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.

KyleRunner: "difficult thing about the army": I'm very good at taking orders, so I don't have issues with autority or discipline. The most difficult thing is to be away from my family sometimes. I lived an entire year away from my son, so I'd say that was the most hard part by far. Now it's great!

Fox: That's good to hear... just checking if there were any possibility of doubt. What would you say was your most difficult thing about the army?
February 18, 2018, 12:39:38 PM
KyleRunner: Well, it was a destiny kinda thing, but I was very happy when I decided to join. It was just like I thought it would be (not in the beginning, though). I'm very pleased with my decision.
February 17, 2018, 11:32:41 PM
Fox: That's awesome!  Trying to figure what question I want to ask Something about how you felt when you made the decision to do the army, and whether it was different than your expectations/etc.
February 17, 2018, 01:53:41 PM
KyleRunner: Wow... My english got rusty. Anyway... I'm in the army now. My life turned 180. But I think it was for the best.
February 16, 2018, 12:45:45 AM
Fox: Hm? So where does that make you today?
February 16, 2018, 12:06:38 AM
KyleRunner: Five years ago I could not even imagine where I am today. I hope it works well for you too!
February 12, 2018, 07:22:50 PM
Fox: 2018 - The year that I will probably be working a manufacturing job. xP What would I have thought, if I told myself this five years ago. Eh?

Fox: You referring to changing the PC/leader sprite to someone else? - I forgot to mention that you can do this using VBA's memory viewer. (Found under Tools.)

January 25, 2018, 09:57:44 PM
Fox: Hm... Actually, this gives me an idea! What if the lighthouse becons on each lighthouse were actually portals?
January 25, 2018, 09:56:19 PM
Fox: Hard to explain without a diagram or something... but I could decide on that later. Right now, it turned out I dreamed of something! Something to do with going into the dark dimension... and to go between light and dark, required some energy (energy sphere/warp portal?) to be on... I forget most of the details of the dream now, but it's like you could get trapped in the dark world. Er...
January 25, 2018, 04:56:04 PM
KyleRunner: Can't understand... but... nice!
January 24, 2018, 06:20:33 AM
Fox: Third approach idea = Scan char tables and set up an array that helps to quickly jump over bits that are scanned in the char tables.... to kind of mimic an actual tree a bit better/ and reduce unnecessary scans.).... (untested, but what to know what it's speed is like.)
