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.

Remember kids! Before you go on that interview, remember to wash your hands in teawater! *Coughs on hand* (Excuse me, I just coughed up a little teawater, so they're still clean!) You wouldn't want that hiring manager to be unimpressed.

May the force be with you!
Shoo! Why does it smell in here?
Maybe that's the wrong kind of force. *smirk*

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.

Fox: Aw.  I kind of want to suggest dressing up in a banana costume.  No wait, that's a bad idea.

Average Wind Seer: *angry gorilla noises that roughly translates to "Stay the [redacted] off my island and don't touch my [redacted] bananas"*

Fox: Gosh. This is like playing whack-a-mole! What's taking you so long with the bananas?! :D
February 28, 2019, 10:20:28 PM
Fox: And that other guy I thought for sure I saw a moment ago.... maybe he left again.
February 28, 2019, 10:16:29 PM
Fox: :O Wha-? I guess you didn't bring an army? If you plan on bringing a bunch, I would have suggested recruiting more people. Like me.
February 28, 2019, 09:57:15 PM
Average Wind Seer: I just reached the Island, but I'm planning on getting as many bananas as I ca- OH GOD!!! OH NO HE'S GOT ME!!! SOMEONE PLEASE HELP ME!!! AAAAAAHHH!!! NO! NO! NOOOOOOOO-!! *angry gorilla noises are heard as audio fades to static*
February 28, 2019, 09:13:45 PM
Fox: Huh. I didn't know you like going on adventures, that sounds interesting. How many bananas are you bringing?
February 28, 2019, 02:32:28 AM
Average Wind Seer: a brilliant plan. I'll go get the bananas from that seemingly uninhabited island with a large sign with the letters "D.K." written on it
February 28, 2019, 02:19:23 AM
Fox: I have an idea. If it turns out they love bananas, we can get some more as bait to keep them here?
February 27, 2019, 03:00:14 AM
Average Wind Seer: They consumed so much of the banana that only the essence of the peel remained TT^TT
February 27, 2019, 02:17:50 AM
FoxYou don't see it in the trash can over there?  Maybe that was someone else's.  .... Wait, Essence of Banana Peel?
February 27, 2019, 12:06:56 AM
Average Wind Seer: nope, that's just Essence of Banana Peel that they left behind :(
February 26, 2019, 11:39:52 PM
Fox: That's unfortunate.  I think they left the peeling for you.  :/
February 23, 2019, 05:18:08 AM
Average Wind Seer: .... yes.... I was gonna eat that banana....
February 23, 2019, 02:47:39 AM
Fox: steal*
February 23, 2019, 02:47:31 AM
Fox: Did they still your banana?
February 22, 2019, 02:32:19 AM
Average Wind Seer: hecc my ba- oh snap there they go :/
February 21, 2019, 10:14:10 PM
Fox: Shh... Don't scare them away.
February 21, 2019, 07:20:30 AM
Average Wind Seer: shocking, isn't it
