are you going to use? I guess that would be the first step in this problem.

Now that I think about it, you might only need to specify a width for the image and then simply just load RGB values, which makes an extremely easy format.

Salanewt: That's awesome! I'm pretty good; been working on an AI Overhaul project and have made some nice progress in the past couple weeks; the goal for tonight is to add Deadbeard to GS2 and then I can move onto something new.

Awec: Ye not bad, just checked back in for updates on GS Reloaded really. Although now I'm looking back through some of my old forum posts, which is fun :D how are you?

Salanewt: It sure is! How have you been?

Daddy Poi's Oily Gorillas: I'm having a thought. So I know Atrius's editor is slow at saving sprites.... So I've been thinking.   I am considering another console program.  This time, for importing and exporting sprites/animations. Image files (for sprites), binary files (for animation data), and maybe binary or text files for Settings. Would certainly be cool if it works out. - Console programs are fun, when you can (at least temporarily) cheat out making a full interface editor for them. =P

Daddy Poi's Oily Gorillas: (low as in <100)
25, April, 2020, 08:00:04 PM
Daddy Poi's Oily Gorillas: So while there are quite a few GS Communities out there. There are only up to maybe ~6 Discords worth even the consideration of joining, I think. Most of the rest of them have a fairly low member count. (Of which I can tell?)

Atrius: Whelp, there it goes... Just what I didn't want.  Have fun with that I guess...   
19, March, 2020, 05:20:25 AM
Daddy Poi's Oily Gorillas: So like. Replace the "e" with another "e"? Alright. Gotcha.
